android-context

This is Android Project. Using Normal Build was successfull, but using signed Key i got this error : Execution failed for task ':transformClassesAndResourcesWithProguardForFlavorRelease'. > java.io.IOException: java.lang.IllegalArgumentException: Can't find common super class of [android/content/Context] (with 2 known super classes) and [com/onesignal/ADMMessageHandler] (with 1 known super classes) Any Idea ? Thanks in advance... I think Proguard causes this problem. Add this line to your Proguard file. -keep class com.onesignal.** { *; } And you should read this issue. It may help you. https:

My misunderstanding continues ... Can anyone cite references for the proper use of get*Context() ? I get conflicting recommendations about using getBaseContext() , getApplicationContext() and getContext() and my understanding is that using this is a convenience to get*Context() . I would like to study more specifically of what Dalvik is intending its object and access methods. I had code reviews that changed my calls to getBaseContext() to getApplicationContext() , now I am seeing suggestions to use this. theWook http://android-developers.blogspot.co.uk/2009/01/avoiding-memory-leaks.html Read

I am just finding what is the fact behind not using Context inside doInBackground() . In-fact we can't update the UI inside doInBackground() directly, to update the UI inside doInBackground() we have to call other thread via publishProgress() method which is responsible to call onProgressUpdate() . So in short I just wanted to know what is the chemistry between UI thread and AsyncTask , and why AsyncTask execute in UI Thread. Q Why Context can't be used in doInBackground() of AsyncTask? Context as the name suggests, its the context of current state of the application/object. It lets newly

I can't seem work out why I am getting a null pointer on this? This is my AsyncTask that I call to grab the data. It passes it to a JSON Parser and an array of Objects is returned. This is then passed to my DBHelper where it was passing to my database through a ContentResolver.... public class getFilms extends AsyncTask<String, Void, Void> { public int LIMIT_FILMS = 10; String KEY = "apikey"; String LIMIT = "limit"; private static final String URL = "http://api.rottentomatoes.com/api/public/v1.0/lists/movies/box_office.json?"; private static final String API_KEY = "******************";

This is a followup to this post: findViewById in a subclassed SurfaceView throwing RuntimeException Based on Romain Guy's feedback (which I'll accept shortly as it is a solution), I'd like to obtain the calling Activity from within the View, so that I can use it to obtain the desired TextView resource. I don't see any methods in View that return Activity. What is the proper way to do this? Or is there a better alternative for working with TextViews from within another View context. Basically, I am calling setContentView(R.layout.xxx) in onCreate() (as usual), so I don't really have a way to
