一、插件化框架选择
DynamicAPK、VirtualApp、DroidPlugin等插件化框架,经过比较选择VirtualAPK支持四大组件,支持插件宿主之间的交互,兼容性强,对Android适配比较好,所以选择它作为插件化框架;优缺点对比可参考博客插件化篇 - 插件化框架对比
二、VirtualAPK集成
VirtualAPK github 地址
2.1 Host APP宿主集成
在项目的build.gradle文件中加入依赖
dependencies {
classpath 'com.didi.virtualapk:gradle:0.9.8.6'
}
在app的build.gradle文件中加入依赖
apply plugin: 'com.didi.virtualapk.host'
dependencies {
implementation 'com.didi.virtualapk:core:0.9.8'
}
新建项目的Application,继承自Application,并在attachBaseContext方法中初始化
public class AppAplication extends Application {
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
PluginManager.getInstance(base).init();
}
}
在AndroidManifest.xml中
<application
android:name=".AppAplication"
...
</application>
混淆文件proguard-rules.pro
-keep class com.didi.virtualapk.internal.VAInstrumentation { *; }
-keep class com.didi.virtualapk.internal.PluginContentResolver { *; }
-dontwarn com.didi.virtualapk.**
-dontwarn android.**
-keep class android.** { *; }
2.2 Plugin APP插件集成
在项目的build.gradle文件中加入依赖
dependencies {
classpath 'com.didi.virtualapk:gradle:0.9.8.6'
}
在app的build.gradle文件中加入依赖
apply plugin: 'com.didi.virtualapk.plugin'
virtualApk{
packageId = 0x6f //插件资源id,避免资源id冲突
targetHost = '../APP_Plug/app_host' //宿主应用的app模块路径
applyHostMapping = true // 【选填】插件编译时是否启用应用宿主的apply mapping
}

三、生成插件APK
插件apk签名配置
signingConfigs {
release {
//keystore文件的存放位置
storeFile file('../debug.keystore')
//keystore密码
storePassword 'android'
//Key别名
keyAlias 'androiddebugkey'
//Key密码
keyPassword 'android'
}
}
buildTypes {
release {
minifyEnabled false
signingConfig signingConfigs.release
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
打开gradle窗口,双击assemblePlugin,生成APK
插件文件
插件apk生成目录:app/build/outputs/plugin/release/
四、在宿主应用中加载插件APK
将插件生成的app_plug-release.apk拷贝到相应的主app目录下,加载代码如下
public class MainActivity extends AppCompatActivity {
private final String TAG = "MainActivity";
boolean isSuccess = false;
@Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE)
== PackageManager.PERMISSION_GRANTED) {
} else {
ActivityCompat.requestPermissions(this, new String[] {
Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE
}, 100);
}
//String pluginPath = Environment.getExternalStorageDirectory().getAbsolutePath().concat("/app_plug-release.apk");
File plugin = new File(this.getFilesDir(), "app_plug-release.apk");
if (plugin.exists()) {
Log.e(TAG, "'exists'");
try {
PluginManager.getInstance(this).loadPlugin(plugin);
isSuccess = true;
} catch (Exception e) {
e.printStackTrace();
}
}
Button viewById = findViewById(R.id.btn_skip);
viewById.setOnClickListener(new View.OnClickListener() {
@Override public void onClick(View view) {
if (isSuccess) {
if (PluginManager.getInstance(MainActivity.this).getLoadedPlugin("com.zj.plugapp")
== null) {
Toast.makeText(getApplicationContext(), "加载插件失败", Toast.LENGTH_SHORT).show();
return;
}
// Given "com.didi.virtualapk.demo" is the package name of plugin APK,
// and there is an activity called `MainActivity`.
Intent intent = new Intent();
intent.setClassName("com.zj.plugapp", "com.zj.plugapp.HomeActivity");
startActivity(intent);
} else {
Toast.makeText(MainActivity.this, "初始化插件失败!", Toast.LENGTH_LONG).show();
}
}
});
}
}
需要注意插件的包名和页面的路径
五、常见的问题
问题一:
由于virtualApk几年没有更新了,对最新的gradle不兼容。
解决:
强制使用以下版本:
https://github.com/didi/VirtualAPK/issues/340
classpath 'com.android.tools.build:gradle:3.1.4'
distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip
问题二:
目前VirtualAPK不支持Gradle插件3.2.1以上版(不支持AndroidX包)
解决:
gradle.properties 文件中:
android.useDexArchive=false
问题三:
编译报错
> Required entry 'plug_activity_home' but got 'notification_template_part_chronometer', This is seems to unsupport the buildToolsRevision: 28.0.0.
解决:
编译版本小等于28+:
compileSdkVersion 28
implementation 'com.android.support:appcompat-v7:28+'
问题四:
运行插件报错
Caused by: android.content.pm.PackageParser$PackageParserException: Package /data/user/0/com.zj.hostapp/files/com.zj.plugapp_20210701095025.apk has no certificates at entry AndroidManifest.xml
解决:
插件签名之后再加载调用
