How to Lock Android App's Orientation to Portrait in Phones and Landscape in Tablets?

Question

I am developing an Android app whose orientation I don't want changed to landscape mode when the user rotates the device. Also, I want the locked orientation to be portrait mode on phones and landscape mode on tablets. Can this be achieved, if yes how? Thanks.

Answer 1

You just have to define the property below inside the activity element in your AndroidManifest.xml file. It will restrict your orientation to portrait.

android:screenOrientation="portrait"

Example:

        <activity
            android:name="com.example.demo_spinner.MainActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait" >
        </activity>

if you want this to apply to the whole app define the property below inside the application tag like so:

        <application>
         android:screenOrientation="sensorPortrait"
        </application>

Additionaly, as per Eduard Luca's comment below, you can also use screenOrientation="sensorPortrait" if you want to enable rotation by 180 degrees.

Answer 2

You have to add the android:screenOrientation="portrait" directive in your AndroidManifest.xml. This is to be done in your <activity> tag.

In addition, the Android Developers guide states that :

[...] you should also explicitly declare that your application requires either portrait or landscape orientation with the element. For example, <uses-feature android:name="android.hardware.screen.portrait" />.

Answer 3

I can see you have accepted an answer which doesn't solve your problem entirely:

android:screenOrientation="portrait" 

This will force your app to be portrait on both phones and tablets.

You can have the app forced in the device's "preferred" orientation by using

android:screenOrientation="nosensor"

This will lead to forcing your app to portrait on most phones phones and landscape on tablets. There are many phones with keypads which were designed for landscape mode. Forcing your app to portrait can make it almost unusable on such devices. Android is recently migrating to other types of devices as well. It is best to just let the device choose the preferred orientation.

Answer 4

It might be.. you have to identify it is tablet or phone by programmatically... First check device is phone or tablet

Determine if the device is a smartphone or tablet?

Tablet or Phone - Android

Then......

if(isTablet)
{
      setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);      
}else
{
      setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

Answer 5

<activity android:name=".yourActivity"
          android:screenOrientation="portrait" ... />

add to main activity and add

android:configChanges="keyboardHidden"

to keep your program from changing mode when keyboard is called.

Answer 6

Set the Screen orientation to portrait in Manifest file under the activity Tag.

Answer 7

android:screenOrientation="locked"

in <application> for all app in <activity> for actual activity

Answer 8

Set the Screen orientation to portrait in Manifest file under the activity Tag.

Here the example

You need to enter in every Activity

Add The Following Lines in Activity

for portrait

android:screenOrientation="portrait"
tools:ignore="LockedOrientationActivity"

for landscape

android:screenOrientation="landscape"
tools:ignore="LockedOrientationActivity"

Here The Example of MainActivity

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="org.thcb.app">
 
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

        <activity android:name=".MainActivity"
            android:screenOrientation="portrait"
            tools:ignore="LockedOrientationActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

<activity android:name=".MainActivity2"
            android:screenOrientation="landscape"
            tools:ignore="LockedOrientationActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Just Add:

android:name=".MainActivity"
android:label="@string/app_name">
</activity>
