我正在使用地震报告应用程序，我已经为INTERNET和ACCESS_NETWORK_STATE的清单文件添加了权限。我进入了模拟器的设置和开发人员的设置，并确保所有网络设置都已正确设置。我在这里研究过这个问题＆amp;尝试了那些对我不起作用的建议。由于防火墙，我还看到了其他人遇到此问题的地方。我正在运行诺顿，不过他们的修复说明是我的头脑。关于在Android Studio中设置代理的一些事情 - 从命令行或从设置＆gt; HTTP代理对话框。在那里，我有＆＃34;自动检测代理设置＆＃34;选择。如果我手动配置代理设置，我不知道输入什么信息。如果有人有任何关于我如何解决这个问题的建议（我做了清理和重建，这是本期的第二天）请分享！

答案 0 :(得分：2)
这意味着您的清单文件中包含一些错误的信息或格式错误的信息，这就是您的应用无法识别您的权限的原因。只需确保已使用任何格式错误的数据清理ANDROIDMANIFEST文件。
它可以工作，所有权限都应该在Application标签
之外在manifest标记
下方移动uses-permission外部应用程序 <uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
按上述方式行事
