Reading a pdf file placed in assets folder in android

问题

I have a pdf file placed in my assets folder and I am firing an intent to read it. Here is my code :

 Uri path = Uri.parse("file:///android:asset/about.pdf");
   Intent intent  = new Intent(Intent.ACTION_VIEW);
   intent.setDataAndType(path, "application/pdf");
   intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
   startActivity(intent);

When I do this, apop up appears with list of applications including adobe reader but when I click on it, a dialog appears saying :"Error", the file path is not valid

Please tell me how to fix this

Is this file in your app's assets folder? If it is, then your URI is wrong, check out this question:
