问题描述
我已经搜索了所有解决方案并将其应用于我的项目.但是他们没有工作.我拒绝了此权限.我已将所有可能的权限放入清单文件中.请告诉我我的项目出了什么问题.
I have searched all solutions and applied into my project. But they are not working. I have this permission denied.I have put all those possible permission into manifest file. Please tell me what's wrong with my project.
public static void getGetResponse() {
InputStream inputStream = null;
try {
URL url = new URL("http://120.26.89.113:8080/common/qiniuToken");
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("GET");
String userPassword = "wehelper:***********";
byte[] encodedBytes = Base64.encode(userPassword.getBytes(), 0);
connection.setRequestProperty("Authorization", "Basic " + encodedBytes);
connection.connect();
int resCode = connection.getResponseCode();
if (resCode == 200) {
inputStream = connection.getInputStream();
}
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
StringBuilder out = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
out.append(line);
}
System.out.println(out.toString());//Prints the string content read from input stream
Log.d("myApp",out.toString());
reader.close();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
和我的manifest.xml
and my manifest.xml

推荐答案
您的<uses-permission>元素放置在错误的位置.它们必须在<application>元素的外部中，作为根<manifest>元素的直接子元素:
Your <uses-permission> elements are in the wrong place. They need to be outside the <application> element, as immediate children of the root <manifest> element:
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/MyMaterialTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
