OutOfMemoryError Exception while passing audio file from asset folder

Question

Code:

AssetManager am = ctx.getAssets();

        try {

            InputStream is = am.open("kalimba.mp3"); // use recorded file instead of getting file from assets folder.

            int length = is.available();
            Log.v("Length", ""+length);

            audio_data = new byte[length];
            int bytesRead=0;

            ByteArrayOutputStream output = new ByteArrayOutputStream();

            while (bytesRead  != length)

            {
                Log.v("BytesRead", ""+bytesRead);
                Log.v("Audio Data", ""+audio_data);
                output.write(audio_data,bytesRead,length-bytesRead);

            }

          inarry = output.toByteArray();

where do you want to pass your mp3 file? why are you converting that to byte array..? — Rethinavel, Oct 22 '13 at 12:07
I'm encrypting the audio file and saving that file to sdcard.. This code working for a file which is of less than 3MB. If m using a size of more than that.. this exception take place... — Pandiri Deepak, Oct 22 '13 at 12:08

Looks like you are not updating your bytesRead at all, and it always stays at 0. This way your while() runns forever(in your case - until OutOfMemory)
Also I did not notice you reading any data from is(your input stream) into buffer(audio_data)
