blocks|key|163706|text|您可以使用dumpsys+power命令通过adb检查设备的当前电源状态(包括显示器)，并仅在显示器关闭时发送电源键按下事件。更简单的解决方案是在开发者选项中完全禁用“连接到USB时”的显示超时。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|163707|entityMap^0|5|D|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

You can check device's current power state (including display) via adb with <code>dumpsys power</code> command and send the power key press event only if the display is off. The easier solution would be disabling the display timeout altogether "while connected to USB" in the Developer options.

you could also add the following flags to your <code>onCreate()</code> in your main activity:

<pre><code>getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
</code></pre>

This way your device should wake up when it is loaded onto the device through Eclipse.

Here's what I came up with:

<pre><code>adb shell dumpsys power | grep "mScreenOn=true" | xargs -0 test -z &amp;&amp; adb shell input keyevent 26
</code></pre>

This will first check to see if the screen is on. If it isn't, it will emulate the power key, which will turn on the device's screen.

blocks|key|163823|text|对于Windows和Eclipse，您可以使用.bat文件：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|163824|@ECHO+OFF

:end
exit|code-block|syntax|javascript|163825|它将检查，如果屏幕关闭，它将切换到电源状态。要在Eclipse中使用它，这个导入文件应该被用作“外部工具”(只需填充.bat的路径)，并在其属性(生成器-导入-)中链接到项目。|163826|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

For Windows and Eclipse you can use .bat file:

<pre><code>@ECHO OFF
setlocal
for /f "delims= tokens=1*" %%a in ('adb shell dumpsys power ^| findstr.exe "mScreenOn="') DO (
for /f "delims== tokens=2*" %%S in ("%%a") do (
if "%%S" == "false" (goto move1) else (goto move2)
)
)

:move1
adb shell input keyevent 26
goto end

:move2
goto end

:end
exit
</code></pre>

It will check, if screen is off it will switch the power state.
To use it with Eclipse this .bat file should be used as "External tool" (just fill the path to the .bat) and linked to the project in it's properties (Builders - Import - ).

<pre><code>adb shell input keyevent KEYCODE_WAKEUP

As described <a href="http://developer.android.com/reference/android/view/KeyEvent.html#KEYCODE_WAKEUP">here</a>, this wakes up the device. Behaves somewhat like KEYCODE_POWER but it has no effect if the device is already awake. 

To toggle sleep/wake with one command you can issue 

<pre><code>adb shell input keyevent KEYCODE_POWER
</code></pre>

blocks|key|164009|text|我知道这与OP所要求的相反，但是我想为其他读者指出“真正睡眠”的定义:如果adb是活动的，那么设备就不是真正的睡眠，因为USB是打开的并且命令提示符正在运行(否则adb+shell如何工作？)。完全睡眠时，只有物理电源按钮会唤醒它(除非在BSP中选择其他按钮作为唤醒源)。我的项目在屏幕关闭的情况下绘制了大约120+My，但在睡眠模式下只有23+My(断开USB电缆)。"adb+shell+input+keyevent+26“在此模式下不起作用。串行控制台也不需要。我的测试夹具确实可以单独连接电池和外部电源线。我可以切换电源线(连接电池)来唤醒它。我还有一个切换的USB集线器，它专门为测试的休眠部分断开USB。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|164010|我希望这能对某些人有所帮助。|164011|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I know that this is the opposite of what the OP requested, but I wanted to point out the definition of "truly asleep" for other readers:
If adb is active, then the device is not truly asleep, since USB is on and the command prompt is running (how else is adb shell going to work?). When fully asleep, only the physical power button will wake it (unless other buttons are selected as a wake source in the BSP). My project draws about 120ma with screen off, but only 23ma in sleep mode (disconnect USB cable). "adb shell input keyevent 26" does not work in this mode. Neither does the serial console.
My test fixture does have access to the battery and external power line separately. I can toggle the power line (with battery connected) to wake it up. I also have a switched USB hub that disconnects the USB specifically for the sleep portion of the test.

I hope this can be some help to someone.

How to wake up Android with use adb - I want to wake up (if asleep) Android terminal before debugging every new version of application.

Typical flow is:
1. I do some changes in Eclipse.
2. In the meantime screen goes off or not.
3. I run "debug" and want force screen to wake up.

I found a method with "power key" emulation but it does not turn it on but rather toggles the power state. I do not want to add extra code to my application. What are the other methods to do such trivial task, please help.

Wake up Android with use adb or Eclipse (just before debug)?
