Trick to sign app everywhere

A simple tutorial to sign your app on remote build machine

1. Get your keystore file. For example, key.jks
2. Convert keystore to .txt file via openssl and base64 tools:

   openssl base64 < `key.jks` | tr -d '\n' | tee keystore.txt

   Linux has this tools preinstalled

3. Content of keystore.txt use as you want:
   1. Copy to github secrets
   2. Copy to Azure DevOps pipeline variables
   3. Copy somewhere else in a secure place
4. Parse keystore.txt back

   echo keystore.txt | base64 --decode > keystore.jks

5. Use keystore.jks as it was in step 1

Build android apk with docker

1. Set environment variables
   1. Mode keystore.jks file in root folder
   2. Create .env file:

      SIGNING_KEY_ALIAS=set-key-alias-here
      SIGNING_KEY_PASSWORD=set-key-password-here
      SIGNING_STORE_PASSWORD=set-keystore-password-here

2. Build and run image

   This command uses compose.yaml file with deploy/Dockerfile-release

   docker compose up --build

3. Check output-release folder for *.apk files
4. To use debug build task or dev api, you can override CMD command in Dockerfile via docker compose. Example:

   services:
     android-builder:
       build:
         dockerfile: deploy/Dockerfile-release
         context: .
       command: ./gradlew :app:assemble[Prod|Dev]Api[Release|Debug]
