Getting FileNotFoundException When Trying to Share MP3 File Using FileProvider

Question

I'm trying to use a FileProvider to share an MP3 file stored in the raw folder of my app's internal storage and let a user use an audio-listening app of their choice to open the shared MP3 file.

However, with my code as written, I get a FileNotFoundException when I try to execute the intent with the content URI attached as data. This leads to everything else about the FileProvider system failing.

I created a MediaPlayer and had it open the MP3 file I want to share without a problem, so I know that the file exists and that my app is able to access it.

When debugging, I noticed that the content URI's path seems to get rid of the /files/ directory even though it's in the File that I use getUriFromFile on:

meditationFile: /data/user/0/com.example.selfcareapplication/files/raw/breathing_meditation.mp3

meditationFileContentUri: content://com.example.selfcareapplication.fileprovider/raw/breathing_meditation.mp3

Here is my code in my manifest file:

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

Here is the code where I try to use the FileProvider:

        Intent openMeditationFileIntent = new Intent(Intent.ACTION_VIEW);
        File meditationPath = new File(this.getFilesDir(), "raw");
        File meditationFile = new File(meditationPath, "breathing_meditation.mp3");

        Uri meditationFileContentUri = FileProvider.getUriForFile(this.getApplicationContext(), "com.example.selfcareapplication.fileprovider", meditationFile);
        openMeditationFileIntent.setData(meditationFileContentUri);
        openMeditationFileIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

        if(openMeditationFileIntent.resolveActivity(getPackageManager()) != null) {
            startActivity(openMeditationFileIntent);
        } else {
            Log.d(LOG_TAG, "Could not resolve activity");
        }

Here is the log I get when I try to start the intent with the content URI attached:

Answer 1

I created /raw directory in /res and copied the .mp3 file there

That is on your development machine.

What exactly is the difference between creating a raw/ directory and creating a raw resource if you don't mind my asking?

The difference is that getFilesDir() is referring to locations on the Android device. The raw/ directory that you created is on your development machine.

Doesn't moving a file into the /res/raw folder turn it into a raw resource that you can reference with R.raw?

Yes. However, that is not what your code is doing. Your code is attempting to reference it using File . Raw resources are files on your development machine. They are not files on the device.

You need to copy the raw resource ( getResources().openRawResource() , etc.) to a file, which you can then share using FileProvider .
