BUILD FAILED: Deprecated Gradle features were used in this build

I am experiencing an issue while trying to launch Zingo Mobile after a successful build on my Arch Linux system. The build process completes successfully, but I am unsure of the next steps required to launch the application. Below are the details of my environment and the steps I have taken.

Environment:

Operating System: Arch Linux uname -a: Linux sebashack 6.10.7-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 29 Aug 2024 16:48:57 +0000 x86_64 GNU/Linux

Android SDK: ANDROID_HOME: ${HOME}/Android/Sdk|

bashrc and bash_profile configurations are set as follows:

bash

export ANDROID_HOME="${HOME}/Android/Sdk"
export PATH="${PATH}:${ANDROID_HOME}"
export PATH="${PATH}:${ANDROID_HOME}/build-tools"
export PATH="${PATH}:${ANDROID_HOME}/platform-tools"
export PATH="${PATH}:${ANDROID_HOME}/cmdline-tools/latest/bin"
export PATH="${PATH}:${ANDROID_HOME}/emulator"

Environment:

OS: Arch Linux 6.10.7-arch1-1
Gradle Version: 8.2
Rust Version: rustc 1.83.0-nightly (bd53aa3bf 2024-09-02)
Android SDK Version: Api 30
Docker Version: Docker version 27.2.0, build 3ab4256958

Current Behavior:

The build completes successfully, but I am unable to launch the zingo-mobile application. The application does not appear to start, and there are no clear error messages indicating the issue. Expected Behavior:

The application should launch successfully after a successful build and installation. Additional Information:

I have installed and configured Docker and Android SDK tools according to the project's requirements. I have tried various commands to start the application, including ./gradlew commands and yarn start.

My error when i did yarn start:

You can try with this in a Terminal:

• adb devices (usually you get this name for the emulator: emulator-5554)
• adb -s emulator-5554 reverse tcp:8081 tcp:8081
• yarn start

The problem was the flatpack android instalation, also the docs are outdated, to fix it , i install the android studio and set up it from the tar file, I'm working in a Dockerfile with a plug and play solution for Arch.
