Why Use IntelliJ IDEA?

Here are the reasons we are going to use IntelliJ instead of the other IDEs.

  1. Android Studio. Since our aim is to end up writing Android apps, Android Studio IDE is based on the IntelliJ platform.
  2. Auto-complete. IntelliJ have a smart-code completion and its extremely fast. The IDE will anticipate what you need to type most of the times.
  3. Code-assistance. If you make a mistake, a red light bulb shows up in the IDE and offers suggestions. A yellow one for improvements and warnings.
  4. Auto-import. IntelliJ have a feature that automatically imports the packages you need. No need to remember in which package the class belongs to.
  5. Refactoring. You can easily re-factor your code.
  6. Gradle. IntelliJ have good support for the Gradle build system. We can add libraries from Maven in a couple of clicks.
