Google Play崩溃报告中的AndroidRuntimeException

Question

I have an app on the Google play store and it works fine for most people. However there are 90 crashes reported, via Google crash report, with the following:

android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?
at android.app.ContextImpl.startActivity(ContextImpl.java:847)
at android.content.ContextWrapper.startActivity(ContextWrapper.java:276)

at dalvik.system.NativeStart.main(Native Method)

I've had a look around on the web but all I can find is to add intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); .

But this doesn't work for me as I don't call startActivity() in my code. I do call startActivityForResult() but specifying the FLAG_ACTIVITY_NEW_TASK flag stops the result being returned in onActivityResult() .

Here is the only piece of code that has startActivityForResult() called from onCreate() in my Main Activity:

private void load()
{
    Intent loadBeats = new Intent(this, BeatListActivity.class);
    startActivityForResult(loadBeats, SELECT_BEAT_ACTIVITY);
}

I've never actually had this error occur for me on any of my devices or in a Virtual Device! This all makes it difficult to solve.

Any ideas?

Answer 1

After the helpful comments, @ReubenScratton, following my question I think I've found the problem/solution!

In my code I do not use startActivity() so this confused me. However I do use AdView (admob adverts) version 4.1.1, which does seem to call startActivity() . I found this out after searching Google. Other people had reported the same errors, as per my question, using that version of AdView (GoogleAdMobAdsSdk-4-1-1.jar).

I've updated my app with a newer version and, so far, there have been no more errors!

I will report back if this is not the case thought.

Just Adding up

This exception also happens with interstitial ads

You have to pass the activity context not application context

InterstitialAd interstitial = new InterstitialAd(this);

Incase of fragments

InterstitialAd interstitial = new InterstitialAd(getActivity());

and not

InterstitialAd interstitial = new InterstitialAd(getActivity().getApplicationContext());
