I have an application which uses the accelerometer, but only occasionally under rare circumstances. I'd like to preserve battery by having it disabled by default and only turn it on when needed.
Only thing I've found is setting configurations when initializing the app from this site
#Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
config.useCompass = false;
config.useAccelerometer = false;
MyGame myGame = new MyGame(new AndroidPlatform(this, config));
initialize(myGame , config);
}
But I can't find a way to enable/disable it while the app is running. Anyone have an idea?
EDIT:
In the above example AndroidPlatform is implementing a Platform interface in the core project. I tried out Zoe's idea of passing the config to platform implementation and changing it follows:
#Override
public void enableAccelerometer(boolean enable) {
config.useCompass = enable;
config.useAccelerometer = enable;
}
and then in the core project when the accelerometer should be enabled:
private void startInclineMonitoring() {
System.out.println("Before:");
System.out.println(Gdx.input.isPeripheralAvailable(Input.Peripheral.Accelerometer));
System.out.println(Gdx.input.isPeripheralAvailable(Input.Peripheral.Compass));
platform.enableAccelerometer(true);
System.out.println("After:");
System.out.println(Gdx.input.isPeripheralAvailable(Input.Peripheral.Accelerometer));
System.out.println(Gdx.input.isPeripheralAvailable(Input.Peripheral.Compass));
}
Unfortunately this outputs:
I/System.out: Before:
I/System.out: false
I/System.out: false
I/System.out: After:
I/System.out: false
I/System.out: false
So, no luck there.
It seems like there's no easy way to do this as of today, but I ended up doing my own (Android) motion sensor implementation. I thought I'd share it for future visitors:
This assumes you have your platform interface and platform specific implementation as explained in this wiki.
First these methods are added to the interface:
public interface Platform {
public void startMotionSensors(PlatformCallback<float[]> callback);
public void stopMotionSensors();
}
And in the android implementation:
public class AndroidPlatform implements Platform {
private Activity activity;
private MotionSensor motionSensor;
private Handler handler;
public AndroidPlatform(Activity activity) {
this.activity = activity;
this.motionSensor = new MotionSensor(activity);
this.handler = new Handler();
}
#Override
public void startMotionSensors(final PlatformCallback<float[]> callback) {
handler.post(new Runnable() {
#Override
public void run() {
motionSensor.start(callback);
}
});
}
#Override
public void stopMotionSensors() {
handler.post(new Runnable() {
#Override
public void run() {
motionSensor.stop();
}
});
}
}
The MotionSensor class:
public class MotionSensor implements SensorEventListener {
private Activity activity;
private SensorManager sensorManager;
private float[] gravity = new float[3];
private float[] geomag = new float[3];
private float[] rotationMatrix = new float[16];
private float[] inclinationMatrix = new float[16];
private PlatformCallback<float[]> callback;
public MotionSensor(Activity activity) {
this.activity = activity;
}
#Override
public void onSensorChanged(SensorEvent event) {
switch (event.sensor.getType()) {
case Sensor.TYPE_ACCELEROMETER:
gravity = event.values.clone();
break;
case Sensor.TYPE_MAGNETIC_FIELD:
geomag = event.values.clone();
break;
}
if (gravity != null && geomag != null) {
boolean success = SensorManager.getRotationMatrix(rotationMatrix,
inclinationMatrix, gravity, geomag);
if (success) {
notifyCallback(new Result(), rotationMatrix);
}
}
}
#Override
public void onAccuracyChanged(Sensor sensor, int i) {
}
private void notifyCallback(Result result, float[] rotationMatrix) {
callback.callback(result, rotationMatrix);
}
public void start(PlatformCallback<float[]> callback) {
this.callback = callback;
sensorManager = (SensorManager) activity.getSystemService(Activity.SENSOR_SERVICE);
if (sensorManager != null) {
boolean accelerometerSupport = sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),
SensorManager.SENSOR_DELAY_UI);
boolean magneticFieldSupport = sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD),
SensorManager.SENSOR_DELAY_UI);
if (!accelerometerSupport || !magneticFieldSupport) {
sensorManager.unregisterListener(this);
notifyCallback(new Result(Result.STATE.FAILED, "Not supported"), null);
}
} else {
notifyCallback(new Result(Result.STATE.FAILED, "Not supported"), null);
}
}
public void stop() {
if (sensorManager != null) {
sensorManager.unregisterListener(this);
}
}
}
And the PlaformCallback class:
public abstract class PlatformCallback<T> {
public void callback(final Result result, final T t) {
Gdx.app.postRunnable(new Runnable() {
#Override
public void run() {
doCallback(result, t);
}
});
}
protected abstract void doCallback(Result result, T t);
}
In the core project you can now simply turn on and off your motion sensors:
private void startMotionSensor() {
platform.startMotionSensors(new PlatformCallback<float[]>() {
#Override
protected void doCallback(Result result, float[] rotationMatrix) {
if (result.ok()) {
// Do what you want with the rotation matrix
}
}
});
}
public void stopMotionSensor() {
platform.stopMotionSensors();
}

