Question

我希望我的应用在后台运行，或者在手机进入睡眠状态后，当您接近某个纬度和经度时，我的应用会立即弹出到前台。无论是从睡眠还是其他应用程序都在前台，这都必须有效。我正在使用服务和WakeLock。我很确定该服务正在运行，但我不知道如何检查，因为如果它不在foregrond中，调试器将不返回任何内容。如果它正常工作，那么我的WakeLock没有按预期工作。

public abstract class WakeLocker {

private static PowerManager.WakeLock fullWakeLock;
private static PowerManager.WakeLock partialWakeLock;
private static PowerManager pm;

public static void acquire(Context context) {
    if (fullWakeLock != null) fullWakeLock.release();
    if (partialWakeLock != null) partialWakeLock.release();

    pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
    fullWakeLock = pm.newWakeLock((PowerManager.SCREEN_BRIGHT_WAKE_LOCK |
            PowerManager.FULL_WAKE_LOCK |
            PowerManager.ACQUIRE_CAUSES_WAKEUP), "Loneworker - FULL WAKE LOCK");
    partialWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "Loneworker - PARTIAL WAKE LOCK");
    partialWakeLock.acquire();
}

public static void release() {
    if (fullWakeLock != null) {
        fullWakeLock.release();
        fullWakeLock = null;
    }
    if (partialWakeLock != null) {
        partialWakeLock.release();
        partialWakeLock = null;
    }
}

public static void wakeDevice(Context context) {
        fullWakeLock.acquire();

        //KeyguardManager keyguardManager = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE);
        //KeyguardManager.KeyguardLock keyguardLock = keyguardManager.newKeyguardLock("TAG");
        //keyguardLock.disableKeyguard();

}

public static boolean fullWakeLockActive() {
   return fullWakeLock != null;
}

}

这里正在获取fullWakeLock

if (makeUseOfNewLocation(location) < 20) {
                if (WakeLocker.fullWakeLockActive())
                    WakeLocker.wakeDevice(allert.getMA());
                if (callProgress.isOffHook()) {
                    new BlinkBack(allert.getMA());
                }

唤醒锁本身无法将设备从睡眠状态唤醒或导致设备出现在前台。您必须使用位置服务或警报唤醒设备，然后使用唤醒锁保持设备唤醒并将应用程序的UI组件触发到前台。

你如何使WakeLock流行应用程序前景
