Exoplayer playing audio even when the PlayerView has been paused

I'm creating an Exoplayer video player which plays a mp4 file containing video and audio from a url. The video and audio plays properly but when the video player is paused, the audio is still being played. I don't know how I can fix this. I'm assuming that the problem occurs due to my android device. I'm leaving my code, app's info, android device info below and a video clip of my problem. If someone can use my code and tell me if they are experiencing the same problem, it will be thankful. Please Help Me.
The app's detail:
Using API 21: Android 5.0 (Lollipop). Contains Internet Permission. Importing implementation 'com.google.android.exoplayer:exoplayer:2.8.1'.

Video Clip of the problem (The video has been uploaded on OpenLoad server):

I made a very easy sample app to reproduce the issue
but yet too see any problem neither with the player or video
here is the code:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

SimpleExoPlayer player = ExoPlayerFactory.newSimpleInstance(this, new DefaultTrackSelector(new DefaultBandwidthMeter.Builder().build()));
SimpleCache downloadCache = new SimpleCache(new File(getCacheDir(), "exoCache"), new NoOpCacheEvictor());
String uri = "http://dash.akamaized.net/akamai/bbb/bbb_1280x720_60fps_6000k.mp4";
DataSource.Factory dataSourceFactory = new CacheDataSourceFactory(downloadCache, new DefaultDataSourceFactory(this, "seyed"));
MediaSource mediaSource = new ExtractorMediaSource.Factory(dataSourceFactory).createMediaSource(Uri.parse(uri));
player.addListener(new Player.EventListener() {
#Override

Update 17/18/2018
Actually the problem you are facing is because of this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); line.
when you run your activity it starts in portrait mode and everything is fine (without this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);) and one exoplayer is created and starts the playback.
but when you change the orientation during startup of the activity. android trys to destroy the activity and create another one here comes your problem:
first activity does not get destroyed because you forget to realease the ExoPlayer in onDestroy() and when the new activity is created a new exoplayer is also created and both of them keep the playback going. when you pause the playback you actually pausing the second one not the first one. this behavior is called memory leak.
first of all make sure you call .release() in onDestroy() of the activity.
and then for orientation you have couple of options:
1.specify the orientation of the activity in the manifest so android apply it before the creation of the activity
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar"
android:screenOrientation="sensorLandscape">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
2.prevent android from killing the activity on config changes:
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar"
android:configChanges="orientation">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
hope it helps you
you can also chek out this sample (with a small and minor difference) on github:

How can I turn on and off mobile data using toggle button?

Today I have done a task using toggle button. The mobile data needs to be turned on when I press the enable toggle button, and it should be turned off when I press the same button. I had done everything and when I press the enable button, the mobile data remains off. In fact I have added all the manifest permissions. The mobile data should turn on when I press the toggle button. Please help me friends,and also let me know where I committed mistake. I hereby enclosed my XML and Java coding. Please help me friends, Many thanks in advance.

You can access mobile data on / off programmaticaly below android 4.4 but not above 4.4 as It's require MODIFY_PHONE_STATE permission check. This permission is only given to system or signature apps. so It wont work on non-rooted phone.

Android camera preview stay white, but no crash

I'm trying to create an application with the camera on Android. I used code I was able to found in the android doc, on internet etc. just as test.
The camera preview is still white, nothing crashes tho but no preview at all is showing up. Can't find if it comes from my emulator or my code ... I use integrated Webcam as camera in the emulator.
Any help please ?
here is my camera preview class:

super(context);
mCamera = camera;
// Install a SurfaceHolder.Callback so we get notified when the
// underlying surface is created and destroyed.
mHolder = getHolder();
mHolder.addCallback(this);
// deprecated setting, but required on Android versions prior to 3.0
mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
public void surfaceCreated(SurfaceHolder holder) {
// The Surface has been created, now tell the camera where to draw the preview.
try {
mCamera.setPreviewDisplay(holder);
mCamera.startPreview();
} catch (IOException e) {
System.out.println("Error setting camera preview: " + e.getMessage());
}
}
public void surfaceDestroyed(SurfaceHolder holder) {
// empty. Take care of releasing the Camera preview in your activity.
}
public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
// If your preview can change or rotate, take care of those events here.
// Make sure to stop the preview before resizing or reformatting it.
if (mHolder.getSurface() == null){
// preview surface does not exist
return;
}
// stop preview before making changes
try {
mCamera.stopPreview();
} catch (Exception e){
// ignore: tried to stop a non-existent preview
}
// set preview size and make any resize, rotate or
// reformatting changes here
// start preview with new settings

Android - Admob test ads not appearing in app

I want to integrate Google Mobile Ads into my app, but when I debug it, whenever using my own device, or using an emulator, no ads appear.
I am using the code from Google's developer page: https://developers.google.com/mobile-ads-sdk/docs/admob/fundamentals
When looking at logcat, I find that my app is not requesting any ads, and Admob is reporting no requests.
What am I missing?

