Something to get started running python from inside an Android app

Running Python inside an Android app can be achieved through several methods, each with its unique implementation approach. The choice of method depends on your specific requirements, such as the level of Python integration needed, performance considerations, and the complexity of the Python code you intend to run. Here are a few approaches:

1. Using Pydroid 3 or Similar Apps

Pydroid 3 is a Python 3 IDE for Android that can be used to run Python scripts on Android devices. While this is more of an educational or development tool rather than a method for integrating Python into an Android app, it can be useful for testing Python code on Android.

2. Using Chaquopy:

Chaquopy is a plugin for Android Studio that enables you to include Python code as part of your Android app. Here's how you can use it:

1. Setting up Chaquopy in Android Studio:

   • Add Chaquopy to your project by adding its Maven repository and plugin to your build.gradle files.
   • Enable Python support by adding the appropriate plugin and dependencies configurations.

2. Adding Python Files:

   • Place your Python files in the src/main/python directory of your project.

3. Accessing Python Code from Java/Kotlin:

   • Use the Python API provided by Chaquopy to call Python functions from Java or Kotlin. This involves initializing the Python instance and calling your Python functions.

3. Using Kivy or BeeWare:

• Kivy is a Python framework for developing multitouch applications. It's cross-platform (Linux/OS X/Windows/Android/iOS) and released under the MIT license. You can develop your app in Python and then deploy it to Android.
• BeeWare is a collection of libraries and tools for building native user interfaces. With BeeWare, you can write your app in Python and then compile it to a standalone Android package.

4. SL4A (Scripting Layer for Android):

SL4A (no longer actively developed but still available) allowed for running various scripting languages, including Python, on Android. It provided a simplified Android API for calling Android functions from scripts. However, its capabilities are limited compared to native app development.

5. Using Termux:

Termux is a terminal emulator for Android, which allows you to run a Linux environment directly on your Android device. You can install Python through Termux and run Python scripts. However, this is not the same as integrating Python into an Android app; it's more about running scripts independently.

Example: Chaquopy Setup

Here is an example of how you might set up Chaquopy in your build.gradle (Module):

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext {
        chaquopyVersion = '9.1.0'  // Change to the latest version
    }
    repositories {
        google()
        mavenCentral()
        maven { url "https://chaquo.com/maven" }
    }
    dependencies {
        classpath "com.android.tools.build:gradle:7.0.2" // Use the correct Gradle version
        classpath "com.chaquo.python:gradle:$chaquopyVersion"
        // NOTE: Ensure you use the correct version of Chaquopy and other tools.
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url "https://chaquo.com/maven" }
    }
}

And in your build.gradle (App):

apply plugin: 'com.android.application'
apply plugin: 'com.chaquo.python'

android {
    // configuration settings like compileSdkVersion, etc.
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "com.chaquo.python:android:9.1.0" // Use the correct Chaquopy version
}

python {
    // Python version and other settings
    buildPython "3.8.10" // Use the correct Python version
}

This setup is just the beginning. You would need to follow the documentation specific to the tool you choose to integrate Python into your Android application fully. Remember that while integrating Python into Android provides powerful capabilities, it can add complexity and increase the size of your application. Consider whether the benefits outweigh these factors for your specific use case.

Mildly related but are there any android-phone-as-server out there that aren't just an fdroid experiment? 'cause that could serve as a base for this.
