Question

I am using the DownloadManager to download images off our server and I am placing the files in the externalFilesDir.

I am send out a broadc

Answer 1

It seems that google is trying to prevent this from KITKAT.
Looking at core/rest/AndroidManifest.xml you will notice that broadcast android.intent.action.MEDIA_MOUNTED is protected now. Which means it is a broadcast that only the system can send.

<protected-broadcast android:name="android.intent.action.MEDIA_MOUNTED" />

The following should work for all versions:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    final Intent scanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    final Uri contentUri = Uri.fromFile(outputFile); 
    scanIntent.setData(contentUri);
    sendBroadcast(scanIntent);
} else {
    final Intent intent = new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + Environment.getExternalStorageDirectory()));
    sendBroadcast(intent);
}

If the above is not working try the following:

According to this post you need another way to fix it.
Like using MediaScannerConnection or ACTION_MEDIA_SCANNER_SCAN_FILE.

MediaScannerConnection.scanFile(this, new String[] {

file.getAbsolutePath()},

null, new MediaScannerConnection.OnScanCompletedListener() {

public void onScanCompleted(String path, Uri uri)

{


}

});

I know it's late but try this, it works in every version:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    Uri contentUri = Uri.fromFile(out); // out is your output file
    mediaScanIntent.setData(contentUri);
    this.sendBroadcast(mediaScanIntent);
} else {
    sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
        Uri.parse("file://" + Environment.getExternalStorageDirectory())));
}
