Question

我已经制作了一个请求互联网权限的应用，但它在应用信息位置没有显示请求的权限。这是清单文件。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.myartsonline.bharath.lowloss">
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

这是我的MainActivity.java文件

Answer 1

无需检查互联网许可。

并且$response_data=array('response'=>0,'message'=>'This is already added in db'); echo json_encode($response_data); die;需要一个名为{"response":"already added","message":"This is already added in db"}

的回调

Answer 2

如果您希望自己的应用检查互联网连接，可以使用此代码

boolean isInternet = isInternetOn();
if (isInternet) {  //write your code here    }

然后在您想要检查上述方法的互联网连接呼叫的任何地方

@Plan:name('ExecutionPlan')

@Import('InputStream:1.0.0')
define stream InputStream (id string, temp int);

/* Filter events with temp > 90 */
from InputStream[temp > 90]
insert into CriticalStream;

/* Aggregate within a lengthBatch window, while group by id*/
from CriticalStream#window.lengthBatch(2)
select id, temp, count() as count
group by id
insert into EventReporter;

/* Just for logging the result in the cosole */
from EventReporter#log("Logging EventReporter : ")
insert into #temp;

Android未显示权限
