orientation

问题 I'm using React Native 0.29 and developing for Android. I'm trying to lock the device orientation. What I need is to lock the screen in portrait mode. I tried with this repository https://github.com/yamill/react-native-orientation but it is not supporting RN 0.29 yet. Is there any way I can lock the device orientation? Maybe any native Android hack with android studio? 回答1: Just add android:screenOrientation="portrait" to the activity in the AndroidManifest.xml. 回答2: There is a pull request

In time of rotation

问题 We're writing a mobile app using jQuery mobile and do most of the javascript debugging in Chrome.
