Android Proguard&FirebaseListAdapter发生冲突 [英] Android Proguard & FirebaseListAdapter Are conflicting

问题描述

晚上好

我花了几个小时试图了解发生了什么.这是这种情况:

I have spent a couple of hours trying to understand whats going on. This is the situation:

制作了一个应用程序，在调试模式下可以正常工作，但是发布模式在FirebaseListAdapter上给了我错误:

Made an app, works fine in debug mode, but release mode gives me errors on the FirebaseListAdapter:

    DatabaseReference ref = FirebaseDatabase.getInstance().getReference("a/");
    mAdapter = new FirebaseListAdapter<Acties>(activity, Acties.class, R.layout.list, ref) {

        @Override
        public void populateView(View v, Acties model, int position) {
            ((TextView)v.findViewById(R.id.textView1)).setText(model.getWinkel());
            ((TextView)v.findViewById(R.id.textView2)).setText(model.getBericht());
            ((TextView)v.findViewById(R.id.textView3)).setText(model.getExpdate());
        }
    };

FirebaseListAdapter使用Acties.class作为吸气剂.

FirebaseListAdapter uses Acties.class as getters.

public class Acties {
private String bericht;
private String winkel;
private String expdate;

public Acties() {
}

public Acties(String bericht, String expdate, String winkel) {
    this.bericht = bericht;
    this.winkel = winkel;
    this.expdate = expdate;
}

public String getBericht() {
    return bericht;
}

public String getExpdate() {
    return expdate;
}

public String getWinkel() {
    return winkel;
}

}

我将每个字符串都编辑为public而不是private.(根据此答案: https://stackoverflow.com/a/37744290/6510329 )

I edited every string to public instead of private. (According to this answer: https://stackoverflow.com/a/37744290/6510329)

这修复了应用程序崩溃的问题，但是现在我得到了一个空列表.我现在可以看到ListView，但是其中没有充满从数据库中获取的信息.

This fixed the crash of the app, but now i got an empty list. I can see the ListView now, but it is not filled with the info grabbed from my database.

这是怎么回事?由于其释放模式，我看不到错误.

What is going on? I cannot see the error because of its release mode..

我还在我的课程中添加了@Keep，但仍然无法正常工作.(答案: https://stackoverflow.com/a/41141406/6510329 )

I have also added @Keep in my classes, and it still did not work. (Answer: https://stackoverflow.com/a/41141406/6510329)

将此代码添加到proguard-rules文件中:

Added this code to proguard-rules file:

-keep class com.firebase.** { *; }
-keep class org.apache.** { *; }
-keepnames class com.fasterxml.jackson.** { *; }
-keepnames class javax.servlet.** { *; }
-keepnames class org.ietf.jgss.** { *; }
-dontwarn org.w3c.dom.**
-dontwarn org.joda.time.**
-dontwarn org.shaded.apache.**
-dontwarn org.ietf.jgss.**

这给了我与以前完全相同的内容，现在可以看到一个列表，但文本视图为空.(答案: https://stackoverflow.com/a/26274623/7157263 )

Which gave me the exact same as before, a list now visible, but with empty textviews.. (Answer: https://stackoverflow.com/a/26274623/7157263)

添加了以下规则以保护自己:

Added these rules to proguard:

-keepattributes Signature
-keepattributes *Annotation*

仍然没有任何改变.每个Firebase功能都能完美运行.除了FirebaseListAdapter/populateview方法

Still nothing changed.. EVERY firebase function works perfect. EXCEPT for the FirebaseListAdapter/populateview method

感谢阅读所有这些内容，我现在要休息一下并尽快返回，也许这会给我一些天才"的时刻

Thanks for reading all of this, im going to take a break now and get back to it soon, maybe that will give me some kind of "genius" moment

推荐答案

您可以添加指令以使ProGuard保留 Acties 的方法和字段.只需将其添加到您的ProGuard文件中即可:

You can add a directive to make ProGuard preserve the methods and fields of Acties. Just add this to your ProGuard file:

-keep class com.yourproject.Acties { *; }

其中 com.yourproject.Acties 是 Acties 类的全名(带有包).

where com.yourproject.Acties is the full name (with package) of the Acties class.

或者，您可以使用 @Keep 注释 Acties 类，这使ProGuard在进行模糊处理/优化时保持不变.

Alternatively, you can annotate the Acties class with @Keep, which makes ProGuard leave it unchanged while applying obfuscation/optimizations.
