I'm trying to make an auto click app with AccessibilityService. I use method dispatchGesture with a AccessibilityService.GestureResultCallback to perform click on the screen and repeat it in onCompleted(). The problem is if I touch the screen before gesture completed, the gesture cancelled (onCancelled fired). How could I prevent screen touch stop my gesture?

How could I prevent screen touch stop my gesture?
You can't do that by dispatchGesture. From the official documentation about dispatchGesture: Dispatch a gesture to the touch screen. Any gestures currently in progress, whether from the user, this service, or another service, will be cancelled. Thus, gestures dispatched by your service can be canceled by user.
I have an earphone, headset. It, vertically, has the buttons, increase volume, middle button, lower volume.
By pressing the middle button, it opens the spotify and plays music, even with the screen off or the phone locked.
I would like to do this for an application of mine, when press this middle button, this application trigger an event, is it possible? Or, press one of the volume buttons and trigger an event.
It is possible? If yes, is there any example, source code, with this application?
EDIT:
The code did not work:
Main:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
IntentFilter filtro = new IntentFilter(Intent.ACTION_MEDIA_BUTTON);//"android.intent.action.MEDIA_BUTTON"
MediaButtonIntentReceiver r = new MediaButtonIntentReceiver();
filtro.setPriority(1000); //this line sets receiver priority
registerReceiver(r, filtro);
}
}
Broadcast:
public class MediaButtonIntentReceiver extends BroadcastReceiver {
public MediaButtonIntentReceiver() {
super();
}
#Override
public void onReceive(Context context, Intent intent) {
String intentAction = intent.getAction();
if (!Intent.ACTION_MEDIA_BUTTON.equals(intentAction)) {
return;
}
KeyEvent event = (KeyEvent) intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
if (event == null) {
return;
}
int action = event.getAction();
if (action == KeyEvent.ACTION_DOWN) {
toDo();
Toast.makeText(context, "BUTTON PRESSED!", Toast.LENGTH_SHORT).show();
}
abortBroadcast();
}
Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.aula.bob.headset">
<application
android:allowBackup="true"

Create a class extending Broadcast Receiver in your App:
public class MediaButtonIntentReceiver extends BroadcastReceiver {
public MediaButtonIntentReceiver() {
super();
}
#Override
public void onReceive(Context context, Intent intent) {
String intentAction = intent.getAction();
if (!Intent.ACTION_MEDIA_BUTTON.equals(intentAction)) {
return;
}
KeyEvent event = (KeyEvent)intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
if (event == null) {
return;
}
int action = event.getAction();
if (action == KeyEvent.ACTION_DOWN) {
// do something
Toast.makeText(context, "BUTTON PRESSED!", Toast.LENGTH_SHORT).show();
}
abortBroadcast();
}
}
And in your Activity Class:
public class MainActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
IntentFilter filter = new IntentFilter(Intent.ACTION_MEDIA_BUTTON);//"android.intent.action.MEDIA_BUTTON"
MediaButtonIntentReceiver r = new MediaButtonIntentReceiver();
filter.setPriority(10000); //this line sets receiver priority
registerReceiver(r, filter);
}
}
Define your Receiver in Android Manifest like this:
<receiver android:name=".MediaButtonIntentReceiver">
<intent-filter>
<action android:name="android.intent.action.MEDIA_BUTTON" />
</intent-filter>
</receiver>
Hope it will work for you!
My service class is not calling and there is no error, crash report or exception!The line before and after calling the service is working and i have also checked using isMyServiceRunning method and its not working..
public class MainActivity extends AppCompatActivity {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent i = new Intent(this, MyService.class);
startService(i);
Toast.makeText(this,"to check if this is working",Toast.LENGTH_LONG).show();
}
}
Service class :
public class MyService extends Service implements SensorEventListener {
private SensorManager mSensorManager;
private Sensor mSensor;
double ax, ay, az;
#Override
public void onCreate() {
super.onCreate();
mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
mSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
if (mSensor != null) {
mSensorManager.registerListener(this, mSensor, SensorManager.SENSOR_DELAY_NORMAL);
} else {
stopSelf();
}
}

Please, help!
do this
<service

android:exported="true">
</service>
Try to set attribute android:enabled of service's declaration to true in manifest.xml, otherwise service can not be instantiated.

