Note: com.google.android.gms.dynamite.DynamiteModule accesses a declared field 'MODULE_ID' dynamically
      Maybe this is program field 'com.google.android.gms.dynamite.descriptors.com.google.android.gms.flags.ModuleDescriptor  java.lang.String MODULE_ID; '
Note: com.google.android.gms.dynamite.DynamiteModule accesses a declared field 'MODULE_VERSION' dynamically

Note: com.google.gson.internal.UnsafeAllocator accesses a declared field 'theUnsafe' dynamically
Note: the configuration explicitly specifies 'sun.misc.Unsafe' to keep library class 'sun.misc.Unsafe'
Note: the configuration explicitly specifies 'org.xmlpull.v1.**' to keep library class 'org.xmlpull.v1.XmlPullParser'
Note: the configuration explicitly specifies 'org.xmlpull.v1.**' to keep library class 'org.xmlpull.v1.XmlPullParserException'

Note: there were 15 references to unknown classes.
      You should check your configuration for typos.
      (http://proguard.sourceforge.net/manual/troubleshooting.html#unknownclass)
Note: there were 5 library classes explicitly being kept.
      You don't need to keep library classes; they are already left unchanged.
      (http://proguard.sourceforge.net/manual/troubleshooting.html#libraryclass)
Note: there were 11 unresolved dynamic references to classes or interfaces.
      You should check if you need to specify additional program jars.
      (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclass)
Note: there were 4 accesses to class members by means of introspection.
      You should consider explicitly keeping the mentioned class members
      (using '-keep' or '-keepclassmembers').
      (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclassmember)

Warning: there were 1 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)

【问题讨论】：

执行此操作时出错 -> 读取库 jar [/Users/harsh/Development/sdk/platforms/android-25/optional/org.apache.http.legacy.jar]

【参考方案1】：

我通过在 proguard 中添加几行来解决此错误。我在 gradle 中使用 twitter 库。

-keepattributes *Annotation*
-keepattributes SourceFile,LineNumberTable
-keep public class * extends java.lang.Exception
-printmapping mapping.txt
-keep class com.crashlytics.**  *; 
-dontwarn com.crashlytics.**

-dontwarn com.squareup.okhttp.**
-dontwarn com.google.appengine.api.urlfetch.**
-dontwarn rx.**
-dontwarn retrofit.**
-keepattributes Signature
-keepattributes *Annotation*
-keep class com.squareup.okhttp.**  *; 
-keep interface com.squareup.okhttp.**  *; 
-keep class retrofit.**  *; 
-keepclasseswithmembers class * 
    @retrofit.http.* <methods>;

【参考方案2】：

确保升级到最新的 Gradle 版本以使用 annotationProcessor 语法：

dependencies 
    compile "com.google.dagger:dagger:2.9"
    annotationProcessor "com.google.dagger:dagger-compiler:2.9"
    provided 'javax.annotation:jsr250-api:1.0'
