Question

哦，我多么讨厌这个错误。

我得到了可怕的dexDebug错误，但这次我不知道如何修复它。

确切的错误是：

我只有两个依赖项和一个相当干净的app.gradle，如下所示：

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.appzylabs.pratik.dailydeals"
        minSdkVersion 8
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"

    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile 'com.android.support:support-v4:23.0.0'
}

以下是我试图解决的问题，但无济于事： 1）我包括了JSoup的jar，但我删除了它。没有帮助。 2）我添加了multidex支持（multiDexEnabled true）和android：name =＆＃34; android.support.multidex.MultiDexApplication＆＃34;在我的AndroidManifest.xml中。纳达。 3）我做了一个干净/构建，并清除缓存并重新启动android studio。什么都没有。

请注意，仅当我尝试运行asyncTask时才会发生这种情况。如果我注释掉那条线就会像魅力一样编译：

new MyLoadWebView().execute("");

问题是什么？有人可以帮忙吗？

好的，基于Android dex issue: nested class + final boolean : com.android.dex.util.ExceptionWithContext，我认为我为异步任务创建的内部类有问题。所以我所做的是将AsyncTask的类声明从私有更改为public：

private class MyLoadWebView extends AsyncTask<String, Void, Void> { ..

到

public class MyInnerLoadWebView extends AsyncTask<String, Void, Void> { ..

它有效!!!!

我仍然不知道为什么会这样，但似乎是一个严重的错误。有什么意见吗？
