Question

我知道有些人会说这个问题是重复的，但我认为不是。

我在模拟器上安装了App，我正在运行以下代码来检查应用程序是否可用。如果App可用，则返回true，参见下面的代码和结果：

public class Install {

    public AndroidDriver driver;

    @BeforeClass
    @Parameters({"appPackage", "appActivity"})
    public void SetupAndroidDrivers(String _appPackage, String _appActivity) throws MalformedURLException, InterruptedException {

        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("deviceName", "DeviceName");
        capabilities.setCapability("platformName", "Android");
        capabilities.setCapability("appPackage", _appPackage);
        capabilities.setCapability("appActivity", _appActivity); // This is Launcher activity of your app (you can get it from apk info app)

        try {
            driver = new AndroidDriver(new URL("http://0.0.0.0:4723/wd/hub"), capabilities);
            Thread.sleep(30000);
        } catch (IOException e){

        }

    }


    @Test(priority=1)
    @Parameters({"appPackage","Build"})
    public void Test(String _appPackage, String Build) {

        System.out.println("Check if the App is Installed");
        //String appId="com.google.android.youtube";
        System.out.println(driver.isAppInstalled(_appPackage));
    }
}


Check if the App is Installed
true

问题是当应用程序不可用时，它会崩溃，下面是日志文件的详细信息：

注意：我已尝试使用此链接Detect an application is installed or not?中的解决方案，但我无法导入packagemanager或者我错过了什么？

Answer 1

我对java不熟悉，但您可以通过adb命令检查是否安装了应用

adb shell pm list packages [your.package.name]

如果已经安装了app，则上面的命令将返回

package:[your.package.name]

否则它不会返回任何内容，即空字符串。

您可以根据返回使用 if else 并执行所需的操作

Answer 2

您可以使用

driver.isAppInstalled（＆＃34; com.example.AppName＆＃34）;

参考：https://appium.io/docs/en/commands/device/app/is-app-installed/

Answer 3

通过使用

检查包名称来检查是否安装了应用程序

return mContext.getPackageManager().isPackageAvailable(_appPackage);

如果在设备上安装了App，则以编程方式检查
