Share file from my activity to another app using FileProvider not working

I am trying to share an mp3 file created in my app using the FileProvider. I followed the documentation and this Stack Overflow post, but it is not working: for example, gmail says "Can't attach empty file".

The mp3 files are saved in Environment.getExternalStorageDirectory()+"/MyApp".

I added the provider to the manifest:

<provider
   android:name="android.support.v4.content.FileProvider"
   android:authorities="com.myapp.fileprovider"
   android:exported="false"
   android:grantUriPermissions="true">
   <meta-data
       android:name="android.support.FILE_PROVIDER_PATHS"
       android:resource="@xml/file_provider_paths" />
</provider>

Added the file_provider_paths.xml to res:

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="share" path="MyApp/" />
</paths>

And added this method to my activity:

public void ShowShareChooser(String filename)
{
    Intent shareIntent = new Intent(Intent.ACTION_SEND);
    File f = new File(filename);
    Uri fileUri = FileProvider.getUriForFile(this,"com.myapp.fileprovider",f);
    String type = getContentResolver().getType(fileUri);
    shareIntent.putExtra(Intent.EXTRA_STREAM,fileUri);
    shareIntent.setType(type);
    //shareIntent.setDataAndType(fileUri,type); // another failed attempt
    shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    shareIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
    startActivity(Intent.createChooser(shareIntent, "Share song"));
}

When filename is "/storage/emulated/0/MyApp/Audio.mp3", the resulting fileUri is content://com.myapp.fileprovider/share/Audio.mp3. The type is audio/mpeg.

I am targeting API 22, and testing this on a Nexus 5 (6.0.1).

As it often turns out, it was a stupid mistake on my part. The file was not created anymore because of a new bug somewhere else in the code, while I assumed it was there. The code works indeed fine, I'll leave it here for future reference (and as a personal memento).
