问题描述
这个错误真的真的很奇怪，我不知道如何重现它以及如何修复它，因为我进行了大量搜索但没有任何用处.
this error is really really really strange and I don't know how to reproduce it and how to fix it because I made a lot of searches but nothing was useful.
这是堆栈跟踪:

请不要问我清单中是否有正确的 INTERNET 权限，因为此应用已上市 2 年:P
Please don't bother asking me if I have the correct INTERNET permission in my manifest because this app is in market since 2 years :P
我还注意到(来自 Crittercism)所有错误都来自 Android 4.1.x 版本 (JB).我不知道设备是否已 root 或什么(我暂时看不到此信息)
I've also noticed that (from Crittercism) all bugs are coming from Android 4.1.x version (JB). I don't know if device are rooted or what (I can't see this information for the moment)
推荐答案
注意:我在 2013 年 6 月写了这个答案，所以现在有点过时了.自第 6 版(Marshmallow，2015 年末发布)以来，Android 平台发生了许多变化，使整个问题或多或少都过时了.不过我相信这篇文章作为一般问题分析方法的例子仍然值得一读.
您收到的异常 (SecurityException: Permission denied (missing INTERNET permission?))，清楚地表明您不被允许进行网络连接.这是相当不争的事实.但这怎么会发生呢?通常是由于缺少 <uses-permission android:name="android.permission.INTERNET";/> 在您的 AndroidManifest.xml 文件中输入，或者由于 Internet 权限是在安装时而非运行时授予的，长期存在的 Android 框架中遗漏的错误导致您的应用程序已成功安装，但未授予预期权限.
Exception you are getting (SecurityException: Permission denied (missing INTERNET permission?)), clearly indicates that you are not allowed to do networking. That's pretty indisputable fact. But how can this happen? Usually it's either due to missing <uses-permission android:name="android.permission.INTERNET" /> entry in your AndroidManifest.xml file or, as internet permission is granted at installation not at run time, by long standing, missed bug in Android framework that causes your app to be successfully installed, but without expected permission grant.
我的 Manifest 是正确的，怎么会发生这种情况?
理论上，Manifest 中 uses-permission 的存在完美地满足了要求，从开发人员的角度来看，这就是能够进行网络连接所需要做的一切.此外，由于在安装过程中向用户显示了权限，因此您的应用程序最终安装在用户的设备上这一事实意味着他/她授予了您的要求(否则安装将被取消)，因此假设如果您的代码被执行，那么所有请求的权限都是授予是有效的.并且一旦被授予，用户除了完全卸载应用程序之外，无法撤销该权限，因为标准 Android 框架(来自 AOSP)目前不提供此类功能.
Theoretically, presence of uses-permission in Manifest perfectly fulfills the requirement and from developer standpoint is all that's needed to be done to be able to do networking. Moreover, since permissions are shown to the user during installation, the fact your app ended installed on user's device means s/he granted what you asked for (otherwise installation is cancelled), so assumption that if your code is executed then all requested permissions are granted is valid. And once granted, user cannot revoke the permission other way than uninstalling the app completely as standard Android framework (from AOSP) offers no such feature at the moment.
但是如果您也不介意您的应用在 rooted 上运行，事情会变得更加棘手设备也是.您的用户可以在 Google Play 中安装一些工具来控制授予已安装应用的权限在运行时 - 例如:权限被拒绝等.这也可以通过 CyanogenMod、供应商品牌(即 LG 的)或 其他自定义ROM，具有各种类型的";隐私经理"或类似工具.
But things are getting more tricky if you also do not mind your app running on rooted devices too. There're tools available in Google Play your users can install to control permission granted to installed apps at run-time - for example: Permissions Denied and others. This can also be done with CyanogenMod, vendor brand (i.e. LG's) or other custom ROM, featuring various type of "privacy managers" or similar tools.
因此，如果应用程序以任何一种方式被阻止，它基本上是被用户故意阻止的，如果是这样，在这种情况下，这确实是更多的用户问题(或者他/他不了解某些选项/工具的真正作用以及将是什么后果)而不是你的，因为标准 SDK(大多数应用程序都是用该 SDK 编写的)根本不会那样做.因此，我强烈怀疑此问题会出现在标准"、无根设备(或三星、HTC、索尼等供应商)ROM 上.
So if app is blocked either way, it's basically blocked intentionally by the user and if so, it is really more user problem in this case (or s/he do not understand what certain options/tools really do and what would be the consequences) than yours, because standard SDK (and most apps are written with that SDK in mind) simply does not behave that way. So I strongly doubt this problem occurs on "standard", non-rooted device with stock (or vendor like Samsung, HTC, Sony etc) ROM.
我不想崩溃...
