Intent startNewActivityOpen2 = new Intent(this, TransitionLandscape.class);
if (extras != null) {
if (!extras.isEmpty()) {
startNewActivityOpen2.putExtras(extras);
}
}
startActivity(startNewActivityOpen2);
这个当前活动是否也是TransistionLandscape.class是否重要？当我开始新活动时,应用程序会退出(不会崩溃).通过调试器,永远不会调用新活动:(永远不会调用onCreate in)

另外,致电：
recreate()
而不是去新的活动,也导致应用程序退出(没有崩溃).
编辑：清单
<activity
android:name=".TransitionLandscape"
android:configChanges="orientation"
android:label="@string/app_name"
android:launchMode="singleTask"
android:screenorientation="landscape"
android:windowSoftInputMode="stateHidden">
</activity>
实际上,我在TransitionLandscape之后调用的任何活动都会导致应用程序退出.这是记忆问题吗？
解决方法:
在收到配置更改后,您的应用程序在该意图后崩溃.

你能试试吗？
android:configChanges="orientation|screenSize|keyboardHidden" />
