USB permissions on the host
On the host, example how to solve permissions:
Create /etc/udev/rules.d/99-android.rules for Nexus phones:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0bb4", ATTRS{idProduct}=="0fff", MODE="0666", OWNER="<your_account>" # Nexus One Fastboot SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e11", MODE="0666", OWNER="<your_account>" # Nexus One Normal SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e12", MODE="0666", OWNER="<your_account>" # Nexus One Debug/Recovery SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e20", MODE="0666", OWNER="<your_account>" # Nexus S Fastboot SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e21", MODE="0666", OWNER="<your_account>" # Nexus S Normal SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e22", MODE="0666", OWNER="<your_account>" # Nexus S Debug/Recovery SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e23", MODE="0666", OWNER="<your_account>" # ???

Then execute /etc/init.d/udev reload
Restoring factory ROM (2.3.3)
Warning, it will destroy everything, make your backups first!!
- Get firmware here for a European Nexus S i9023, mine needs the I9023XXKB3 one.
- Rename tar.md5 as tar
- Get Odin sw from here, choose i9023
- e.g. I9003_Odin3_v1.82.rar & SAMSUNG_USB.rar
- Run Odin (works in a virtualbox if needed), load the 4 files:
- bootloader: I9023_EUR_GRI54_XXKB3/I9023_EUR_GRI54_XXKB3/Bootloader_I9023XXKA3.tar
- PDA: I9023_EUR_GRI54_XXKB3/I9023_EUR_GRI54_XXKB3/PDA_SOJU_GRI54_TMO_EUR_MR1_SIGNED.tar
- Phone: I9023_EUR_GRI54_XXKB3/I9023_EUR_GRI54_XXKB3/MODEM_I9023XXKB3_REV_00_CL912571_SIGNED.tar
- CSC: I9023_EUR_GRI54_XXKB3/I9023_EUR_GRI54_XXKB3/DGS_I9023_EUR.tar
- Turn phone off
- Plug USB
- Just before battery icon showing, enter download mode by pressing middle of volume up / volume down button for long, you'll get a big yellow warning triangle
- If using virtualbox, bring USB device (Samsung serial) to virtualbox
- Now Odin should show a yellow rectangle with COM0
- Press "start" in Odin

Restoring (most of) factory ROM (2.3.3) with fastboot
Ok previous section was about restoring *everything* as genuine but it requires Windows and most of the time all you screwed up was the boot image, the recovery image or the system image so here is how to restore them or part of them provided that you can still enter fastboot:
fastboot oem unlock # if needed fastboot flash recovery recovery.img # from Samsung PDA_SOJU_GRI54_TMO_EUR_MR1_SIGNED.tar fastboot flash system system.img # from Samsung PDA_SOJU_GRI54_TMO_EUR_MR1_SIGNED.tar fastboot flash boot boot.img # from Samsung PDA_SOJU_GRI54_TMO_EUR_MR1_SIGNED.tar
Warning: I got /sdcard content erased, maybe because I tried to enter the native recovery, but anyway, make backups first before trying anything you risk regretting!!!
E.g. to make a backup with clockwordmod:
- Put phone into fastboot mode
- Enter recovery
- Choose backup & restore / backup
- Choose mount / mount USB storage
- From host: copy clockwordmod/backup/*
Entering fastboot mode
- Power off phone
- Press Volume up and power button together for long
- You've entered fastboot
- Alternatively, fastboot can be triggererd from adb: adb reboot-bootloader
For getting fastboot on the host, see further below
Rooting 2.3.3
- copy su-2.3.6.1-ef-signed.zip (from http://forum.xda-developers.com/showthread.php?t=682828) on USB storage
- enter fastboot mode (see above)
- host: fastboot oem unlock
- fastboot flash recovery 3025-i9023.img
!! Don't touch boot image or try CW 3.0.0.0, one of them caused the phone to not start android anymore, I had to perform the full factory restore with Odin !!
- enter recovery mode from fastboot
- You can make a backup now
- install zip from sdcard -> choose -> su-2.3.6.1-ef-signed.zip
- reboot

Upgrading to 2.3.4
A new version was announced (fr) two days ago.
