Answer 1

The error does gives some hint about whats wrong happening :

Build info: version: '3.0.1', revision: '1969d75', time: '2016-10-18 09:49:13 -0700'System info: host: 'Latitude-E5540', ip: '127.0.1.1', os.name: 'Linux', os.arch: 'amd64', os.version: '4.10.0-42-generic', java.version: '1.8.0_131'
Driver info: driver.version: AndroidDriver

The error clearly mentions that the AndroidDriver is not getting detected back as in :

Driver info: driver.version: AndroidDriver

Your main issue is the version compatibility between the binaries you are using as follows :

• You are using AndroidDriver but the version and details are unknown to us.
• Your Web Client version and details is unknown to us.
• Your Selenium Client version is 3.0.1 of 2016-10-18 09:49:13 -0700 which is almost 1.5 years older.
• Your JDK version is 1.8.0_131 which is pretty ancient.
• Your TestNG version is 6.8 which is pretty old.

So there is a clear mismatch between the JDK v8u131 , Selenium Client v3.0.1 , AndroidDriver version, TestNG version and the Web Client version.

Solution

• Upgrade JDK to recent levels JDK 8u162.
• Upgrade Selenium to current levels Version 3.11.0.
• Upgrade TestNG to current levels Version 6.14.2.
• Upgrade AndroidDriver to current levels.
• Upgrade Web Client to current levels.
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
• If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
• take a System Reboot.
• Execute your @Test.
