Turn device bluetooth on or off

Question

I want my button in android studio to check whether the bluetooth is on or off from the same button and then turn it on or off accordingly from the source code, can anybody help me out here?

What did you try so far? Can you include some code samples? – M B Jan 16 '18 at 17:22 — M B, Jan 16 '18 at 17:22

Firstly you need to add these permissions

<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

and to Enable/Disable Bluetooth programmatically use BluetoothAdapter for example:

btnBluetooth.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
if (adapter.isEnabled()){
                adapter.disable();
            } else {
                adapter.enable();
            }
} });

May I know plz, why location permission needed for this? I saw some other libraries also where they r using location permission for Bluetooth scanning. But not sure yet, why needed? – Ameer Apr 07 '20 at 04:27
