android-resources

I am trying to play an audio file in Android but it seems to crash and give a the ResourcesNotFoundException . The audio file is saved in the raw folder inside res. The name of the audio file is determined by a randomly generated number which is then concatenated to "audio". int res = getResources().getIdentifier ( "audio"+arrayIndex, "raw","com.din.askak" ); MediaPlayer mPlayer = MediaPlayer.create ( MainActivity.this, res ); In the logcat it seems to throw the exception on the line creating the mediaPlayer. I don't know what I seem to be doing wrong??? Mohamed Fadl Allah Use of getIdentifier

Below is my code: File pdfFile = new File( "android.resource://com.dave.pdfviewer/" + R.raw.userguide); Uri path = Uri.fromFile(pdfFile); Intent intent = new Intent(Intent.ACTION_VIEW); intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); intent.setDataAndType(path, "application/pdf"); startActivity(intent); However when I run it and press the button it says "The document cannot be opened because its is not a valid PDF document". This is driving me mad. Am I accessing the file correctly? Any ideas? Thanks You have to copy

I'm using Xamarin for Android and I'm using the support libraries. The project work fine, but after updating the support repositories from 23.1.1.1 to 23.3.0 , the Resource.Designer.cs is broken.
