this.nativeAudio.preloadSimple('uniqueId1', 'path/to/file.mp3').then(onSuccess, onError);
this.nativeAudio.preloadComplex('uniqueId2', 'path/to/file2.mp3', 1, 1, 0).then(onSuccess, onError);

this.nativeAudio.play('uniqueId1').then(onSuccess, onError);

// can optionally pass a callback to be called when the file is done playing
this.nativeAudio.play('uniqueId1', () => console.log('uniqueId1 is done playing'));

this.nativeAudio.loop('uniqueId2').then(onSuccess, onError);

this.nativeAudio.setVolumeForComplexAsset('uniqueId2', 0.6).then(onSuccess,onError);

this.nativeAudio.stop('uniqueId1').then(onSuccess,onError);

this.nativeAudio.unload('uniqueId1').then(onSuccess,onError);