Official way is apparently to type "*#*#2432546#*#*" while using Wi-Fi but all I got was a "checkin succeeded" notification. Anyway patched won't apply cleanly on my rooted phone so better to do it manually.
For GRI54, update.zip is available here.
I tried to apply it but there are several caveats given the previous hacks:
- boot.img: to be able to patch it I've to restore the original boot.img, loosing temporarily the ro.secure=0 setting (cf "adb as root" paragraph). And failing to patch it would probably mean non-bootable as we would have missed replacing the kernel!
- radio.img: hash checksum failed, it seems to indicate that expected radio.img is not the one I have.
- recovery.img: we want to keep the clockworkmod one, so we just skip it for now
To apply those change this means:
- fastboot flash boot boot.img (from PDA_SOJU_GRI54_TMO_EUR_MR1_SIGNED.tar)
- edit update.zip to remove radio.img, recovery/ and edit META-INF/com/google/android/updater-script
- remove all commands about radio & recovery patch
- add following line to keep rooted: set_perm(0, 0, 6755, "/system/bin/su");
- if that line is not added, patched phone will not be rooted anymore, which can be easily fixed by applying the su..zip again
- upload update.zip to /sdcard and apply zip via clockworkmod recovery, it'll skip signature verification by default
Ok now we got a system & boot images upgraded to 2.3.4
We can again modify boot.img to restore ro.secure=0:
- Extract patched 2.3.4 boot.img (cf below, or use clockworkmod), modify it & flash it back
I also wanted to patch the stock recovery image, just to get a 2.3.4 stock recovery in case of.
- Install the 2 files from update.zip#recovery/ into /system and chmod 755 /system/etc/install-recovery-sh
- Restore the stock 2.3.3 recovery.img from PDA_SOJU_GRI54_TMO_EUR_MR1_SIGNED.tar: adb push recovery.img /sdcard/
- If you've flash_image on the phone you can try: flash_image recovery /sdcard/recovery.img
- Else:
fastboot erase recovery fastboot flash recovery recovery.img
- Reboot the phone & start Android
- It should be done, recovery should have been patched, you can remove the 2 files we've put in /system and extract the patched recovery image manually (cp /dev/mtd/mtd3 /sdcard/recovery.img). Hash changed so I assume it's properly patched
- Restore clockworkmod recovery image
What's new?
I didn't mention it but with 2.3.3 I had two problems I was still busy trying to solve: GPS never fixing, zero satellite! And no way to see I get copy-protected applications (and that's not because of rooting the phone, on a stock phone it failed too).
Now GPS fixed quite fast with 2.3.4 and I could for the first time see & download copy-protected apps \o/ (even when the phone was rooted again).
UPDATE
here is the full ROM update, apparently with a new radio which should be ok for all phones...
Seen in this thread.
Upgrading to 2.3.6
I saw there was also newer versions of ClockworkMod, probably better than the preview release I was still using.
Latest ClockworkMod recoveries are here.
For Nexus S, look for "crespo" img
- Go to fastboot (vol-up + power)
- Go to recovery
- Backup & restore / Backup
- Mount USB
- Copy all /sdcard content to PC
- Reboot -> enter fastboot again
- On PC: fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img
For GRJ22, upgrade.zip is available here
- fastboot flash boot boot.img (from stock GRJ22)
- edit update.zip to remove recovery/ and edit META-INF/com/google/android/updater-script
- remove all commands about recovery
- add following line to keep rooted: set_perm(0, 0, 6755, "/system/bin/su");
- because I've mangled cacerts.bks to add CACert stuff, I had also to remove stuffs about cacerts.bks in the script, then make a separate zip where I first restore the previous stock cacerts.bks from GRJ22 then apply the patch. And finally mangle the new cacerts.bks again.
- In updater-script, check also which radio version it's able to patch. Look for line similar to this one:
apply_patch("MTD:radio:12583040:2ea138c96cc213b2662a4ae1ddee2d5c6bbcc958:12583040:213c2022516ba651f62064e4379487af1e8499a2", "-", 213c2022516ba651f62064e4379487af1e8499a2, 12583040, 2ea138c96cc213b2662a4ae1ddee2d5c6bbcc958, package_extract_file("radio.img.p"));
Here it expects a radio.img from GRJ22 with SHA1 = 2ea138c96cc213b2662a4ae1ddee2d5c6bbcc958, ok
In case you don't have the right radio img in place, or don want to patch it, remove radio.img from the zip and all commands about radio in updater-script.
