the graphicsdevicemanager class can handle of you:

    public game1()     {         graphics = new graphicsdevicemanager(this);         graphics.isfullscreen = true;         graphics.preferredbackbufferwidth = 1280;         graphics.preferredbackbufferheight = 720;          //...     }

now, have make sure you're drawing whole screen in spritebatch coordinates (base them on width & height).

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
