我只是試圖從（http://developer.android.com/samples/BluetoothLeGatt/project.html）在我的Nexus 7 2013安裝BluetoothLeGatt樣品用的是Android 4.4.2，它始終無法啓動，說：「不幸的是，BluetoothLeGatt已停止」藍牙低耗能的Android exsample不起作用

你可以上傳錯誤日誌嗎？ – Kedarnath
嗨，請在括號[https://docs.google.com/document/d/1DBQ3t58zJoYgMw_U7MmuDk8CjfXa9VxgPjQQCpo1Mew/edit?usp=sharing]謝謝以下網址找到錯誤日誌。 – user3332037
