I spent the whole weekend trying to get some messages of a database on Android, getting a lot of ANR (Application Not Responding).
I just found the problem. The database was damaged.
I've lost one weekend.

@BrianValente Namesake most unusual ANR and App has Stopped Working of android are related to dB and mostly the customised Android Os of Chinese phones...... also putting operations on the User Interface (views) result to this if operations aren't well
