How to create a release signed apk file using Gradle?

Question

I would like to have my Gradle build to create a release signed apk file using Gradle.

I'm not sure if the code is correct or if I'm missing a parameter when doing gradle build?

This is some of the code in my gradle file:

android {     ...     signingConfigs {           release {               storeFile file("release.keystore")               storePassword "******"               keyAlias "******"               keyPassword "******"          }      } } 

The gradle build finishes SUCCESSFUL, and in my build/apk folder I only see the ...-release-unsigned.apk and ...-debug-unaligned.apk files.

Any suggestions on how to solve this?

Answer 1

Easier way than previous answers:

Put this into ~/.gradle/gradle.properties

RELEASE_STORE_FILE={path to your keystore} RELEASE_STORE_PASSWORD=***** RELEASE_KEY_ALIAS=***** RELEASE_KEY_PASSWORD=***** 

Modify your app/build.gradle, and add this inside the android { code block:

...     signingConfigs {     release {        storeFile file(RELEASE_STORE_FILE)        storePassword RELEASE_STORE_PASSWORD        keyAlias RELEASE_KEY_ALIAS        keyPassword RELEASE_KEY_PASSWORD         // Optional, specify signing versions used        v1SigningEnabled true        v2SigningEnabled true    } }  buildTypes {         release {             signingConfig signingConfigs.release         } } .... 

Then you can run gradle assembleRelease

I managed to solve it adding this code, and building with gradle build:

android {     ...     signingConfigs {         release {             storeFile file("release.keystore")             storePassword "******"             keyAlias "******"             keyPassword "******"         }     }     buildTypes {         release {             signingConfig signingConfigs.release         }     } } 

This generates a signed release apk file.
