Android Error code -3 when initializing Visualizer

Got this error while initializing Visualizer

visualizer = new Visualizer(mediaPlayer.getAudioSessionId()); <----

Error: Cannot initialize Visualizer engine, error: -3 java.lang.RuntimeException: Cannot initialize Visualizer engine, error: -3

NB : This is only happening in Marshmallow

Solution

  • Got the cause of the problem !!!

    This is caused for dynamic permission problem for Marshmallow.

    It requires RECORD_AUDIO permission to initialize it.

    I need to give permission Manifest.permission.RECORD_AUDIO before initialize the visualizer.
