Why is my intent not working?


I'm trying to get the Equalizer intent work on my app, I call my system's built in equalizer like this:

Intent intent = new Intent(); intent.setAction("android.media.action.DISPLAY_AUDIO_EFFECT_CONTROL_PANEL"); if ((intent.resolveActivity(getPackageManager()) != null)) { // here is the changes // REQUEST_CODE is an any integer value startActivityForResult(intent, 0); } else { Toast.makeText(getBaseContext(), "device not supported", Toast.LENGTH_LONG).show(); }

The problem in my code is that it is opening, however, it doesn't change the audio quality at all. No matter how much I fiddle with the knobs, sound remains the same.

Spottily also does the same, they are not using any class because the interface of equalizer changes with respect to Android Version.

What did i miss?


In the manifest have you added the needed permissions:

<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

Check the following manifest as example: <a href="https://android.googlesource.com/platform/packages/apps/MusicFX/+/f2f3fcd148769c5189c0d41c6ca85a8f14e6b534/AndroidManifest.xml" rel="nofollow">link</a>

Have you also tried to request the permissions see the following link (<a href="https://developer.android.com/training/permissions/requesting.html" rel="nofollow">https://developer.android.com/training/permissions/requesting.html</a>)



Add this to your activity in your minifest to open default equlizer

</blockquote> <activity android:name=".YourActivity"> <intent-filter> <action android:name="android.media.action.DISPLAY_AUDIO_EFFECT_CONTROL_PANEL" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.CATEGORY_CONTENT_MUSIC" /> </intent-filter> </activity>
