Need to specify RECEIVER_NOT_EXPORTED for Android 14.

package net.sourceforge.opencamera.remotecontrol;

import static android.content.Context.RECEIVER_NOT_EXPORTED;

import android.content.BroadcastReceiver;

import android.content.ComponentName;

import android.content.Context;

            if( MyDebug.LOG )

                Log.d(TAG, "Remote enabled, starting service");

            main_activity.bindService(gattServiceIntent, mServiceConnection, Context.BIND_AUTO_CREATE);

            // For Android 14 (UPSIDE_DOWN_CAKE) onwards, a flag of RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED must be specified when using

            // registerReceiver with non-system intents, otherwise a SecurityException will be thrown.

            // The if condition is for TIRAMISU as there seems no harm doing this for earlier versions too, but RECEIVER_NOT_EXPORTED

            // requires Android 13.

            if( Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU ) {

                main_activity.registerReceiver(remoteControlCommandReceiver, makeRemoteCommandIntentFilter(), RECEIVER_NOT_EXPORTED);

            }

            else {

                main_activity.registerReceiver(remoteControlCommandReceiver, makeRemoteCommandIntentFilter());

            }

        }

        else {

            if( MyDebug.LOG )

                Log.d(TAG, "Remote disabled, stopping service");
