未在路径上找到 class "com.jambod.user.model.ProcessModel"：发布 apk 时出现 DexPathList 错误

Question

我编写了一个应用程序，并在 it.For 上使用了 dagger-android 和导航组件，减少了 apk 的大小我启用了 minifyEnabled 和 shrinkResources。但是当我生成 apk 并打开应用程序时，应用程序是 crashed.I 跟踪 logcat 并且错误是 Caused by java.lang.ClassNotFoundException Didn't find class "com.jambod.user.model.ProcessModel" on path: DexPathList。这是 ProcessModel:

的代码

    data class ProcessModel(
    var id: String,
    var state: String ,
    var originLat: Double,
    var originLon: Double,
    var originAddress: String,
    var city: String ,
    var client: User ,
    var broker: Broker,
    var handover: HandOver ,
    var startTime: Long ,
    var endTime: Long ,
    var clientScore: Int,
    var role:String,
    var isFirstFinishedProcess:Boolean

) : Serializable {
}

这是我的申请 class:

    class MyApplication : DaggerApplication() {

    val TAG="MyApplication"
    @Inject
    lateinit var mapboxMap: CedarMaps

    override fun applicationInjector(): AndroidInjector<out DaggerApplication> {

        Log.e(TAG,"applicationInjector")
        return DaggerAppComponent.builder().application(this).build()

    }

    override fun onCreate() {
        super.onCreate()
        Log.e(TAG,"onCreate")
        setMapview()
    }

    override fun attachBaseContext(base: Context) {
        super.attachBaseContext(base)
        Log.e(TAG,"attachBaseContext")
        MultiDex.install(this)
    }

    private fun setMapview() {
        mapboxMap.setClientID("jambod-3804728105994932624")
                .setClientSecret("b37qDGphbWJvZLqxi8hCuQhrjCXtqKs9V536SyiAAHQP01FzTg3G0iat")
                .setContext(this)
    }

}

而logcat中的这部分代码移动导航文件有错误：

  <fragment android:id="@+id/detailProcessFragment" android:name="com.jambod.user.ui.DetailProcessFragment"
          android:label="fragment_detail_process" tools:layout="@layout/fragment_detail_process">
    <argument android:name="KEY_PROCESS"
        app:argType="com.jambod.user.model.ProcessModel"
        app:nullable="true"
        android:defaultValue="@null"/>
</fragment>

根据document我创建了一个multidex-config.txt文件并添加到build.gradle但是没有问题solve.This是build.gradle文件：

 defaultConfig {
    applicationId "com.jambod.user"
    minSdkVersion 16
    targetSdkVersion 29
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}
buildTypes {
    release {
        multiDexKeepFile file('multidex-config.txt')
        minifyEnabled true
        shrinkResources true
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}

Answer 1

因为您正在使用 "minifyEnabled true" 和混淆器。 "minifyEnabled true" 有时会删除您在应用中使用的模型 classes。在 Gradle 脚本 -> proguard-rules.pro 文件中添加以下行。下面一行会将 class 及其成员保留到您的最终 APK 中。

-keepclasseswithmembernames  class  com.jambod.user.model.ProcessModel.** { *; }
