    <p>I have an activity which basically sleeps for a time and initialize another activity. During this sleep time I make some animated drawings on screen.</p> <pre><code>public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN); View splashScreen = new SplashScreenView(this); setContentView(splashScreen); Thread splashThread = new Thread(){ public void run(){ try{ sleep(6500); startActivity(new Intent("com.example.LOGIN")); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } finally{ finish(); } } }; splashThread.start(); } </code></pre> <p>But when the screen orientation changes, the activity was restarting. So I handled it by modifying manifest file.</p> <pre><code>&lt;activity android:name=".SplashScreenActivity" android:configChanges="orientation|keyboardHidden" android:label="@string/app_name" &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; </code></pre> <p>I have one problem left. I prevent activity from restarting but the onDraw() function in my SplashScreenView class still restarts.</p> <pre><code>protected void onDraw(Canvas canvas) { canvas.drawBitmap(dstbmp2, logoX, logoY, null); canvas.drawBitmap(dstbmp, ballX, ballY, null); // Update the position of the ball. update(); // Delay try { Thread.sleep(100); } catch (InterruptedException e) { } invalidate(); } </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.
