java - Android: how to stop calling the same function while the function is running -

-

example: got button, if press call function fetch data api screen. how can stop calling function if user press again , function still running(processing).

instead of hiding button there way handle it? need use thread handle it? check if thread alive? not familiar that. please give me suggestion , example on how handle it.

sorry bad english. thanks.

make boolean turns true when press button. when true normal functions of method. make when person presses button again boolean turns false. when false make want break out or return or nothing.

android - getbluetoothservice() called with no bluetoothmanagercallback -

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
