Question

I want to fix screen orientation on my android application to portrait. Using google, i’ve found, that this can be done by adding the following code to my manifest.xml:

<activity android:name=".LauncherActivity"
  android:configChanges="keyboardHidden|orientation" 
  android:screenOrientation="portrait">
</activity>

That’s fine enough, but the problem is follows: I’ve about 15 activities now, and this number will grow. Is there any way to apply orientation to all activities at once?

I tried to use styles in a following way:

theme.xml

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
  <style name="Custom" parent="android:Theme">
    <item name="android:screenOrientation">portrait</item>
    <item name="android:windowBackground">@drawable/launcher</item>
    <item name="android:configChanges">keyboardHidden|orientation</item>
  </style>
</resources>

Manifest.xml

<application ... 
android:debuggable="true"
  android:theme="@style/Custom"
>
//...
</application>

or

<activity
... 
  android:theme="@style/Custom"
>
//...
</activity>

Both the examples apply windowBackground succesfully, but screenOrientation does’t works. Any ideas?

No way. I need to repeat

<activity android:name=".LauncherActivity"
  android:configChanges="keyboardHidden|orientation" 
  android:screenOrientation="portrait">
</activity>

in every <activity> tag in manifest.
