PhoneGap - Forcing Landscape orientation

Have you tried this?

android:screenOrientation="portrait"

Inside the AndroidManifest.xml file, where you have declared your activity, just add the above line.

For example:

<activity            android:name=".Activity.SplashScreenActivity"            android:label="@string/app_name"            android:screenOrientation="portrait">            <intent-filter>                <action                    android:name="android.intent.action.MAIN" />                <category                    android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>

The correct way to do this for all devices is to configure config.xml

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

It is very simple, you need to add android:screenOrientation="landscape" in your AndroidManifest.xml file.

<application android:icon="@drawable/icon" android:label="@string/app_name">    <activity android:name=".LogUploaderActivity" android:label="Log Uploader" android:screenOrientation="landscape" >        <intent-filter>            <action android:name="android.intent.action.MAIN" />            <category android:name="android.intent.category.LAUNCHER" />        </intent-filter>    </activity>
