Redhat
At the step of Running your app I cannot run app from Eclipse. The command line way does not work.After several tries, it seems the RHEL does not have an updated Ant package (currently it is 1.7 but I need 1.8). Give up.
Ubuntu
Download the bundle version. The file name I got is <adt-bundle-linux-x86_64-20131030.zip>.
On 64-bit Ubuntu, we need to run
sudo apt-get install libstdc++6:i386 lib32z1 lib32ncurses5 lib32bz2-1.0
For both 32-bit and 64-bit, we need to get openjdk
sudo apt-get install openjdk-6-jre openjdk-6-jdk icedtea6-plugin
Then uncompress <adt-bundle-linux-xxx.zip> and run the file <eclipse> from either file manager or command line. It just works!
We can furthermore set up the PATH variable by editing ~/.bashrc file.
export PATH=$PATH:~/adt-bundle-linux-x86_64-20131030/sdk/platform-tools/ export PATH=$PATH:~/adt-bundle-linux-x86_64-20131030/sdk/tools/
Then source the file by
source ~/.bashrc

Qt + Android
Installation
- http://qt-project.org/doc/qt-5/android-support.html
- http://qt-project.org/doc/qtcreator-3.0/creator-developing-android.html
On Ubuntu we can install requirements by
- SDK -> No need to download a special copy. Just use adt-bundle-linux-x86-2013xxxx one.
- Apache Ant -> sudo apt-get install ant
- NDK -> android-ndk-r9c-linux-x86.tar.bz2. Use tar -xjvf android-ndk-r9c-linux-x86.tar.bz2 to extract.
- Download qt-linux-opensource-5.2.0-android-x86-offline.run and install it into a new location, eg ~/Qt5.2.0Android (Cannot be the same as Desktop version).
- On a new machine, we need to install opengl library as instructed here and here.
sudo apt-get install mesa-common-dev sudo apt-get install libglu1-mesa-dev -y
The Qt needs to change the setting from Tools > Options > Android where we can specify the locations of Android SDK, Android NDK, Ant and JDK. On Tools > Options > Devices, we can change the Device from default (Local PC) to Run on Android. See the instruction on qt.project.org. Basically we go to project's setting to do changes. It does take a little longer to get the app on device.

Check connected devices
Enable USB debugging on your device first.
$ sdk/platform-tools/adb devices List of devices attached 2011060116402004 device
Where to find the apk files on devices
See here. It is located under /data/app/.
Failed to install HelloWorld.apk on device (null) Error
Solution: Try changing the ADB connection timeout. I think it defaults that to 5000ms and I changed mine to 10000ms to get rid of that problem. If you are in Eclipse, you can do this by going through Window -> Preferences and then it is in DDMS under Android.
Build without running an application
Building vs running: Building will just generate apk file but running will install the app to the device.
See here. In Eclipse menu, Windows -> Preferences. From this Preferences window: Android -> Build. Now uncheck "Skip packaging and dexing until export or launch. (Speeds up automatic builds on file save.)". From now on, as long as we save any changes in source files, the apk file will be recreated.
