安全异常崩溃

Question

我的 android 应用程序正在使用 firebase 并且需要访问互联网，因此在我的清单中我设置了互联网许可，但是 logcat 似乎不这么认为。

这是我的清单文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.powerofpixels.chipin"
          xmlns:android="http://schemas.android.com/apk/res/android">

    <permission android:name="android.permission.INTERNET"/>

    <application
        android:name=".Chipin"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".ui.activities.BirthdayActivity">
        </activity>
        <activity
            android:name=".ui.activities.AuthenticateActivity"
            android:theme="@style/Theme.AppCompat.NoActionBar">
            <intent-filter>
                <category android:name="android.intent.category.LAUNCHER"/>

                <action android:name="android.intent.action.MAIN"/>
            </intent-filter>
        </activity>
    </application>

</manifest>

错误信息如下：

Process: com.powerofpixels.chipin, PID: 4044 java.lang.SecurityException: Permission denied (missing INTERNET permission?) at java.net.InetAddress.lookupHostByName(InetAddress.java:451) at java.net.InetAddress.getAllByNameImpl(InetAddress.java:252) at java.net.InetAddress.getAllByName(InetAddress.java:215) at java.net.Socket.tryAllAddresses(Socket.java:109) at java.net.Socket.(Socket.java:178) at java.net.Socket.(Socket.java:150) at javax.net.ssl.SSLSocket.(SSLSocket.java:764) at com.android.org.conscrypt.OpenSSLSocketImpl.(OpenSSLSocketImpl.java:186) at com.android.org.conscrypt.OpenSSLSocketFactoryImpl.createSocket(OpenSSLSocketFactoryImpl.java:68) at com.firebase.tubesock.WebSocket.createSocket(WebSocket.java:317) at com.firebase.tubesock.WebSocket.run(WebSocket.java:117) Caused by: android.system.GaiException: android_getaddrinfo failed: EAI_NODATA (No address associated with hostname) at libcore.io.Posix.android_getaddrinfo(Native Method) at libcore.io.ForwardingOs.android_getaddrinfo(ForwardingOs.java:55) at java.net.InetAddress.lookupHostByName(InetAddress.java:438) at java.net.InetAddress.getAllByNameImpl(InetAddress.java:252) at java.net.InetAddress.getAllByName(InetAddress.java:215) at java.net.Socket.tryAllAddresses(Socket.java:109) at java.net.Socket.(Socket.java:178) at java.net.Socket.(Socket.java:150) at javax.net.ssl.SSLSocket.(SSLSocket.java:764) at com.android.org.conscrypt.OpenSSLSocketImpl.(OpenSSLSocketImpl.java:186) at com.android.org.conscrypt.OpenSSLSocketFactoryImpl.createSocket(OpenSSLSocketFactoryImpl.java:68) at com.firebase.tubesock.WebSocket.createSocket(WebSocket.java:317) at com.firebase.tubesock.WebSocket.run(WebSocket.java:117) Caused by: android.system.ErrnoException: android_getaddrinfo failed: EACCES (Permission denied) at libcore.io.Posix.android_getaddrinfo(Native Method) at libcore.io.ForwardingOs.android_getaddrinfo(ForwardingOs.java:55) at java.net.InetAddress.lookupHostByName(InetAddress.java:438) at java.net.InetAddress.getAllByNameImpl(InetAddress.java:252) at java.net.InetAddress.getAllByName(InetAddress.java:215) at java.net.Socket.tryAllAddresses(Socket.java:109) at java.net.Socket.(Socket.java:178) at java.net.Socket.(Socket.java:150) at javax.net.ssl.SSLSocket.(SSLSocket.java:764) at com.android.org.conscrypt.OpenSSLSocketImpl.(OpenSSLSocketImpl.java:186) at com.android.org.conscrypt.OpenSSLSocketFactoryImpl.createSocket(OpenSSLSocketFactoryImpl.java:68) at com.firebase.tubesock.WebSocket.createSocket(WebSocket.java:317) at com.firebase.tubesock.WebSocket.run(WebSocket.java:117)

为什么会崩溃？谢谢。

Answer 1

您的清单中需要 uses-permission 而不是 permission 元素。

Answer 2

哦！你有一个小错字！

改变

<permission android:name="android.permission.INTERNET"/>

至

<uses-permission android:name="android.permission.INTERNET" />

Answer 3

是 "uses-permission" 而不是 "permission"。用以下行替换您的权限行

<uses-permission android:name="android.permission.INTERNET" />
