Show PDF file in App

Question

I found this two possibilities to show a pdf file.

1. Open a webView with:

   webView.loadUrl(\"https://docs.google.com/gview?embedded=true&url=\"+

Answer 1

Android provides PDF API now with which it is easy to present pdf content inside application.

you can find details here

Below is the sample snippet to render from a pdf file in assets folder.

    private void openRenderer(Context context) throws IOException {
    // In this sample, we read a PDF from the assets directory.
    File file = new File(context.getCacheDir(), FILENAME);
    if (!file.exists()) {
        // Since PdfRenderer cannot handle the compressed asset file directly, we copy it into
        // the cache directory.
        InputStream asset = context.getAssets().open(FILENAME);
        FileOutputStream output = new FileOutputStream(file);
        final byte[] buffer = new byte[1024];
        int size;
        while ((size = asset.read(buffer)) != -1) {
            output.write(buffer, 0, size);
        }
        asset.close();
        output.close();
    }
    mFileDescriptor = ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_ONLY);
    // This is the PdfRenderer we use to render the PDF.
    if (mFileDescriptor != null) {
        mPdfRenderer = new PdfRenderer(mFileDescriptor);
    }
}
