I'm working on Ionic/Cordova, I added this to androidManifest.xml but this didn't work for me and app is still showing in both ways

android:screenOrientation="portrait"

How can I restrict my app to portrait mode only? I have checked on android and it doesn't work

Answer 1

Ionic v2+ Update

For Ionic versions 2 and later, you will need to also install the corresponding Ionic Native package for any plugin you use, including cordova-plugin- and phonegap-plugin- plugins.

1. Install Ionic Native Plugin

   Install Ionic Native's TypeScript module for the plugin from the CLI.

   $ ionic cordova plugin add --save cordova-plugin-screen-orientation
   $ npm install --save @ionic-native/screen-orientation
   

   * Note that the --save command is optional and can be omitted if you do not wish to add the plugin to your package.json file

2. Import ScreenOrientation Plugin

   Import plugin into your controller, more details available in the documentation.

   import { ScreenOrientation } from '@ionic-native/screen-orientation';
   
   @Component({
       templateUrl: 'app.html',
       providers: [
           ScreenOrientation
       ]
   })
   
   constructor(private screenOrientation: ScreenOrientation) {
     // Your code here...
   }
   

3. Do Your Thing

   Lock and unlock the screen orientation programatically.

   // Set orientation to portrait
   this.screenOrientation.lock(this.screenOrientation.ORIENTATIONS.PORTRAIT);
   
   // Disable orientation lock
   this.screenOrientation.unlock();
   

4. Bonus Points

   You can also get the current orientation.

   // Get current orientation
   console.log(this.screenOrientation.type);  // Will return landscape" or "portrait"
   

Answer 2

If you want to restrict to portrait mode only on all devices you should add this line to the config.xml in your projects root folder.

<preference name="orientation" value="portrait" />

After that, please rebuild the platform by typing below text in command line:

ionic build
