Android始终处于纵向模式不起作用

Question

I want to run my application always in portrait mode. I searched and found the code below, then I added to manifest file.

android:configChanges="orientation"
android:screenOrientation="portrait"

but my application still chancing orientation when I press CRTL+F12 on AVD. How can I force my application always run in portrait mode?

Ps: I tried the code reverse. (Second line first then first line)

Answer 1

Did you add that in the activity element, not the application element?

 <activity 
    android:screenOrientation="portrait"  
    android:configChanges="orientation|keyboardHidden" >
 </activity>
