If you elevate permissions you can also play URLs from inside a Kindlet, using the reflection technique described here: https://www.mobileread.com/forums/sho...79&postcount=4

Here is a method that plays a mp3 from a URL. Setting up callbacks should be possible, although tedious, using reflection.

    private void playAudioFromUrlWrapper (final URL url) {
    	setDescription("Initiating connection");
		final ConnectivityHandler handler = new ConnectivityHandler() {
			public void connected() {
				try {
					playAudioFromUrl(url);
				} catch (IllegalStateException ise) {
					ise.printStackTrace();
				}
			}

			public void disabled(NetworkDisabledDetails details) {
				;
			}
		};
    	context.getConnectivity().submitSingleAttemptConnectivityRequest(handler, true);
    }
    
    private void playAudioFromUrl (URL url) {
        Class contextClass = context.getClass();
        Method[] methods = contextClass.getDeclaredMethods();
        Method audioMethod = methods[1];
        Object audioManagerObject;
        Class audioManagerClass;
        
        try {
        	audioManagerObject = audioMethod.invoke(context, new Object[0]);
        	audioManagerClass = audioManagerObject.getClass();
        	
        	Method[] audioManagerMethods = audioManagerClass.getDeclaredMethods();
        	Method createAudioPlayerMethod = audioManagerMethods[10];
        	Class mediaSourceClass = createAudioPlayerMethod.getParameterTypes()[0];
        	Constructor[] mediaSourceConstructors = mediaSourceClass.getConstructors();
        	//Constructor mediaSourceInputStreamConstructor = mediaSourceConstructors[3];
        	Constructor mediaSourceUrlConstructor = mediaSourceConstructors[1];
        	
        	Object[] mediaSourceArgs = new Object[1];
        	mediaSourceArgs[0] = url;
        	Object mediaSourceObject = mediaSourceUrlConstructor.newInstance(mediaSourceArgs);
        	
        	Object[] createAudioPlayerArgs = new Object[1];
        	createAudioPlayerArgs[0] = mediaSourceObject;
        	Object audioObject = createAudioPlayerMethod.invoke(audioManagerObject, createAudioPlayerArgs);
        	Class audioClass = audioObject.getClass();
        	
        	Method[] audioMethods = audioClass.getDeclaredMethods();
        	Method playMethod = audioMethods[12];
        	playMethod.invoke(audioObject, new Object[0]);
