    <p>I have tried different ways to get the screen size of the device, but it always returned me the wrong size (791x480 instead of 854x480), it might be due to the navigation bar. My device is currently running JellyBean 4.1.1.</p> <p>I tried :</p> <pre><code>Display display = getWindowManager().getDefaultDisplay(); Point size = new Point(); display.getSize(size); OpenGLRenderer.widthScreen = size.x; OpenGLRenderer.heightScreen = size.y; </code></pre> <p>And :</p> <pre><code>DisplayMetrics dm = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(dm); String resolution = dm.widthPixels + "x" + dm.heightPixels; </code></pre> <p>I'm using the following code to make the app full screen:</p> <pre><code>setContentView(mGLSurfaceView); mGLSurfaceView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION); </code></pre> <p>I noticed that in the logcat the right size is returned :</p> <pre><code>01-01 03:05:06.967: I/InputReader(1961): Device reconfigured: id=8, name='cyttsp-spi', surface size is now 480x854, mode is 1 </code></pre> <p>In my AndroidManifest :</p> <pre><code>uses-sdk android:minSdkVersion="8" android:targetSdkVersion="16" </code></pre> <p>I used:</p> <ul> <li><a href="https://stackoverflow.com/questions/8566322/get-the-real-screen-resolution-on-ice-cream-sandwich">Get the real screen resolution on Ice Cream Sandwich</a></li> <li><a href="https://stackoverflow.com/questions/11824193/htc-sensation-real-resolution">HTC Sensation Real Resolution</a></li> <li><a href="https://stackoverflow.com/questions/1016896/android-how-to-get-screen-dimensions">Get screen dimensions in pixels</a></li> </ul> <p>Why am I not able to get the real size (<code>480x854</code>) ? Or how can I use the surface returned by the “Device reconfigured” ?</p>

    2. COI'm confused. You're asking how to get the physical size of the device, then you say you get the size minus the navigation bar. Then you say you have the physical size of the device. Where's your problem exactly?

    3. CO@deev You’re right, I’m asking how to get the physical size of the device, I just suppose that the size returned to me is the one minus the nav bar. I’m asking for a way to write a code wich will give the physical size for any device.

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.
