Appium Android не удалось выполнить команду adb pm pull

Question

Я использую клиент Appium Desktop 1.7.1 с сервером 1.9.1 и eclipse для запуска тестового скрипта на Windows и MacOS.

Я использую Java для написания своего тестового скрипта и проекта с maven,junit 4.12 и appium java-client 6.0.1

Я использую Android Studio 3.2.1 для запуска приложения Android на эмуляторе SDK 28, затем запускаю appium server в клиенте для настольных ПК, затем запускаю мой тестовый скрипт в eclipse.

После того, как в эмуляторе установлено какое-то вспомогательное приложение appium, появляются следующие ошибки.

Похоже, команда pull не выполнена.и вот мои возможности

capabilities = new DesiredCapabilities();
capabilities.setCapability("deviceName","Android");
capabilities.setCapability("platformName","Android");
capabilities.setCapability("appPackage", "com.apps.appium");
capabilities.setCapability("automationName", "UiAutomator2");
capabilities.setCapability("appActivity", ".MainActivity");
capabilities.setCapability("no-reset", "true");

Может кто-нибудь помочь?Может я что то пропустил?

Почему бы вам не использовать прямой метод аппиума pullFile для этого.Ниже приведен пример использования для различных типов файлов

@Test
public void pullTextFileFromMobileSDCardTest() throws IOException {
    byte[] returnData = _driver.pullFile("/storage/sdcard1/mili_log.txt");
    //System.out.println(" Printing Text of File received from mobile :: " + new String(Base64.decodeBase64(returnData)));
    File fs = new File("C:\\eclipse\\MobileFile.txt");
    FileOutputStream fos = new FileOutputStream(fs);
    fos.write(returnData);
    fos.flush();
    fos.close();
}   

  @Test     
  public void pullImageFileFromMobileSDCardTest() throws IOException {
      byte[] returnData = 
    _driver.pullFile("/storage/sdcard1/IMG_20140828_072840.jpg");
   //System.out.println("Base 64 Converted String received from mobile :: " + returnData);
    BufferedImage image=ImageIO.read(new ByteArrayInputStream(returnData));
    ImageIO.write(image, "jpg", new File("C:\\eclipse","snap.jpg"));
 }

 @Test
  public void pullVideoFileFromMobileSDCardTest() throws IOException {
        byte[] returnData = _driver.pullFile("/storage/sdcard1/VideoIconfile.mp4");
       //System.out.println(" Printing Text of File received from mobile :: " + new String(Base64.decodeBase64(returnData)));
        FileOutputStream fos = new FileOutputStream("C:\\eclipse\\video.mp4");
        fos.write(returnData);
        fos.flush();
        fos.close();
  }
