我在我的项目中使用 FirebaseFirestore。当我处于 Debug模式时,minifyEnabled FALSE,应用程序运行得很好,但是当我构建一个签名的 .apk 时,minifyEnabled TRUE,它并没有像我预期的那样工作。即它不会从 firebase Firestore 加载数据。

我应该写什么 KEEP 语句来从缩小中排除 FIREBASE FIRESTORE 和 Glide 类?

dependencies {
implementation 'com.android.support:appcompat-v7:28.0.0'

implementation 'com.google.firebase:firebase-core:16.0.9'
implementation 'com.google.firebase:firebase-firestore:19.0.0'
implementation 'com.google.firebase:firebase-ads:17.2.0'

我的混淆配置

buildTypes {
release {
minifyEnabled true
shrinkResources false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),


'proguard-rules.pro'
}
}

proguard-android-optimize.txt-3.4.1

最佳答案

解决方案:ProGuard 几乎重命名了每个类。它重命名了我的模型类 (pojo),我用它来封装 Firestore 的数据,而 firestore 只识别这个名称,在我的例子中是“上传”。

但是当混淆器重命名它时,它将“上传”类命名为“j”而且,Firestore SDK 无法识别“j”。

这就是问题所在。

我补充说“@Keep”注解加上“Upload”类,我的问题就解决了。

@Keep
public class Upload{
.....
.....
}
