    <p>I want to test my bound service with ServiceTestCase. The testing consists of binding to MyBindServer, and sending a Message. Watching the logs, you can see the service is started when onBind() is called, and a message is sent from testAHello(), but, the server's handleMessage() is never called.</p> <p>From the logs:</p> <pre><code>I/TestRunner( 2099): started: testAHello(com.inthinc.mybindserver.test.MyBindServerTest) I/MyBindServerTest( 2099): setUp() I/MyBindServer( 2099): onBind, action=com.inthinc.mybindserver.START I/MyBindServerTest( 2099): testAHello I/MyBindServerTest( 2099): sending SAY_HELLO [here is where I expect to see the output from handleMessage()] I/MyBindServerTest( 2099): tearDown() I/TestRunner( 2099): finished:testAHello(com.inthinc.mybindserver.test.MyBindServerTest) I/TestRunner( 2099): passed: testAHello(com.inthinc.mybindserver.test.MyBindServerTest) </code></pre> <p>Here is the code for MyBindServer.java:</p> <pre><code>package com.inthinc.mybindserver; import android.app.Service; import android.content.Intent; import android.os.Handler; import android.os.IBinder; import android.os.Message; import android.os.Messenger; import android.util.Log; public class MyBindServer extends Service { static final String TAG = "MyBindServer"; public static final int MSG_SAY_HELLO = 1; final Messenger mMessenger = new Messenger(new IncomingHandler()); class IncomingHandler extends Handler { @Override public void handleMessage(Message msg) { Log.i(TAG, String.format("handleMessage, what=%d", msg.what)); switch (msg.what) { case MSG_SAY_HELLO: Log.i(TAG, "hello"); break; default: super.handleMessage(msg); } } } @Override public IBinder onBind(Intent intent) { Log.i(TAG, String.format("onBind, action=%s", intent.getAction())); return mMessenger.getBinder(); } } </code></pre> <p>Here is the code for MyBindServerTest.java:</p> <pre><code>package com.inthinc.mybindserver.test; import com.inthinc.mybindserver.MyBindServer; import android.content.Intent; import android.os.IBinder; import android.os.Message; import android.os.Messenger; import android.os.RemoteException; import android.test.ServiceTestCase; import android.test.suitebuilder.annotation.SmallTest; import android.util.Log; public class MyBindServerTest extends ServiceTestCase&lt;MyBindServer&gt; { private static final String TAG = "MyBindServerTest"; Messenger mServer = null; public MyBindServerTest() { super(MyBindServer.class); } public MyBindServerTest(Class&lt;MyBindServer&gt; serviceClass) { super(serviceClass); } @Override public void setUp() { try { super.setUp(); Log.i(TAG, "setUp()"); Intent bindIntent = new Intent("com.inthinc.mybindserver.START"); IBinder binder = bindService(bindIntent); assertNotNull(binder); mServer = new Messenger(binder); } catch (Exception e) { e.printStackTrace(); } } @Override public void tearDown() { try { super.tearDown(); Log.i(TAG, "tearDown()"); } catch (Exception e) { e.printStackTrace(); } } @SmallTest public void testAHello() { Log.i(TAG, "testAHello"); assertNotNull(mServer); Message msg = Message.obtain(null, MyBindServer.MSG_SAY_HELLO); Log.i(TAG, "sending SAY_HELLO"); try { mServer.send(msg); } catch (RemoteException 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.

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