onReceive does not called after download completed

Question

I'm trying to use android downloadManager via this tutorial . I move broadCastReciever block in a single function, and below is my code:

public void downloadManager(){

    boolean is_downloaded = false;

        Log.e("error ", "1");
        receiver = new BroadcastReceiver() {

            @Override
            public void onReceive(Context context, Intent intent) {
                Log.e("error ", "2");
                String action = intent.getAction();

                if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
                     Log.e("error ", "3");
                     DownloadManager.Query query = new DownloadManager.Query();
                    query.setFilterById(enqueue);
                    Cursor c = dm.query(query);
                    Log.e("error ", "4");
                    if (c.moveToFirst()) {
                        Log.e("error ", "5"); 
                        int columnIndex = c.getColumnIndex(DownloadManager.COLUMN_STATUS);

                         if (DownloadManager.STATUS_SUCCESSFUL == c.getInt(columnIndex)) {
                            // download finished successfully
                            is_downloaded = true;
                            Log.e("error ", "6");
                        }
                    }
                }
            }
        };

       getActivity().registerReceiver(receiver, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));

     }

when I run the project, is_downloaded will remains false. and in logcat I can see just this line:

error: 1

means that the application control will never reach other Logs so

@Override
public void onReceive(Context context, Intent intent)

will never call. but the image downloads successfully. every thing seems OK, where is the problem?

It's not clear what you need this variable for, where do you check its value? — Egor, Sep 06 '16 at 11:22
i guess you must register your receiver to receive response in onReceive — Milad Faridnia, Sep 06 '16 at 11:27
@Milad yes, and I did that, ` getActivity().registerReceiver(receiver, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));` — Shima Erfan, Sep 06 '16 at 11:29
@ShimaErfan Ok its not the answer of your question but I guess you need this http://stackoverflow.com/a/3028660/2101822 see the 3rd one — Milad Faridnia, Sep 06 '16 at 11:38
are you sure that the activity where the receiver is registered doesn´t get killed in the meanwhile? — Opiatefuchs, Sep 06 '16 at 11:45
I can´t see where you have instantiated the `DownloadManager`....Do you only use this static methods or do you have implemented your subclass of `DownloadManager`? — Opiatefuchs, Sep 06 '16 at 12:02

Try to use <uses-permission android:name="android.permission.SEND_DOWNLOAD_COMPLETED_INTENTS" />

of course, do not forget this:

<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

if doesn't help try to use BroadcastListener

public class DownloadListenerService extends BroadcastReceiver {        
    @Override
    public void onReceive(final Context context, Intent intent) {
        System.out.println("got here");
       ///// your code here
        }
    }
}

`

    <receiver 
        android:name="com.example.DownloadListenerService"
        android:exported="true" >
        <intent-filter>
            <action android:name="android.intent.action.DOWNLOAD_COMPLETE" />
        </intent-filter>
    </receiver>
    <uses-permission android:name="android.permission.INTERNET" />

`

Part of code is from here: https://stackoverflow.com/a/18789470/1979882

I added the first permission, and the others existed. no difference — Shima Erfan, Sep 06 '16 at 11:49

try it through AsyncTask, keep isDownloaded false in onPreExecute() then download the content in doInBackground() and then assign true to isDownloaded in onPostExecute().
