你有更好的方法使設備100％喚醒嗎？我反覆調用acquire（），但我不確定這是否正確。或者我應該只調用一次acquire（）？或者我應該使用Intent.ACTION_SCREEN_OFF？正確的方法來100％喚醒我的設備？
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
*該服務使用AlarmManager每20秒
---附加運行：
*這讓我的FF。輸出時反覆運行它。這個應該有什麼問題嗎？是否有任何問題反覆調用？

最好的辦法是將其設置睡眠與超時值「從不」的設置。但您需要手動爲所有設備執行此操作 – Krish 2012-03-26 05:40:05
摩托羅拉xoom沒有「從不」選項，或者並非所有設備都具有該選項。我應該怎麼做？ – quiel 2012-03-26 05:45:04
然後，您應該將該值設置爲最長時間，如1小時或更長時間 – Krish 2012-03-26 05:46:01
