Android build requirements

[ZiadJ]

I'm not sure which software versions are required for building Android. Here's my environment setup:

• Node.js v18.x
• JDK 17
• Gradle 8.5
• Android SDK (API 35, Build Tools 35.0.0)
• Cordova CLI (npm install -g cordova)

It's building successfully for web but for Android I get this:

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.13/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

STDOUT
FAILURE: Build failed with an exception.

• What went wrong:
  Could not determine the dependencies of task ':app:packageDebug'.

Could not create task ':app:compileDebugJavaWithJavac'.
In order to compile Java 9+ source, please set compileSdkVersion to 30 or above

• 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.

@GonzaloGM Did you install Android Studio to be able to build for Android, or did you install specific SDK/library versions separately? Any guidance would be appreciated.

[GonzaloGM]

@ZiadJ I have Android Studio installed, yes, I think I had to install some SDK versions, but it's been a long time so can't remember. This is the command I run to run it in the device:

build-capacitor-android-local: npm run build:android && cp -r dist/default/production/www/* www/ && npx cap run android --target d59fb3c7

d59fb3c7 is the device ID from adb for my phone. I think we need to run some npx commands before it (npx cap sync?). Sorry for the crappy information, let me know if you're able to run it if not I can ask other member who's more used to app development.

[ZiadJ]

@GonzaloGM Can I know which version of Android Studio you have? Also, may be you can run this command and share the output just to give me an idea on what environment you're on:

node -v && gradle -v && cordova -v

[GonzaloGM]

@ZiadJ node -v
v22.16.0

Android Studio:
Build #AI-242.23726.103.2422.12816248, built on December 17, 2024

Gradle 8.2.1

Build time: 2023-07-10 12:12:35 UTC
Revision: a38ec64d3c4612da9083cc506a1ccb212afeecaa

Kotlin: 1.8.20
Groovy: 3.0.17
Ant: Apache Ant(TM) version 1.10.13 compiled on January 4 2023
JVM: 11.0.26 (Homebrew 11.0.26+0)

I don't think we use Cordova anymore.

cordova -v
zsh: command not found: cordova

@GonzaloGM Well, I installed the latest version of Android Studio but that didn't help apparently. gradle -v says I have Gradle 8.2.1 just like you, and JVM 11.0.0.2 but the build is complaining about Gradle requiring Java 17:

Failed to apply plugin 'com.android.internal.application'.
Android Gradle plugin requires Java 17 to run. You are currently using Java 11.
Your current JDK is located in D:\Java\jdk-11
You can try some of the following options:
- changing the IDE settings.
- changing the JAVA_HOME environment variable.
- changing org.gradle.java.home in gradle.properties.

I have no idea how to proceed at this point since I tried with JDK 17 before and that gave me the errors mentioned initially.

Hi, I reviewed 'Android build requirements' and can start immediately. I can deliver a first usable version quickly and iterate based on your feedback. If this scope still matches your priority, I can proceed right away.

[GonzaloGM]

@ZiadJ I remember having to install the latest version JDK 23 I think. If I run:

/usr/libexec/java_home -v
java_home: option requires an argument -- v
/opt/homebrew/Cellar/openjdk/23.0.2/libexec/openjdk.jdk/Contents/Home

Maybe try that?

[ZiadJ]

@GonzaloGM Here's what JDK 23 has to say:

Could not determine the dependencies of task ':app:packageDebug'.

Could not create task ':app:compileDebugJavaWithJavac'.
In order to compile Java 9+ source, please set compileSdkVersion to 30 or above

@michaellinhq I'm not quite sure I understand what you're trying to get to but feel free to elaborate.

[ZiadJ]

/usr/libexec/java_home -v
java_home: option requires an argument -- v
/opt/homebrew/Cellar/openjdk/23.0.2/libexec/openjdk.jdk/Contents/Home

@GonzaloGM All I did actually was upgrade to JDK 23 and I'm not sure where to apply the above settings you shared.

[GonzaloGM]

@ZiadJ So you tried upgrading to JDK and that didn't work either? Which commands did you try for building and what output are you getting currently? Try tagging Pablo Botta when you reply, maybe he has an idea.
