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

Answer 1

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>

Answer 2

<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 3

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