I have a location tracking app. I have a Foreground service that when the app goes into the background, it continues to get the location. That part works fine. If I output the location I can see the different points and correct timestamps.
While in the background I need to POST that data to an API endpoint. My GPSHeartbeat class is a singleton and it exposes a function to let me update the Singletons location property.
While in the foreground, everything works fine. When in the background, the location IS updated, but the singleton has the last location from BEFORE it went into the background.
My APICommunicator is firing in the background on its interval like it should, it just doesn't have the correct Location.
Here is the broadcast receiver that is responsible for listening to the Foreground services location change.
This works fine in the background and in the foreground. It is successfully getting the updated location.
private void onNewLocation(Location location)
{
Log.i(TAG, "onNewLocationRec'd: " + location);
mLocation = location;
// Notify anyone listening for broadcasts about the new location.
Intent intent = new Intent(ACTION_BROADCAST);
intent.putExtra(EXTRA_LOCATION, location);
LocalBroadcastManager.getInstance(getApplicationContext()).sendBroadcast(intent);
// Update notification content if running as a foreground service.
if (serviceIsRunningInForeground(this)) {
mNotificationManager.notify(NOTIFICATION_ID, getNotification());
}
}
The BroadcastReceiver is an inner class of an Activity called HomeActivity. This gets the CORRECT location from the service. If I output the log, it is the same as what the Service broadcast.
public class HomeActivity extends AppCompatActivity
{
private GPSHeartbeat mGPSHeartbeat;
private GPSReceiver myReceiver;
private LocationUpdatesService mService = null;
private boolean mBound = false;
private final ServiceConnection mServiceConnection = new ServiceConnection()
{
#Override
public void onServiceConnected(ComponentName name, IBinder service)
{
LocationUpdatesService.LocalBinder binder = (LocationUpdatesService.LocalBinder) service;
mService = binder.getService();
mBound = true;
}
#Override
public void onServiceDisconnected(ComponentName name)
{
mService = null;
mBound = false;
}
};
private void GPSBeginRequestingUpdates()
{
//Wait 5 seconds to spin up
(new Handler()).postDelayed(this::StartGPSUpdates, 5000);
}
private void StartGPSUpdates()
{
mService.requestLocationUpdates();
}
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
myReceiver = new GPSReceiver();
setContentView(R.layout.activity_home);
mGPSHeartbeat = GPSHeartbeat.instance(getApplicationContext()).setInterval(6);
}
#Override
protected void onStart()
{
super.onStart();
bindService(new Intent(getApplicationContext(), LocationUpdatesService.class), mServiceConnection, Context.BIND_AUTO_CREATE);
}
#Override
protected void onStop()
{
if (mBound) {
unbindService(mServiceConnection);
mBound = false;
}
super.onStop();
}
#Override
protected void onResume()
{
super.onResume();
LocalBroadcastManager.getInstance(getApplicationContext()).registerReceiver(myReceiver, new IntentFilter(LocationUpdatesService.ACTION_BROADCAST));
GPSBeginRequestingUpdates();
}
#Override
protected void onPause()
{
LocalBroadcastManager.getInstance(getApplicationContext()).unregisterReceiver(myReceiver);
super.onPause();
}
private class GPSReceiver extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{

