How do I catch content provider initialize?

Question

As we know content provider loads on application run. But I want to make some operations before content provider will launch. How do I catch this operation? Before content p

Answer 1

My solution requires use of the call(Uri, String, String, Bundle) API (so, it's not fully backward-compatible). But I have the stuff that I want the ContentProvider to prepare before it is used in my override of that call method. Then I do getContentResolver().call(BASE_URI, METHOD, null, Bundle.EMPTY) in my Application.onCreate(). Essentially, it defers that stuff until after my Application is being created, which is what we expected the ContentProvider's onCreate to be doing naturally.

Answer 2

I think Ive found solution. Ive created my custom application class and overridden attachBaseContext method

<application android:name=".ApplicationController" ...>

public class ApplicationController extends Application {
    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);

        // some of your own operations before content provider will launch
    }
}