- upload update.zip to /sdcard and "apply update from sdcard" via clockworkmod recovery, it'll skip signature verification by default
- Backup & Restore / Backup
- Mount USB
- Copy new backup to PC
Ok now we got a system & boot images upgraded to 2.3.4
We can again modify boot.img to restore ro.secure=0:
- Extract patched 2.3.6 boot.img (cf below, or use clockworkmod), modify it & flash it back
Extracting manually images from phone
On root shell on the phone:
# cat /proc/mtd dev: size erasesize name mtd0: 00200000 00040000 "bootloader" mtd1: 00140000 00040000 "misc" mtd2: 00800000 00040000 "boot" mtd3: 00800000 00040000 "recovery" mtd4: 1d580000 00040000 "cache" mtd5: 00d80000 00040000 "radio" mtd6: 006c0000 00040000 "efs" # cat /dev/mtd/mtd5 > /sdcard/radio.img
etc
Android 2.3
Getting fastboot & Android sources
There are several binaries around but I wanted to build my own.
Maybe not the shortest way... I downloaded all android sources...
cf http://source.android.com/source/downloading.html
Some missing deps on my 64-but debian when I tried to compile everything: gperf, libc6-dev-i386, lib32ncurses5-dev ia32-libs g++-multilib lib32z1-dev lib32readline6-dev
. build/envsetup.sh lunch crespo-eng make -j2
Maybe we can just compile adb & fastboot:
make adb make fastboot
cf http://www.cduce.org/~abate/build-android-adb-debian-sid-amd64
Getting adb & Android SDK
Get it from http://developer.android.com/sdk/index.html
Run tools/android -> in installed packages make sure to have "Android SDK Tools", latest revision and "Android SDK Platform-tools", latest revision
It brings also adb but not fastboot
If you want to update SDK: tools/android update sdk
adb
You need to activate USB debugging:
- Settings > Applications > Development > USB debugging
Some examples:
- adb devices
- adb shell
- adb logcat
adb as root
Once the phone is rooted, you can, from a shell with e.g. adb shell invoke "su" & get root.
But to get immediately into root, the file /default.prop needs to contain ro.secure=0
But that file is restored from boot.img at each boot so you need to modify that one
See http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack%2C_Edit%2C_and_Re-Pack_Boot_Images#Alternative_Method
but there is also abootimg in debian:
- Taking the boot.img from Samsung (see above in I9023_EUR_GRI54_XXKB3/I9023_EUR_GRI54_XXKB3/PDA_SOJU_GRI54_TMO_EUR_MR1_SIGNED.tar).
abootimg -x boot.img mkdir ramdisk cd ramdisk gzip -dc ../initrd.img | cpio -i sed -i default.prop 's/ro.secure=1/ro.secure=0/' find . -print|cpio -o -Hnewc|gzip > ../initrd.img2 cd .. abootimg -u boot.img -r initrd.img2 fastboot flash boot boot.img
For the last command, the phone needs of course to be in fastboot mode
Reboot phone
I had to re-enable USB debugging but now adb shell brings me immediately a root shell :)
Note that link mentioned above proposes an alternative way to flash the boot partition, directly from adb shell as root
Without this setup, it's a bit cumbersome to automate root commands from host, it looks like
adb shell su -c "netcfg usb0 dhcp"
and the SuperUser app prompts you for confirmation on the phone for each new command
Got a failure when trying to flash back a 8Mb boot.img?
From example above I started from a boot.img smaller than the full boot partition but if you create a new boot.img or start from an image of the full partition taken manually or with clockworkmod, boot.img will be 8Mb-large (8388608) and fastboot fails with "FAILED exceed blocks 0x00000020 > 0x0000001e".
I'm not really sure about what size the file should be but as it's filled with zeroes till reaching 8Mb, I decided to cut it:
0x00000020 => 0x0000001e means for me 8388608 / 0x20 * 0x1e = 7864320, so I did:
dd if=boot.img of=boot2.img bs=262144 count=30 fastboot flash boot boot2.img
And it worked!
