Sending music file from one application to another

Question

I'm trying to send a music files from my app to other ones using this code. I already have WRITE_EXTERNAL_STORAGE permission enabled. But whenever I choose the app I want to share my file with it doesn't appear or I get Toast saying format not recognized.

                                    String filePath = songs.get(viewPosition).getPath();
                                    Uri uri = Uri.parse(filePath);
                                    Intent share = new Intent(Intent.ACTION_SEND);
                                    share.setType("audio/*");
                                    share.putExtra(Intent.EXTRA_STREAM, uri);
                                    mContext.startActivity(Intent.createChooser(share, "Share Sound File"));

Path I'm getting from filePath is for example something like this: /storage/emulated/0/Music/2Pac - better dayz - tupac - better days.mp3

Your path contains twice /storage/emulated/0 which does not look ok. — greenapps, Aug 14 '18 at 09:49
@ADM that gave me FileUriExposedException but thanks to that I found a solution. — Flyentology, Aug 14 '18 at 09:50

The problem with my code was due to change in how files are sent after Android N. Now apps should use content:// instead of file:// so the platform can extend temporary permission for the receing app. Only thing missing is File Provider that will change file:// into content:// in uri.

The whole solution for my problem is here: https://stackoverflow.com/a/38858040/8430049

So code should look like this:

                                    String filePath = songs.get(viewPosition).getPath();
                                    Uri uri = FileProvider.getUriForFile(mContext, "com.simplemusicplayer.fileprovider", new File(filePath));
                                    Intent share = new Intent(Intent.ACTION_SEND);
                                    share.setType("audio/*");
                                    share.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                                    share.putExtra(Intent.EXTRA_STREAM, uri);
                                    mContext.startActivity(Intent.createChooser(share, "Share Sound File"));

And android manifest needs to include provider:

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

Path app will give access to is stored in xml/provider_paths.xml

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

To think that I've been trying to solve this same issue. I'll definitely try this out and rate the answer. — Mbuodile Obiosio, Aug 14 '18 at 10:45

From the answer from @Flyentology I had to make a little change to get it to work.

<paths>
  <external-path name="external_files" path="."/>
  <root-path name="root" path="." />
</paths>
