推荐答案

也许你可以的查询PackageManager 系统是否包含能够响应ACTION_CALL和ACTION_SENDTO意图的任何组成部分？您可能需要添加电话：和smsto：计划中的URI

Maybe you can query the PackageManager whether the system contains any component that can respond to ACTION_CALL and ACTION_SENDTO intents? You might need to add the "tel:" and "smsto:" scheme in the URI.
