首先是先实例化:
bleManager = new BleManager(mContext);
然后进来:
public BleManager(Context context) {
this.mContext = context;

    if (bleBluetooth == null) {
        bleBluetooth = new BleBluetooth(context);
    }

    bleExceptionHandler = new DefaultBleExceptionHandler(context);

}

其中 bleBluetooth = new BleBluetooth(context);这一句里面有个回调的全局变量coreGattCallback,
coreGattCallback = new BleGattCallback(),而BleGattCallback是继承自BluetoothGattCallback的,然而我用android4.1.1的设备测试的时候,实例化就直接崩溃,所以:
if( bleManager.isSupportBle() ){

}
这一句走不到这里来

建议在使用库之前,自主判断Android版本
