java.lang.RuntimeException:无法实例化应用程序:ClassNotFoundException(仅在X86架构设备上)

Question

这似乎是Stack Overflow中提出的最高问题之一,但即使在尝试了10多个问题的20多个解决方案并引用Android Docs之后,我的问题仍未解决.

问题
1.应用程序在非x86设备上运行良好,如摩托罗拉,三星S6,三星S7
2.应用程序在x86架构设备上抛出该错误.

我到目前为止尝试过的内容
1.我在Manifest,包等中交叉检查包名称
.2.将完整和部分包名称提供给android:name清单中的属性.
3.尝试Application从utils包中移动类到主包.

背景
1.安装Android Studio时 - sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 lib32bz2-1.0除了之外一切正常lib32bz2-1.0,但到目前为止还没有问题.(之前没试过在x86设备上安装应用程序) 2.CompileSDKVersion -
25
3. BuildToolsVersion - 25.0.0
4. Gradle版本 - 2.2.2

工作环境
1. Ubuntu 16.04
2.更新了JAVA 8
3. Android Studio 2.2.2

编辑: 我认为可能导致问题的gradle(app)的一部分

packagingOptions {
    exclude 'META-INF/NOTICE' // will not include NOTICE file
    exclude 'META-INF/LICENSE' // will not include LICENSE file
    exclude 'META-INF/notice'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license'
    exclude 'META-INF/license.txt'
}
sourceSets {
    main {
        java.srcDirs = ['src/main/java']
    }
    robolectric {
        java.srcDir file('src/test/java/')
    }
}

PS交叉检查了Manifest几次,似乎没有问题.在任何Android文档中都找不到任何可能的异常原因.

更新:在参考此答案后启用即时运行不会导致问题.但是通过安装应用程序debug.apk会产生同样的问题.

将jack-compiler和MultiDex一起使用时,这是一个已知问题.这导致NoClassDefFoundErrorPre-Lollipop设备,也可能在Pre-Marshmallow上.解决方案是禁用jack-compiler,然后使用RetroLambda.

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'me.tatarka:gradle-retrolambda:3.6.0'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'me.tatarka.retrolambda'

repositories {
   mavenCentral()
}

android {
    compileSdkVersion 25
    buildToolsVersion '25.0.2'
    defaultConfig {
        applicationId "your.application.id"
        minSdkVersion 16
        targetSdkVersion 25
        multiDexEnabled true

        jackOptions {
            enabled false
        }
        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_8
            targetCompatibility JavaVersion.VERSION_1_8
        }
    }

}

不要忘记向Thomas Sunderland提出他的回答,因为这就是我找到这个解决方案的方式.

Answer 2

您的应用程序类应该extends MultiDexApplication代替extends Application.

希望这可以帮助。

Answer 3

此错误的原因之一是由于 MultiDexApplication 。我在其他一些库中遇到过此类问题

要解决这个问题，您需要处理多个 Dex 文件。在应用程序的帮助下build.gradle&Application class

build.gradle以下是文件中所需的更改

dexOptions {
        incremental true
        // here heap size give 4g(for ubuntu you can try with 2g) i got this thing from //https://groups.google.com/forum/#!topic/adt-dev/P_TLBTyFWVY

        javaMaxHeapSize "4g"
    }


dependencies {
     compile 'com.android.support:multidex:1.0.1'
    //    your dependencies which you are using.

}

全部的build.gradle

android {
    signingConfigs {
        /*
        releasebuild {
            keyAlias 'hellotest'
            keyPassword 'hellotest'
            storeFile file('path to keystore')
            storePassword 'hellotest'
        }
        */
    }
    compileSdkVersion 'Google Inc.:Google APIs:22'
    buildToolsVersion '23.0.0'
    /* if you got error regarding duplicate file of  META-INF/LICENSE.txt from jar file
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
    }
    */
    dexOptions {
        jumboMode = true
        incremental true
        // here heap size give 4g i got this thing from https://groups.google.com/forum/#!topic/adt-dev/P_TLBTyFWVY

        javaMaxHeapSize "4g"
    }
    defaultConfig {
        multiDexEnabled true
        applicationId "com.myapp.packagenme"
        minSdkVersion 17
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.releasebuild
        }
        debug {
            signingConfig signingConfigs.releasebuild
        }
    }
}

dependencies {
     compile 'com.android.support:multidex:1.0.1'
    //    your dependencies which you are using.

}

如果您的应用程序使用扩展的Application类，您可以重写attachBaseContext()方法并调用MultiDex.install(this)来启用multidex。使用应扩展的 Applicaiton 类 安装 Multipledex 文件上下文

public class MyAppClass extends MultiDexApplication{
@Override
    protected void attachBaseContext(Context newBase) {
        MultiDex.install(newBase);
        super.attachBaseContext(newBase);
    }
}

javaMaxHeapSize "4g" 尝试使用2gif 以防 ubuntu 系统出现任何错误。

如果有什么事情请告诉我
