我的安卓应用在调试模式下运行正常，但在发布模式下崩溃。当我尝试使用 Firebase 登录时，就会出现问题 Auth.App 如果我在发布版本中设置可调试 ： true，则工作正常。Log cat 提供与原子字段更新相关的错误。是因为 proguard 正在删除某些类吗？我在下面提供了代码和日志猫：
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();
}
错误：

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
}
根据我的观察，我认为模型类(当前用户(的名称声明在使用 proguard 规则后发生了变化，因此添加一个语句以从 proguard 中排除 Currentuser.class 将解决问题。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 类位于路径 java/in/permabull/permabull/CurrentUser 中，则根据此更改。干杯:)
我必须禁用 R8 才能解决此问题，谷歌已经打开了一个问题 https://r8-review.googlesource.com/c/r8/+/26161
