copied!<p>The <a href="http://developer.android.com/reference/android/view/Display.html#getRealSize%28android.graphics.Point%29" rel="nofollow">Display.getRealSize()</a> method was added in API 17, which is Android 4.2. If you try to use it on a device below that, you will get a NoSuchMethodException as the method doesn't exist.</p> <p><a href="http://developer.android.com/reference/android/view/Display.html#getSize%28android.graphics.Point%29" rel="nofollow">Display.getSize()</a> was added in API 13, which is Android 3.2. You want to use the app on Android 3.0, which is API 11.</p> <p>So for older devices, and even current ones (I am yet to hear of a deprecated method actually being removed from Android), you should use <a href="http://developer.android.com/reference/android/view/Display.html#getWidth%28%29" rel="nofollow">getWidth()</a> and <a href="http://developer.android.com/reference/android/view/Display.html#getHeight%28%29" rel="nofollow">getHeight()</a>.</p> <p>Or you could run the code in an if else statement, something like:</p> <pre><code>int currentapiVersion = android.os.Build.VERSION.SDK_INT; if (currentapiVersion >= android.os.Build.VERSION_CODES.JELLY_BEAN_MR1){ //Do something for API 17 only (4.2) //getRealSize() } else if (currentapiVersion >= android.os.Build.VERSION_CODES.HONEYCOMB_MR2){ // Do something for API 13 and above , but below API 17 (API 17 will trigger the above block //getSize() } else{ // do something for phones running an SDK before Android 3.2 (API 13) //getWidth(), getHeight() } </code></pre>
