How is application orientation (landscape or portrait) locked?

Question

I have tried to freeze orientation using:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

Although the display stays in

Answer 1

Try this:

1.- Set the desired screen orientation in your AndroidManifest.xml

android:screenOrientation="portrait|landscape"

It should look like this:

2.- Add this to your onCreate void(or wherever you want) in your java Activity File(Example: "MainActivity.java"):

super.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LOCKED);

It should look like this:

protected void onCreate(Bundle savedInstanceState) {
    super.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LOCKED);}

Now the screen wont move even if the Screen Rotation is on in the Device.
