Rock your Android

This is an extension for Android Lint, adding new rules:

• RootPackage : Every .java file must be inside a custom package, not inside the root package. ERROR
• MissingLauncher : Every application must have at least one launcher activity. WARNING
• MoreThanOneLauncher : The application must have only one launcher activity. WARNING
• LauncherActivityInLibrary : A library must not have a launcher activity. ERROR
• IconInLibrary : A library must not have icons. ERROR
• PermissionUsageInLibrary : A library must not use permissions. ERROR
• InstanceVariableName : Every instance variable must be named beginning with 'm' and using camelCase. WARNING
• ClassConstantName : Every class constant (static and final) must be named using UPPER_SNAKE_CASE. WARNING
• HardcodedText : A string cannot be hardcoded inside layouts or menus. Now this is an error, not a warning. ERROR
• LayoutIDFormat : Every id inside layouts or menus must be named using lowerCamelCase. ERROR

Exceptions to InstanceVariableName rule:

1. The class is a model (should be inside a package called 'models').
2. The variable is declared using @Bind or @InjectView (ButterKnife).

Clone this repository

git clone https://github.com/inaka/lewis.git

Enter to the project

cd lewis/

Build it

./gradlew build

Install it

./gradlew install

Verify whether the issues are registered with lint

lint --show RootPackage

Go to any Android project and run lint

./gradlew lint

Note: If you can't run lint directly, you may want to include android tools PATH in your ~/.bash_profile. (i.e. PATH=$PATH:~/Library/Android/sdk/tools)

Then run source ~/.bash_profile.

Add on your build.gradle file

android {
    lintOptions {
        disable 'RootPackage','MoreThanOneLauncher'
        ...
    }
}
