    <p>Hi I'm currently developing an app that requires a very large download (100-200MB) on the first launch of the application.</p> <p>My first activity starts a service, which has an asynctask to do all the downloading.</p> <p>To show the progress of my download I'm doing the following:</p> <p>First using AsyncTask's publishProgress/onProgressUpdate I send a broadcast to my activity with the current progress:</p> <pre><code>@Override protected Void doInBackground(Void... params) { ... publishProgress(Integer.toString(completedFiles), current_filename, Integer.toString(file_progress)); ... } @Override protected void onProgressUpdate(String... progress) { super.onProgressUpdate(progress); progressBroadcast.putExtra(NOTIFY_DOWNLOAD_PROGRESS, progress); sendOrderedBroadcast(progressBroadcast, null); } </code></pre> <p>The on my activty I have a BroadcastReceiver that updates the progressbar</p> <pre><code> private class ProgressReceiver extends BroadcastReceiver{ private int totalFiles; public ProgressReceiver(Context context) { progressDialog = new ProgressDialog(context); } @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if(ResourceDownloadService.NOTIFY_DOWNLOAD_START.equals(action)){ progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); progressDialog.setCancelable(false); progressDialog.setTitle(getString(R.string.loading_res_dialog_title)); totalFiles = intent.getIntExtra(ResourceDownloadService.TOTAL_FILES, 0); progressDialog.setMessage("Downloading Resources"); progressDialog.show(); }else if(ResourceDownloadService.NOTIFY_DOWNLOAD_END.equals(action)){ //Hide progress bar one we are done progressDialog.dismiss(); startIntroActivity(); }else{ String[] progress_info = intent.getExtras().getStringArray(ResourceDownloadService.NOTIFY_DOWNLOAD_PROGRESS); int completedFiles = Integer.parseInt(progress_info[0]); String filename = progress_info[1]; int progress = Integer.parseInt(progress_info[2]); progressDialog.setProgress(progress); progressDialog.setMessage("Downloading "+filename +"\n"+completedFiles +" files downloaded of "+totalFiles); } } } </code></pre> <p>So I'm not sure of what I'm doing wrong here, because after a couple of seconds that the progress bar is showing I get an ANR.</p> <p>Could it be because I'm sending too much broadcasts to update the progress bar??</p>

    1. CO.....100-200MB, that's insane but that aside why are you using a broadcast receiver to do this, the AsyncTask's publishProgess method was designed specifically to update the UI from a background thread

    2. COI know, but I've seen a lot of games on the market do the same, and besides it will be only on the first launch of the app. I'm sending the progress as a broadcast because I'm using the AyncTask inside a Service which then sends a broadcast to the activity, so I if the activity is not present (config change ) the service will download the resources anyway

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
