Android - How do I open a file in another app via Intent?

Question

I\'m trying to open a file using another app, i.e. opening a .jpg with Gallery, .pdf with Acrobat, etc.

The problem I\'m having with this is when I try to open the file

Answer 1

I used this piece of code and it worked perfectly fine on android 6 and below not tested on the higher version

public void openFile(final String fileName){
    Intent intent = new Intent(Intent.ACTION_VIEW);
    Uri uri = Uri.fromFile(new File(android.os.Environment.getExternalStorageDirectory()
            .getAbsolutePath()+ File.separator+"/Folder/"+fileName));
    intent.setDataAndType(uri, "audio/mpeg");
    startActivity(intent);
}
