I have tried every method to lock the screen to portrait orientation but they simply do not work after testing the app via Adobe PhoneGap Build.
Firstly, I have modified the MainActivity.java file to include at onCreate
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
Secondly, I have modified the config.xml file to include
<preference name="orientation" value="portrait" />
Thirdly, I have modified the Manifest file to include
android:screenOrientation="portrait"
None of the above are working.
Update the config.xml File which is in your project folder, above www.
Add the line:-
<preference name="orientation" value="portrait" />
Then build you project & there will be no Orientation Change.
In place of "portrait" you can use "landscape".
