如何解决Android App在发行版本类型时崩溃但在Debug Build类型中起作用

Question

使用发布类型进行构建时，Android应用程序在手机中崩溃，但是当使用调试构建类型进行构建或在发布模式下启用调试时，Android应用程序可以正常运行。

Logcat错误显示由于抽象类之一而导致的验证错误

该应用程序中没有proguard文件。 我试图通过在build.gradle中添加'useProguard false'来解决问题，但这无济于事

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错误在这里：

我的问题不是Link的重复，因为崩溃是由于构建类型引起的，而不是由于Android API级别引起的。 我已经尝试通过删除生成和发布文件夹之前的生成和发布文件夹来尝试接受的答案。

Answer 1

它与调试/发布版本无关。 您应该在

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

Answer 2

步骤1：打开Android Studio设置，然后转到Build，Execution，Deployment-> Gradle Copy Gradle Service目录路径在我的情况下是C：/Users/bhanu.sharma/.gradle

步骤2：打开文件资源管理器并粘贴Gradle服务目录路径如果不存在，请在此处添加文件gradle.properties。

第3步：打开Android Studio并将项目类型更改为Android，您将在此处看到gradle.properties文件

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

步骤5：清理并构建签名的apk。
