Force "portrait" orientation mode


Question

I'm trying to force the "portrait" mode for my application because my application is absolutely not designed for the "landscape" mode.

After reading some forums, I added these lines in my manifest file:

<application 
  android:debuggable="true"
  android:icon="@drawable/icon" 
  android:label="@string/app_name"
  android:screenOrientation="portrait">

But it doesn't work on my device (HTC Desire). It switches from "portrait" lo "landscape", ignoring the lines from the manifest file.

After more forums reading, I tried to add this in my manifest file:

<application 
  android:debuggable="true"
  android:icon="@drawable/icon" 
  android:label="@string/app_name"
  android:configChanges="orientation"       
  android:screenOrientation="portrait">

and this function in my activity class:

public void onConfigurationChanged(Configuration newConfig)
{
    super.onConfigurationChanged(newConfig);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

But again, no luck.

Accepted Answer

Don't apply the orientation to the application element, instead you should apply the attribute to the activity element, and you must also set configChanges as noted below.

Example:

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

This is applied in the manifest file AndroidManifest.xml.

Note that

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

is added in the manifest file - where the activity is defined.
