bluetoothGatt can't connect with target - Unhandled exception in callback

I tried to connect with my target device using Bluetooth GATT service, I got this message in console and can't connect.

I tried to connect by using this,

bluetoothGatt = mDiscoverderDevice.connectGatt(this, true, mGattCallback);

D/BluetoothGatt: connect() - device: 5D:BB:1E:F0:09:05, auto: true
 D/BluetoothGatt: registerApp()

I think it is not related to BLE. you are trying to update a view element like Toast or a TexetView from outside thread. thats why it says Only the original thread that created a view hierarchy can touch its views Try using runOnUIThread Method to update the UI Views.