正确实施权限管理和/组织阻止必须处理这样一个事实，即大多数应用程序可能还没有准备好应对某些功能的访问权限既被授予又无法同时访问的情况，因为这在应用程序中是一种矛盾使用清单在安装时请求访问.正确完成访问控制应该使所有事情都像以前一样工作，并且仍然在功能的预期行为范围内使用技术限制可用性.例如，当授予某些许可(即 GPS、Internet 访问)时，可以从应用程序/用户的角度(即您可以打开 GPS 或尝试连接)使此类功能可用，更改后的实现无法提供真实数据 -即 GPS 始终无法返回坐标，例如当您在室内或没有卫星修复"时.可以像以前一样授予 Internet 访问权限，但由于没有数据覆盖或路由，因此无法成功连接.在正常使用中也应该预料到这种情况，因此它应该已经由应用程序处理.由于这种情况可能发生在正常的日常使用中，因此在这种情况下发生的任何崩溃很可能与应用程序错误有关.
Properly implemented permission management and/org blocking must deal with the fact that most apps may not be ready for the situation where access to certain features is both granted and not accessible at the same time, as this is kind of contradiction where app uses manifest to request access at install time. Access control done right should must make all things work as before, and still limit usability using techniques in scope of expected behavior of the feature. For example, when certain permission is granted (i.e. GPS, Internet access) such feature can be made available from the app/user perspective (i.e. you can turn GPS on. or try to connect), the altered implementation can provide no real data - i.e. GPS can always return no coordinates, like when you are indoor or have no satellite "fix". Internet access can be granted as before, but you can make no successful connection as there's no data coverage or routing. Such scenarios should be expected in normal usage as well, therefore it should be handled by the apps already. As this simply can happen during normal every day usage, any crash in such situation should be most likely be related to application bugs.
我们缺乏关于发生此问题的环境的太多信息，无法通过猜测来诊断问题，但作为一种解决方案，您可以考虑使用 setDefaultUncaughtExceptionHandler() 将来捕获此类意外异常，即简单地向用户显示详细信息是什么您的应用程序需要的权限，而不仅仅是崩溃.请注意，使用它很可能会与 Crittercism、ACRA 等工具发生冲突，因此使用这些工具时要小心.
We lack too much information about the environment on which this problem occurs to diagnose problem w/o guessing, but as kind of solution, you may consider using setDefaultUncaughtExceptionHandler() to catch such unexpected exceptions in future and i.e. simply show user detailed information what permission your app needs instead of just crashing. Please note that using this will most likely conflict with tools like Crittercism, ACRA and others, so be careful if you use any of these.
注意事项
请注意，android.permission.INTERNET 不是您可能需要在清单中声明的唯一与网络相关的权限，以尝试成功进行网络连接.授予 INTERNET 权限只是允许应用程序打开网络套接字(这基本上是进行任何网络数据传输的基本要求).但是，如果您的网络堆栈/库也想获取有关网络的信息，那么您的清单中还需要 android.permission.ACCESS_NETWORK_STATE(即 HttpUrlConnection 客户端(参见教程).
Please be aware that android.permission.INTERNET is not the only networking related permission you may need to declare in manifest in attempt to successfully do networking. Having INTERNET permission granted simply allows applications to open network sockets (which is basically fundamental requirement to do any network data transfer). But in case your network stack/library would like to get information about networks as well, then you will also need android.permission.ACCESS_NETWORK_STATE in your Manifest (which is i.e. required by HttpUrlConnection client (see tutorial).
附录 (2015-07-16)
请注意，Android 6(又名 Marshmallow)引入了全新的权限管理机制，称为运行时权限.它让用户可以更好地控制授予的权限(也允许选择性授予)，或者让用户撤销已授予的权限，而无需删除应用程序:
Please note that Android 6 (aka Marshmallow) introduced completely new permission management mechanism called Runtime Permissions. It gives user more control on what permission are granted (also allows selective grant) or lets one revoke already granted permissions w/o need to app removal:
这 [...] 引入了一种新的权限模型，用户现在可以在其中在运行时直接管理应用程序权限.该模型为用户提供改进了对权限的可见性和控制，同时简化了应用程序开发人员的安装和自动更新过程.用户可以单独授予或撤销已安装应用的权限.
但是，更改不会影响 INTERNET 或 ACCESS_NETWORK_STATE 权限，它们被视为正常"权限.用户无需明确授予这些权限.
However, the changes do not affect INTERNET or ACCESS_NETWORK_STATE permissions, which are considered "Normal" permissions. The user does not need to explicitly grant these permission.
请参阅行为更改说明页面了解详情，并确保您的应用能够在较新的系统上也能正常运行.当您的项目将 targetSdk 设置为至少 23 时尤为重要，因为您必须支持新的权限模型(详细文档).如果您还没有准备好，请确保将 targetSdk 保持为最多 22，因为这可以确保即使是新的 Android 在您的应用安装时也会使用旧的权限系统.
See behavior changes description page for details and make sure your app will behave correctly on newer systems too. It's is especially important when your project set targetSdk to at least 23 as then you must support new permissions model (detailed documentation). If you are not ready, ensure you keep targetSdk to at most 22 as this ensures even new Android will use old permission system when your app is installed.
