Unable to lock orientation ; possible fix?

Question

Trying to set orientation to Portrait only by default. To make it so, I've added:

android:configChanges="orientation"
android:screenOrientation="portrait"

However, the app auto rotates to Landscape mode when tilted. Furthermore, the app turns to Landscape mode when tilted even when the orientation is locked to portrait only in phone Settings .

Here is the Manifest.xml file :

What could possibly be causing this and how to fix this issue?

Answer 1

Add screenOrientation = "portrait" to each activity, like so:

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

Make sure your Java code does not alter the activity's orientation by accident. Configchanges doesn't set it to default, it asks the Java to be in charge of setting it. Remove those if they don't do anything else. See android docs here (search for "android:configChanges")
