  compile "com.android.support:support-fragment:25.3.1"
  compile "com.backendless:backendless:4.0.+"

Hi Mohammad,

Not sure why it is not resolving. Here’s a link to the latest version in maven:


yes i checked it, i do my job via adding jar files to my project

when you add a dependency into build.gradle, you will be pulling it from maven. If you want to add a jar file, download it from github, link is here: https://backendless.com/documentation/sdks/
