android - Firebase Android：创建原子字段更新程序失败，java.lang.IllegalArgumentException：必须是整数类型

问题描述

我的 Android 应用在调试模式下运行良好，但在发布模式下崩溃。当我尝试使用 Firebase Auth.App 登录时会出现问题，如果我在发布版本中设置 debuggable : true 可以正常工作。日志 cat 提供 Atomic 字段更新相关的错误。是因为 proguard 正在删除一些课程吗？我在下面提供了代码和 Logcat：

if (task.getException() instanceof FirebaseAuthUserCollisionException) {
    Toast.makeText(SignUpActivity.this, "You are already registered", Toast.LENGTH_SHORT).show();
    mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {
            progressBar.setVisibility(View.GONE);
            if (task.isSuccessful()) {
                FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
                String uid = user.getUid();
                sharedPref = getApplicationContext().getSharedPreferences(uid, Context.MODE_PRIVATE);
                sharedPref.edit().clear().commit();

                DocumentReference docRef = db.collection("PB_USERS").document(uid);
                docRef.get().addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>() {
                    @Override
                    public void onComplete(@NonNull Task<DocumentSnapshot> task) {
                        if (task.isSuccessful()) {
                            SharedPreferences.Editor editor = sharedPref.edit();
                            DocumentSnapshot document = task.getResult();
                            if (document.exists()) {
                                CurrentUser currentUser = document.toObject(CurrentUser.class);
                                ArrayList<String> purchases = currentUser.getPurchases();
                                for (String purchasedTrade : purchases) {
                                    editor.putBoolean(purchasedTrade, false);
                                }
                                editor.apply();


                                Intent intent = new Intent(SignUpActivity.this, MainActivity.class);
                                    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                                    startActivity(intent);
                                    finish();

                            }

我是 Android 和 Java 的初学者。这是应用程序 build.gradle 部分：

 compileSdkVersion 27
    defaultConfig {
        applicationId "in.permabull.permabull"
        minSdkVersion 19
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.config
        }

解决方案

根据我的观察，我认为模型类（CurrentUser）的名称声明在使用 proguard 规则后发生了变化，因此添加一条语句以从 proguard 中排除 Currentuser.class 将解决该问题。将以下语句添加到项目文件夹中的 progurad-rules.pro 文件中

-keep class in.permabull.permabull.CurrentUser { *; }

注意：如果 CurrentUser 类驻留在路径 java/in/permabull/permabull/CurrentUser 中，则根据其他更改。干杯:)
