Android 利用奇虎DroidPlugin实现插件化

集成起来很简单.在这里我也只是尝尝鲜而已.实际项目中并没有用到

开始集成:

1. 我们只需要将Droid Plugin当作一个lib工程应用到主项目中，然后：

2. 在AndroidManifest.xml中使用插件的com.morgoo.droidplugin.PluginApplication：

3. 如果你使用自定义的Application，那么你需要在自定义的Application class onCreate和attachBaseContext方法中添加如下代码：

   @Override
   public void onCreate() {
       super.onCreate();
       //这里必须在super.onCreate方法之后，顺序不能变
       PluginHelper.getInstance().applicationOnCreate(getBaseContext());
   }
   
   @Override
   protected void attachBaseContext(Context base) {
       PluginHelper.getInstance().applicationAttachBaseContext(base);
       super.attachBaseContext(base);
   }
   

4. 修改 Libraries\DroidPlugin\build.gradle 的 defaultConfig 配置中 authorityName 的值（建议改为自己的包名+标识，防止跟其它本插件使用者冲突）

5. 集成完成。

把我们的plugin apk(简单的helloworld都可以)放到指定目录.

安装一个插件:

PluginManager.getInstance().installPackage(file.getAbsolutePath(), PackageManagerCompat.INSTALL_REPLACE_EXISTING);

卸载一个插件:

 PluginManager.getInstance().deletePackage(PLUGIN_PACKAGE_NAME, 0);

启动插件:

 PackageManager pm = getPackageManager();
        Intent intent = pm.getLaunchIntentForPackage(PLUGIN_PACKAGE_NAME);
        if (null != intent) {
            startActivity(intent);
        } else {
            Toast.makeText(getApplicationContext(), "插件还未安装", Toast.LENGTH_SHORT).show();
        }
