当您使用ProGuard时，您必须始终解决所有警告，以便能够进一步处ç†æž„建。

这些警告告诉您库引用了一些代ç ï¼Œå¹¶ä¸”没有相关的æºã€‚è¿™å¯èƒ½ä¹Ÿå¯èƒ½ä¸ä¼šã€‚è¿™å–决于是å¦æœ‰é—®é¢˜çš„代ç è¢«è°ƒç”¨ã€‚

在这ç§æƒ…况下，库引用了一些代ç ï¼Œä½†ä¼¼ä¹Žæ²¡æœ‰è°ƒç”¨ä»£ç ï¼ˆä¾‹å¦‚，因为您没有添加其他库）。在这ç§æƒ…况下，将-dontwarn规则添加到proguard-rules.pro文件中。

您使用Retrofitå’ŒPicasso库。å°è¯•æ·»åŠ ä»¥ä¸‹è§„则：

-dontwarn okio.**
-dontwarn retrofit.**
-keep class retrofit.** { *; }
-keepclassmembers,allowobfuscation interface * {
    @retrofit.http.** <methods>;
}

-dontwarn com.squareup.okhttp.**

它å¯èƒ½ä¼šè§£å†³æ‚¨çš„问题。

请注æ„，您å¯èƒ½ä¼šåœ¨è¿è¡Œæ—¶é‡åˆ°æ›´å¤šé—®é¢˜ï¼Œå°¤å…¶æ˜¯å½“这些库中的任何库使用å射并且代ç æ”¶ç¼©å’Œ/或混淆时。那么你很å¯èƒ½éœ€è¦æ›´å¤šçš„ProGuard规则用于其他库。

修改 è¦è§£å†³ä¸ŽRxJava相关的警告，请添加此ä¾èµ–项：

// ProGuard rules for RxJava
compile 'com.artemzin.rxjava:proguard-rules:1.1.1.0'

它为RxJava添加了必è¦çš„ProGuard规则。

我é‡åˆ°äº†åŒæ ·çš„问题，并通过å‘proguard-project.txt添加以下文字解决了这个问题：

# for transformClassesAndResourcesWithProguardForRelease
# -- Picasso --
-dontwarn com.squareup.picasso.**
# -- OkHttp --
-dontwarn com.squareup.okhttp.internal.**
# -- Apache Commons --
-dontwarn org.apache.commons.logging.**
-ignorewarnings
-keep class *
{
    public private *;
}
