POAndroid : Stop Activity(s) after starting Service
text
Body
copied!<p>I have the following flow in my code:</p> <pre><code> Activity1 : startActivity(Activity2) ---> Activity2: startActivity(Activity3) ---> Activity3: startService(MyService) ---> MyService: startActivity(Activity4) </code></pre> <p>Each Activity above shows a single view and represents a step in a 4-step setup. The final Activity - <code>Activity 4</code> - is started after some setup work is done inside <code>MyService</code>, which basically tells the user, </p> <p><code>"The service has started, you can close the application by pressing Back or Home button"</code></p> <p>When the user presses Back or Home, I want to destroy <code>Activities 1-4</code> , and only have <code>MyService</code> running. Also, after stopping the Application as above, when the user navigates back to the Application via the menu and starts it, I'll be checking if <code>MyService</code> is already running. If it is already running, I don't want to show <code>Activities 1-3</code>, I want to show another <code>Control Panel View</code> (Another Activity), which says,</p> <p><code>"Dude, the service is already running, do you want to Stop or Restart it?"</code></p> <p>This view will have a Stop and Restart button, to do the appropriate tasks.</p> <p><strong>My Questions:</strong></p> <ol> <li><p>How do I stop Activities 1-4 from inside Activity 4 when Back or Home is pressed,safely? My thought was to add a <code>static stopActivity()</code> method to each Activity, and calling <code>Activity[1-3].stopActivity()</code> from <code>onBackPressed()</code> or <code>onPause()</code> of <strong>Activity4</strong>. Then inside each <code>stopActivity()</code>, I'll call <code>finish()</code>, thus ending each Activity. But is it safe and efficient to do it this way?</p></li> <li><p>The flow I have illustrated above, is it the optimal way of doing things, or is there a cleaner way? I have <code>BroadcastReceivers</code> registered in these Activities, so I need to perform clean exits for each Activity, without leaked receivers, or worse, crashing the App or affect the User's phone due to unclean exit strategies.</p></li> </ol> <p>Thanks for your suggestions.</p>
