如何解決Android App在發行版本類型時崩潰但在Debug Build類型中起作用

Question

使用發布類型進行構建時，Android應用程序在手機中崩潰，但是當使用調試構建類型進行構建或在發布模式下啟用調試時，Android應用程序可以正常運行。

Logcat錯誤顯示由於抽象類之一而導致的驗證錯誤

該應用程序中沒有proguard文件。 我試圖通過在build.gradle中添加'useProguard false'來解決問題，但這無濟於事

apply plugin: 'com.android.application'

android {
    useLibrary 'org.apache.http.legacy'
    compileSdkVersion 28

    defaultConfig {
        applicationId "com.newgen.mcap.srei"
        minSdkVersion 21
        targetSdkVersion 28
    }

    buildTypes {
        release {
            minifyEnabled false

        }
    }
    lintOptions {
        checkReleaseBuilds false
        disable "ResourceType"
    }

}

dependencies {
    compile 'com.android.support:support-v4:23.4.0'
    compile files('libs/com.antlersoft.android.db_0.1.6.jar')
    compile files('libs/commons-lang3-3.1.jar')
    compile files('libs/dmsapi.jar')
    compile files('libs/ImgAndro.jar')
    compile files('libs/NGSecurity.jar')
}

Logcat錯誤在這里：

我的問題不是Link的重復，因為崩潰是由於構建類型引起的，而不是由於Android API級別引起的。 我已經嘗試通過刪除生成和發布文件夾之前的生成和發布文件夾來嘗試接受的答案。

Answer 1

它與調試/發布版本無關。 您應該在

com.newgen.mcap.client.util.NGCaptureSingleton.getDefaultCustomHelperForName
(NGCaptureSingleton.java:109)

Answer 2

步驟1：打開Android Studio設置，然后轉到Build，Execution，Deployment-> Gradle Copy Gradle Service目錄路徑在我的情況下是C：/Users/bhanu.sharma/.gradle

步驟2：打開文件資源管理器並粘貼Gradle服務目錄路徑如果不存在，請在此處添加文件gradle.properties。

第3步：打開Android Studio並將項目類型更改為Android，您將在此處看到gradle.properties文件

步驟4：在gradle.properties文件中添加android.enableD8 = false行。

步驟5：清理並構建簽名的apk。
