How to keep screen orientation in portrait mode with Android 5.0?

Question

I need to keep the screen in portrait mode. For this I use this line in the manifest file

android:screenOrientation="portrait"

Here my file

<activity
        android:name=".activities.Splash"
        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>

I use a Samsung S5, and it still can rotate in landscape...

Accorging documentation with Android 5.0 we get wide setting options

android:screenOrientation=["unspecified" | "behind" |
"landscape" | "portrait" |
"reverseLandscape" | "reversePortrait" |
"sensorLandscape" | "sensorPortrait" |
"userLandscape" | "userPortrait" |
"sensor" | "fullSensor" | "nosensor" |
"user" | "fullUser" | "locked"]

I have tried some of them but it still rotate...

What am I doing wrong?

In your manifest file after your main activity Paste below line.

java through setContentView() Paste below line.

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

see documentation.

Can you add android:configChanges="orientation|keyboardHidden" ?

<activity
    android:name=".activities.Splash"
    android:label="@string/app_name"
    android:screenOrientation="portrait"
    android:configChanges="orientation|keyboardHidden">

Answer 4

In your manifest file after your main activity Paste below line.

android:screenOrientation="portrait"

Or in your coding after setContentView() Paste below line.

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

Locks the orientation to its current rotation, whatever that is. Added in API level 18.

android:screenOrientation="locked"

android:screenOrientation="locked"
