Question

我正在尝试为服务实现唤醒锁定和wifi锁定。有关我的方案的更多信息，请参阅：Wakelock implementation in a service。我在启动时获取并在服务被破坏时释放。我想监控我的项目的电池消耗，虽然我明白，这种方法并不好。但是当我的手机屏幕关闭时，它无法正常工作。我启用了选项：在睡眠期间保持Wifi开启。一旦我的屏幕关闭，我的服务就会停止。我正在使用片段：

PowerManager powerManager = (PowerManager)getSystemService(Context.POWER_SERVICE);
wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My Lock");
if(!wakeLock.isHeld())
{
wakeLock.acquire();
}
Log.d(TAG,"Acquired Wake lock successfully");
wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
wifiLock = wifiManager.createWifiLock(WifiManager.WIFI_MODE_FULL_HIGH_PERF , "WiFi LockTag");
if(!wifiLock.isHeld())
{
wifiLock.acquire();
}
Log.d(TAG,"Acquired Wifi lock successfully");

//发布

try{
wifiLock.release(); 
}catch(Exception e){
e.printStackTrace();
Log.d(TAG,"Exception while releasing WakeLock :: Can be ignoredd");
}

知道为什么会这样吗？提前谢谢！

保护屏幕免受锁定使用此Spinet

public static void unlockTheScreen(Context context) {
    KeyguardManager keyguardManager = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE); 
    KeyguardLock keyguardLock =  keyguardManager.newKeyguardLock("TAG");
    keyguardLock.disableKeyguard();     
}

在唤醒锁中添加以下内容

  wakeLock = powermanager.newWakeLock((PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP ), "TAG");

屏幕关闭时，Android Wakelock无法正常工作
