如何防止calabash-android "App没有启动“错误？

Question

我在linux pc上工作，

确保AndroidManifest.xml有访问互联网的权限。使用和不使用代理的尝试命令，观察结果是相同的。

我的真实设备安装了4.1.1版的android软件，

AVD的android版本是4.2.2，API级别是17，这会有问题吗？

我观察到，示例演示应用程序在设备上启动，而我运行'calabash-android run AndroidDemoProject.apk...‘，但命令抛出错误，显示“应用程序未启动”(RunTimeError)。

错误详细信息：

请让我知道，如果有任何解决这个问题的办法…

Answer 1

当我遇到这个错误时，我可以通过这样做来解决这个问题：

1)关闭AVD并重启

2)如果(1)不能解决问题，请卸载应用程序，然后再次对应用程序执行reinstall_apps

3)如果(2)不能解决问题，请删除测试服务器文件夹并再次执行start_test_server_in_background。

Answer 2

添加以下代码也可以解决这个问题。

<uses-permission android:name="android.permission.INTERNET" />

Answer 3

您也可以尝试这种方式。在你的ruby文件夹中找到文件operations.rb。路径类似于此"C:\Ruby23-x64\lib\ruby\gems\2.3.0\gems\calabash-android-0.7.3\lib\calabash-android".打开文件并找到代码块：

    Retriable.retriable :tries => 100, :interval => 0.1 do
              raise "App did not start" unless app_running?

将"tries“参数值改为300，而不是100。它将帮助您的应用程序在生产效率不高的设备上运行。我们已经用默认设置测试了6种不同的设备，但只有2款旗舰智能手机(三星galaxy S6)可以运行"tries“参数值为=> 100的应用。现在我们所有的设备都可以很好地运行应用程序了！
