How do I check if the download completed in onCreate android fetch library?

How do I check if the download completed in onCreate fetch library?
The following code work without problem, but maybe user cancel the download operation before completion and incomplete file exists in the path.
public class MainActivity extends AppCompatActivity implements FetchObserver<Download> {
private Button Edame, tavaghof, DownloadImage, online;
public static TextView etaTextView;

}
} catch (Exception e) {

}
private void updateViews(#NotNull Download download, Reason reason) {
if (request.getId() == download.getId()) {
if (reason == Reason.DOWNLOAD_COMPLETED) {
dllaye.setVisibility(View.GONE);
Toast.makeText(getApplicationContext(), "File download successful",
Toast.LENGTH_LONG).show();
}
setProgressView(download.getStatus(), download.getProgress());
etaTextView.setText(Utils.getETAString(this, download.getEtaInMilliSeconds()));
downloadSpeedTextView.setText(Utils.getDownloadSpeedString(this, download.getDownloadedBytesPerSecond()));
}
}
private void setProgressView(#NonNull final Status status, final int progress) {
switch (status) {
case QUEUED: {
progressTextView.setText(R.string.queued);
progressBar.setProgress(progress);
break;
}
case ADDED: {
progressTextView.setText(R.string.added);
progressBar.setProgress(progress);
break;
}
case DOWNLOADING: {
if (progress == -1) {
progressTextView.setText(R.string.downloading);
progressBar.setProgress(progress);
} else {
final String progressString = getResources().getString(R.string.percent_progress, progress);
progressTextView.setText(progressString);
progressBar.setProgress(progress);
}
break;
}
case COMPLETED: {
break;
}
default: {
progressTextView.setText(R.string.status_unknown);
progressBar.setProgress(progress);
break;

}

}
I want to free up more space on the screen after downloading
How can I understand the download is completed?
I’d appreciate your cooperation.

Show custom interstitial ad like as admob interstitial ad

We are currently using admob's interstitial ad in our app. What we have in our first splash screen is:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
getWindow().setNavigationBarColor(getResources().getColor(R.color.colorPrimary));
}
setContentView(R.layout.activity_splash);
mContext = this;
requestNewInterstitialList();
}
private void requestNewInterstitialList() {
InterstitialAd mInterstitialAd = new InterstitialAd(this);
mInterstitialAd.setAdUnitId(getString(R.string.gl_start_app_inter));
mInterstitialAd.loadAd(new AdRequest.Builder().build());
mInterstitialAd.setAdListener(new AdListener() {
#Override
public void onAdOpened() {
super.onAdOpened();
mContext.finish();
}
#Override
public void onAdLoaded() {
super.onAdLoaded();
if (mInterstitialAd != null && mInterstitialAd.isLoaded()) {
Intent intent = new Intent(SplashActivity.this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
mInterstitialAd.show();
}
}
});
}
I requested interstitial from onCreate() in our splash screen. Notice that in interstitial ad in onAdLoaded() I started MainActivity.class via intent and this will definitely start that screen without closing interstitial ad! So, it will just start new screen in background and show interstitial ad at a time! After that in onAdOpened() of ad I just finished my current activity(Splash screen) and that also that not affect the interstitial ad and in mean while when user close the ad in the behind main screen is loaded!
Now situation is that we have some sponsors and they want show custom built interstitial ad in our App! So, I made that in DialogFragment:
public class DF_Interstitial_Ad extends DialogFragment {

This is my DialogFragment in which I implemented my own custom interstitial ad. So, after that I just request it regularly same as admob's interstitial ad from splash screen like:
private void requestMyInterstitialAd() {
DF_Interstitial_Ad dfInterstitialAd = new DF_Interstitial_Ad(mContext, "https://booads.s3.ap-south-1.amazonaws.com/output.mp4");
dfInterstitialAd.setmAdListener(new InterAdListener() {
#Override
public void onLoaded() {
super.onLoaded();
if (dfInterstitialAd != null && dfInterstitialAd.isLoaded()) {
Intent intent = new Intent(SplashActivity.this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
dfInterstitialAd.show(getSupportFragmentManager(), "SplashScreen");
}
}
#Override
public void onShow() {
super.onShow();
}
#Override
public void onClose() {
super.onClose();
}
});
}
It is show next screen(MainActivity) in front of screen rather than DialogFragment of ad! So, what to do? for showing ad in front of user and in mean while open next activity behind the ad! I already tried showing ad in activity rather than DialogFragment but its also not working for me!

I have only one fragment and I want to change this fragment in viewpager dynamically according to recycler view item data

my problem is same as link given below
I have a ViewPager by same fragments RecyclerView just load items in one fragment of ViewPager
but at this post no one solve issue...
I have a recycler view items...I want when I click on recycler view item it takes me to viewpager fragment and shows that data of clicked item dynamically and on swiping viewpager it should move previous and next fragment accordingly...under fragment I want to show data of recyclerrview item using single fragment...
I have done this by using multiple fragment and using multiple instances by different name and different layout name and different id for its recyclerView and it works but i have a large number of fragments and it is not the solution for me ):
here is my viewpager code
public class AndroidViewPagerExample extends FragmentActivity {

int positionring;

rgtv= it.getStringExtra("name");
pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
pager.setPageTransformer(true, new RotateUpTransformer());
pager.setCurrentItem(position);

userScrollChange = true;
else if (previousState == pager.SCROLL_STATE_SETTLING

}

Skipped 98 frames! The application may be doing too much work on its main thread

I have navigationdrawer with nav menus. When clicking on each nav menus, specific fragment opened. Each fragment display recylerviews who fetch data from SQLite external database.Now when open new fragment, little seconds must wait and when to click on each item for go to next activity for display details information about the item, 5 seconds must wait to open Details Activity. I know this is a problem for fetching data in main Thread and fetch bitmap in the main thread.But I don't know how to solve this problem with use AsyncTask.My big problem is an open new activity for display information and waiting for 5 seconds.
This is my asiafragment.

Update custom adapter with query results

i want to query results from custom adapter by comparing query text with list in RecycleView, it successfully gets results from query then i make list of results and update the existing adapter but it does not effect anything, i use below code fot that
combinationMessagesList = createCombinationMessagesList();
combinationMessages = createCombinationMessagesList();
combinationMessages.clear();
for (int i = 0; i < combinationMessagesList.size(); i++) {
CombinationMessage message = combinationMessagesList.get(i);
if (message.getBody().toString().equals(search.getText().toString())){
combinationMessages.add(combinationMessagesList.get(i));
}
}
messagesAdapter.setList(combinationmessagesList);
messagesAdapter.notifyDataSetChanged();

it was my own mistake it code, i made the code work by changing messagesAdapter.setList(combinationmessagesList)
to
messagesAdapter.setList(combinationMessages);
