Android : Application does not seek into layout-land when the device changes his orientation -


I want to use layout-land subfolders to change my scenes to landscape mode. Therefore, I have created a subfolder "layout-land", copy my ideas in it and customize the layout. So I have it:

Enter image details here

Reveal me: 

  & lt; Manifest xmlns: Android = "http://schemas.android.com/apk/res/android" package = "com.test.mpaa.cameratest.app" & gt; & Lt; Use-enabled Android: name = "android.hardware.camera" /> & Lt; Usage-permission Android: name = "android.permission.ACCESS_FINE_LOCATION" /> & Lt; Usage-permission Android: name = "android.permission.INTERNET" /> & Lt; Usage-permission Android: name = "android.permission.WRITE_EXTERNAL_STORAGE" /> & Lt; Android Android: allowBackup = "true" android: icon = "@draubable / IC_Luncher" Android: label = "@ string / app_name" Android: Theme = "@ Style / Aaptim" & gt; & Lt; Activity Android: name = "com.mycompany.myapp.basic" Android: configChanges = "orientation-keyboardHidden; screen size" Android: label = "@ string / title_activity_baseass" Android: theme = "@ style / fullscreenTheme" & gt; & Lt; / Activity & gt; & Lt; Activity Android: name = "com.mycompany.myapp.loginActivity" Android: configChanges = "orientation-keyboardHidden; screenSize" Android: label = "@ string / title_activity_login" Android: Theme = "@Style / FullscreenTheme" & gt; & Lt; Intent-Filter & gt; & Lt; Action Android: name = "android.intent.action.MAIN" /> & Lt; Category android: name = "android.intent.category.LAUNCHER" /> & Lt; / Intent-Filter & gt; & Lt; / Activity & gt; & Lt; / Application & gt;   
  
 But when I start my app and rotate my device, it is always a portrait view that is displayed (in the root of the layout folder See). It seems that the Android layout does not look for ideas in the ground; the screen also revolves, but the scene is still the same.  
 Therefore, I tried to create a "layout-port" folder and remove all my ideas from the root layout folder, but crashed on the app because the compiler R.layout.activity_basic and R.layout activity_login is undefined.  
 Do I miss something ??  
 Thank you for your help.   
 
 
 OK, I got the solution if I want to manage different ideas then I  
  android: configChanges = "orientation | keyboardHidden | screenize"   
  
   android: configChanges = "| keyboardHidden | screenSize "  
 I delete" orientation "from configChanges and use the right layout folder structure and it works fine!
