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);
}
