Question

不要轻易判断基于单独的标题，我知道类似的问题已经被问过，但这个问题是一个有点不同。请忍受并通读。

因此，我已经定义了一个BaseUser类，如下所示：

import android.support.annotation.NonNull;
import android.util.Log;

import com.google.android.gms.tasks.OnFailureListener;
import com.google.android.gms.tasks.OnSuccessListener;
import com.google.firebase.auth.FirebaseAuth;
import com.google.firebase.firestore.DocumentSnapshot;
import com.google.firebase.firestore.Exclude;
import com.google.firebase.firestore.FirebaseFirestore;
import com.google.firebase.storage.FirebaseStorage;

import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.Callable;

public class BaseUser
{
    private static final String TAG = "BaseUser";

    /**
     * Firebase Authentication and Database
     */
    protected FirebaseAuth auth;
    protected FirebaseFirestore db;
    protected FirebaseStorage st;

    /**
     * General BaseUser Info
     */
    private String firstName;
    private String lastName;
    private List<String> phones;
    private List<String> emails;
    private List<AddressLocation> addresses;

    public BaseUser()
    {
        auth = FirebaseAuth.getInstance();
        db = FirebaseFirestore.getInstance();
        st = FirebaseStorage.getInstance();
        phones = new ArrayList<>();
        emails = new ArrayList<>();
        addresses = new ArrayList<>();
    }

    /**
     * Getters
     */

    public final String getFirstName()
    {
        return firstName;
    }

    public final String getLastName()
    {
        return lastName;
    }

    @Exclude
    public final List<String> getPhones()
    {
        return phones;
    }

    @Exclude
    public final List<String> getEmails()
    {
        return emails;
    }

    @Exclude
    public final List<AddressLocation> getAddresses()
    {
        return addresses;
    }

    /**
     * Special Getters
     */

    @Exclude
    public final String getPhone(int index)
    {
        return phones.get(index);
    }

    // SimilarStuff


    /**
     * Setters
     */

    @Exclude
    public final void setFirstName(String firstName)
    {
        this.firstName = firstName;
    }

    @Exclude
    public final void setLastName(String lastName)
    {
        this.lastName = lastName;
    }

    @Exclude
    public final void setPhones(List<String> phones)
    {
        this.phones = phones;
    }

    @Exclude
    public final void setEmails(List<String> emails)
    {
        this.emails = emails;
    }

    @Exclude
    public final void setAddresses(List<AddressLocation> addresses)
    {
        this.addresses = addresses;
    }

    /**
     * Special Setters
     */

    @Exclude
    public final void addPhone(String phone)
    {
        this.phones.add(phone);
    }

    // SimilarStuff

    /**
     * Authentication
     */
    @Exclude
    public final boolean isLoggedIn()
    {
        assert(auth != null);
        return (auth.getCurrentUser() != null);
    }

    /**
     * Shared BaseUser Instance
     */

    protected static BaseUser holder = new BaseUser();

    @Exclude
    public static BaseUser getInstance()
    {
        assert(holder != null);
        return holder;
    }

    /**
     * Database
     */

    @Exclude
    protected final void downloadUser(final Callable<Void> callback)
    {
        // Doesn't get called for now.
    }

    @Exclude
    protected final void uploadUser()
    {
        assert(isLoggedIn());
        db.collection("users").document(auth.getCurrentUser().getUid()).set(this).addOnFailureListener(new OnFailureListener()
        {
            @Override
            public void onFailure(@NonNull Exception e)
            {
                Log.wtf(TAG, "Failed to write user data");
            }
        });
    }
}

，你可以看到，类定义了几个阵列的沿着一对夫妇串。包括绝对没有别的可能有setWallpaper。另外，如您所见，为查找错误的来源，我从字面上排除了所有函数（是的，即使它们不是以set或get开始）读取两个简单字符串的函数。

现在，当调用uploadUser方法时，出现以下错误：

我grepped我的文件夹中找出包括setWallpaper，我发现以下内容：

shell$ grep -rnw "setWallpaper" .
Binary file ./authentication/build/intermediates/transforms/instantRun/AppName/debug/0/com/companyname/projectname/authentication/ResetPasswordActivity.class matches

Binary file ./authentication/build/intermediates/transforms/dexMerger/AppName/debug/1/classes.dex matches

因此BaseUser与此setWallpaper毫无关系。它仅与我的UI活动有关（无论如何我都没有明确使用它）。

我尝试过的事情：

如上所述，除了用于简单String的2个setter之外，不包括所有内容。
我认为让BaseUser类本身处理Firestore可能会引起问题，因此我尝试从类外部进行同样的操作。一样。
我尝试使用Firebase数据库而不是Firestore。一样。
还有一些其他的类继承BaseUser。我已经全部禁用了。相同。（我什至不确定为什么会有问题！）

其他信息

我不确定以下内容是否相关，但是考虑到该错误的怪异性质，无论如何我都会将其扔到这里。

类BaseUser是在被称为一个单独的模块user。处理身份验证的UI类（在上面的grep输出中列出）位于称为authentication的单独模块中。第三模块core定义了火力库依赖并从必要的信息google-services.json。

我还必须提到，与模块的这种构造我可以使用火力地堡认证就好了。只有Firestore或Firebase数据库有问题。

问题

现在，为什么人人都在抱怨Firestore什至没有我班上的二传手？我该如何解决？

我试图两个不同的东西现在：

我试图上载一个简单的地图，而不是，所以uploadUser函数内部添加以下：

protected final void uploadUser()
{
    assert(isLoggedIn());
    Map<String, Object> city = new HashMap<>();
    city.put("name", "Los Angeles");
    city.put("state", "CA");
    city.put("country", "USA");
    db.collection("users").document(auth.getCurrentUser().getUid()).set(city);
}

哪些工作正常，然后我尝试添加一个简单的类作为要上传的对象。如下：

protected final void uploadUser()
{
    class Stupid {
        public String name;
        public String email;

        public Stupid()
        {
        }

        public Stupid(String name, String email)
        {
            this.name = name;
            this.email = email;
        }

        public String getName()
        {
            return name;
        }

        public void setName(String name)
        {
            this.name = name;
        }

        public String getEmail()
        {
            return email;
        }

        public void setEmail(String email)
        {
            this.email = email;
        }
    }
    Stupid stupid = new Stupid("Name", "Email");
    db.collection("users").document(auth.getCurrentUser().getUid()).set(stupid);
}

再次，我给setWallpaper带来了同样的错误。我还尝试了使用整数而不是字符串的Stupid类的另一个变体。也一样愚蠢的简单的POJO类。这件事到底有什么问题？我之前用所有的时间来使用类和对象与火力地堡数据库。在这种情况下我想念什么？

好吧，所以我做了两件事，不确定是哪一个修复了它（也许都是吗？！）

以前，我是在检查Google Play服务的可用性。因此，为此，我加入了com.google.android.gms:play-services-base:16.1.0。导致我收到错误Error: Cannot fit requested classes in a single dex file. Try supplying a main-dex list. # methods: 72477 > 65536。我的解决方案是添加multiDexEnable 'true'。我现在要做的是改为遵循this answer。因此，我删除了所有多dex内容，并改用com.google.android.gms:play-services-gcm:16.0.0。

我做的第二件事是禁用即时运行。

现在，我拥有的相同代码的工作原理就像一个超级按钮，可以在Firestore中读取/写入。

我对发生的事情没有任何解释。但是问题现在消失了。