Images structure
You may want to explore .img content (from backups, stock ROMs etc).
Actually all .img are not the same
bootloader.img
/dev/mtd/mtd0
Unknown format
radio.img
/dev/mtd/mtd5
Unknown format, for baseband
recovery.img
/dev/mtd/mtd3
Unknown format
boot.img
/dev/mtd/mtd2
See here for details on the structure, and abootimg on Debian
system.img
Yaffs2 image, can be unpacked with unyaffs
Note that unyaffs failed unpacking stock system.img 2.3.3 & userdata.img but works fine on clockworkmod backups
data.img
Yaffs2 image, can be unpacked with unyaffs
cache.img
/dev/mtd/mtd4
Yaffs2 image, can be unpacked with unyaffs
misc
/dev/mtd/mtd1
Not backuped by clockworkmod
efs
/dev/mtd/mtd6
Yaffs2 image, can be unpacked with unyaffs
Not backuped by clockworkmod
Contains stuffs linked to baseband & bluetooth
Screenshots
Run ddms (from SDK) -> Tools / Device / Screen capture
USB tethering
Plug phone & PC via USB
Activate USB tethering (Settings / Wireless & networks / Tethering / USB Tethering)
It works OOB on Debian, nothing to do
Getting busybox
Need rooted phone, see above
Google's stripped busybox, called toolbox, is far from enough once you get a shell on the phone
- Get Busybox Installer from Market
Examples to use busybox versions instead of toolbox versions when the command exists twice:
# busybox mount -o remount,rw /system # /system/xbin/mount -o remount,rw /system
Wi-Fi & client certs
To be able to authenticate to a Wi-Fi network using client certificates via TLS:
If needed, export certificate from IE in Pkcs#12 PFX, *with* private key, *with* all certs, *without* strong enc, *without* deletion of private key.
Rename .pfx file as .p12
(source: http://www.google.com/support/mobile/bin/answer.py?answer=168466&topic=27214#1086573)
Copy pkcs#12 certificate to root of USB storage.
File must end with .p12, not .pfx!
One single file with key+cert+cacerts is ok
Wi-Fi params: 802.1x EAP / TLS / phase2: None / CA cert: cf previous import / user cert: idem / Identity: DOMAIN\user... / Anonymous id: empty / password:...
Note that after each reboot, you'll have to select manually one of the protected networks to unlock the secure storage of personal certificates or open manually the certificates storage:
Settings > Location & Security > Use secure credentials
See also Keystore Unlocker
Importing certs
I could only manage it via a webserver & crafted headers:
<?php header("Content-Type: application/x-x509-ca-cert"); ?> -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE-----
You may try this free service: http://www.realmb.com/droidCert/ which seems to do the same.
But even if imported they seem not to be used e.g. for IMAP TLS.
Importing CA certs in /system
Source: CACert wiki.
You don't need the full Android SDK, just adb binary.
I'm not sure if it's really the proper way but to get recognized the BouncyCastle lib which was already on my system (apt-get install libbcprov-java) I did
sudo ln -s /usr/share/java/bcprov.jar /usr/lib/jvm/java-6-sun/jre/lib/ext/
Adding CACert certificates:
adb pull /system/etc/security/cacerts.bks wget http://www.cacert.org/certs/root.crt wget http://www.cacert.org/certs/class3.crt keytool -keystore cacerts.bks -storetype BKS -provider org.bouncycastle.jce.provider.BouncyCastleProvider -storepass changeit -importcert -trustcacerts -alias CACERT -file root.crt keytool -keystore cacerts.bks -storetype BKS -provider org.bouncycastle.jce.provider.BouncyCastleProvider -storepass changeit -importcert -trustcacerts -alias CACERT3 -file class3.crt adb shell busybox mount -o remount,rw /system adb push cacerts.bks /system/etc/security adb shell busybox mount -o remount,ro /system
- reboot phone
- try https://www.cacert.org, should work without warning
Now my IMAP TLS which is using a CACert-signed certificate works with strict TLS setting on the phone, cool!
WARNING this has broken proper upgrades and I had to mangle the update.zip to restore first the original cacert.bks file then get it patched.
Before I patched it again, my imap server gave me a lot of "couriertls: read: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number" errors before I realized it was because I didn't' have the CACert certificates anymore...

