Warning:there were 107 unresolved references to classes or interfaces. You may need to add missing library jars or update their versions. If your code works fine without the missing classes, you can suppress the warnings with '-dontwarn' options. (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass)
Warning:there were 128 instances of library classes depending on program classes. You must avoid such dependencies, since the program classes will be processed, while the library classes will remain unchanged. (http://proguard.sourceforge.net/manual/troubleshooting.html#dependency)

我尝试了几次清洁和建造，但同样的错误。
答案 0 :(得分：0)
这是因为您的Proguard已启用：
尝试使用以下行更新您的proguard文件：
// org.apache
-dontwarn org.apache.**
// Jackson
-keep class com.fasterxml.jackson.databind.ObjectMapper {
public <methods>;
protected <methods>;
}
-keep class com.fasterxml.jackson.databind.ObjectWriter {
public ** writeValueAsString(**);
}
-keepnames class com.fasterxml.jackson.** { *; }
-dontwarn com.fasterxml.jackson.databind.**
//OkHttp
-dontwarn com.squareup.okhttp.**
// Picasso
-dontwarn com.squareup.picasso.**
//Okio
-dontwarn okio.**
//Joda Time Convert
-dontwarn org.joda.convert.**
这只是为了帮助您修复apk构建过程，但是您必须测试已签名的apk以检查是否存在它应该需要的任何引用，并且由于代码混淆而无法获取。
我建议您阅读proguard手册，并通过troubleshooting修复是否遇到任何问题
