Limitations on Opening Pdf File in Android

Limitations on opening pdf file in Android

I found a workaround to view my PDF on my Android application (but does not allow me to download it after show on the application). If I open my PDF using Google Docs I can open it with my Intent.

This is what I had to add before my url:

https://docs.google.com/gview?embedded=true&url=

so the final url will be like:

https://docs.google.com/gview?embedded=true&url=https://myUrl.pdf

Here is the whole code I am using right now:

String url= "https://docs.google.com/gview?embedded=true&url=https://url.pdf";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);

But it is still not enough, because I would like to open it without need of using a third party application. Also, opening PDF with Google Docs is slow and I have to wait too much until the PDF is finally opened.

If anyone knows how to open it with native Android please let me know.

What happens if I do not open it with Google Docs?

With the same code, but just using my url, instead the added Google Docs url, Android let me choose between two applications: Adobe Acrobat Reader and Google Chrome.

• If I open it with Google Chrome it download the PDF but it is not opened automatically.

• If I open it with Adobe Acrobat Reader, it gives to me the following error:

  The PDF cannot be shown (it cannot be opened)

Cannot open PDF file in external app

Ok guys, problem solved!

This is the code that i use to open a PDF file, stored on external memory:

File pdfFile = new File(Environment.getExternalStorageDirectory(),"namePdfFile.pdf");//File path
            if (pdfFile.exists()) //Checking if the file exists or not
            {
                Uri path = Uri.fromFile(pdfFile);
                Intent objIntent = new Intent(Intent.ACTION_VIEW);
                objIntent.setDataAndType(path, "application/pdf");
                objIntent.setFlags(Intent. FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(objIntent);//Starting the pdf viewer
            } else {

                Toast.makeText(getActivity(), "The file not exists! ", Toast.LENGTH_SHORT).show();

            }

How to prevent complete action using while opening pdf file using Adobe Reader.

I would like to thanks every one who tried to answer this question. After some browsing i found solution for my Question. which is perfectly working for me.

instead of using

intent.setPackage("com.adobe.reader");

I used

intent.setClassName("com.adobe.reader", "com.adobe.reader.AdobeReader");

don't forget to start activity in try catch block, it helps when adobe reader not installed on Device. Please check the below snippet.

try {
    Intent intent = new Intent();

    intent.setClassName("com.adobe.reader", "com.adobe.reader.AdobeReader");
    intent.setAction(Intent.ACTION_VIEW);
    intent.setDataAndType(Uri.fromFile(doc), "application/pdf");
    startActivity(intent);

   } 
   catch (ActivityNotFoundException activityNotFoundException) {
    activityNotFoundException.printStackTrace();
    }

Opening PDF file using Android intent

Please set intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

It will grant access of your file to other providers
