org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session

Issues/Bugs
1

Appium is started successfully, but the issue is on launching mentioned specified apk file. Please help me to solve this issue.

Steps Followed:

  1. Started appium in my java program.

  2. Launched AVD Emulator automatically
    ex: emulator-5554

  3. Initialized launched emulator node port using Selenium Grid concept
    ex:
    appium -a 127.0.0.1 -p 50785 -bp 2254 --udid emulator-5554 –session-override

  4. Then launching specified mentioned apk into emulator produced unreachable browser exception.

Output:
