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.

Answer 1

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.
