Question

I want to save media-player object when orientation changes from portrait to landscape mode.
As i know when you change your orientation your activity get recreated so thats why my old media player object get distroyed.i tried onretainNonConfigureInstance method but it wont work for me.

I want old media player object in landscape view to display felixpalmer android-visualizer. To display Visualiser you need to link media player object with visualiser-view.
IS there any alternative way to pass old media player object to landscape view and vice versa??

Answer 1

Maybe you could just keep your media player object in a static variable inside the activity so it’ll be preserved on orientation changes.

Even though I’ve never used the Android Visualizer component, checking the source code of its VisualizerView class I see that it uses the Android’s Visualizer class.

As you can see in the documentation of the setCaptureSize method, it cannot be called while the Visualizer is enabled.

This is what I would try to do for your usage pattern:

Option 1

Call the release() method of the VisualizerView class when the screen orientation changes because that will call also the release() method of the Android’s Visualizer object thus releasing all the resources and allowing you to create a new one with a call to link() on the VisualizerView object to link your media player again.

Option 2

Take a look at this question and its answer. You could try to modify the source code of the VisualizerView class and insert mVisualizer.setEnabled(false) inside the link() method right after the creation of a new Visualizer instance and before the setCaptureSize call.
