我目前正在开发一个 Android应用程序,它使用Eclipse(Java)通过蓝牙连接到设备.目前我在Android 4.4(Kit-Kat)及以下版本上工作,但在Android 5(Lollipop)的新更新之后.发生安全异常.

表现：

<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.BLUETOOTH_PRIVILEGED" />
<uses-feature android:name="android.hardware.bluetooth_le"
        android:required="false" />

码：

mBleScanner.startScan(filters,scanSettings,mLeScanCallback);

private ScanCallback mLeScanCallback = new ScanCallback()
{
    @Override
    public void onScanResult(int callbackType,ScanResult result)
    {
        BluetoothDevice device = result.getDevice();
        if(device.getName() != null)
        {
            if(device.getName().toUpperCase().contains("MyDevice"))
            {

                mBleScanner.stopScan(mLeScanCallback);

                if (device.getBondState() == BluetoothDevice.BOND_BONDED)
                {
                    Connect(device.getAddress().toString()); 
                }
                else
                {
                    // pair device
                    device.setPairingConfirmation(true);
                    device.createBond();
                }
            }
        }
    }
};
...
..
.
private void BondDevice(BluetoothGattCharacteristic bgc,boolean pnEnable)
{
    boolean bool = gatt.setCharacteristicNotification(bgc,true); // this line throw security exception
    BluetoothGattDescriptor bgd=bgc.getDescriptor(UUID.fromString(BLE_DESCRIPTOR_NOTIFY));

    byte[] arrayOfByte = pnEnable ? BluetoothGattDescriptor.ENABLE_NOTIFICATION_VALUE:
                      BluetoothGattDescriptor.DISABLE_NOTIFICATION_VALUE;
    gattDescriptor.setValue(arrayOfByte);
    mBluetoothGatt.writeDescriptor(bgd);
}
