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

Just uncompress adt-bundle-linux-xxx.zip and run the file <eclipse>. It just works!

Qt + Android

• http://qt.apidoc.info/5.2.0-beta1/qtdoc/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.
• 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).

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.