I have seen something strange in your code:
In your AdBanner.java you use this:
import com.google.android.gms.ads.AdView;
but in your layout you use:
<com.google.ads.AdView
which corresponds to old Admob, but seems you may want to use com.google.android.gms.ads.AdView in your layout instead

I think you must check the android logs to see if any errors or warnings are given for your admob. For example: I was not able to see the ads too and when i check the logs i found the "not enough space" warning for my advertisement. I was using the size "SMART_BANNER" that uses the width as 360dp (you can check the sizes here). So i changed my AdView's width to exact 360dp to solve my problem and it is now working: Stil
I hope this information helps. Just check the logs and also console.
In addition, my adView:
<com.google.android.gms.ads.AdView
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:id="#+id/adView"
android:layout_width="360dp"
android:layout_height="wrap_content"
ads:adSize="SMART_BANNER"
ads:adUnitId="#string/banner_ad_unit_id" />
Best regards.

Admob + surfaceview don't play well

I'm running Admob 6.0.1 and trying to add the advert over the top of the surface view, I can say that the code below works great with a Android 3.2 (a real device), and also works fine with a android 4 device in the emulator but, when I try to test on pre api13, eg 2.3.3 or below the advert doesn't show. Now here's the weird part, if I change the visibility of the surfaceview (in xml) to invisible the advert will show!!!! what's going on?? Is this just the emulator being buggy or do I have a real problem?
I've tried to keep the code as simple as possible to reproduce the error. I've added a button just to show the surfaceview does allow other views to update, just not the Admob view...
package com.google.example.ads.fundamentals;
import android.app.Activity;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.os.Bundle;
import android.util.AttributeSet;
import android.util.Log;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import com.google.ads.AdView;
public class BannerSample extends Activity {
/** The view to show the ad. */
private AdView adView;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout);
adView = (AdView) findViewById(R.id.adView);
}
/** Called before the activity is destroyed. */
#Override
public void onDestroy() {
// Destroy the AdView.
if (adView != null) {
adView.destroy();
}
super.onDestroy();
}
}
class Panel extends SurfaceView implements SurfaceHolder.Callback {
private final TutorialThread _thread;
public Panel(Context context, AttributeSet att) {
super(context, att);
getHolder().addCallback(this);
_thread = new TutorialThread(getHolder(), this);
}
#Override
public void onDraw(Canvas canvas) {
canvas.drawColor(Color.BLUE);
Log.d("Hello", "drawing stuff");
}
#Override
public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
Log.d("HELLO", "surface changed" + holder.getSurfaceFrame().width()
+ "Height: " + holder.getSurfaceFrame().height());
}
#Override
public void surfaceCreated(SurfaceHolder holder) {
_thread.setRunning(true);
_thread.start();
}
#Override
public void surfaceDestroyed(SurfaceHolder holder) {
// simply copied from sample application LunarLander:
// we have to tell thread to shut down & wait for it to finish, or
// else
// it might touch the Surface after we return and explode
boolean retry = true;
_thread.setRunning(false);
while (retry) {
try {
_thread.join();
retry = false;
} catch (InterruptedException e) {
// we will try it again and again...
}
}
}
}
class TutorialThread extends Thread {
private final SurfaceHolder _surfaceHolder;
private final Panel _panel;
private boolean _run = false;
public TutorialThread(SurfaceHolder surfaceHolder, Panel panel) {
_surfaceHolder = surfaceHolder;
_panel = panel;
}
public void setRunning(boolean run) {
_run = run;
}
#Override
public void run() {
Canvas c;
while (_run) {
c = null;
try {
c = _surfaceHolder.lockCanvas(null);
synchronized (_surfaceHolder) {
_panel.onDraw(c);
}
} finally {
// do this in a finally so that if an exception is thrown
// during the above, we don't leave the Surface in an
// inconsistent state
if (c != null) {
_surfaceHolder.unlockCanvasAndPost(c);
}
}
}
}
}
and the XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

<Button android:id="#+id/mybutton" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_below="#id/adView"
android:text="hello" />
</RelativeLayout>
And the manifest:

Any ideas or help would be so great, I've tried to post on Google Groups for admob but I think it got lost in a void..

As it turns out it was a problem with the emulator, When the code was run on a real device it worked fine! crazy emulator...

Try placing the AdView outside of the SurfaceView instead of on top of it. You can do this by aligning the AdView ad the top, and setting the SurfaceView below it.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:layout_width="match_parent" android:layout_height="match_parent">
<com.google.example.ads.fundamentals.Panel
android:id="#+id/mainPanel" android:layout_width="match_parent"
android:layout_height="match_parent" android:visibility="invisible"
android:layout_below="#+id/adView" />
<com.google.ads.AdView android:id="#id/adView"
android:layout_width="match_parent" android:layout_height="wrap_content"
android:layout_gravity="top" ads:adSize="BANNER" ads:adUnitId="xxxxxxxxx"
ads:loadAdOnCreate="true" ads:testDevices="TEST_EMULATOR"
android:layout_alignParentTop="true" />
</RelativeLayout>
