# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in E:\AndroiSdK/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html
# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the Javascript interface
# class:
#-keepclassmembers class fqcn.of.Javascript.interface.for.webview {
# public *;
#}

##---------------Begin: proguard configuration for Gson ----------

# removes such information by default, so configure it to keep all of it.

c.如果你的项目中集成了MPAndroidChart图表，那么也得加上混淆，参考这里，代码如下：

-keep class com.github.mikephil.charting.** { *; } # 确保MPAndroidChart加载动画可用

d.如果你的项目中使用了Webview并且自定义了Javainterface有js交互的，那么需要添加如下混淆代码：

#----------------JS混淆Start---------------------
-keepclassmembers class com.xxxxx.xxx.xxxActivity$MyJavascriptInterface {
public *;
}
-keepattributes *Annotation*
-keepattributes *JavascriptInterface*
#----------------JS混淆End---------------------
