$ adb devices (to find port number 5554)
$ telnet localhost 5554
event send EV_KEY:KEY_MENU:1

fedora 10 - setup i686 environment for android (1)

0. install git ($ sudo yum install git)
1. Download JDK 5.0 (jdk-1_5_0_19-linux-i586-rpm.bin) from sun

   $ cd /usr/local
   $ /tmp/jdk-1_5_0_19-linux-i586.bin 
   $ sudo updatedb
   $ locate javac | grep bin
   /usr/local/jdk1.5.0_19/bin/javac          (the result)
   $ sudo /usr/sbin/alternatives --install /usr/bin/java java /usr/local/jdk1.5.0_19/bin/java 100 
   $ sudo /usr/sbin/alternatives --install /usr/bin/jar jar /usr/local/jdk1.5.0_19/bin/jar 100  
   $ sudo /usr/sbin/alternatives --install /usr/bin/javac javac /usr/local/jdk1.5.0_19/bin/javac 100
   $ sudo /usr/sbin/alternatives --config java

2 Play with curl

$ cd ~/bin (make sure ~/bin is in $PATH)
$ curl http:/android.git.kernel.org/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
$ cd ~/myspace/mydroid
$ repo init -u git://android.git.kernel.org/platform/manifest.git -b cupcake
$ repo sync

android notes - the process of development

0 installation and setup
1 create a project

$ android create project --target 1 --path ./demo --activity demo --package com.example.demo

2 edit source code ~/myspace/demo/src/example/demo/demo.java
3 compile with ant

$ ant -debug -verbose

4 run emulator with a script

#! /bin/sh
out/host/linux-x86/bin/emulator -verbose \
 -kernel prebuild/android-arm/kernel/kernel-qemu \
 -ramdisk out/target/product/generic/ramdisk.img \
 -system out/target/product/generic/system.img \
 -init-data out/target/product/generic/userdata.img \
 -avd myavd -sdcard ./sdcard.img -no-skin -no-boot-anim

5 install the application we have build

$ cd ~/myspace/demo
$ adb install bin/demo-debug.apk
$ adb install -r bin/demo-debug.apk (for reinstall)
$ adb shell
# logcat
# ps a (to get process id to kill)
# kill -9

That's on java side, on the android side,
1 setup

$ cd ~/myspace/mydroid
$ source ./build/envsetup.sh
$ lunch 1

2 build the project in android

$ cd ./frames/base/media/libmediaplayerservice
$ mm (it builds libmediaplayerservice library as an example)
$ cd ~/myspace/mydroid (go back to the root)
$ make snod (build the system image

then you can go back to run emulator with parameters specified in the script.
