Retrofit enqueue gets dismissed on orientation change

I am trying to upload plain text and image to the api using RetroFit. I want make sure the request continues to execute on orientation change. To do this, I have encapsulated the RetroFit api call inside a Headless fragment. This works fine when I try to upload an image. The request stops and resumes on device rotation. However it just gets cancelled on a text upload.
The only difference between the two uploads is that for image upload I use execute() and for text I use enqueue(). However, if I try to use execute() with the text, it still does not work.
Below is some code :-
UpdateTaskHelper (Headless fragment)
public static class UploadTaskHelper extends Fragment

private UploadAsync uploadTask;

How can I get the same behaviour for the text note? Any help is appreciated.

When you use enqueue your request sent async, and the orientation change destroys the activity and cancels your response code scope.
You should consider move the request code into a ViewModel class which is part of the MVVM architecture. The ViewModel would make the request even after orientation change and keep the data inside it, then you could access its data after the activity is re-created.

Google Play: update prices from IInAppBillingService

I created a class for working with subscriptions in the store.
In the beginning I receive from the server the list of subscriptions with the prices
The code is working and on most devices there is no problem.
But some users do not recive prices. It's like there's no response from the server. I've studied examples of implementation in Google documentation, but I can not understand where I can have problems in the code.
Part of my code:
public class BillingActivity extends AppCompatActivity {
RelativeLayout imageLayout;
View payButton;
// WebView payWebView;
// TextView useCodeButton;
ProgressBar progress1;
ProgressBar progress2;
ProgressBar progress3;
IInAppBillingService inAppBillingService;

public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_billing_subscription);

relative_1month.setOnClickListener(new View.OnClickListener() {

if (subscription1m != null) {
try {
Log.d("my", "purchase..." + subscription1m.storeName);
purchaseProduct(subscription1m);
} catch (Exception e) {
e.printStackTrace();
Log.d("my", "purchase error = " + e.toString());
}
}
}
});

}
}

my problem was the bit depth of the X variable priceAmountMicros
The price from playmarket is multiplied by a 1000000 , and Kazakh tenge has exchange rate = 1 USD= 331,3 KZT.
And if i have price 18 000 KTZ and * 1000 000.
For price variable I must use long type

How to wait for an activity to finish in asynctask

I know that the purpose of the AsyncTask is to run asynchronously with other tasks of the app and finish in the background, but apparently I need to do this, I need to start an activity from AsyncTask and since I cant extend an activity in this class I can not use startactivityforresult, so how can I wait till my activity finishes?

Would you please tell me what should I do to fix this code?

Looking over the code I did not see anywhere you referenced anything from the Activity itself besides the application context so you can move the ListSpdFiles class to its own java file and pass it a context into the constructor when you make a new instance of it.
Put this class in a ListSpdFiles.java file so it is no longer an inner class.
public class ListSpdFiles extends AsyncTask<Void, Void, String[]> {
Context applicationContext;
public ListSpdFiles(Context context, String initiator, String path) {
this.initiator = initiator;
this.path = path;
applicationContext = context.getApplicationContext();
}
// The rest of your code still goes here. Replace other calls to
// getApplicationContext() with the new applicationContext field
}
You can now use this class anywhere a Context is available. You create a new instance by doing:
ListSpdFiles listSpdFilesTask = new ListSpdFiles(context, "someInitiator", "somePath");
listSpdFilesTask.execute();

Flickr Sign out in Android programmatically

I am getting some issue when image is uploaded to flickr,oath token as well as user credentials get stored in the web browser cache.As a result am not being able to sign out from it.So when I go to flickr to upload my image again,it automatically uploads it rather than opening the login page.Now when I clear all the default browser cookies,then it ask for the login page.Is there any other way to sign out it automatically when I am redirected back to my application.Any kind of support will be appreciated.
Thanks in advance...
