Android Expansion file won't trigger onDownloadStateChanged?
<p>I'm trying to make my app download an expansion file. Here's my code so far.</p>

<pre><code>public class main extends Activity implements IDownloaderClient {

TextView tv1;
Button mcButt;

@Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

  //////////
  tv1 = (TextView)findViewById(R.id.textView1);

  // Check whether the file have been downloaded.
  String mainFileName = Helpers.getExpansionAPKFileName(this, true, 1);
  boolean fileExists = Helpers.doesFileExist(this, mainFileName, 32921796L, false);

  if (!fileExists) {

   Intent launcher = getIntent();
   Intent fromNotification = new Intent(this, getClass());
   fromNotification.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
   fromNotification.setAction(launcher.getAction());

           if (launcher.getCategories() != null) {
                for (String cat : launcher.getCategories())
                { fromNotification.addCategory(cat); }
           }

   PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, fromNotification, PendingIntent.FLAG_UPDATE_CURRENT);

   try {

    int result = DownloaderClientMarshaller.startDownloadServiceIfRequired( this, pendingIntent, ExpansionFileDownloaderService.class);
    if (DownloaderClientMarshaller.NO_DOWNLOAD_REQUIRED != result) {

        // implement Downloading UI.
        tv1.setText("Need to download.");

     return;
    }

   } catch (Exception e) { 
    Log.e("apk-expansion-files", "NameNotFoundException occurred. " + e.getMessage(), e);
   }
  }

  tv1.setText("Downloaded!");


 }


///////////////////////////////////////////////////


@Override
public void onServiceConnected(Messenger m) {
    tv1.setText("onServiceConnected: " + m.toString() );
}

///////////

@Override
public void onDownloadStateChanged(int newState) {
    tv1.setText("onDownloadStateChanged: " + String.valueOf(newState) );
}

////////////

@Override
public void onDownloadProgress(DownloadProgressInfo progress) {
    ProgressBar mPB = (ProgressBar)findViewById(R.id.progressBar1);

    progress.mOverallTotal = progress.mOverallTotal;
    mPB.setMax((int) (progress.mOverallTotal &gt;&gt; 8));
    mPB.setProgress((int) (progress.mOverallProgress &gt;&gt; 8));
    tv1.setText(Long.toString(progress.mOverallProgress * 100 / progress.mOverallTotal) + "%");
    tv1.setText(Helpers.getDownloadProgressString(progress.mOverallProgress,progress.mOverallTotal));

}
</code></pre>

<p>}</p>

<p>The file does download fine, but it does not trigger onDownloadProgress or onDownloadStateChanged during or after download.</p>

<p>What comes to mind, is that DownloaderClientMarshaller need to be somehow connected with IDownloaderClient which is implemented into the activity...</p>

<p>Any ideas? Thanks!</p>
