Adding Yandex Translator to Fragment leads to "App Crashes"

I'm Using Yandex Translator in my app, it works great if i'm using Activity, But when i add it to fragment , the app crashes before the launch.
Also no errors shown in the code , like everything is good, what could be the problem :
I looked for similar answers here, but i got nothing, no one had this issue before using fragments.
And here is the code for fragment :
public class FavoritesFragment extends Fragment implements TextToSpeech.OnInitListener{

Call setupInteraction() from onViewCreated(), not from onCreateView(). You are trying to use getView(), which will not work until onCreateView() returns.

How to save state of a progressbar when app is killed?

I am building a simple downloader app, with a pause/resume button. When I click on pause button and kill the app the download progress isn't shown anymore, after I open the app again. I want to save the download progress state even if the app is killed. Can anyone help me with this? I'm building the app using download manager pro library from github.

I don't know how you want to save the state but I do know that an activity has a onStop() method that you can override.
The onStop() method runs when the app is killed so I would imagine you would want to do your "saving" in this method.
As for saving something I believe you would want to use the SharedPreferences class. You can find more information about that here.
You can find the lifecycle of an activity here
hope this helps

Save the progress on SharedPreferences onDestroy() and retrieve it from there when activity is created.
Cache:
#Override
protected void onDestroy() {
super.onDestroy();
SharedPreferences sharedPreferences = getSharedPreferences("space_name", MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putInt("progress", progress).apply();
}
And retrieve:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SharedPreferences sharedPreferences = getSharedPreferences("space_name", MODE_PRIVATE);
progress = sharedPreferences.getInt("progress", 0); // 0 default value in case is empty
}

Why dialog for enabling dangerous android permissions is shown 2 times?

I am developing an app where I am using android's dialog for granting dangerous permissions. And when I click button for login on LoginActivity I go to Main activity and dialog is show. But when I press BACK button, again this dialog appears! This is my MainActivity(Just to say that my launcher activity is MAinActivity, not LoginActivity):
#Override
protected void onCreate(Bundle savedInstanceState) {

Activity Memory Leak reported by LeakCanary - WindowManagerGlobal

There is a memory leak reported by LeakCanary in my Android App. I have Googled and studied for days and cannot find any solution. The leaked object is an instance of Activity called "MakeFire". It seems to be related to android.view.WindowManagerGlobal. Can anyone point out how the leak happened, and how to fix it?
Here is the LeakCanary ScreenCap
Here is the source code of the MakeFire Activity

Getting incoming calls for an hour only using Twilio

I have implemented Twilio in my android app for outgoing and incoming calls. But I'm facing an issue while getting incoming call with the background service. The issue is that I get calls in first 30-40 mins only. After sometime phone stops getting incoming calls. I tried so much. Please respond me soon. I'm sharing code with you too.
I get token from a background service which generates token after a time period.
