java.lang.ClassNotFoundException:在路径上找不到类:DexPathList,更新sdk后

Question

大家好我的应用程序一切正常,直到昨天,我昨天更新了我的SDK,它开始给出错误,它首先给出了一个错误

没有找到值v24的资源....

像这样的一些东西我搜索并通过更改build.gradle中的以下行来解决它

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 但是当我在较低版本的android中运行它给出以下错误

我已经尝试过以下事情

1.清洁项目

2.无效缓存/重启

3.删除设备上的应用程序

已经看过这些问题 问题1,问题2没什么用.我该如何解决这个问题？

如果你需要任何东西我会更新它的问题

我的build.gradle文件

 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

    }

Answer 1

写一个EnableMultiDex像下面这样的类

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();

    }
}

并将AndroidManifest.xml此类写入 Application 标记内

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