java.lang.ClassNotFoundException: 未在路径 DexPathList 上找到 class ...

Question

我正在制作一个 android 项目游戏，我最近向该项目添加了一些库，但由于我这样做，我得到了同样的错误：

dex2oat : Failed to create oat file: /data/dalvik-cache/arm/data@app@***.*******.*************-2@base.apk@classes.dex: Permission denied
    java.lang.ClassNotFoundException: Didn't find class "***.*******.*************.MainActivity" on path: DexPathList[[zip file "/data/app/***.*******.*************-1/base.apk"],nativeLibraryDirectories=[/data/app/***.*******.*************-1/lib/arm, /vendor/lib, /system/lib]]

我相信我应该说所有项目/库项目都使用相同的目标 "android-23"。我检查了 Whosebug 和其他网站上的所有答案，但找不到解决我问题的任何答案。感谢您的帮助！

该项目是在 Netbeans IDE 框架上编写的，而不是在 android studio 上编写的，并且该项目未使用 gradle。这是 AndroidManifest.xml 文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="***.*******.*************"
          android:versionCode="7"
          android:versionName="1.5">
    <application android:label="@string/app_name" android:icon="@drawable/icon"
    >
        <meta-data android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />
        <activity 
            android:screenOrientation="landscape"
            android:name="MainActivity"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

经过一些挖掘后，似乎 dex2oat 尝试创建 oat 文件时出现问题：

dex2oat : Failed to create oat file: /data/dalvik-cache/arm/data@app@***.*******.*************-2@base.apk@classes.dex: Permission denied

我现在不知道该怎么办。引用的库：Google Play 服务和 Android 支持 v13。如果我删除库，项目工作正常...那么问题是什么？

Answer 1

好吧，找了半天发现问题出在android的sdk管理器上——我下载了所有的构建工具，而我只需要下载一个。所以我删除了所有不必要的包，项目现在运行良好。感谢那些试图提供帮助的人！

Answer 2

我的此类问题已通过以下方式解决：- 1) 清理 2) 构建 --> 构建 Apk。这个 Apk 之前运行良好，我只是从 app->build->output->apk 处理。

java.lang.ClassNotFoundException: 未在路径 DexPathList 上找到 class ...

java.lang.ClassNotFoundException: Didn't find class ... on path: DexPathList

java

android

netbeans

dex2oat
