<a href="http://www.codingforandroid.com/2011/01/using-orientation-sensors-simple.html" rel="nofollow noreferrer">Here's a link</a> to a blog with a solution. Essentially, you stop using the Orientation Sensor and use the Magnetic Field Sensor and Accelerometer Sensor(s) in tandem to get equivalent functionality. It's more work but it does allow you to continue to use a callback to handle orientation changes.

Hello I want to use the type <code>type_orientation</code> but it is deprecated for the android 4.0.3 . I use it for the augmented reality. I tried to find on the net but without success. My application works but my text inside stay in the same place! Here my code:

<pre><code> @Override
 protected void onStart() { 
 super.onStart();
 sensorMngr = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
 sensorLstr = createListener();
 sensorMngr.registerListener(sensorLstr, sensorMngr.getDefaultSensor(Sensor.TYPE_ORIENTATION), SensorManager.SENSOR_DELAY_UI);
 }

 @Override
 protected void onStop() { 
 super.onStop();
 sensorMngr = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
 sensorMngr.unregisterListener(sensorLstr, sensorMngr.getDefaultSensor(Sensor.TYPE_ORIENTATION)); 
 }
</code></pre>

Everything it s good just this, i looked already on <a href="http://developer.android.com/reference/android/hardware/Sensor.html">http://developer.android.com/reference/android/hardware/Sensor.html</a>, but i can t understand (I m french and my english is not very perfect...) Thank you very much for your help!!!

How can i replace type_orientation (is deprecated) for android 4.0.3?

增强现实

您好，我想使用类型type_orientation，但它在Android4.0.3中已被弃用。我将其用于增强现实。我试着在网上找，但没有成功。我的应用程序可以工作，但我的文本留在相同的地方！下面是我的代码： @Override    protected void onStart() {              sup...
