    <p>I am trying to implement a very simple service example. The user inputs the value through EditText and clicks on Calculate Button. The Calculate button triggers a service which performs some calculations and sends the result back to another EditText box. If I use a simple service without binding, the result gets displayed before the calculation is performed, so I want to use a bound service. But in my case, the control just stops at onBind call and onStart does not get executed. The control does flow to onCreate though. Could anyone help me to find where I am going wrong? </p> <pre><code>public class SimpleService extends Service { private final IBinder mBinder = new LocalBinder(); @Override public IBinder onBind(Intent intent) { // TODO Auto-generated method stub System.out.println("Service: OnBind"); return mBinder; } public class LocalBinder extends Binder { SimpleService getService() { System.out.println("Service: in Local binder"); return SimpleService.this; } } @Override public void onCreate() { super.onCreate(); System.out.println(" Service:In on create..."); Toast.makeText(this,"Service created ...", Toast.LENGTH_LONG).show() } @Override public void onDestroy() { super.onDestroy(); System.out.println(" Service:in on destroy..."); Toast.makeText(this, "Service destroyed ...", Toast.LENGTH_LONG).show(); } @Override public void onStart(Intent intent, int startid) { System.out.println("Service:in onstart command ..."); super.onStart(intent, startid); int res; String LOG_TAG = ""; int input2 = intent.getIntExtra("input", -1); int mode = intent.getIntExtra("mode", -1); String aString = Integer.toString(mode); Log.v(LOG_TAG, aString); if(mode == 1) { res = cal_F(input2); } else { res = cal_C(input2); } intent.putExtra("result", res); } } </code></pre> # <pre><code>public class ClassExamplesServiceActivity extends Activity implements OnClickListener{ @Override public void onClick(View v) { input = Integer.parseInt(input1.getText().toString()); if(v.getId() == R.id.radio_fib) rd_button = 0; else if(v.getId() == R.id.radio_fact) rd_button = 1; else if (v.getId() == R.id.button1){ intent = new Intent(this, SimpleService.class); intent.putExtra("input", input); intent.putExtra("mode", rd_button); doBindService(); System.out.println("in class activity "+System.currentTimeMillis()); } else if(v.getId() == R.id.stop) { stopService(intent); } } private ServiceConnection mConnection = new ServiceConnection() { public void onServiceConnected(ComponentName className, IBinder service) { System.out.println("\n in service connection"); mBoundService = ((SimpleService.LocalBinder)service).getService(); } public void onServiceDisconnected(ComponentName className) { System.out.println("\n in service disconnected"); mBoundService = null; } }; void doBindService() { System.out.println("in do bind service"); boolean isConnected = bindService(new Intent(ClassExamplesServiceActivity.this, SimpleService.class), mConnection, Context.BIND_AUTO_CREATE); intent.putExtra("input", input); intent.putExtra("mode", rd_button); System.out.println("\n isconnected = "+ isConnected); mIsBound = true; } void doUnbindService() { if (mIsBound) { res = intent.getIntExtra("result", -1); result.setText(Integer.toString(res));// Set the result in the EditText // Detach our existing connection. unbindService(mConnection); mIsBound = false; } } @Override protected void onDestroy() { super.onDestroy(); doUnbindService(); } } </code></pre> # <pre><code>&lt;application android:icon="@drawable/ic_launcher" android:label="@string/app_name" &gt; &lt;activity android:label="@string/app_name" android:name=".ClassExamplesServiceActivity" &gt; &lt;intent-filter &gt; &lt;action android:name="android.intent.action.MAIN" /&gt; &lt;category android:name="android.intent.category.LAUNCHER" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;service android:name=".SimpleService"&gt;&lt;/service&gt; &lt;/application&gt; </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.
