Monkeyrunner 的 takeSnapshot() 错误

发布于 2024-12-11 03:59:57 字数 11362 浏览 0 评论 0原文

我正在测试 Monkeyrunner 并使用下面的 .py 文件进行屏幕截图。

生成屏幕捕获图像，但有时会在“resulet = device.takeSnapshot()”中出现错误，

我不知道问题是什么。 我用Eclipse测试过。 (Eclipse -> AVD , Skin WVGA854)

请帮助我~谢谢~

    # Imports the monkeyrunner modules used by this program
    from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice, MonkeyImage

    # Connects to the current device, returning a MonkeyDevice object
    device = MonkeyRunner.waitForConnection()

    # Installs the Android package. Notice that this method returns a boolean, so you can test
    # to see if the installation worked.
    #device.installPackage('D:\\study_java\\monkeyrunner\\HelloAndroid.apk')

    # sets a variable with the package's internal name
    package = 'com.example.helloandroid'

    # sets a variable with the name of an Activity in the package
    activity = 'com.example.helloandroid.HelloAndroid'

    # sets the name of the component to start
    runComponent = package + '/' + activity

    # Runs the component
    device.startActivity(component=runComponent)

    # Takes a screenshot
    MonkeyRunner.sleep(0.5)
    result = device.takeSnapshot()
    # Writes the screenshot to a file
    result.writeToFile('D:\\study_java\\monkeyrunner\\screen_shot.png','png')

下面是错误日志。

I am testing monkeyrunner and using below .py file for screencapture.

screencapture image is generated but sometimes it occurs error in "resulet = device.takeSnapshot()"

I don't know what's the problem.
I have tested it with Eclipse. (Eclipse -> AVD , Skin WVGA854)

Please help me~ Thanks~

    # Imports the monkeyrunner modules used by this program
    from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice, MonkeyImage

    # Connects to the current device, returning a MonkeyDevice object
    device = MonkeyRunner.waitForConnection()

    #device.installPackage('D:\\study_java\\monkeyrunner\\HelloAndroid.apk')

    # sets a variable with the package's internal name
    package = 'com.example.helloandroid'

    # sets a variable with the name of an Activity in the package
    activity = 'com.example.helloandroid.HelloAndroid'

    # sets the name of the component to start
    runComponent = package + '/' + activity

    # Runs the component
    device.startActivity(component=runComponent)

    # Takes a screenshot
    MonkeyRunner.sleep(0.5)
    result = device.takeSnapshot()
    # Writes the screenshot to a file
    result.writeToFile('D:\\study_java\\monkeyrunner\\screen_shot.png','png')

Below is error log.

你问这个问题已经很久了，但无论如何，这就是答案。当您尝试将屏幕截图保存在指定的文件夹中时，您的代码会出现异常。如果您将以下代码更改

result.writeToFile('D:\\study_java\\monkeyrunner\\screen_shot.png','png')

为：

result.writeToFile('D:/study_java/monkeyrunner/screen_shot.png','png')

那么您应该可以开始了！如果您遇到任何其他问题，请告诉我。

It has been so long since you asked this question but here is the answer anyway. Your code gives exception when you try to save the screen capture in the folder that you specified. If you change the following code:

result.writeToFile('D:\\study_java\\monkeyrunner\\screen_shot.png','png')

into:

result.writeToFile('D:/study_java/monkeyrunner/screen_shot.png','png')

Then you should be good to go! Please let me know if you encounter any other problems.
