Not able to Launch an App on Boot in Android TV

I want to automatically launch my app on TV startup. i.e. when the user power on the TV, TV will powerup and my app will start.
I have followed multiple links on internet and tried to implement it but no activity is shown on startup.
Followed
How to start/ launch application at boot time Android
As I was not getting any response on start, followed Android-Boot Completed is not working in Broadcastreceiver
I have extensively searched web and stackoverflow, it is strange that I cannot find a solution to make it work till now. Don't know what am I doing wrong...
here is my code...
MainActivity.java
public class MainActivity extends FragmentActivity {
public WebView mWebview;
private android.content.Context Context;
private ProgressDialog mProgressDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
String url = "http://www.test.com";
if (!DetectConnection.checkInternetConnection(this)) {
Toast.makeText(getApplicationContext(), "No Internet Connection!", Toast.LENGTH_LONG).show();
finish(); //Calling this method to close this activity when internet is not available.
} else {
WebView webView = (WebView) findViewById(R.id.main_fragment);
webView.getSettings().setJavaScriptEnabled(true);
CookieManager.getInstance().setAcceptCookie(true);
webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
WebSettings webSettings = webView.getSettings();
webSettings.setDomStorageEnabled(true);
webSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);
webSettings.setUseWideViewPort(true);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl(url);
}
}

The broadcast receiver is not called with changing the date only on PIE

I'm currently working on a simple android app. The idea is, it changes the wallpaper automatically after 12 A.M or when the date is changed. It's working on android Oreo and lower versions, however, it doesn't work on android 9(Pie). However, if I change the date manually from the setting of the phone, it calls the broadcast. I have googled a lot, and some suggested to register the broadcast on your java codes instead of Manifest. Unfortunately, it didn't work.
I have tested this question in Stackoverflow.
First of all, changing the date is not part of implicit broadcasts, secondly, I assumed it is. then I changed the codes but it didn't work.
Now I'm gonna provide some codes of my broadcast:
DailyBroadcastReceiverService
public class DailyBroadcastReceiverService extends Service {
private BroadcastReceiver dailyZekrBr;
private Context context;
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
registerDailyZekrReceiver();
}
#Override
public void onDestroy() {
super.onDestroy();
unregisterReceiver(dailyZekrBr);
dailyZekrBr = null;
}
private void registerDailyZekrReceiver() {
context= this.getApplicationContext();
Log.d("Register", "onStart: Now gonna register the broadcast receiver on Daily Boadcast receiver");
dailyZekrBr = new DailyZekrBroadcastReceiver();
IntentFilter filter = new IntentFilter();
filter.addCategory(Intent.CATEGORY_DEFAULT);
filter.addAction("android.intent.action.ACTION_TIME_CHANGED");
filter.addAction("android.intent.action.TIME_SET");
filter.addAction("android.intent.action.DATE_CHANGED");
filter.addAction("android.intent.action.TIMEZONE_CHANGED");
this.registerReceiver(dailyZekrBr, filter);
}
}
DailyZekrBroadcastReceiver
public class DailyZekrBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d("DailyZekrBroadcast", "onReceive:The broadcast is called ");
DailyZekrHandler.setTodayImage(context);
}
}
setTodayImage
public static void setTodayImage(Context context) {
int todayImage = DailyZekrHandler.nameOfTheWeek();
DisplayMetrics metrics = new DisplayMetrics();
WindowManager window = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
window.getDefaultDisplay().getMetrics(metrics);
Log.d("DailyZekrBroadCast", "trying to change imge: " + todayImage);
if(todayImage != DailyZekrHandler.getTodayImage(context)) {
DailyZekrHandler.storeTodayImage(context);
Bitmap tempbitMap = BitmapFactory.decodeResource(context.getResources(), todayImage);
Bitmap bitmap = Bitmap.createScaledBitmap(tempbitMap, metrics.widthPixels, metrics.heightPixels, true);
WallpaperManager wallpaperManager = WallpaperManager.getInstance(context);
wallpaperManager.setWallpaperOffsetSteps(1, 1);
wallpaperManager.suggestDesiredDimensions(metrics.widthPixels, metrics.heightPixels);
try {
wallpaperManager.setBitmap(bitmap);
Log.d("DailyZekrBroadCast", "today_image: " + todayImage);
} catch (IOException e) {
e.printStackTrace();
}

i have problem with admob. Admob is working good but when i exit my game admob is still working. What i done wrong ? Please help me.
Even if i exit the game, in the logcat i see that admob is still working.
AndroidLuncher.java

