Android – getIdentifier always returns 0 (library +application)

I have Android project ( which uses Android library (com.appocaliptic.quizknife.core).

What I am trying to do, is to get resource id of the picture which is the library. Path to the image is: res/drawable-xhdpi/fr_200_133.png

  • However, all tries with getIdentifier result 0. Where is the problem?

    resId = getResources().getIdentifier("fr_200_133", "drawable", "com.appocaliptic.quizknife.core");
    resId = getResources().getIdentifier("com.appocaliptic.quizknife.core:drawable/"+"fr_200_133", null, null);
    resId = getResources().getIdentifier("drawable/fr_200_133", null, "com.appocaliptic.quizknife.core");


    Ach, and in there is drawable and corensponding attribute.

    You should not be using the library package name. Try this instead:

    resId = getResources().getIdentifier("fr_200_133", "drawable", getPackageName());

    (or getContext().getPackageName() if this is executing in a view).

    I faced the same problem: “getIdentifier result 0” and i solved it by removing image extension (*.jpg, *.jpeg,… etc) to be match the name as it in file

    I was getting the same error and the only thing that worked was going about it in a different way:

    resourceId = R.drawable.class.getField("fr_200_133").getInt(null);

    I had a similar issue. I could resolve it similar to what Hussam Otri mentions. For example:

    //This doesn't work
    context.getResources().getIdentifier("audio_1.mp3", "raw", this.getPackageName()); 
    //This works (strip off the file extension)
    context.getResources().getIdentifier("audio_1", "raw", this.getPackageName());
