Deprecated ManagedQuery() issue

Question

I have this method:

public String getRealPathFromURI(Uri contentUri) {
    String[] proj = { MediaStore.Images.Media.DATA };
    Cursor cursor = managedQuery(contentUri, proj, null, null, null);
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}

Unfortunately the compiler show me a problem on:

Cursor cursor = managedQuery(contentUri, proj, null, null, null);

Because managedQuery() is deprecated.

How could I rewrite this method without use managedQuery()?

You could replace it with context.getContentResolver().query and LoaderManager (you'll need to use the compatibility package to support devices before API version 11).

However, it looks like you're only using the query one time: you probably don't even need that. Maybe this would work?

public String getRealPathFromURI(Uri contentUri) {
    String res = null;
    String[] proj = { MediaStore.Images.Media.DATA };
    Cursor cursor = getContentResolver().query(contentUri, proj, null, null, null);
    if(cursor.moveToFirst()){;
       int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
       res = cursor.getString(column_index);
    }
    cursor.close();
    return res;
}
