gradle and java increase RAM with each build

[Neizvestnyj]

Versions

• Python: 3.9.7
• OS: Linux (Debian 13)
• Buildozer: 1.4.0.dev0
• Kivy: 2.1.0
• Cython: 0.29.30
• OpenJDK: 11.0.15
• VM RAM: 7Gb

The same is true when using ndk 19c, but less memory is consumed with each build.

buildozer.spec

android.api = 33 # 32
android.ndk = 23b
android.extra_manifest_application_arguments = ./android/extra_manifest_application_arguments.xml
android.gradle_dependencies = <dependencies>
android.enable_androidx = True
android.add_gradle_repositories = "mavenCentral()"
android.archs = arm64-v8a, armeabi-v7a
android.numeric_version = 7115
p4a.branch = develop
p4a.source_dir = ../python-for-android # from develop branch
p4a.bootstrap = sdl2

logs after 5 big app build:

After first main app build

Each subsequent assembly takes up RAM: + 100Mb in RAM

Build test app + main app

buildozer android clean and deleting .gradle in home folder - does not help

When I use old p4a version (with ndk 19c) and build app twice.

pkill -9 -e -f java - solve issue

I have same issue

[kuzeyron]

Is this still a problem?

[sivefunc]

I think it's a problem related to Gradle in Linux and not P4A, I'm currently learning Flutter and found the same problem when building to Android in the sense that memory is not freed when building is finished and increases in each build.
