VirtualAPK的简单使用

VirtualApk引入步骤：

一、宿主应用引入VirtualApk

1、在项目的build.gradle文件中加入依赖:

dependencies {
    classpath 'com.didi.virtualapk:gradle:0.9.8.6'
}

完整的gradle文件如下：

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

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
        classpath 'com.didi.virtualapk:gradle:0.9.8.6'
        

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

2、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'
}

完整的gradle文件如下:

    apply plugin: 'com.android.application'
	apply plugin: 'com.didi.virtualapk.host'
	
	android {
	    compileSdkVersion 28
	    defaultConfig {
	        applicationId "com.wangyz.virtualapk.host"
	        minSdkVersion 21
	        targetSdkVersion 28
	        versionCode 1
	        versionName "1.0"
	        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
	    }
	    buildTypes {
	        release {
	            minifyEnabled false
	            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
	        }
	    }
	}

	dependencies {
	    implementation fileTree(dir: 'libs', include: ['*.jar'])
	    implementation 'com.android.support:appcompat-v7:28.+'
	    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
	    testImplementation 'junit:junit:4.12'
	    androidTestImplementation 'com.android.support.test:runner:1.0.1'
	    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
	
	    implementation 'com.didi.virtualapk:core:0.9.8'
	}

3、新建项目的Application，继承自Application,并在attachBaseContext方法中初始化

public class App extends Application{

    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        PluginManager.getInstance(base).init();
    }
}

4、在AndroidManifest.xml中引入自定义的Application

<application
    android:name=".App"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

5、申明权限

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

二、Plugin中引入VirtualApk

1、在项目的build.gradle文件中加入依赖:

dependencies {
    classpath 'com.didi.virtualapk:gradle:0.9.8.6'
}

完整的gradle文件如下:

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

buildscript {
    
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
        classpath 'com.didi.virtualapk:gradle:0.9.8.6'
        

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

2、在app的build.gradle文件中加入依赖:

apply plugin: 'com.didi.virtualapk.plugin'

virtualApk{
    packageId = 0x6f
    targetHost = '../../VirtualAPKHost/app'//宿主应用的app模块路径
    applyHostMapping = true
}

3、在app的build.gradle文件中加入签名配置

signingConfigs{
        release{
            storeFile file('../../android.keystore')
            storePassword "android"
            keyAlias "android"
            keyPassword "android"
        }
    }

	buildTypes {
    release {
        minifyEnabled false
        signingConfig signingConfigs.release
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

完整的gradle文件如下:

apply plugin: 'com.android.application'
apply plugin: 'com.didi.virtualapk.plugin'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.wangyz.virtualapk.plugin"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    signingConfigs{
        release{
            storeFile file('../../android.keystore')
            storePassword "android"
            keyAlias "android"
            keyPassword "android"
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            signingConfig signingConfigs.release
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.+'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

virtualApk{
    packageId = 0x6f
    targetHost = '../../VirtualAPKHost/app'
    applyHostMapping = true
}

注意：Plugin应用的资源文件不能和宿主的资源文件重名，否则在生成插件APK时会报错:

建议各模块资源命名以模块名开头。

4、生成插件APK

打开gradle窗口，双击assemblePlugin，生成APK

文件生成目录：app/build/outputs/plugin/release/

三、在宿主应用中加载插件APK

1、将生成的插件APK推送(通过网络或者adb等)到手机指定路径，如/sdcard/Plugin.apk。

2、在宿主应用中加载APK

private static final String PLUGIN_PACKAGE_NAME = "com.wangyz.virtualapk.plugin";
private static final String PLUGIN_NAME = "com.wangyz.virtualapk.plugin.MainActivity";

private void loadPlugin() {
    try {
        String pluginPath = Environment.getExternalStorageDirectory().getAbsolutePath().concat("/Plugin.apk");
        File plugin = new File(pluginPath);
        PluginManager.getInstance(this).loadPlugin(plugin);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

3、调用APK中的Activity

public void loadPlugin(View view) {
    if (PluginManager.getInstance(this).getLoadedPlugin(PLUGIN_PACKAGE_NAME) == null) {
        Toast.makeText(getApplicationContext(), "未加载插件", Toast.LENGTH_SHORT).show();
        return;
    }
    Intent intent = new Intent();
    intent.setComponent(new ComponentName(PLUGIN_PACKAGE_NAME, PLUGIN_NAME));
    startActivity(intent);
}
