Question

我试图调用httpClient并且响应是＆＃34;权限被拒绝（缺少INTERNET权限？）＆＃34;。在Android的普通浏览器中，我可以毫无问题地打开URL。

 public static String getHttpResponse(URI uri) {
    StringBuilder response = new StringBuilder();
    try {

        HttpGet get = new HttpGet();
        get.setURI(uri);
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpResponse httpResponse = httpClient.execute(get);

        if (httpResponse.getStatusLine().getStatusCode() == 200) {
            Log.d("demo", "HTTP Get succeeded");

            HttpEntity messageEntity = httpResponse.getEntity();
            InputStream is = messageEntity.getContent();
            BufferedReader br = new BufferedReader(new InputStreamReader(is));
            String line;
            while ((line = br.readLine()) != null) {
                response.append(line);
            }
        }
    } catch (Exception e) {
        Log.e("demo", e.getMessage());
    }
    Log.d("demo", "Done with HTTP getting");
    return response.toString();
}

catch日志告诉我错误：

java.lang.SecurityException: Permission denied (missing INTERNET permission?)
libcore.io.GaiException: getaddrinfo failed: EAI_NODATA (No address associated with hostname)
Permission denied (missing INTERNET permission?)

在我的Manifest中是权限集：

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

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <uses-feature android:name="android.hardware.camera" android:required="true" />

    <activity
        android:name=".main"
        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>

Answer 1

您是否尝试在应用标记上方提供权限？

您应该注意在 Manifest.xml中定义标记的订单。

见Manifest的structure。

<强>编辑：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<application
    ...>
</application>

<强>详细信息：

在清单中定义标签的顺序：

权限
应用
接收方，服务，元数据

Answer 2

权限必须在应用程序标记之外。所以你需要移出你的权限

<uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<application
    ... >
</application>

了解 Structure of the Manifest File 。语法是

<manifest>

    <uses-permission />

    <application>
        ....
    </application>

</manifest>

Answer 3

Permissions不应该在Application Tag中..您必须将其作为Manifest的孩子。

Answer 4

将您的用户权限标记放在应用程序标记上方。链接：http://developer.android.com/guide/topics/manifest/uses-feature-element.html

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="..." >
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <uses-feature android:name="android.hardware.camera" android:required="true" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >


    <activity
        android:name=".main"
        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>

Answer 5

右

<uses-permission/>
    <application/>

错

<application>

<uses-permission/>
<application/>

Answer 6

试试这个您授予权限正确但权限必须在应用程序标记维护标记的顺序

  <manifest>
      <uses-permission />
      <application>
       ....
      </application>
      <receiver> </receiver>
      <service> </service>
</manifest>

your code is like this way

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

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-feature android:name="android.hardware.camera" android:required="true"/>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <activity
        android:name=".main"
        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>

Answer 7

权限必须是清单标题的直接子项。

权限被拒绝（缺少INTERNET权限？）：但是获得了许可
