How to build an Android APK file without using Android Studio in a Capacitor project?

Capacitor
#23

Totally Agree.
Capacitor uses the native IDE for each platform in order to provide required configuration, and to build, test, and deploy apps.

I found an article on this. I think it might valuable. But it is for cordova. It is applicable for capacitor too

#25

Thank you so much. It really helpful

Sorry to bring up this thread. I am trying to build using Capacitor for more than 12 hours now. My last attempt was


$ ionic capacitor copy android && cd android && ./gradlew assembleDebug && cd ..

It looked all good until

Welcome to Gradle 5.6.4!

Here are the highlights of this release:

  • Incremental Groovy compilation
  • Groovy compile avoidance
  • Test fixtures for Java projects
  • Manage plugin versions via settings script

For more details see https://docs.gradle.org/5.6.4/release-notes.html

Starting a Gradle Daemon (subsequent builds will be faster)

Configure project :app
google-services.json not found, google-services plugin not applied. Push Notifications won’t work

FAILURE: Build failed with an exception.

  • What went wrong:
    Could not determine the dependencies of task ‘:app:compileDebugJavaWithJavac’.

SDK location not found. Define location with an ANDROID_SDK_ROOT environment variable or by setting the sdk.dir path in your project’s local properties file at ‘/home/meen/PSD/android/local.properties’.

  • Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

  • Get more help at https://help.gradle.org

BUILD FAILED in 2m 35s

I do not know what do. I have tried a lot of things but nothing worked. I am not sure how to make Android Studio work with Ionic/Capacitor. After add android , I tried opening the folder in Android Studio. It says detected framework, gradle etc. But won’t Run or Build. If possible, please help me out.

I am using Ubuntu 20.04.

@Aniee

I also face the same issue, have you find a solution?

#28

No sir. I tried a few things but didn’t work

#29

@pro1 @Aniee, Have you built any other project with android studio, specifically Native android Projects ? did it work? or is this a fresh installation? It seems like you need to define the ANDROID_SDK_ROOT path.

#30

What is mean by cd . . ? Do I have to enter something there…??

#31

cd .. is the command to change directories to the parent of the current directory. The “…” indicates the parent directory.

#32

Registered an account with Ionic forums just to say thank you to @codebru and @kazlauskis ! I ought both of you a beer.

@Aniee try this: open (create if not exists) android/local.properties, and add:

sdk.dir=/path/to/your/android_sdk

For example mine says: sdk.dir=/home/matias/Downloads/android

The directory should have subdirectories like build-tools/, tools/, emulator/, platform-tools/, etc… i.e. the directory where you installed or unzipped the android sdk. Hope this helps.
