It been while since I began studying android development. I am able to make small apps. I have two questions
1. How are libraries used to build project. what is gradle and java build path. I tried to google it but only got confused. Can anyone explain me with workflow.
2. In some projects I get error that minimum api required is greater than what i use. So how can I make it compatible for lower api's too.
And sorry for my language.

  • Take a look at this course for absolute Android beginners for non-programmers from Google itself (in partnership with Udacity) https://www.udacity.com/course/android-development-for-beginners--ud837 (avoid clicking on the 14-day trial and avoid clicking on anything that mentions a nano-degree, click on the blue button to access the materials for free, email registration will still be required, but at least, it won't ask you for your credit card information). This particular beginner course is too basic for most people, but it should be a good introduction for you. – Stephan Branczyk Oct 02 '15 at 19:26

  1. What is gradle?

Gradle is one type of build tool that build the source code of the program. So it's an important part of Android Studio, and needs to be installed before starting developing your application. We do not have to install it separately, because the Android Studio does it for us, when we make our first project in the Android Studio.

The java build path is used for building your application. It contains all of your source files and all Java libraries that are required to compile the application.

  1. In some projects I get error that minimum api required is greater than what i use.

As stated by maxim in their answer here:

Methods from higher API are invisible and inaccessible because project's target SDK is lower than SDK which methods are going to be used. For example: if you want to use methods from API 14 Android project target SDK should be at least 14 or even better the latest (currently 16). That is kind of obvious but I missed it. After that the solution Sam gave a reference to is in use.

Calling API from higher API level than the minimum requirement
