Java/Android Code Styles and lint

IntelliJ IDEA code style settings for Java and Android studio projects.

The code styles below are strict rules, not guidelines or recommendations. Contributions to Android that do not adhere to these rules are generally not accepted. We recognize that not all existing code follows these rules, but we expect all new code to be compliant.

In addition to testing that your Android application meets its functional requirements, it's important to ensure that your code has no structural problems. Poorly structured code can impact the reliability and efficiency of your Android apps and make your code harder to maintain.

Install jar and configure:

Import settings.jar into Android Studio. It defines our coding standard.
you just need to use File -> Import Settings option in Android Studio.

Or Install using script

• On Unix, run the install.sh script. Windows users should use install.bat instead.
• Restart IntelliJ if it's running.
• Open IntelliJ Project Settings -> Code Styles, change the code style for the project to the one you want.

How to use lint

In Android Studio, the configured Lint and IDE inspections run automatically whenever you build your app.

With Android Studio, you can also run Lint inspections for a specific build variant, or for all build variants from the build.gradle file. Add the lintOptions property to the android settings in the build file. This code snippet from a Gradle build file shows how to set the quiet option to true and the abortOnError option to false.

android {
    lintOptions {
       // set to true to turn off analysis progress reporting by lint
       quiet true
       // if true, stop the gradle build if errors are found
       abortOnError false
       // if true, only report errors
       ignoreWarnings true
       }
       ...
    }

To manually run inspections in Android Studio, from the application or right-click menu, choose Analyze > Inspect Code. The Specify Inspections* Scope dialog appears so you can specify the desired inspection scope and profile.
