bluetooth keyboard will cause activity destroy and recreate

Question

Bluetooth keyboard will cause activity destroy and recreate if I turn off it or far away from pad(Android) Activity will be recreate how can i avoid this problem

Answer 1

Pairing a Bluetooth keyboard is considered to be a configuration change: Try adding the below to your AndroidManifest.xml

android:configChanges="keyboard|keyboardHidden"

From: http://developer.android.com/guide/topics/manifest/activity-element.html#config android:configChanges

Answer 2

In contrast to the accepted answer, I found that keyboard|keyboardHidden was not enough. I was working with a Logitech Bluetooth keyboard (model #JNZYR0021).

What did work was this:

<activity
  ...
  android:configChanges="orientation|screenSize|keyboard|keyboardHidden|navigation"
/>

Apparently this Logitech keyboard also changes navigation, which is weird because the Android docs say:

The navigation type (trackball/dpad) has changed. (This should never normally happen.)

Go figure.
