标签： java android netbeans dex2oat

我正在制作一个Android项目游戏，我最近在这个项目中添加了一些库，因为我做了同样的错误：

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

我相信我应该说所有的项目/图书馆项目都使用相同的目标“android-23”。我已经检查了StackOverflow和其他网站上的所有答案，但无法找到解决我问题的任何答案。 谢谢你的帮助！

修改

该项目是在Netbeans IDE框架上编写的，而不是在android studio上，项目不是使用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>

编辑＃2

经过一些挖掘后，似乎dex2oat尝试创建燕麦文件时出现问题：

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

我不知道现在该做什么。 参考图书馆：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？

2 个答案:

答案 0 :(得分：3)

我的这个问题通过以下方式解决： - 1）清洁2）构建 - ＆gt;建立Apk。而这个Apk之前工作得很好我只是应用app-＆gt; build-＆gt; output-＆gt; apk。

答案 1 :(得分：1)

好吧，所以经过长时间的搜索后发现问题出在Android的sdk经理身上 - 我下载所有的构建工具时只需要下载一个。 所以我删除了所有不必要的包，项目现在正常工作。 感谢那些试图帮助的人！
