java.lang.ClassNotFoundException:在更新sdk之后，未在路径:DexPathList上找到类 [英] java.lang.ClassNotFoundException: Didn't find class on path: DexPathList , After updating sdk

问题描述

大家好，我的应用程序直到昨天都运行良好，我昨天更新了我的SDK，首先开始给出错误，然后给出了错误

Hello guys My application was all working fine till yesterday, i updated my SDK yesterday and it started giving error first it gave an error

在值v24处找不到资源....

No resource found at values v24 ....

我通过更改build.gradle中的以下行来搜索并解决了此问题

some thing like this i searched and solved it by changing following lines in build.gradle

compileSdkVersion 25
buildToolsVersion '25.0.2'

现在该错误已消失，并且在更高版本的android版本 7.1.1 中运行完全正常 但是当我在较低版本的android中运行 时，出现以下错误

now that error is gone and It is running completely fine in higher android version 7.1.1 but when i run in lower version of android it is giving following error

我已已尝试以下操作

1.清理项目

2.无效缓存/重新启动

2.invalidate cache /restart

3.删除设备上的应用

3.The deletion of app on device

已经查看了以下问题问题1 ，问题2 无效.我该如何解决这个问题?

already looked at these questions Question 1 , Question 2 nothing worked . How can i fix this issue?

如果您需要任何东西，我会进行更新

if you need any thing i will update it in question

我的build.gradle文件

my build.gradle file

 apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion '25.0.2'

    defaultConfig {
        applicationId "com.wowio.ebookreader"
        minSdkVersion 14
        targetSdkVersion 23
        multiDexEnabled true

    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
    dexOptions {
        javaMaxHeapSize "4g"
    }
}

dependencies {

    compile 'com.android.support:appcompat-v7:+'
    compile 'com.google.android.gms:play-services:+'
    compile 'com.android.support:multidex:1.0.1'
     // the are many more dependencies i removed to decrease size

    }

推荐答案

像下面这样编写类EnableMultiDex

public class EnableMultiDex extends MultiDexApplication {
    private static EnableMultiDex enableMultiDex;
    public static Context context;

    public EnableMultiDex(){
        enableMultiDex=this;
    }

    public static EnableMultiDex getEnableMultiDexApp() {
        return enableMultiDex;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        context = getApplicationContext();

    }
}

并在AndroidManifest.xml中在Application标签内编写此类.

and in AndroidManifest.xml write this class inside Application tag

 <application
    android:name="YourPakageName.EnableMultiDex"
    android:hardwareAccelerated="true"
    android:icon="@drawable/launch_logo"
    android:label="@string/app_name"
    android:largeHeap="true"
    tools:node="replace">
