AndroidAnnotations:导出后转换Json时出现@Rest错误

标签: rest proguard android-annotations

我有这些课程:

public class OfferList {
   public List<Offer> offers;
}

public class Offer {
    public String offer_id;
    public String group_id;
    public String n_hours;
    public boolean is_new;
}

并定义了这项服务:

@Rest(rootUrl = "http://MYURL/json", converters = { GsonHttpMessageConverter.class })
//if defined, the url will be added as a prefix to every request
public interface EscolasPertoDeMimRESTService {

    @Get("/offers/{user_id}/{date}")
    @Accept(MediaType.APPLICATION_JSON)
    OfferList getOffers(String user_id, long date);
}

这里叫做:

(...)
@RestService
    OfferRestService offersService;

(...)
@Background
void loadListItems() {
    mLoadingOffers = true;
    showProgressDialog();

    OfferList ol = null;
    try {
        ol = offersService.getOffers(myPrefs.userID().get(), myPrefs.lastCheckedForOffers().get());

        showDebug("ol.offers.size(): " + ol.offers.size()); //OK shows ol.offers.size(): 24

        Offer o = ol.offers.get(0); //After exporting: Crash
    showDebug("ol.offers[0].group_id" + o.group_id);

    } catch (Exception e) {
        showDebug(e.getMessage()); //After exporting shows: "com.google.gson.internal.StringMap cannot be cast to com.humihara.escolaspertodemim.Offer"
    }

    setupAdapter(ol);
    mLoadingOffers = false;
}
(...)

在调试中一切正常,但是当我导出并签名时,应用程序崩溃。

发送GET并且来自服务器的响应是有效的JSON商品列表。 显然,我得到的结果是带有StringMap的OfferList而不是Offer(s)。

这是我的proguard-project.txt(我使用的是android sdk默认加上这些):

-keep public class com.humihara.escolaspertodemim.** { *; }
-keep public class org.springframework.** { *; }
-keep public class com.google.gson.** { *; }
-keep public class com.google.ads.** { *; }
-keep public class com.androidannotations.** { *; }
-keep public class org.acra.** { *; }

-keep public class * extends android.support.v4.app.FragmentActivity

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet); }
-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int); }

-dontwarn org.simpleframework.**
-dontnote org.simpleframework.**

-dontwarn org.codehaus.jackson.**
-dontnote org.codehaus.jackson.**

-dontwarn com.fasterxml.jackson.**
-dontnote com.fasterxml.jackson.**

-dontwarn com.google.code.rome.**
-dontnote com.google.code.rome.**

-dontwarn org.apache.commons.httpclient.**
-dontnote org.apache.commons.httpclient.**

我搜索了邮件列表和stackoverflow,在那里我获取了proguard的额外定义,但现在我不知道还能做什么。 有人可以告诉我我的代码或proguard-project.txt中必须更改哪些内容才能使其正常工作?

更新

检查Jackson Json parser returns nulls on all object members on Android after optimizing with Proguard

我想我错过了:

-dontskipnonpubliclibraryclassmembers

默认的android proguard定义:

-dontskipnonpubliclibraryclasses

我并没有注意到他们的表情不一样。

我最终得到了这个proguard-project.txt:

-keepattributes Signature,RuntimeVisibleAnnotations,AnnotationDefault

-dontskipnonpubliclibraryclassmembers

-keep class com.humihara.escolaspertodemim.** { *; }

-keep public class * extends android.support.v4.app.FragmentActivity

-dontwarn org.simpleframework.**
-dontnote org.simpleframework.**

-dontwarn org.codehaus.jackson.**
-dontnote org.codehaus.jackson.**

-dontwarn com.fasterxml.jackson.**
-dontnote com.fasterxml.jackson.**

-dontwarn com.google.code.rome.**
-dontnote com.google.code.rome.**

-dontwarn org.apache.commons.httpclient.**
-dontnote org.apache.commons.httpclient.**

现在一切正常。

对于使用反射来访问注释的代码,您应该保留注释:

-keepattributes *Annotation*
