file： BluetoothEventLoop.java GB/GB2/GB3: 1. import android.os.PowerManager; 2. 变量申明：private PowerManager.WakeLock mWakeLock; 3. BluetoothEventLoop(){} 构造函数里面添加定义： PowerManager pm = (PowerManager)context.getSystemService(Context.POWER_SERVICE); mWakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE, TAG); mWakeLock.setReferenceCounted(false); 4. onRequestPairingConsent(){ ... mWakeLock.acquire(5000); // xintong , 亮屏5s Intent intent = new Intent(BluetoothDevice.ACTION_PAIRING_REQUEST); ... } 5. onRequestPasskeyConfirmation(){ ... mWakeLock.acquire(5000); // xintong , 亮屏5s Intent intent = new Intent(BluetoothDevice.ACTION_PAIRING_REQUEST); ... } 6. onRequestPasskey(){ ... mWakeLock.acquire(5000); // xintong , 亮屏5s Intent intent = new Intent(BluetoothDevice.ACTION_PAIRING_REQUEST); ... } 7. onRequestPinCode(){ ... mWakeLock.acquire(5000); // xintong 亮屏5s Intent intent = new Intent(BluetoothDevice.ACTION_PAIRING_REQUEST); ... } 8. onDisplayPasskey(){ ... mWakeLock.acquire(5000); // xintong , 亮屏5s Intent intent = new Intent(BluetoothDevice.ACTION_PAIRING_REQUEST); ... } ICS/ICS2/JB/JB2/JB3: 省略掉GB中修改的第1、2、3步； 对4、5、6、7、8中修改的function中：将原生的mWakeLock.acquire(); 改为mWakeLock.acquire(5000)， 删掉对应function中的mWakeLock.release(); 修改完后，模块会被编译进framework.jar
