滴滴开源Android插件方案:VirtualAPK
2 宿主App集成方法
(1)在整个工程的build.gradle中添加依赖
dependencies { classpath 'com.android.tools.build:gradle:3.0.1' classpath 'com.didi.virtualapk:gradle:0.9.8.4' // VirtualApk // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files }
(2)在app模块(宿主App模块名,可改名)build.gradle添加插件引用
apply plugin: 'com.didi.virtualapk.host' // VirtualApk build.gradle文件顶部添加
(3)在app模块build.gradle中添加依赖
dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'com.android.support:appcompat-v7:26.1.0' implementation 'com.android.support.constraint:constraint-layout:1.1.3' compile 'com.didi.virtualapk:core:0.9.6' // VirtualApk }
(4)在Application的attachBaseContext中添加PluginManager初始化代码
import com.didi.virtualapk.PluginManager; public class TestApplication extends Application { @Override protected void attachBaseContext(Context base) { super.attachBaseContext(base); long start = System.currentTimeMillis(); PluginManager.getInstance(base).init(); // 主要是这句 Log.d("KLH", "use time:" + (System.currentTimeMillis() - start)); } }
(5)在MainActivity的OnCreate中自动加载插件(这一步的时机可选,也可以是后续再加载),请注意这里加载插件的路径和apk名称,要约定好。
private void loadPlugin() { PluginManager pm = PluginManager.getInstance(this); File apk = new File(Environment.getExternalStorageDirectory(), "test_plugin.apk"); if (apk.exists()) { try { pm.loadPlugin(apk); showToast("插件加载成功!!!"); } catch (Exception e) { e.printStackTrace(); showToast("插件加载异常了。。。"); } } }
(6)启动插件Apk(这里以启动插件中的一个Activity为例)
Intent intent = new Intent(); intent.setClassName("com.klh.testplugin", "com.klh.testplugin.MainActivity"); startActivity(intent);
3 插件App集成方法
插件工程是一个独立的App工程,只不过添加了VirtualAPK相关依赖,并且在编译时需要关联宿主工程目录(为了做一些信息同步与共享库删减)
(1)在整个工程的build.gradle中添加依赖
dependencies { classpath 'com.android.tools.build:gradle:3.0.1' classpath 'com.didi.virtualapk:gradle:0.9.8.4' // VirtualApk // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files }
(2)在app模块的build.gradle中添加依赖
dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'com.android.support:appcompat-v7:26.1.0' implementation 'com.android.support.constraint:constraint-layout:1.1.3' compile 'com.didi.virtualapk:core:0.9.6' // VirtualApk }
(3)在app模块的build.gradle文件末尾中添加插件配置
// VirtualApk apply plugin: 'com.didi.virtualapk.plugin' virtualApk { // 要指定一个不重复的ID来区分插件资源,有效值范围:[0x02, 0x7E] packageId = 0x6a // the package id of Resources. // 宿主App的Application模块(绝对/相对)路径,插件的构建需要依赖此路径 targetHost = '../testAndroid/app' // the path of application module in host project. // 如果插件有引用宿主的类,那么此选项可以确保插件与宿主保持混淆一致 applyHostMapping = true //optional, default value: true. }
(4)编译方法:gradlew clean assemblePlugin
4 安装测试
(1)安装宿主App
(2)将编译好的插件改名与宿主约定一致,推送到指定目录。例如本文的约定路径是:/sdcard/test_plugin.apk
E:\VirtualShare\gitLab\research\05.VirtualApk\VATestPlugin>adb push app\build\outputs\apk\release\app-release-unsigned.apk /sdcard/test_plugin.apk
app\build\outputs\apk\release\app-release-unsigned.apk: 1 file pushed. 0.9 MB/s (27437 bytes in 0.030s)
5 其他
插件不能直接访问宿主App的接口,可采用与宿主App集成相同的aar包来实现数据交互。
