在混淆代码是，报如下错误，
can't find referenced method 'void sendBroadcast(android.content.Intent)'

如果不混淆，是找得到的，而且在混淆配置文件里面加了-dontwarn android.content.** -keep class android.content.** {*;}

在混淆代码是，包如下错误，如果不混淆，是找得到的，而且在混淆配置文件proguard-rules.pro里面加了-dontwarn java.content.** -keep class java.content.** {*;}
can't find referenced method 'void sendBroadcast(android.content.Intent)'

混淆添加的不正确：Android 4大组件，view，序列化类，枚举，监听方法不能混淆，正确混淆格式如下
#---------------------------------1.实体类---------------------------------
#如：-keep class com.ex..entity.** { ; }
#---------------------------------2.第三方包-------------------------------
#如eventbus
-keepclassmembers class * {
@ org.greenrobot.eventbus.Subscribe ;
}
-keep enum org.greenrobot.eventbus.ThreadMode {*; }
#如gson
-keep class com.google.gson.stream.** { *; }

#如glide
-keep public class * implements com.bumptech.glide.module.GlideModule
-keep public enum com.bumptech.glide.load.resource.bitmap.ImageHeaderParser$** {
[] $VALUES;
public *;
}
#如bugly
-dontwarn com.tencent.bugly.
-keep public class com.tencent.bugly.**{*;}
如#rocoofix
-keep class com.dodola.rocoofix.** {*;}
-keep class com.lody.legend.** {*;}
-keep class com.AMBE.** {*;}
#如okhttp
-dontwarn okhttp3.**
-keep class okhttp3.**{*;}
#如okio
-dontwarn okio.**
-keep class okio.**{*;}
#---------------------------------3.与js互相调用的类------------------------
#如-keepclasseswithmembers class com.demo.login.bean.ui.MainActivity$JSInterface {

#---------------------------------4.反射相关的类和方法-----------------------
#如-keep class com.baolan.blrecode.patch.** {*;}

You shouldn't add any -keep options for this issue; the Android SDK already specifies the basic Android-related -keep options for you.
