Question

I have downloaded some Office files(doc, xls, pdf etc) on SDcard from FTP server and now I want to view those files using third party application.

I am using below code for Intent (in this case a PDF File):

PackageManager packageManager = getPackageManager();
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setType("application/pdf");


        List list = packageManager.queryIntentActivities(intent,PackageManager.MATCH_DEFAULT_ONLY);


        if (list.size() > 0) 
        {
            Uri uri_path = Uri.parse(path);
            intent.setDataAndType(uri_path, "application/pdf");
            try
            {
                startActivity(intent);
            } 
            catch (ActivityNotFoundException e)
            {
                Toast.makeText(getApplicationContext(),"No Application Available to View PDF", Toast.LENGTH_SHORT).show();
            }
        }

But when I try to open the file a White Screen appears and disappears. And in DDMS I get the following:

Please help me on this issue. I don’t understand the problem. When I goto SDCard using “ES File Explorer” and opens the file, it gets opened. All the files(doc xls and PDF) gets opened correctly.

Answer 1

Got my answer. I needed to add the following for my URI:

File file = new File(path);
Uri uri_path = Uri.fromFile(file);
intent.setDataAndType(uri_path, "application/pdf");
try
{
    startActivity(intent);
} 
catch (ActivityNotFoundException e)
{
    Toast.makeText(getApplicationContext(),"No Application Available to View PDF", Toast.LENGTH_SHORT).show();
}
