powermanager

this is my code for setting alarm: public void SetAlarm(Context context, int tag, long time){ AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); Intent i = new Intent(context, Alarm.class); i.putExtra("position", tag); PendingIntent pi = PendingIntent.getBroadcast(context, tag, i, PendingIntent.FLAG_CANCEL_CURRENT); am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+ time, pi); // Millisec * Second * Minute } this is my onRecieve methode: public void onReceive(final Context context, Intent intent){ PowerManager pm = (PowerManager) context.getSystemService

不知不觉中，就收集了超过70条的自己感觉有意思的代码片段，分为三篇文章： android有用代码片段 、 Android有用代码片段（二） 、 Android有用代码片段（三）、 Android有用代码片段（四） 这三篇，今天，开始第五篇的整理！这里解释一下，因为一、二、三都是每个有20个片段，但是在四中，由于第70个代码过长，所以在第四篇中，只有10个片段。 七十一、android自动跳转 有些时候需要类似这样的功能，在一个页面停留2秒后，跳转到另外一个页面！ 第一种方法： [java] view plain copy print ? Timer timer = new Timer(); TimerTask timerTask = new TimerTask() { @Override public void run() { // 你要干的活 } }; timer.schedule(timerTask, 1000 * 2 ); //2秒后执行 Timer timer = new Timer(); TimerTask timerTask = new TimerTask() { @Override public void run() { // 你要干的活 } }; timer.schedule(timerTask, 1000 * 2); //2秒后执行 在run(

I am currently utilizing the below referenced code for a wake lock on an alarm notification activity. However, SCREEN_DIM_LOCK has been depreciated. So, what should I be replacing it with? //Instance of wake lock for AlarmActivity PowerManager pm = (PowerManager) this.getSystemService(Context.POWER_SERVICE); wakeLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "MyWakeLock"); Android Developer documentation specifies that SCREEN_DIM_WAKE_LOCK should be replaced with FLAG_KEEP_SCREEN_ON . After doing a bit of digging, I turned up this... getWindow().addFlags(WindowManager.LayoutParams

I am making an Android app that needs to have the phone reboot or turn off when a button is clicked. Is this possible? Or will the phone require root access? Zelimir You can do that using android.os.PowerManager . Function reboot(String reason) is available, you need permission: android.permission.REBOOT Official site: http://developer.android.com/reference/android/os/PowerManager.html#reboot(java.lang.String) Of course, you are likely to get that permission only if your application is signed with the system signing key: How to compile Android Application with system permissions I did this in
