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);
}

解决方法
04-27 12:36:24.559: W/BluetoothGatt(17764): java.lang.SecurityException: Need
BLUETOOTH_PRIVILEGEDpermission: Neither user 10215 nor current process hasandroid.permission.BLUETOOTH_PRIVILEGED.
只需添加它要求的权限：
<uses-permission android:name="android.permission.BLUETOOTH_PRIVILEGED" />