Create your own maps with Mobile Atlas Creator (Java-based) & use them e.g. with RMaps, AndNav, Maverick, TrekBuddy,... (bitmaps so ok only for small areas such as cities)
- Get e.g. RMaps from Android Market
- Get latest release of Mobile Atlas Creator & unzip it
- Get latest SqliteJDBC library and copy it inside th eMobile Atlas Creator directory
- Run it (start.sh)
- Choose your source, e.g. OpenStreetMaps, Google Maps,...
- Select area: Right click to Drag, Scroll to zoom In/Out, Left click to select downloadable area
- Select one or more zoom levels, e.g. from 12 to 18 for all levels of details of a city
- Do “add selection” with a name of your choice
- Select “BigPlanet SQLite” from “Atlas Settings” (for RMaps, otherwise Maverick Atlas Format for Maverick etc)
- "Create Atlas"
- Download the .sqlitedb map into the phone SDcard/rmaps/maps
- Disconnect the phone
- Open RMaps and Menu > More > Settings > User defined maps > BigPlanet_maps.sqlitedb > Enabled Maps
- Return to main maps screen and then Menu > Maps > BigPlanet_maps.sqlitedb.
Applications development
Getting Android SDK
Instructions below are for linux, if you're running Windows please check the provided resource links for variants of the instructions.
Make sure you've Java Development Kit installed
apt-get install sun-java6-jdk
As explained above, get Android SDK from http://developer.android.com/sdk/index.html
Run tools/android -> in installed packages make sure to have:
- "Android SDK Tools", latest revision
- "Android SDK Platform-tools", latest revision
- a platform SDK, e.g. "Android 2.3.3"/"SDK Platform"
As we will develop from the command-line, no need for the Eclipse plugin
If you want to update SDK
- tools/android update sdk
- Then restart tools/android
Setting environment
We first define a number of things:
JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.26/
ANDROID_HOME=/home/phil/devel/00android/android-sdk-linux_x86/
PACKAGE=com.foo.mytest1
PACKAGE_SLASH=${PACKAGE//.//}
DEV_HOME=$(pwd)/mytest
We need also to define the target. To know what are the available targets:
$ ../../android-sdk-linux_x86/tools/android list target Available Android targets: ---------- id: 1 or "android-10" Name: Android 2.3.3 Type: Platform API level: 10 Revision: 2 Skins: QVGA, WVGA854, HVGA, WQVGA432, WVGA800 (default), WQVGA400 ABIs : armeabi
So here we'll define:
TARGET=android-10
Preparing and using emulator
Here is how to create a basic emulator instance:
$ANDROID_HOME/tools/android --verbose create avd --name MyNexusS --target $TARGET --sdcard 1024M
Later, to launch it just do:
$ANDROID_HOME/tools/emulator -wipe-data -avd MyNexusS &
If needed to delete it:
$ANDROID_HOME/tools/android --verbose delete avd --name MyNexusS
Android application in command-line
See http://geosoft.no/development/android.html
Preparing the working directory (based on the environment variables defined above):
rm -rf $DEV_HOME
mkdir -p $DEV_HOME/src/$PACKAGE_SLASH/
mkdir -p $DEV_HOME/res/drawable/
mkdir -p $DEV_HOME/res/layout/
mkdir -p $DEV_HOME/res/values/
mkdir -p $DEV_HOME/obj/
mkdir -p $DEV_HOME/lib/
mkdir -p $DEV_HOME/bin/
mkdir -p $DEV_HOME/docs/
Create a dummy keystore:
$JAVA_HOME/bin/keytool -genkeypair \
-validity 10000 \
-dname "CN=company name,
OU=organisational unit,
O=organisation,
L=location,
S=state,
C=country code" \
-keystore $DEV_HOME/AndroidTest.keystore \
-storepass password \
-keypass password \
-alias AndroidTestKey \
-keyalg RSA \
-v
Create a Manifest file, here with some examples of permissions:
