For Froyo (Android 2.2) onwards, include the ‘autoLocation’ so that application can be moved/installed to SD card. This can be very helpful in tight situations, particularly in the case of budget phones.
Remember to include ‘write to SD’ permission if you wish to make changes to the SD card.
When using the AndEngine, remember to include ‘WAKE_LOCK’ permission.
When new Activity classes are added to the project, remember to include them in ‘AndroidManifest.xml’. If this is not done, the activity will not launch, though no compilation error is indicated.
