How to restrict app to portrait mode only in ionic for all platforms?

ionic-framework

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

Solution 1:

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

Solution 2:

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.

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

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...
}

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();

Bonus Points

You can also get the current orientation.

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

Solution 3:

According to https://cordova.apache.org/docs/en/4.0.0/config_ref/#global-preferences,

Orientation allows you to lock orientation and prevent the interface from rotating in response to changes in orientation. Possible values are default, landscape, or portrait. Example:

<preference name="Orientation" value="landscape" />

Be aware that these values are case sensitive, it is "Orientation", not "orientation".

Solution 4:

If you want to do something on your orientation means you want to perform any action when change your app orientation then you have to use ionic framework plugin... https://ionicframework.com/docs/native/screen-orientation/

If you just want to restrict your app on portrait or landscape mode then you have to just add these following line in your config.xml

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