    <p>What I have is multiple buttons. Using if-else statements, I download a file to that corresponding button. Now, I also define what class to open via intent in the if-else statement. I need to have it so that it will begin downloading the file and then start a new activity. I used to do this with an AsyncTask, and start the new intent in the onPostExecute, but I decided it's better to use DownloadManager. So, you may be confused. So I'll explain through my code...</p> <p>So, here I'm setting it all up:</p> <pre><code> BroadcastReceiver receiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) { long downloadId = intent.getLongExtra( DownloadManager.EXTRA_DOWNLOAD_ID, 0); Query query = new Query(); query.setFilterById(enqueue); Cursor c = dm.query(query); if (c.moveToFirst()) { int columnIndex = c .getColumnIndex(DownloadManager.COLUMN_STATUS); if (DownloadManager.STATUS_SUCCESSFUL == c .getInt(columnIndex)) { String uriString = c .getString(c .getColumnIndex(DownloadManager.COLUMN_LOCAL_URI)); } } } } }; registerReceiver(receiver, new IntentFilter( DownloadManager.ACTION_DOWNLOAD_COMPLETE)); </code></pre> <p>Ok. Now, in my if-else I declare the url to download, as well as setting a string equal to a class, and another string equal to the output file:</p> <pre><code>if (andy != null){ className = "com.cydeon.plasmamodz.Softkeys"; fileName = "batterymod.zip"; dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE); Request req = new Request( Uri.parse("https://dl.dropbox.com/s/gfukrwqy4xqrnj9/Android.zip")); req.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, fileName); enqueue = dm.enqueue(req); } </code></pre> <p>Ok. So all works good. Now, my showDownload:</p> <pre><code>public void showDownload(View view) { Intent i = new Intent(); i.setAction(DownloadManager.ACTION_VIEW_DOWNLOADS); startActivity(i); </code></pre> <p>Good. Now, it downloads. So, now that's it's downloading, I need to start a new activity. And, I've researched and tried some stuff, but nothing works. As you saw, I already set a class inside the string. I have this code which I used in the onPostExecute, so I know it works fine:</p> <pre><code> try { Intent openNewIntent = new Intent(Bmod.this, Class.forName(className) ); startActivity( openNewIntent ); } catch (ClassNotFoundException e) { e.printStackTrace(); } } </code></pre> <p>So, I'll repeat what I want. I want to download a file, and then, after executing the download, start a new activity. Any help is greatly appreciated. Thanks!</p> <p>Edit - Here's an updated code:</p> <pre><code> public void showDownload(View view) { Context context = getApplicationContext(); CharSequence text = "Download complete"; int duration = Toast.LENGTH_SHORT; Toast toast = Toast.makeText(context, text, duration); toast.show(); try { Intent openNewIntent = new Intent(Bmod.this, Class.forName(className) ); startActivity( openNewIntent ); } catch (ClassNotFoundException e) { e.printStackTrace(); } } </code></pre>

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.
