引入了安卓sdk,

打包时是不是不能加混淆？

加入混淆时报错：

看官方demo中build.gradle中配置：

release {

minifyEnabled false

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

}

是不启用混淆的。

----------------------------------------------

混淆中已加入代码：-keepclass com.easyar.** {*;}

-----------------------------------------

所以是不是不能加混淆？？？？

29日再次测试报错如下：

JNI DETECTED ERROR IN APPLICATION: JNI GetLongField called with pending exception 'java.lang.NoSuchFieldError' thrown in boolean cn.easyar.CameraFrameStreamer.attachCamera(cn.easyar.CameraDevice):-2
