I just tried installing BluetoothLeGatt sample from (http://developer.android.com/samples/BluetoothLeGatt/project.html) on my Nexus 7 2013 with Android 4.4.2 and it always fails to start saying "Unfortunately, BluetoothLeGatt has stopped"

Following is error logs:

  • Can you upload the error logs ? – Lucifer Feb 20 '14 at 09:53
  • Hi, please find the error log on following url within brackets [https://docs.google.com/document/d/1DBQ3t58zJoYgMw_U7MmuDk8CjfXa9VxgPjQQCpo1Mew/edit?usp=sharing] thanks. – user3332037 Feb 20 '14 at 11:45
  • You have not got the project setup properly if you really have copied everything. It's failing to fine the DeviceScanActivity. Is it in the manifest? – Ifor Feb 20 '14 at 15:30
  • Yes its in the manifest, I can side load the app to the device without any problem, the problem is it gives me "Unfortunately, BluetoothLeGatt has stopped" every time when I run it on the device – user3332037 Feb 24 '14 at 04:00
  • and I think there is some thing to do with dalvik and ART, please have a look at following error log. https://docs.google.com/document/d/1123A83DAS8A5odfsat36S7hQvWURJHvTtV7OJyPWIOg/edit?usp=sharing Thanks – user3332037 Feb 24 '14 at 04:04

Not sure if you figured this out already, but I had the same issue. The samples are based on Android Studio not Eclipse+ADT. If you install the latest version of Android Studio and then import the sample project it will run on the device, and I was able to detect peripheral devices.
