判断AVD是否已经开启：
adb -s emulator-57409 shell getprop dev.bootcomplete
如果结果返回1代表AVD成功启动了
命令行打开方式：
1、首先你要打开android模拟器 （下面命令行打开的4步骤我是引用百度上的）
1）.找到SDK的tools文件夹，我的在D:\android-sdk-windows\tools；
2）.如果没有创建AVD的话，可以用命令android list targets查看各版本对应的id；
然后android create avd --target 5 --name Android2.2;//我这里5对应的是android2.2
3）.用命令android list avd查看自己以创建的AVD
4）.emulator -debug avd_config -avd Android2.2就可以打开AVD了，就是有点慢
或者在eclipse上直接打开一个android程序。
2、然后输入 adb install xxx.apk，在模拟器上点击对应应用即可（安装apk后的应用程序名不知道的话得仔细找哦，肯定在模拟器上的）。
注：xxx.apk包含路径名，在命令行你只要直接把apk文件拖至windows命令窗口就可以加载完整路径了。

1. The command line to launch the test AVD we just created would be:
$ emulator -avd test -no-window -no-audio -no-boot-anim -port 5580 &
2. The port must be an integer between 5554 and 5584:
$ adb devices
List of devices attached
emulator-5580
device
This shows the device in the device list.
3. The next step is to install the application and the tests:
$ adb -s emulator-5580 install\
TemperatureConverter/bin/TemperatureConverter.apk
347 KB/s (16632 bytes in 0.046s)
pkg: /data/local/tmp/TemperatureConverter.apk
Success
$ adb -s emulator-5580 install\
TemperatureConverterTest/bin/TemperatureConverterTest.apk
222 KB/s (16632 bytes in 0.072s)
pkg: /data/local/tmp/TemperatureConverterTest.apk
Success
4. Then we can use the specified serial number to run the tests on it:
$ adb -s emulator-5580 shell am instrument -w\
com.example.aatg.tc.test/android.test.InstrumentationTestRunner
com.example.aatg.tc.test.EditNumberTests:......
com.example.aatg.tc.test.
TemperatureConverterActivityTests:..........
com.example.aatg.tc.test.TemperatureConverterTests:....
Test results for InstrumentationTestRunner=....................
Time: 25.295
OK (20 tests)
To unlock the screen you can use:
$ adb -s emulator-5580 emu event send EV_KEY:KEY_MENU:1 EV_KEY:KEY_MENU:0
解锁屏幕
向设备发送屏幕解锁命令：
adb shell input keyevent 82
To do this, the following permission should be added to the manifest file
(AndroidManifest.xml), and then disable the screen lock in your application
under test.
To add the permission, add this element to the manifest:
<manifest>
...
<uses-permission android:name="android.permission.DISABLE_KEYGUARD"/>
...
</manifest>
Then in the Activity under test you should add the following code, preferably in
onResume():
mKeyGuardManager =
(KeyguardManager) getSystemService(KEYGUARD_SERVICE);
mLock = mKeyGuardManager.newKeyguardLock("com.example.aatg.tc");
mLock.disableKeyguard();
That is, get the KeyguardManager, then obtain the KeyguardLock specifying a tag,
customize the package name to be able to debug who is disabling the keyguard.
Then disable the keyguard from showing using disableKeyguard(). If the
keyguard is currently showing, it is hidden. The keyguard will be prevented from
showing again until reenableKeyguard() is called.
$ adb -s emulator-5580 shell 'stop; sleep 5; start'
This command line opens the emulator shell for our emulator and runs the stop and
start commands.
The evolution of these commands can be monitored using the logcat command:
$ adb -s emulator-5580 logcat
$ adb -s emulator-5580 emu kill
This will stop the emulator and free the used resources and terminate the emulator
process on the host computer.
