Disabling multi-touch on my app

Question

For some reasons I have to disable the multi-touch feature on my app. The user can press only one button at a time, or the app would crash. Is there any way to implement this requirement?

Thanks a lot!

To prevent this you should turn off splitMotionEvents or windowEnableSplitTouch attribute inside ViewGroup were buttons are located.

android:splitMotionEvents="false"

So what happens if an app has a deep view hierarchy and there are buttons at the leaf nodes of the hierarchy? We need to mark every ViewGroup up to the root with this attribute? – satur9nine Mar 12 '14 at 01:41
Yes you are right, second approach is to create custom view group and override `onTouchEvent` there. Example is here: http://goo.gl/pRXtCk – Dmytro Danylyk Mar 12 '14 at 07:33

add this line to your manifest

< uses-feature android:name="android.hardware.touchscreen.multitouch" android:required="false" />

I don't think that a tag will disable a feature.. See this: http://developer.android.com/guide/topics/manifest/uses-feature-element.html – Christian Brüggemann Jul 09 '12 at 09:59
