Difference between clean, gradlew clean

./gradlew clean Uses your project's gradle wrapper to execute your project's clean task. Usually, this just means the deletion of the build directory. ./gradlew clean assembleDebug Again, uses your project's gradle wrapper to execute the clean and assembleDebug tasks, respectively. So, it will clean first, then execute assembleDebug, after any non-up-to-date dependent tasks. ./gradlew clean :assembleDebug Is essentially the same as #2. The colon represents the task path. Task paths are essential in gradle multi-project's, not so much in this context. It means run the root project's assembleDebug task. Here, the root project is the only project. Android Studio --> Build --> Clean Is essentially the same as ./gradlew clean. See here.

For more info, I suggest taking the time to read through the Android docs, especially this one.

You can also use

./gradlew clean build (Mac and Linux) -With ./

gradlew clean build (Windows) -Without ./

it removes build folder, as well configure your modules and then build your project.

i use it before release any new app on playstore.

You should use this one too:

./gradlew :app:dependencies (Mac and Linux) -With ./

gradlew :app:dependencies (Windows) -Without ./

The libs you are using internally using any other versions of google play service.If yes then remove or update those libs.
