  1. PO"requestFeature() must be called before adding content" master detail template
    text
    copied!<p>I started a new app with the master detail template.</p> <p>When I try the app on my tablet, using the two-pane layout, it crashes with the exception in the title when I change orientation of the tablet. This happens only if the detail fragment has content.</p> <p>The crash is in <code>super.onCreate</code> line, I'm not even calling <code>requestFeature</code>, so it's not even my code:</p> <pre><code>@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_item_list); if (findViewById(R.id.item_detail_container) != null) { // The detail container view will be present only in the // large-screen layouts (res/values-large and // res/values-sw600dp). If this view is present, then the // activity should be in two-pane mode. mTwoPane = true; // In two-pane mode, list items should be given the // 'activated' state when touched. ((ItemListFragment) getSupportFragmentManager().findFragmentById( R.id.item_list)).setActivateOnItemClick(true); } } </code></pre> <p>Stack trace:</p> <pre><code> 12-14 23:18:44.716: E/AndroidRuntime(32065): FATAL EXCEPTION: main 12-14 23:18:44.716: E/AndroidRuntime(32065): Process: com.manor.barcam, PID: 32065 12-14 23:18:44.716: E/AndroidRuntime(32065): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.manor.barcam/com.manor.barcam.ItemListActivity}: android.util.AndroidRuntimeException: requestFeature() must be called before adding content 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2195) 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2245) 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.app.ActivityThread.handleRelaunchActivity(ActivityThread.java:3738) 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.app.ActivityThread.access$900(ActivityThread.java:135) 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1202) 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.os.Handler.dispatchMessage(Handler.java:102) 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.os.Looper.loop(Looper.java:136) 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.app.ActivityThread.main(ActivityThread.java:5017) 12-14 23:18:44.716: E/AndroidRuntime(32065): at java.lang.reflect.Method.invokeNative(Native Method) 12-14 23:18:44.716: E/AndroidRuntime(32065): at java.lang.reflect.Method.invoke(Method.java:515) 12-14 23:18:44.716: E/AndroidRuntime(32065): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:779) 12-14 23:18:44.716: E/AndroidRuntime(32065): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:595) 12-14 23:18:44.716: E/AndroidRuntime(32065): at dalvik.system.NativeStart.main(Native Method) 12-14 23:18:44.716: E/AndroidRuntime(32065): Caused by: android.util.AndroidRuntimeException: requestFeature() must be called before adding content 12-14 23:18:44.716: E/AndroidRuntime(32065): at com.android.internal.policy.impl.PhoneWindow.requestFeature(PhoneWindow.java:249) 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.app.Activity.requestWindowFeature(Activity.java:3298) 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.support.v7.app.ActionBarActivityDelegateICS.onCreate(ActionBarActivityDelegateICS.java:63) 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.support.v7.app.ActionBarActivity.onCreate(ActionBarActivity.java:98) 12-14 23:18:44.716: E/AndroidRuntime(32065): at com.manor.barcam.ItemListActivity.onCreate(ItemListActivity.java:54) 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.app.Activity.performCreate(Activity.java:5231) 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1087) 12-14 23:18:44.716: E/AndroidRuntime(32065): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2159) 12-14 23:18:44.716: E/AndroidRuntime(32065): ... 12 more </code></pre> <p>How can I solve it?</p> <p>Thanks.</p>
