I have published a new update of my App. After publishing it got a warning like “Warning: Your active APK supports less devices then the previous APK. Some users won’t get the update.”
So i’ve compared the details of the current and the prior APK. There is only one difference: The new one has the additional entry “Native Platform: simple-xml.2.6.9.jar”.
Do you think that there is a problem with it? Acutally i’ve intergrated the .jar into my android project.

Additionally, the developer console shows me that the app is now compatible with 0 devices… if i search for a certain device i get a notice that it’s because of my manifest settings.

if i install the apk directly on my device, it works fine.
Alright, i fixed it.
The problem was that actualy only the SurveyLib.jar is using simple-xml-2.6.9.jar and the simplexml.jar was included within the SurveyLib.jar. So i think there was a problem dexing the simplexml.jar within surveylib.jar.
i’ve created the surveylib.jar again without simplexml.jar but included the simplexml.jar to the libs folder of my app.
now it works fine. thanks to you all for your help.