if (location != null) {
Log.i(TAG, "\nonReceived New Location: " + GPSUtils.getLocationText(location));
GPSHeartbeat.instance(context.getApplicationContext()).SetLocation(location);
}
}
}
}
The Singleton. The SetLocation() does receive the correct location. It is only during my POST request that the APICommunicator is using the GPSHeartbeat's old location. Even though it was just updated.
How do I make sure I update to the correct location?

In the Manifest:

android:enabled="true"
android:exported="true"
android:foregroundServiceType="location" />
Actually I don't see that you are using foreground service. Not foreground service would be killed very soon after the application goes background. Plus communication with API should be in the scope of foreground service because activity could be killed by the system.
Im creating an app in android studio where I want 10 clips to be played at the same time side by side. Im having some problems with some lags already at three clips and I wounder if Im better off using threads? In that case how?
Any hint would be very much apreciated
Here is my code so far. I know it is not very efficient and I am better off using an array of a player object for example but Im just testing so far:
public class MainActivity extends AppCompatActivity implements TextureView.SurfaceTextureListener {
private MediaPlayer mp1, mp2, mp3;
private TextureView tv1, tv2, tv3;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv1 = findViewById(R.id.textureView1);
tv2 = findViewById(R.id.textureView2);
tv3 = findViewById(R.id.textureView3);
tv1.setSurfaceTextureListener(this);
tv2.setSurfaceTextureListener(this);
tv3.setSurfaceTextureListener(this);
}
#Override
public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height) {
Surface surface = new Surface(surfaceTexture);
mp1 = MediaPlayer.create(this, R.raw.a7);
mp1.setSurface(surface);
// mp1.prepareAsync(); //
mp1.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp1) {
mp1.start();
}
});
Surface surface2 = new Surface(surfaceTexture);
mp2 = MediaPlayer.create(this, R.raw.a9);
mp2.setSurface(surface2);
// mp1.prepareAsync(); //
mp2.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp2) {
mp2.start();
}
});
Surface surface3 = new Surface(surfaceTexture);
mp3 = MediaPlayer.create(this, R.raw.a10);
mp3.setSurface(surface3);
// mp1.prepareAsync(); //
mp3.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp3) {
mp3.start();
}
});
}
#Override
public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {
}
#Override
public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {
return false;
}
#Override
public void onSurfaceTextureUpdated(SurfaceTexture surface) {
}
#Override
protected void onPause() {
if (mp1 != null && mp1.isPlaying()) {
mp1.pause();
}
super.onPause();
}
#Override
protected void onResume() {
if (mp1 != null) {
mp1.start();
}
super.onResume();
}
#Override

if (mp1 != null) {
mp1.stop();
mp1.release();
mp1 = null;
}
super.onDestroy();
}
}
You should play media in a different non-ui thread. like this:-
public class MediaService extends Service {
private MediaPlayer mp1, mp2, mp3;
private static final String ACTION_START = TAG + ".ACTION_START";
private IBinder mBinder = new MyBinder();
private MediaPlayer.OnPreparedListener mMediaPrepared = new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
Log.d(TAG, "MediaPlayer.onPrepared");
onCommandPlay(mp);
}
};
#Override
public IBinder onBind(Intent intent) {
Log.v(TAG, "onBind");
return mBinder;
}
#Override
public void onCreate() {
super.onCreate();
m1 = MediaPlayer.create(this, R.raw.a1);
m2 = MediaPlayer.create(this, R.raw.a2);
m3 = MediaPlayer.create(this, R.raw.a9);
}
#Override
public void onDestroy() {
super.onDestroy();
if (m1 != null) m1 .release();
if (m2 != null) m2 .release();
if (m3 != null) m3 .release();
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
final String action = intent.getAction();
Log.d(TAG, "onStartCommand: " + intent.getAction());
if (ACTION_START.equals(action)) {
onCommandStart();
return START_STICKY;
}
stopSelf();
return Service.START_STICKY_COMPATIBILITY;
}
/**

