Set Notification Sound from Assets folder

问题

I am attaching the sound files in the assets folder for play sound in the notification but I am not able to play sound from the assets folder.

I have setting page from which user can set the sound for the notification and also user can play sound. This part is completed. I am able to play sound from the assets folder using Media Player. I can use same logic at the Notification creation time but problem can be happened when user click on the Notification because media player still playing the sound.

I tried

notification.sound = Uri.parse("file:///android_asset/Sound/Long/AlarmClock.mp3");

also tried like this

notification.sound = Uri.parse("android_asset/Sound/Long/AlarmClock.mp3");

but my issue is still not solved.

Is there any other way to set the sound in the notification from the assets directory ?

put ur mp3 file in res->raw folder, try to fetch sound file from raw folder.

Uri path = Uri.parse("android.resource://com.androidbook.samplevideo/" + R.raw.myvideo);

OR

Uri path = Uri.parse("android.resource://com.androidbook.samplevideo/raw/myvideo");

This worked perfectly for me. I found it on another post.

notification.sound = Uri.parse("android.resource://my.package.name/raw/notification");

回答3:

assets are private resources to that app, I think you wont be able to set them as ringtone, you will need a public file which is accessible by the media process to set ringtone. You will have to copy the file to sdcard to set it as ringtone.

回答4:

The correct path to load something from your assets folder is file:///android_assets/relative_path_to_your_file. Note the three slashes here. Although I have not tried to set a notification sound this way, I have used this with a WebView with success a number of times, and would expect it to work the same way.

I was not able to access directly the assets audio file to the Notification. So i follow this steps and so I am able to play audio in the Notification

1. I copy that files to the data directory.
2. Still data directory is not accessible to the Notification sound so I create a custom Content Provider to share the audio file in the read more which are now in data folder.
3. Now at the time of notification creation I had set the Uri of the file to the Notification sound.

Now using this steps I am able to set custom sound to the Notification.

ContentProvider is the way to go. I don't think there is a need to copy files to the data directory like @Dharmendra suggests. You can access the asset folder directly though the ContentProvider

public AssetFileDescriptor openAssetFile(Uri uri, String mode)
        throws FileNotFoundException {
    String filePart = Sound.getSoundFileName(uri);

    try {
        return getContext().getResources().getAssets().openFd(filePart + ".ogg");
    }catch(IOException e) {
        Log.d(TAG, "fail " + e.getMessage());

    }
    return null;
}
