PDFRenderer showing wrong PDF

Question

I'm having problems with PDFRenderer not changing the PDF it shows after the first run of the application, no matter what I do.

I'm using the code from the official PDFRenderer Sample from https://developer.android.com/samples/PdfRendererBasic/project.html and Android Studio.

Exact steps I take which can be used to replicate this:

1. Add 2 files to Application/src/main/assets: PDF_1.pdf and PDF_2.pdf

2. In PdfRendererBasicFragment.java, line 140 in function openRenderer, change

   mFileDescriptor = context.getAssets().openFd("sample.pdf").getParcelFileDescriptor();
   

   to

   mFileDescriptor = context.getAssets().openFd("PDF_1.pdf").getParcelFileDescriptor();
   

3. Run project; Everything works as expected

4. In code above, change "PDF_1.pdf" to "PDF_2.pdf"
5. Run project again; The application still shows PDF_1.pdf

I have tried starting a completely new emulator, removing PDF_1.pdf from assets folder, syncronizing assets and "clean / rebuild project" in Android Studio , but it still keeps displaying PDF_1.pdf after the first run.
