How to Use Onconfigurationchanged() and Newconfig.Orientation == Configuration.Orientation_Landscape in Android 2.3.3

How to use onConfigurationChanged() and newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE in android 2.3.3

Just write the below code into onConfigurationChanged method and test

if(newConfig.orientation==Configuration.ORIENTATION_LANDSCAPE){

    Log.e("On Config Change","LANDSCAPE");
}else{

    Log.e("On Config Change","PORTRAIT");
}

and write the android:configChanges="keyboardHidden|orientation" into your manifiest file like this

<activity android:name="TestActivity"
           android:configChanges="keyboardHidden|orientation">

it's working at my side, i hope it helps you.

If you're on tablet also add |screenSize to android:configChanges

Android 2.3.3 & 4.1.2 android:configChanges for detecting Orientation change

Hi Look at mine AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="10" 
    android:maxSdkVersion="16"/>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity 
        android:name=".ConfigrationTask"
        android:configChanges="orientation|keyboardHidden"
        >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>

    </activity>
</application>

orientation is not working in 2.3.3?

You might be hitting this bug "Orientation does not change from landscape to portrait on Emulator on 2.3"

More than 45 people are facing the same issue with the androidd 2.3 emulator

http://code.google.com/p/android/issues/detail?id=13189

Host OS: Windows 7 SDK tools version : revision 8 Eclipse version: 3.5
ADT plug-in version: 8.0.1 Platform targeted by your project: 2.3
Version of the platform running in the emulator:2.3

STEPS TO REPRODUCE:
1. Activity 1 (no screen orientation) - Activity 2 (screen orientation = landscape)

1. Going from Activity 1 to 2 works fine. Pressing back changes the orientation of Activity 1 to landscape

EXPECTED RESULTS: Activity 1 should be in portrait mode

OBSERVED RESULTS: Behavior is observed only in gingerbread, works as
expected on froyo.

How is orientation change handled in the message queue?

Yes, it is atomic operation.

in pseudo it looks like:

void setNewOrientation(int state) {
    currentState = state;
    runOrientationChangedEvent();
}

And then usually Activity is re-created. Only re-creating of Activity adds to the message queue, so it is possible to see if change device orientation fast enough.

You cannot get start and end of this process, because it just changes a few int variables which can tell you about current orientation like orientation:

getActivity().getResources().getConfiguration().orientation

or rotation

getWindowManager().getDefaultDisplay().getRotation();

So you can get event only after orientation is changed.

Android onConfigurationChanged not being called

A couple of things to try:

android:configChanges="orientation|keyboardHidden|screenSize" rather than android:configChanges="orientation"

Ensure that you are not calling setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); anywhere. This will cause onConfigurationChange() to not fire.

Check that you are not using android:screenOrientation in your manifest.

If none of that works, read through the Android doc on handling runtime changes and make sure you are doing everything correctly. There may be something somewhere else in your code that's causing the problem. http://developer.android.com/guide/topics/resources/runtime-changes.html

EDIT: As derrik pointed out, I assumed that you were changing the configuration with the accelerometer detecting what way the device was facing. If you want the configuration to change as the keyboard is shown/hidden the configChanges in the manifest must include keyboardHidden as well.

How to detect orientation change in layout in Android?

Use the onConfigurationChanged method of Activity.
See the following code:

@Override
public void onConfigurationChanged(@NotNull Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    // Checks the orientation of the screen
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
        Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
    }
}

You also have to edit the appropriate element in your manifest file to include the android:configChanges
Just see the code below:

<activity android:name=".MyActivity"
          android:configChanges="orientation|keyboardHidden"
          android:label="@string/app_name">

NOTE: with Android 3.2 (API level 13) or higher, the "screen size" also changes when the device switches between portrait and landscape orientation. Thus, if you want to prevent runtime restarts due to orientation change when developing for API level 13 or higher, you must declare android:configChanges="orientation|screenSize" for API level 13 or higher.

Hope this will help you... :)

Check orientation on Android phone

The current configuration, as used to determine which resources to retrieve, is available from the Resources' Configuration object:

getResources().getConfiguration().orientation;

You can check for orientation by looking at its value:

int orientation = getResources().getConfiguration().orientation;
if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
    // In landscape
} else {
    // In portrait
}

More information can be found in the Android Developer.
