Ta的回复 ：hello，我想用android core版本的本地识图，我的core版本的demo跑通后，我点击core 文档里的前往 “DuMix AR官网”文字，在跳转的页面里有个识别图管理，然后我上传一张识别图，点了“下载识别跟踪特征库”，得到一个zip包，里面有三个文件夹“feature，image，model”，我把feature文件夹下的文件拷到“assets/算法模型(可直接放置到手机中)/本地试图”文件夹下，然后重新跑demo，扫自己上传的识别图反馈的结果是未匹配到特征库，请问我这样做有哪些问题，正确应该怎么做？  

Ta的回复 ：我的离在线语音合成也出现这个问题

Ta的回复 ：这个是语音合成sdkdemo里报的错，这是不是也是  28编译产物在android9.0上运行的问题 --------- beginning of crash E/AndroidRuntime: FATAL EXCEPTION: Thread-28 Process: com.baidu.tts.sample, PID: 413

Ta的回复 ：对的，直接用demo跑的，只是编译的依赖环境改变，编译版本，target都是28，我的测试机是华为 mate 9 Pro

Ta的回复 ：（1） 我跑的是     “语音合成”  的demo （2）我周五下的，应该是最新的sdk （3）我修改了  1、 gradle-wrapper.properties 里的变量 我改成distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip；  2、外层 build.gradle  里的配置   我改成classpath 'com.android.tools.build:gradle:3.3.2'；     3、主model 里build.gradle   compileSdkVersion 28,targetSdkVersion 28

Ta的回复 ：我刚刚就只是把  compileSdkVersion 28、targetSdkVersion 28改成 compileSdkVersion 27、targetSdkVersion 27，这样是正常的，没有下面的问题

Ta的回复 ：对的，是这样的