I can listen volume level in my VolumeService. This service listen to volume level in background.
My problem is: I can't control volume in lock screen.
I tried two different ways for volume control
First Way with CCL
Application Class:
public class CastApplication extends Application {
private static String APPLICATION_ID;
public static final double VOLUME_INCREMENT = 0.03;
#Override
public void onCreate() {
super.onCreate();
APPLICATION_ID = getString(R.string.app_id);
// initialize VideoCastManager
VideoCastManager.initialize(this, APPLICATION_ID, VideoCastControllerActivity.class, null).
setVolumeStep(VOLUME_INCREMENT).enableFeatures(VideoCastManager.FEATURE_NOTIFICATION |VideoCastManager.FEATURE_LOCKSCREEN |
VideoCastManager.FEATURE_WIFI_RECONNECT | VideoCastManager.FEATURE_CAPTIONS_PREFERENCE |VideoCastManager.FEATURE_DEBUGGING);
}
}
MainActivity:
public class MainActivity extends FragmentActivity {
private VideoCastManager mCastManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
VideoCastManager.checkGooglePlayServices(this);
mCastManager = VideoCastManager.getInstance();
Intent i1 = new Intent(this,VolumeService.class);
startService(i1);
}
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
if (mCastManager.onDispatchVolumeKeyEvent(event, CastApplication.VOLUME_INCREMENT)) {
return true;
}
return super.dispatchKeyEvent(event);
}
}
Second way without CCL (with RRC)
MainActivity:
public class MainActivity extends FragmentActivity {
ContentObserver mSettingsContentObserver;
RemoteControlClient remoteControlClient;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new Intent(Intent.ACTION_MEDIA_BUTTON);
AudioManager mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
mAudioManager.requestAudioFocus(null, AudioManager.STREAM_RING,AudioManager.AUDIOFOCUS_GAIN_TRANSIENT_MAY_DUCK);
RemoteControlClientCompat mRemoteControlClientCompat = new RemoteControlClientCompat(PendingIntent.getBroadcast(this.getApplicationContext(), 0,intent, 0));
RemoteControlHelper.registerRemoteControlClient(mAudioManager,mRemoteControlClientCompat);
remoteControlClient = new RemoteControlClient((PendingIntent.getBroadcast(this.getApplicationContext(), 0,intent, 0)));
MediaRouter.getInstance(this.getApplicationContext()).addRemoteControlClient(remoteControlClient);
Intent i1 = new Intent(this,VolumeService.class);
startService(i1);
}
}
Service and ContentObserver are same for both way
VolumeService:
public class VolumeService extends Service {
ContentObserver mSettingsContentObserver;
#Override
public void onCreate() {
super.onCreate();
mSettingsContentObserver = new SettingsContentObserver(this, new Handler());
getApplicationContext().getContentResolver().registerContentObserver(
android.provider.Settings.System.CONTENT_URI, true,mSettingsContentObserver);
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onDestroy() {
super.onDestroy();
getApplicationContext().getContentResolver().unregisterContentObserver(mSettingsContentObserver);
}
}
ContentObserver:
public class SettingsContentObserver extends ContentObserver {
int previousVolume;
Context context;
public SettingsContentObserver(Context c, Handler handler) {
super(handler);
context = c;
AudioManager mAudioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
previousVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_RING);
}
#Override
public boolean deliverSelfNotifications() {
return super.deliverSelfNotifications();
}
#Override
public void onChange(boolean selfChange) {
super.onChange(selfChange);
AudioManager audio = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
int currentVolume = audio.getStreamVolume(AudioManager.STREAM_RING);
int delta = previousVolume - currentVolume;
if (delta > 0) {
Log.i("MyService", "Volume is down");
previousVolume = currentVolume;
} else if (delta < 0) {
Log.i("MyService", "Volume is up");
previousVolume = currentVolume;
}
}
}

i have problem with sending Broadcast receive from one activity to other ..its not working my code is below..pls refer to it ..
sending class is:

setContentView(R.layout.main);
Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
sendBroadcast();
}
});
}
public void sendBroadcast(){
Intent broadcast = new Intent();
broadcast.setAction("com.unitedcoders.android.broadcasttest.SHOWTOAST");
sendBroadcast(broadcast);
}
}
and reciving class is :
