我正在尝试制作一个可检索gps信号的应用程序（也在屏幕关闭时），但是遇到了问题。我收到以下错误：

我的课程（相关）如下：
（主要活动：）
公共类MainActivity扩展了AppCompatActivity {
private Context context;
private static MainActivity ins;
public final String TAG = this.getClass().getSimpleName();
public static ArrayList<ScannedDevice> scannedDevices;
public static ArrayList<String> scannedMacAddresses;

*/
if(!runtime_permissions()){

}
}
public void start_scan(){

});

}
@Override

}

和GPSServices.java
public class GPSService extends Service {
private LocationListener locListener;
private LocationManager locMananger;
public GPSService() {
}
@Override
public IBinder onBind(Intent intent) {
// TODO: Return the communication channel to the service.
return null;
}
@SuppressLint("MissingPermission")
public void onCreate() {
locListener = new LocationListener() {
@Override
public void onLocationChanged(Location location) {
Intent i = new Intent("location_update");
i.putExtra("longitude", location.getLongitude());
i.putExtra("latitude", location.getLatitude());
sendBroadcast(i);
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onProviderDisabled(String provider) {
Intent i = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
}
};
locMananger = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE);
locMananger.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10000, 0, locListener);
}
public void onDestroy(){
super.onDestroy();
if(locMananger != null){
locMananger.removeUpdates(locListener);
}
}
}
当然还有mainfest文件

我找不到我的错误，有人可以帮我吗？
