title: Using Gradle in Android Development
body: <p>Im new to android development and ive seen some old tutorials before regarding its development on Eclipse. i recently download the new Android Studio to use for the development. However, i found something new called gradle files that are present in the projects folder along with the normal files that used to be in the project.</p>
  
  <p>Everytime i try to run the app i get the following error:</p>
  
  <p>"
  Gradle: 
  FAILURE: Could not determine which tasks to execute.
  * What went wrong:
  Task 'assemble' not found in root project 'SampleProject'.
  * Try:
  Run gradle tasks to get a list of available tasks.
  "</p>
  
  <p>Could anyone please explain whats the use of gradle? and do i have to use it while developing android apps?</p>
  
  <p>Thank you</p>
