1.先贴AndroidManifest.xml

内容如下：

<?xml version="1.0" encoding="UTF-8"?>

<manifest

android:compileSdkVersion="30"

android:compileSdkVersionCodename="11"

android:versionCode="1679077605"

android:versionName="17.1"

platformBuildVersionName="11"

xmlns:android="http://schemas.android.com/apk/res/android">

<uses-sdk

android:targetSdkVersion="30"/>

<uses-feature

<uses-feature

<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>

<application

android:allowBackup="true"

android:fullBackupContent="@xml/backup"

android:fullBackupOnly="true"

android:hardwareAccelerated="true"

android:icon="@mipmap/icon"

android:isGame="true"

android:label="@string/appName"

android:theme="@android:style/Theme.NoTitleBar.Fullscreen">

<activity

android:alwaysRetainTaskState="true"

android:label="@string/iconName"

android:launchMode="singleTop"

android:name="org.renpy.android.PythonSDLActivity"

android:screenOrientation="sensorLandscape">

</activity>

<receiver

</receiver>

<meta-data

android:value="3.0.0"/>

<activity

android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|screenSize"

android:name="com.android.billingclient.api.ProxyBillingActivity"

android:theme="@android:style/Theme.Translucent.NoTitleBar"/>

android:stateNotNeeded="true"

android:theme="@style/Theme.PlayCore.Transparent"/>

<service

android:enabled="false"

android:exported="true"

android:name="com.google.android.play.core.assetpacks.AssetPackExtractionService">

<meta-data

android:name="com.google.android.play.core.assetpacks.versionCode"

android:value="11000"/>

</service>

<service

android:enabled="false"

android:exported="false"

android:name="com.google.android.play.core.assetpacks.ExtractionForegroundService"/>

</application>

</manifest>

可以看到启动入口

org.renpy.android.PythonSDLActivity

如果没有经过特殊定制，renPy打包apk的时候生成的自动入口都是它；

2. 通过 JEB打开android 的apk 可以看到目录结构如下：

3.对象创建

public PythonSDLActivity() {this.mPresplash = null;this.mAllPacksReady = false;this.mAssetPackManager = null;this.mProgressBar = null;this.waitForWifiConfirmationShown = false;this.assetPackStates = new HashMap();this.mOldProgress = 0L;this.wakeLock = null;this.mActivityResultRequestCode = -1;this.mActivityResultResultCode = -1;this.mActivityResultResultData = null;
}

4.实际和renPy相关的入口 PythonSDLActivity#onCreate

@Override  // org.libsdl.app.SDLActivity
protected void onCreate(Bundle bundle0) {1. 日志记录与父类调用Log.v("python", "onCreate()");super.onCreate(bundle0);
2.调用 Store.create() 方法，初始化应用内购买（IAP）模块。不用关注Store.create(this);boolean z = true;
3. 设置 SurfaceView 格式PythonSDLActivity.setSurfaceViewFormat(1);if(Constants.assetPacks.length > 0) {
5. 处理 Asset Pack 下载（Google Play Asset Delivery）AssetPackManager assetPackManager0 = AssetPackManagerFactory.getInstance(this);this.mAssetPackManager = assetPackManager0;assetPackManager0.registerListener(this);String[] arr_s = Constants.assetPacks;for(int v = 0; v < arr_s.length; ++v) {String s = arr_s[v];if(!this.checkPack(s)) {Log.i("python", "fetching: " + s);this.mAssetPackManager.fetch(Collections.singletonList(s));z = false;}}}
6. 预加载启动画面 (Presplash) 或下载进度条this.mAllPacksReady = z;Bitmap bitmap0 = this.getBitmap((z ? "android-presplash" : "android-downloading") + ".png");if(bitmap0 == null) {bitmap0 = this.getBitmap((z ? "android-presplash" : "android-downloading") + ".jpg");}
7. 显示 Presplash 图像if(bitmap0 != null) {ImageView imageView0 = new ImageView(this);this.mPresplash = imageView0;imageView0.setBackgroundColor(bitmap0.getPixel(0, 0));this.mPresplash.setScaleType(ImageView.ScaleType.FIT_CENTER);this.mPresplash.setImageBitmap(bitmap0);PythonSDLActivity.mLayout.addView(this.mPresplash, new ViewGroup.LayoutParams(-1, -1));}
8. 显示下载进度条（如果资源未完全准备好）if(!this.mAllPacksReady) {RelativeLayout.LayoutParams relativeLayout$LayoutParams0 = new RelativeLayout.LayoutParams(-1, 20);relativeLayout$LayoutParams0.addRule(12);relativeLayout$LayoutParams0.leftMargin = 20;relativeLayout$LayoutParams0.rightMargin = 20;relativeLayout$LayoutParams0.bottomMargin = 20;this.mProgressBar = new ProgressBar(this, null, 0x1010078);PythonSDLActivity.mLayout.addView(this.mProgressBar, relativeLayout$LayoutParams0);}
}

功能
描述

onCreate() 是整个游戏/应用的入口点
游戏引擎集成
继承自 SDLActivity，初始化图形、音频等底层系统
资源管理
支持 Google Play Asset Delivery，动态下载大资源包
UI 展示
加载 presplash 图片或下载进度条
日志与调试
输出关键流程信息，便于调试资源加载和初始化过程
