BuildConfig.APPLICATION_ID + ".provider", imageFileToShare);
share.putExtra(Intent.EXTRA_STREAM, uri);

startActivity(Intent.createChooser(share, "Message"));

Answer

Change your provider.xml to a broader extend which is more convenient:

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path
        name="external_files"
        path="." />
</paths>

And then in java:

    public static void shareVideo(Context context, String fullPath) {
    try {
        File file = new File(fullPath);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            Uri videoUri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file);
            Intent intent = new Intent(Intent.ACTION_SEND);
            intent.putExtra(Intent.EXTRA_STREAM, videoUri);
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            intent.setData(videoUri);
            intent.addFlags(FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(Intent.createChooser(intent, "share title"));
        } else {
            Uri videoUri = Uri.fromFile(file);
            Intent intent = new Intent(Intent.ACTION_SEND);
            intent.putExtra(Intent.EXTRA_STREAM, videoUri);
            intent.setDataAndType(videoUri, "video/*");
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(Intent.createChooser(intent, "share title"));
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Don’t forget to add this to your AndroidManifest.xml file:

<provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths" />
 </provider>