*
*/
private void onCommandStart() {
// Create Notifications with remote views
mNotification = new NotificationCompat.Builder(this).setTicker("Media Service started...")
.setSmallIcon(R.mipmap.ic_launcher)
.setContent(collapsed)
.setAutoCancel(false)
.setOngoing(true)
.build();
startForeground(NOTIFICATION_ID, mNotification);
startPlaying();
}
private void onCommandPlay(MediaPlayer mp) {
try {
mp.start();
} catch (IllegalStateException e) {
Log.e(TAG, "onCommandPlay", e);
}
}
/**

*
*/
private void startPlaying() {
mCurrent = item;
try {
mp1.reset();
mp1.setOnPreparedListener(mMediaPrepared);
mp2.reset();
mp2.setOnPreparedListener(mMediaPrepared);
mp3.reset();
mp3.setOnPreparedListener(mMediaPrepared);
AssetFileDescriptor afd1 = getResources().openRawResourceFd(getResources().openRawResourceFd(R.raw.a9););
AssetFileDescriptor afd2 = getResources().openRawResourceFd(getResources().openRawResourceFd(R.raw.a10););
AssetFileDescriptor afd3 = getResources().openRawResourceFd(getResources().openRawResourceFd(R.raw.a8););
mp1.setDataSource(afd1 .getFileDescriptor(), afd1 .getStartOffset(), afd1.getLength());
mp2.setDataSource(afd2 .getFileDescriptor(), afd2 .getStartOffset(), afd2 .getLength());
mp3.setDataSource(afd3 .getFileDescriptor(), afd3 .getStartOffset(), afd3 .getLength());
mp1.prepareAsync();
mp2.prepareAsync();
mp3.prepareAsync();
} catch (IOException e) {
Log.e(TAG, "startPlaying", e);
}
}
public class MyBinder extends Binder {
public MediaService getService() {
return MediaService.this;
}
}
}
then start the service from Activity like this:
Intent intent = new Intent(context, MediaService.class);
intent.setAction(ACTION_START);
startServie(intent);
You should also handle different media playing use-cases. You can refer this link for more.
I use this code to play the full-screen video but I have a problem when it is video playing and moving from the main activity to the full-screen activity occurs freezing of the video for 2-3 seconds This problem occurs only with the releases after 2.8.3 only but with 2.8.0 works Video is smooth

Just try out this code for video freeze problem:
#Override
public void play() {
player.setPlayWhenReady(true);
player.getPlaybackState();
}
#Override
public void pause() {
player.setPlayWhenReady(false);
player.getPlaybackState();
}
Here player.getPlaybackState(); is help full to get it to back state.

Your code looks pretty good. There are few things those might be causing problems. please check those.
First of all make sure compiler is going inside the "OnLocationChanged()" method.
Second thing make sure your web-service call method is of "Update" type. Because you are using "Update". It can be "Post".
Third thing is print the response in "OnFailure()" method, maybe it is going to failure.
I hope you will find the problem by checking these scenarios.
I'm trying play an audio file with the mediacontroler in my android application. When playing audio the seekbar does not move.I looked mediacontroler function. But I could not find a function for updating seekbar.
please advice.

You can update the seekbar yourself, e.g.:
final Handler mHandler = new Handler();
final Runnable mUpdateSeekbar = new Runnable() {
public void run() {
mSeekBar.setProgress(mMediaPlayer.getCurrentPosition());
mSeekBar.setMax(mMediaPlayer.getDuration());
mHandler.postDelayed(this, 1000);
}
};
Post the runnable in onResume and mHandler.removeCallbacks(mUpdateSeekbar) in onPause.
