Build project without Android Studio

Question

How to build Android Studio project using gradle without installing IDE, if i never installed gradle, but i have android sdk and jdk?

Answer 1

If the project was created with Android Studio, it should already have a gradlew script in the root directory, which you can use to execute Gradle from the command line (e.g. gradlew build).

Answer 2

Steps to Build using Command line:

Open CMD and navigate it to project's root directory(You can also navigate to directory first using file Explore and then right click there keeping SHIFT key pressed and select Open Command window Here from available option)

For Debug Builds Run the command :

     gradlew assembleDebug

For Release Builds :

First you need to write the signing configuration inside your module's build.gradle file like

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion '19.0.1'

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 14
    }

    signingConfigs {

         mySigning{
            storeFile file("YOUR_KEYSTORE_PATH")
            storePassword "KEY_STORE_PASSWORD"
            keyAlias "KEY_ALIAS"
            keyPassword "ALIAS_PASSWORD"
         }
     }

     buildTypes {

          release {
             runProguard false
             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
             signingConfig signingConfigs.mySigning
             zipAlign true
          }
      }
  }

After Configuration Run the command

     gradlew assembleRelease

While executing the command it will automatically download required gradle version in you machine . If you want to change the gradle version you have to configure it in build.gradle file inside wrapper task if you have created

task wrapper(type: Wrapper) {
    gradleVersion = '1.4'  //1.4 is version
}

And if applicable you have to change distributionUrl in gradle-wrapper.properties file located at $ROOT_PROJECT_DIR/gradle like

   distributionUrl=http\://services.gradle.org/distributions/gradle-1.9-bin.zip