cat << EOF > $DEV_HOME/AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="$PACKAGE"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-sdk android:minSdkVersion="2"/>
<application android:icon="@drawable/mylogo"
android:label="@string/myApplicationName">
<activity android:name="$PACKAGE.HelloAndroid"
android:label="@string/myApplicationName">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
EOF
Provide source code of an app, here a simple HelloWorld, using an icon file some_icon.png:
cat << EOF > $DEV_HOME/src/$PACKAGE_SLASH/HelloAndroid.java
package $PACKAGE;
import android.app.Activity;
import android.content.res.Resources;
import android.os.Bundle;
import android.widget.TextView;
public class HelloAndroid extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView textView = new TextView(this);
String text = getResources().getString(R.string.helloText);
textView.setText(text);
setContentView(textView);
}
}
EOF
cat << EOF > $DEV_HOME/res/values/strings.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="myApplicationName">Android Test Program</string>
<string name="helloText">Hello, world!</string>
</resources>
EOF
cp some_icon.png $DEV_HOME/res/drawable/mylogo.png
Create R.java:
$ANDROID_HOME/platform-tools/aapt package -v -f -m \
-S $DEV_HOME/res -J $DEV_HOME/src -M $DEV_HOME/AndroidManifest.xml \
-I $ANDROID_HOME/platforms/$TARGET/android.jar || exit 1
Compile Java:
$JAVA_HOME/bin/javac -verbose -d $DEV_HOME/obj \
-classpath "$ANDROID_HOME/platforms/$TARGET/android.jar:$DEV_HOME/obj" \
-sourcepath $DEV_HOME/src \
$DEV_HOME/src/$PACKAGE_SLASH/*.java || exit 1
Create DEX:
$ANDROID_HOME/platform-tools/dx --dex --verbose \
--output=$DEV_HOME/bin/classes.dex \
$DEV_HOME/obj $DEV_HOME/lib || exit 1
Create APK:
$ANDROID_HOME/platform-tools/aapt package -v -f \
-S $DEV_HOME/res -M $DEV_HOME/AndroidManifest.xml \
-I $ANDROID_HOME/platforms/$TARGET/android.jar \
-F $DEV_HOME/bin/AndroidTest.unsigned.apk \
$DEV_HOME/bin || exit 1
Sign APK:
$JAVA_HOME/bin/jarsigner -verbose \
-keystore $DEV_HOME/AndroidTest.keystore \
-storepass password \
-keypass password \
-signedjar $DEV_HOME/bin/AndroidTest.signed.apk \
$DEV_HOME/bin/AndroidTest.unsigned.apk \
AndroidTestKey || exit 1
Zip-align APK:
$ANDROID_HOME/tools/zipalign -v -f 4 \
$DEV_HOME/bin/AndroidTest.signed.apk \
$DEV_HOME/bin/AndroidTest.apk || exit 1
Generate documentation, if you wish:
$JAVA_HOME/bin/javadoc -verbose -d $DEV_HOME/docs -sourcepath $DEV_HOME/src \
-classpath "$ANDROID_HOME/platforms/$TARGET/android.jar:$DEV_HOME/obj" \
-author -package -use -splitIndex -version \
-windowtitle 'AndroidTest' -doctitle 'AndroidTest' \
$DEV_HOME/src/$PACKAGE_SLASH/*.java
To install the resulting application in the emulator (see above how to launch the emulator):
$ANDROID_HOME/platform-tools/adb -e install $DEV_HOME/bin/AndroidTest.apk
It's even possible to launch & control application from the PC.
See http://learnandroid.blogspot.com/2008/01/run-android-application-from-command.html
$ANDROID_HOME/platform-tools/adb -e shell am start -a android.intent.action.MAIN \
-n $PACKAGE/$PACKAGE.HelloAndroid
To remove it:
$ANDROID_HOME/platform-tools/adb -e uninstall $PACKAGE
To do the same on a real device rather than on the emulator, make sure the phone is connected by USB and running in debug mode as explained above, then simple use -d (device) instead of -e (emulator), so previous instructions become:
$ANDROID_HOME/platform-tools/adb -d install $DEV_HOME/bin/AndroidTest.apk
$ANDROID_HOME/platform-tools/adb -d shell am start -a android.intent.action.MAIN \
-n $PACKAGE/$PACKAGE.HelloAndroid
$ANDROID_HOME/platform-tools/adb -d uninstall $PACKAGE
Simple java in command-line
