我的應用程序在調試時工作正常（在虛擬和真實設備上），但在發布構建后它不能在任何地方工作（因為 Retrofit 拋出錯誤）。 我嘗試了所有存在的方法來修復它，但任何一個都不起作用。

1. 我的進口很好。
2. 我添加了proguard規則：

-keepattributes *Annotation*
-keep class retrofit.* { *; }
-keepclasseswithmembers class * {
@retrofit.http.* <methods>; }
-keepattributes Signature

3. 我的依賴：

dependencies {
    implementation 'org.jetbrains:annotations:19.0.0'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    compileOnly 'org.projectlombok:lombok:1.18.18'
    annotationProcessor 'org.projectlombok:lombok:1.18.18'
    testCompileOnly 'org.projectlombok:lombok:1.18.18'
    testAnnotationProcessor 'org.projectlombok:lombok:1.18.18'
    implementation 'com.fasterxml.jackson.core:jackson-core:2.12.1'
    implementation 'com.fasterxml.jackson.core:jackson-annotations:2.12.1'
    implementation 'com.squareup.retrofit2:retrofit:2.9.0'
    implementation 'com.squareup.retrofit2:converter-jackson:2.9.0'
    implementation 'androidx.core:core:1.5.0-beta01'
    implementation 'com.squareup.retrofit2:adapter-rxjava:2.9.0'
    implementation 'com.squareup.okhttp3:logging-interceptor:4.3.1'
    implementation 'com.squareup.okhttp3:okhttp:4.3.1'

    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'com.google.android.material:material:1.3.0'
    implementation 'androidx.annotation:annotation:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
    implementation 'androidx.lifecycle:lifecycle-livedata-ktx:2.3.0'
    implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.3.0'
    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}

4. 我的構建類型：

release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            debuggable false
            jniDebuggable false
            renderscriptDebuggable false
            renderscriptOptimLevel 3
            applicationIdSuffix '.aminoapps'
            multiDexEnabled true
        }

Answer 1

很奇怪，你可以試試這個proguard規則看看它是否有效

# Retrofit does reflection on generic parameters. InnerClasses is required to use Signature and
# EnclosingMethod is required to use InnerClasses.
-keepattributes Signature, InnerClasses, EnclosingMethod

# Retain service method parameters when optimizing.
-keepclassmembers,allowshrinking,allowobfuscation interface * {
    @retrofit2.http.* <methods>;
}

# Ignore annotation used for build tooling.
-dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement

# Ignore JSR 305 annotations for embedding nullability information.
-dontwarn javax.annotation.**

# Top-level functions that can only be used by Kotlin.
-dontwarn retrofit2.KotlinExtensions
-dontwarn retrofit2.KotlinExtensions$*
