the class LoadedPlugin method createAssetManager.

Example 95 with AssetManager

use of android.content.res.AssetManager in project AndroidLife by CaMnter.

the class ResourcesManager method createResources.

/**
 * 反射创建 一个 复合资源
 *
 * --------------------------------------------------------------------------------------------
 *
 * 通过反射调用
 * AssetManager # addAssetPath(String path)
 *
 * 然后得到的 AssetManager
 * 直接 new Resources
 *
 * --------------------------------------------------------------------------------------------
 *
 * 1. 拿到宿主上的 AssetManager，低与 5.0.0 直接反射创建出来
 * 2. 反射调用 AssetManager # addAssetPath(String path)，添加 当前插件 Apk
 * -  这样 AssetManager 生成的 Resources 就有 当前插件 和 宿主 的资源
 * 3. 获取之前加载过的 Apk 内存形式 - LoadedPlugin，然后循环调用 AssetManager # addAssetPath(String path)
 * -  这样 AssetManager 生成的 Resources 就有 当前插件 、之前加载过的插件 和 宿主 的资源
 * 4. 由于 MiUi, Vivo, Nubia 等的资源实现类不一样，在进行 new Resources 的时候，需要适配
 *
 * --------------------------------------------------------------------------------------------
 *
 * @param hostContext hostContext
 * @param apk apk
 * @return Resources
