I finally managed to obfuscate my Android application, now I want to test it by installing the APK file and running it on the emulator.
Let's suppose you have to install Facebook APK on your emulator.
You can use adb to install the APK to the running emulator in OS X like this:
./adb install ~/FBAndroid-2.1.apk
And on Windows, like this:
adb install %HOMEPATH%\FBAndroid-2.1.apk
Once complete, check the apps screen of the emulator to check that the app has been installed correctly. If you need to force the upgrade of this app from a previous version, add the -r flag, like this on OS X:
./adb install -r ~/FBAndroid-2.1.apk
