# Why can't I play the audio file using startAudioMixing or playEffect on Android 9? (/en/api-reference/faq/integration/android_startaudiomixing_permission)

Cannot play an mp3, mp4, or any other music format using `startAudioMixing` or `playEffect` on Android 9.

## Reason [#reason]

This is caused by an Android permission limit. If `targetSdkVersion` >= 28, you need to add relevant app privileges to play the a music file.

## Solution [#solution]

For Android projects with `targetSdkVersion` >= 28, add the following line in the `application` zone of the AndroidManifest.xml file to play the music file:

```xml
<application
   android:usesCleartextTraffic="true"
   android:requestLegacyExternalStorage="true"
   …
</application>
```
