How to open password protected PDFs?

black border around content

Hello,
I'm trying to use PDFRenderer to convert a PDF file generated by the Android' PrintManager
Below is this generated pdf file which seems perfectly correct.
TestPrint.pdf
And here is the code I use to convert this file in a bitmap.

    mCurrentPage = mPdfRenderer.openPage(index);

    int width = (int)(203.0 / 72.0 * mCurrentPage.getWidth() + 0.5);
    int height = (int)(203.0 / 72.0 * mCurrentPage.getHeight() + 0.5);

    Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);

    mCurrentPage.render(bitmap, null, null, PdfRenderer.Page.RENDER_MODE_FOR_PRINT);

And below is the generated Bitmap. could you please tell me where does this 80 pixels wide black border comes from?

Cannot open PDF file after open wrong file

I have a file: pdf.txt. I rename it to: pdf.pdf
Below is my steps:

1. Open app. Open file "sample.pdf". -> OK
2. Open file "pdf.pdf" -> show Toast: "Error! file not in PDF format or corrupted"
3. Open file "sample.pdf" again. -> show Toast: "Error! file not in PDF format or corrupted"
   Now I cannot open PDF file.
   If I kill app, and open app again. File "sample.pdf" show ok. And if I open wrong file. I cannot open any files more.
   How can I resolve this issue? Thank you

Upstream issue with PdfRenderer

"This is an odd one; it's probably a variation on Issue #82838, in which when attempting to use PdfRenderer to display Assets, the wrong Asset is used.

What seems to be the problem is that behavior of PdfRenderer to display Assets depends upon the order of entries within the .apk. If the META-INF entries are first in the .apk, then PdfRenderer won't display PDF assets at all."

https://code.google.com/p/android/issues/detail?id=82841

can not read custom fonts

Hi this is a link which client want to read. PdfRenderer cannot read it.
