Build Android Studio app via command line

Question

I want to build an Android Studio app (the Gradle build system), but I want to do this via the command line.

Answer 1

Android Studio automatically creates a Gradle wrapper in the root of your project, which is how it invokes Gradle. The wrapper is basically a script that calls through to the actual Gradle binary and allows you to keep Gradle up to date, which makes using version control easier. To run a Gradle command, you can simply use the gradlew script found in the root of your project (or gradlew.bat on Windows) followed by the name of the task you want to run. For instance, to build a debug version of your Android application, you can run ./gradlew assembleDebug from the root of your repository. In a default project setup, the resulting apk can then be found in app/build/outputs/apk/app-debug.apk. On a *nix machine, you can also just run find . -name '*.apk' to find it, if it's not there.

Answer 2

Try this (OS X only):

brew install homebrew/versions/gradle110
gradle build

You can use gradle tasks to see all tasks available for the current project. No Android Studio is needed here.

Answer 3

there are two build types to build your application using the Gradle build settings: one for debugging your application — debug — and one for building your final package for release — release mode.

Building in Debug Mode

• First Navigate to Android studio project Root folder using CMD

• run this command gradlew.bat assembleDebug

• Output window look like this

Build signed apk in Release Mode

• Edit the build.gradle file to build your project in release mode:

  android {
  ...
  defaultConfig { ... }
  signingConfigs {
      release {
          storeFile file("myreleasekey.keystore")
          storePassword "password"
          keyAlias "MyReleaseKey"
          keyPassword "password"
      }
  }
  buildTypes {
      release {
          ...
          signingConfig signingConfigs.release
      }
  }}
  

• run this command gradlew.bat assembleRelease

Done.Good Luck!
