Android: Error on back press button

Hi,

We are programming an app in android for showing the integration between rainbow and our lbs solution to customers. But we found an issue when the back button is pressed in the main activity. The APP is terminated with these errors:

I/System.out: (HTTPLog)-Static: isSBSettingEnabled false

V/NativeCrypto: Write error: ssl=0x77493335c8: I/O error during system call, Broken pipe

I/RAINBOW: 26731  [INFO] DatabaseMgr - deleteOldTableEntry from table :room_contact_table count: 0

So, I assume we should do something with the rainbow connection, but not sure what.

Thanks in advance
