java - 无法通过appium在android模拟器中启动计算器

Question

我只是创建了一个示例代码，如下所示，用于启动计算器 apk 文件并执行一些任务

@BeforeSuite
    public static void driverInitalize() throws Exception {
        try {

            DesiredCapabilities capabilities = new DesiredCapabilities();
            capabilities.setCapability("deviceName", "Android Emulator");
            capabilities.setCapability("platformName", "Android");
            capabilities.setCapability("platformVersion", "4.2.2");
            // capabilities.setCapability("browserName", "Chrome");
            capabilities.setCapability("appPackage", "com.android.calculator2");
            capabilities.setCapability("appActivity", "com.android.calculator2.Calculator");
            capabilities
                    .setCapability("app",
                            "C:\\Ecare\\Appium\\com.android.calculator2-5.1-1720659-22-minAPI22.apk");
            driver = new RemoteWebDriver(
                    new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

    @Test
    public static void sampleTest1() throws Exception {
        try {

            // System.out.println(driver.getTitle());
            driver.findElement(By.xpath(".//*[contains(text(),'7')]")).click();
            driver.findElement(By.xpath(".//*[contains(text(),'+')]")).click();
            driver.findElement(By.xpath(".//*[contains(text(),'3')]")).click();
            driver.findElement(By.xpath(".//*[contains(text(),'=')]")).click();
            String value = driver.findElement(
                    By.className("android.widget.EditText")).getText();
            System.out.print(value);
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

    @AfterSuite
    public static void tearDown() throws Exception {
        try {

            driver.quit();

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

每当我执行上述代码时，appium 服务器以及 eclipse IDE 中都会返回以下异常。有人可以告诉我如何克服这个问题。 session 似乎正在进行，但我不确定如何终止较早开始的进度 session 。我尝试以 appium --no-reset 方式启动 appium 服务器，并检查覆盖现有 session ，但没有成功。

请帮帮我。

Answer 1

您收到的错误[INSTALL_FAILED_OLDER_SDK]是由于您的avd/设备的android版本比用于编译应用程序代码的版本旧而引起的。检查目标sdk版本和应用程序的最低sdk版本。

如果您有权访问应用程序的源代码，这些信息将位于 android:minSdkVersion 标记的 list 文件中。