02-13 14:59:56.931: I/Ads(2604): Ad finished loading.

Create an onStop() method and stop adMob there as well.

Try setting the AdView instance to NULL and leave it there for the GC to handle it. It probably will trow a NullPointerException so make sure you handle that.

I solved the problem.
I had two times Adview adview;
public class AndroidLauncher extends AndroidApplication {
private AdView adView;
#Override
protected void onCreate (Bundle savedInstanceState) {
***
// Create and setup the AdMob view
AdView adView = new AdView(this);
***
When I removed one, AdMob is working correctly.

admob is not show in my SDL game

i have wrote SDL game and ported it to andorid
and now I tried to integrate it with admob but i failed

mLayout.addView(mSurface);
setContentView(mLayout); #########// if i comment this i can see the ad but the game is not show!
}

// If Ads are loaded, show Interstitial else show nothing.
if (interstitial.isLoaded()) {

interstitial.show();
}
}
if i comment this line i can see the ad but not the game ! :
setContentView(mLayout);
So how i can show the ad from starting my game until it exit ?

Problem with MainActivity.It works with ActionBar Tabs + Fragments (code below). In other Activities all work fine.
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.activity_main);
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_header);
final ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
String label1 = getResources().getString(R.string.label1);
Tab tab = actionBar.newTab();
tab.setText(label1);
TabListener<Login> tl = new TabListener<Login>(this, label1, Login.class);
tab.setTabListener(tl);
actionBar.addTab(tab);
String label2 = getResources().getString(R.string.label2);
tab = actionBar.newTab();
tab.setText(label2);
TabListener<Registration> tl2 = new TabListener<Registration>(this, label2, Registration.class);
tab.setTabListener(tl2);
actionBar.addTab(tab);
}
private class TabListener<T extends Fragment> implements ActionBar.TabListener {
private Fragment mFragment;
private final Activity mActivity;
private final String mTag;
private final Class<T> mClass;
public TabListener(Activity activity, String tag, Class<T> clz) {
mActivity = activity;
mTag = tag;
mClass = clz;
}
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// Check if the fragment is already initialized
if (mFragment == null) {
// If not, instantiate and add it to the activity
mFragment = Fragment.instantiate(mActivity, mClass.getName());
ft.add(android.R.id.content, mFragment, mTag);
} else {
// If it exists, simply attach it in order to show it
ft.attach(mFragment);
}
}
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
if (mFragment != null) {
// Detach the fragment, because another one is being attached
ft.detach(mFragment);
}
}
public void onTabReselected(Tab tab, FragmentTransaction ft) {
// User selected the already selected tab. Usually do nothing.
}
}
}
}

If you want to use ActionBar you need to request for the ActionBar
See the code below.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// The Action Bar is a window feature. The feature must be requested
// before setting a content view.
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
setContentView(R.layout.main);
// experiment with the ActionBar
ActionBar actionBar = getActionBar();
actionBar.hide();
}

getActionBar() was introduced in API level 11. In your manifest, you claim your app will run on API level 8 as well. It won't.
Here are numerous reasons why the call may return null on a device with API >= 11.

I had similiar problem, i used to get error on the lines below, since
I was requesting the custom title feature before setting the content view.
setContentView(R.layout.userlayout);
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE)
first request the feature and problem went away
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE)
setContentView(R.layout.userlayout);
Hope that is the solution you wanted..
