Question

我开始在Android上的应用程序上工作，所以我没有太多。到目前为止，我所拥有的只是一个WebView。我在Android Studio中创建了该项目，然后将我的项目设置为Android InstantApp。我不确定为什么/如何做，但是我猜是在创建项目时我忽略了它的选项。

我从WebView收到一条错误消息，说net :: ERR_CLEARTEXT_NOT_PERMITTED。当我搜索错误时，我看到当一个应用程序是InstantApp时，WebViews只能加载HTTPS站点，而不能加载HTTP站点。

此应用程序的目的是成为仅用于一个站点的极其简单的Flash播放器。这样可以在需要Flash的游戏中获得更好的性能。该游戏位于darkorbit.com，即HTTPS。

MainActivity.java：

package com.tylerr147.darkorbit;

import android.content.ComponentName;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebSettings;
import android.webkit.WebView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        WebView wv = findViewById(R.id.webView1);
        wv.loadUrl("https://darkorbit.com/");
        wv.setWebViewClient(new CustomWebViewClient());
        WebSettings webSettings = wv.getSettings();
        webSettings.setJavaScriptEnabled(true);
        webSettings.setPluginState(WebSettings.PluginState.ON);

    }
}

和CustomWebViewClient.java

package com.tylerr147.darkorbit;

import android.webkit.WebView;
import android.webkit.WebViewClient;

public class CustomWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }
}

我的问题：如何将我的应用程序禁用为InstantApp，或者如何使该WebView显示网站？

我觉得重要的是我还要提到其他一些细节：在显示WebView的应用程序中，它还显示“ http://darkorbit.com/处的网页”无法加载，原因是：净：: ERR_CLEARTEXT_NOT_PERMITTED

即使URL的字符串是硬编码的，也要注意“ {... {3}}的站点...”，而不是“ http://darkorbit.com/的站点...”，并说“ https://darkorbit.com/”。另外，我正在设置为运行Android 9的Google Pixel 2的模拟器上测试该应用。

任何帮助将不胜感激。谢谢。

Answer 1

解决方案：

在您的application标签中添加以下行：

android:usesCleartextTraffic="true"

如下所示：

<application
    ....
    android:usesCleartextTraffic="true"
    ....>

希望有帮助。

Answer 2

当您调用“ https://darkorbit.com/”时，服务器认为它缺少“ www”，因此它将调用重定向到“ http://www.darkorbit.com/”，然后再重定向到“ https://www.darkorbit.com/”，则您的WebView调用是由于它是“ http”调用，因此在首次重定向时被阻止。您可以改用“ https://www.darkorbit.com/”来解决问题。

# query all users in multiple OUs
(Get-ADOrganizationalUnit -Filter *).DistinguishedName |
ForEach{
    # Collect all members of the current OU
    $AccountNames = Get-ADUser -SearchBase $PSItem -Filter *

    # Process each member in the current OU collection
    ForEach($AccountName in $AccountNames)
    {
        "Processing $($AccountName.SamAccoutnName)`n"

        # Initialize properties needed for processing
        $UserOrg = $AccountName.DistinguishedName.split(",")[1]
        $MemberCheckOU = "OU=Admin-User-Accounts,OU=Administration,OU=ORG1,OU=$UserOrg,DC=domain,DC=net"
        $NonCompliantOU = "OU=Groups,OU=ORG1,OU=Information Assurance,OU=$UserOrg,DC=domain,DC=net"

        # Validate user file existence for the current user
        If(-Not (Test-Path -LiteralPath "\\domain.net\SYSVOL\domain.net\IA\$($AccountName.SamAccoutnName).pdf)"))

            Write-Warning -Message "$($($AccountName.SamAccoutnName).pdf) not found. Process group modify actions"       

            # If the current user is in the MemberCheckOU, add to the NonCompliantOU
            If(Get-ADPrincipalGroupMembership -Identity $($AccountName.SamAccoutnName) | Where-Object -Property DistinguishedName -Match $MemberCheckOU )
            { Add-ADGroupMember -Identity $NonCompliantOU -Members $($AccountName.SamAccoutnName) }
            Else
            {
                # Do something else
            }
        }
        Else
        { 
          # Notify that the file was found and no processing required
          Write-Host "$($AccountName.pdf) found. No further actions taken" -ForegroundColor Green }
    }
}

抱歉，发帖太晚重新启动计算机后，此功能正常工作

WebView显示ERR_CLEARTEXT_NOT_PERMITTED，尽管站点是HTTPS
