the demo is working, I only change the sample.pdf to my own pdf.

That error means that mPdfRenderer = new PdfRenderer(mFileDescriptor) in the openRenderer method was not called, which will not happen just by adding some permissions or replacing the PDF file. What else have you changed? Did you change the logic around openRenderer? Feel free to reopen the issue if this doesn't work.

[jadiaheno]

i have the exact same problem

[namealperalp]

Same problem w aide ide

[joselitofilho]

I have the same problem.

[gunjot-mansa]

Any solution to the issue?

[swetakadam]

any solution still the same ... I have just replaced file ... not changed any other code

[swetakadam]

@yaraki -- it is not working please can we open this again

[yaraki]

Can you provide a project to reproduce the issue?

[swetakadam]

@yaraki -- I solved the issue for me ... .. check this discussion they provide deeper details https://code.google.com/p/android/issues/detail?id=82841 ... sorry could not give example project ... even if you checkout google sample .. and replace sample.pdf to some other file in assets .... it will keep displaying sample.pdf .. or sometimes keep throwing above error ..

My fix was --

I am not reading from assets ... assets directory is causing issues SDcard -- files on it work as a charm ..

Another important change done by me is -- the code from onDetach is moved to onDestroy ...

I will investigate further about assets directory .. for now I wasted a day and half on this example just to change the file

[yaraki]

As README.md says, if you are using a file from assets, include this in your build.gradle.

android {
    aaptOptions {
        noCompress "pdf"
    }
}

[swetakadam]

I did that too .. as filed from assets are compressed ...

[wangchauyan]

@swetakadam I think you might upgrade gradle version to 2.2.0, when I upgrade gradle version to 2.2.0, then this crash will happen. So, you should keep gradle version as 2.1.2.

@yaraki I also create a PR, please have a look

[yaraki]

Chauyan, thanks for the report. It seems that Android gradle plugin 2.2.0 has a bug with aaptOptions: https://code.google.com/p/android/issues/detail?id=224273

[wangchauyan]

@yaraki , thank you for reporting.

[wei-spring]

hi ,you can also change .pdf file from assets to res/raw ,then everything is ok. change code : mFileDescriptor = context.getAssets().openFd("sample.pdf").getParcelFileDescriptor(); to Resources res = context.getResources(); mFileDescriptor = res.openRawResourceFd(R.raw.sample).getParcelFileDescriptor();
