#screen on

Android Power State Change

I forgot if I did this before or if it worked before. I add these two intent filters to AndroidManifest.xml

Intent.ACTION_SCREEN_ON Intent.ACTION_SCREEN_OFF

but it wouldn’t work. That’s super weird. Cause that’s a very basic and simple setting. After searching a little while, I realize that’s PowerManager setting. Check the Notifier.java here.

Just open the flip cover to turn on screen. And close the flip cover to turn off screen. Screen on when the cover or something gets away from the proximity sensor. Screen off when the cover or something approaches the proximity sensor. This app do not need rooting or device administration (system app). So it is easy to install.

一般來說有些app在安裝時，都會出現一個「防止手機進入待命狀態」

但是有時只是希望app在同步或是一些流程時，不想讓手機進入休眠

這時可以加入layout flag來讓app暫時不要進入待命狀態。

主要是加入此flag：FLAG_KEEP_SCREEN_ON

使用方式為在你需要暫時停止手機進入待命狀態的流程當中加入

// 此時暫時不讓手機進入待命狀態 getWindow().addFlags(android.view.WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

當流程執行完畢後，希望可以讓app回到自動進入待命狀態的話，此時在流程結束的地方加入

// 此時讓手機回復進入自動待命狀態 getWindow().clearFlags(android.view.WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
