    intent.setType("application/pdf");
    intent.setPackage("com.adobe.reader"); selects the adobe reader directly 
    PackageManager pm = getPackageManager();
    List<ResolveInfo> activities = pm.queryIntentActivities(intent,0);

            {
    startActivity(intent);


    } else {
    Toast.makeText(this, "No Application Available to View PDF",

        Toast.LENGTH_SHORT).show();
    }

Answer 1

you can read pdf file from sdcard by giving the path and try the following.

File pdfFile = new File(path); 
if(pdfFile.exists()) 
{

    Uri path = Uri.fromFile(pdfFile); 
    Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
    pdfIntent.setDataAndType(path, "application/pdf");
    pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    try
    {
        startActivity(pdfIntent);
    }
    catch(ActivityNotFoundException e)
    {
        Toast.makeText(uractivity.this, resource.getString(R.string.noapplicationpdf), Toast.LENGTH_LONG).show(); 
    }
}
