Quick Start

Python API

from androbuilder import Builder

# Simple build
builder = Builder(path="./MyApp", sdk="34")
apk_path = builder.build("./output")
print(f"APK built: {apk_path}")

# Advanced build
builder = Builder(
    path="./MyApp",
    sdk="34",                    # Auto-downloads SDK 34
    ndk="25.1.8937393",         # Auto-downloads NDK
    multidex=True,
    proguard=True,
    proguardconfig={
        'rules': ['proguard-rules.pro'],
        'optimize': True
    },
    sign=True,
    signconfig={
        'path': 'release.keystore',
        'alias': 'mykey',
        'password': 'mypassword'
    },
    versioncode=2,
    versionname="1.0.1",
    verbose=True
)

apk_path = builder.build("./output")

    'alias': 'mykey',                # Key alias
    'password': 'mypassword',        # Key password

SDK/NDK Management

AndroBuilder automatically manages SDK and NDK installations:

Automatic Download

# Downloads SDK 34 automatically
builder = Builder(path="./MyApp", sdk="34")

# Downloads NDK 25.1.8937393 automatically
builder = Builder(path="./MyApp", sdk="34", ndk="25.1.8937393")

SDKs are installed in: <project>/.androbuilder/sdk/ NDKs are installed in: <project>/.androbuilder/ndk/

Using Existing SDK/NDK

# Use existing SDK
builder = Builder(path="./MyApp", sdk="/path/to/android-sdk")

# Use existing NDK
builder = Builder(path="./MyApp", ndk="/path/to/android-ndk")

SDK Detection

AndroBuilder automatically detects SDKs in:

• $ANDROID_HOME
• $ANDROID_SDK_ROOT
• ~/Android/Sdk
• ~/Library/Android/sdk
• <project>/.androbuilder/sdk

Examples

Basic App

from androbuilder import Builder

builder = Builder(
    path="./HelloWorld",
    sdk="34",
    versionname="1.0.0",
    verbose=True
)

apk = builder.build("./output")

App with Native Code

from androbuilder import Builder

builder = Builder(
    path="./NativeApp",
    sdk="34",
    ndk="25.1.8937393",
    verbose=True
)

apk = builder.build("./output")

Release Build

from androbuilder import Builder

builder = Builder(
    path="./MyApp",
    sdk="34",
    proguard=True,
    proguardconfig={'rules': ['proguard-rules.pro']},
    sign=True,
    signconfig={
        'path': 'release.keystore',
        'alias': 'release',
        'password': 'release123'
    },
    versioncode=10,
    versionname="1.0.9",
    optimize=True
)

apk = builder.build("./release")

Large App with Multi-DEX

from androbuilder import Builder

builder = Builder(
    path="./LargeApp",
    sdk="34",
    multidex=True,
    minsdkversion=21,
    verbose=True
)

apk = builder.build("./output")

Error Handling

from androbuilder import Builder, BuildError, SDKError

try:
    builder = Builder(path="./MyApp", sdk="34")
    apk = builder.build("./output")
except SDKError as e:
    print(f"SDK error: {e}")
except BuildError as e:
    print(f"Build error: {e}")

Requirements

• Python 3.7+
• Java JDK 8+ (for javac and keytool)
• Internet connection (for SDK/NDK downloads)
