java.lang.ClassNotFoundException:在路径上找不到类:DexPathList，更新 sdk 后 [英] java.lang.ClassNotFoundException: Didn't find class on path: DexPathList , After updating sdk

问题描述

大家好，我的应用程序一直运行良好，直到昨天，我昨天更新了我的 SDK，它首先开始报错，然后报错

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 ....

我搜索并通过更改 build.gradle 中的以下行来解决它

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

compileSdkVersion 25
buildToolsVersion '25.0.2'

现在错误消失了，它在更高的 android 版本 7.1.1 中运行完全正常但是当我在 低版本 的 android 中运行时，它会给出以下 error

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

我已经尝试过以下的事情

1.清理项目

2.使缓存失效/重启

3.设备上应用的删除

已经看过这些问题问题1，问题2没有任何效果.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?

如果你需要任何东西，我会更新它

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

像下面这样写一个类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中将这个类写入Application标签

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">
