Press power button to lock the phone, then the running apk quit.

I have found that when we release a apk using unity3D purely, and there's no Plugins/Android , the apk works well when the user lock the phone and resume .The game resumed as we expected.
But when I export the project to eclipse and build the apk as the official document :
http://unity3d.com/support/documentation/Manual/Android-Integrating Unity With Eclipse.html
Now the bug happens when the user press power button and lock the phone while playing , the running apk quit. And if the user unlock the phone, the apk start all over again.
And I notice if I write a plugin and place it under Plugins/Android , the bug happens too.
So I guess is there any bug in the UnityPlayerActivity or someother things.
I don't know if anyone have had my problem, sorry for my English. Thanks for any help. :-|

 

hi ,guys , i have tried test the whole process a again and again. I think i can locate the bug now. A just clean and empty project ,If we build a "portrait" apk, and integrate it in eclipse, that apk work well on the lock button problem.
But if you build a "landscape" apk , and modify the AndroidManifest.xml to the start Activity "android:screenOrientation="landscape",
that bug happen!

the only log is "Unity onDetachedFromWindow" , when the power button is pressed, then the whole app quit

 

I have solved the problem now, what should do is to modify the AndroidManifext.xml ,and add the line :
android:configChanges="keyboard|keyboardHidden|orientation"
in Activity.
Thanks for help.Hope this would help someone else.

 

You should always use the most recent AndroidManifest.xml available in the Unity folder. On Windows it can be found in C:\Program Files (x86)\Unity\Editor\Data\PlaybackEngines\androidplayer

The current version as of Unity3D 3.5

As you see, the configChanges have a lot more parameters, than yours above.

PHP:

fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen

Some of this are new and for Tablets and/or the new Android 4.0 devices (i.e. screenSize and smallestScreenSize being new added with API Level 13

Ah great, this helped solve my problem too. Thanks Tseng. Although I had trouble finding this thread in a search because I was using the term sleep and power, rather than lock. So hopefully my using it now might help other searches in the future!

 

Thank you so much, ZoMask and Tseng! Was running into similar problems with sliding an Xperia Play open and shut...
