你有更好的方法使设备100％唤醒吗？我反复调用acquire（），但我不确定这是否正确。或者我应该只调用一次acquire（）？或者我应该使用Intent.ACTION_SCREEN_OFF？正确的方法来100％唤醒我的设备？
public class MyServiceThatKeepsTheDeviceAwake extends IntentService {
TAG = "com.android.browser.test.launcher.BrowsePageService";
...
@Override
public void onCreate() {
super.onCreate();
mPowerManager = (PowerManager) getSystemService(Context.POWER_SERVICE);
mWakeLock = mPowerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK |PowerManager.ACQUIRE_CAUSES_WAKEUP |PowerManager.ON_AFTER_RELEASE, TAG);
}
@Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
mWakeLock.acquire();
}
// No release
*该服务使用AlarmManager每20秒
---附加运行：
*这让我的FF。输出时反复运行它。这个应该有什么问题吗？是否有任何问题反复调用？

最好的办法是将其设置睡眠与超时值“从不”的设置。但您需要手动为所有设备执行此操作 – Krish 2012-03-26 05:40:05
摩托罗拉xoom没有“从不”选项，或者并非所有设备都具有该选项。我应该怎么做？ – quiel 2012-03-26 05:45:04
然后，您应该将该值设置为最长时间，如1小时或更长时间 – Krish 2012-03-26 05:46:01
