    <p>Just to make it clear (because I used a lot of time figuring out how to make it work)</p> <p>In the service class that extends <code>BroadcastReceiver</code>. Put in the following code in <code>onReceive()</code></p> <pre><code>Intent intent2open = new Intent(context, YourActivity.class); intent2open.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent2open.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); String name = "KEY"; String value = "String you want to pass"; intent2open.putExtra(name, value); context.startActivity(intent2open); </code></pre> <p>The <code>FLAG_ACTIVITY_SINGLE_TOP</code> makes sure the apps doesn't re-open if already open. This means that the "old" intent that opened YourActivity in the first place is re-used and it will NOT contain the extra values. You have to catch them in another method called <code>onNewIntent()</code> in <code>YourActivity.</code></p> <pre><code>public class YourActivity extends Activity { private String memberFieldString; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Code doing your thing... } // End of onCreate() @Override protected void onNewIntent(Intent intent) { Log.d("YourActivity", "onNewIntent is called!"); memberFieldString = intent.getStringExtra("KEY"); super.onNewIntent(intent); } // End of onNewIntent(Intent intent) @Override protected void onResume() { if (memberFieldString != null) { if (opstartsIntent.getStringExtra(KEY) != null) { Log.d("YourActivity", "memberFieldString: "+ memberFieldString); } else { Log.d("YourActivity", "The intent that started YourActivity did not have an extra string value"); } } } // End of onResume() } // End of YourActivity </code></pre> <p>Please note the two if statements - the <code>onResume()</code> does not know if it's called after <code>OnCreate()-&gt;OnStart() OR onRestart()-&gt;onStart()</code><br> <strong>Please see:</strong> <a href="http://www.anddev.org/images/android/activity_lifecycle.png" rel="noreferrer">http://www.anddev.org/images/android/activity_lifecycle.png</a></p> <p>It's just used to test if the app is launched by the user (intent with no extras) OR by the <code>BroadcastReceiver</code> (intent with extras).</p>

    2. COThis might sound stupid: But have you checked if you have set the right flag and followed the description to every point? It took me a long time to figure this out and I realized that not all flags work like I would expect them to do. If you add more flags than described then try to remove them. Make that work and then add them one by one to see what happens.

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.

SQuiL has stopped working due to an internal error.

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