java – Disable screen rotation in android

Question:

I am developing an android application and I don't want the screen to be rotated.

How do I disable the screen rotation option in android so that when the phone is rotated it stays vertical?

Answer:

You can do this with the screenOrientation property within your AndroidManifest.xml .

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

Another option, which involves adding code for each activity, is:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

It is added immediately after onCreate() :

@Override
protected void onCreate(Bundle savedInstanceState) {
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    super.onCreate(savedInstanceState);

...
...
...

There is currently no way to disable rotation for the entire application. As a "global" solution you could extend all your Activities from a "Parent Activity" that has defined:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
