Bluetooth: Create Custom Intent to avoid Force close.

Use Case:
1. Select a music file with Japanese charecters
2. Push to DUT.
3. Open received OPP file from inbound  list.

Failure:
"Unfortunately, Bluetooth share has stopped" error comes.

Root Cause:
Android added "println_native method" to log events of interest
in native library, this method not able to manipulate when message
contains special characters.

Fix:
Add a condition in CustomIntenet.toString() to remove special characters,
if it contains and return plain string to avoid force close.
