In the latest release of Google Play, Google removed the need to ask permission for internet as "most apps need it anyways nowadays". However, for users who have older versions, it is still recommended to leave the code below in your manifest
在最新版本的 Google Play 中，Google 取消了请求互联网许可的需要，因为“现在大多数应用程序都需要它”。但是，对于旧版本的用户，仍然建议将下面的代码保留在您的清单中
<uses-permission android:name="android.permission.INTERNET" />

If you want using Internet in your app as well as check the network state i.e. Is app is connected to the internet then you have to use below code outside of the applicationtag.
如果您想在您的应用程序中使用互联网并检查网络状态，即应用程序是否已连接到互联网，那么您必须在application标签之外使用以下代码。
For Internet Permission:
互联网许可：
<uses-permission android:name="android.permission.INTERNET" />
For Access network state:
对于接入网络状态：
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
Complete Code:
完整代码：
<uses-sdk

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

if just using internet then use-
如果只是使用互联网然后使用-
<uses-permission android:name="android.permission.INTERNET" />
if you are getting the state of internet then use also -
如果您正在获得互联网状态，那么也可以使用 -
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
just above the application tag.
就在应用程序标签上方。

forget about adding the permission into the manifest Add this code as a method
忘记将权限添加到清单中 将此代码添加为方法
public static boolean hasPermissions(Context context, String... permissions)
{
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null)
{
for (String permission : permissions)
{
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED)
{
return false;
}
}
}
return true;
}
and write this in your Main
并将其写入您的Main
int PERMISSION_ALL = 1;
String[] PERMISSIONS = {Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS, Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_SMS, Manifest.permission.CAMERA};
if (!hasPermissions(this, PERMISSIONS)) {
ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}
