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应用程序可以正常工作。

Logcat错误显示由于抽象类之一而导致的验证错误

应用程序中没有proguard文件。我尝试通过添加 build.gradle中的'useProguard false'，但无济于事

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')
}

此处的Logcat错误：

我的问题不是Link的重复项因为崩溃是由于构建类型而不是由于android api级别。而且我在构建apk之前先删除了build和release文件夹，从而尝试了可接受的答案。

Answer 1

它与调试/发布版本无关。您应该在

中处理异常

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“构建，执行，部署-> Gradle” 复制Gradle服务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服务目录路径如果文件gradle.properties不存在，请在此处添加

第3步：打开Android Studio并将项目类型更改为Android，您将看到 gradle.properties文件在这里

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

第5步：清理并构建已签名的APK。
