Question

我的应用程序在除Pie版本之外的所有android版本中都运行良好。在Pie中，它显示没有互联网连接，而我通过Wifi和移动数据进行了检查。此问题与Pie版本有关。

i尝试以下解决方案：

    android:usesCleartextTraffic="true"
    android:networkSecurityConfig="@xml/network_security_config"

但是两个都没有。

这是我的“登录”按钮代码，其中包含在OnFailure中

private void onLoginUser(String email, String password) {

    Call<LoginModel> call = ApiClient.getClientInstance().getClientService().userlogin(email, password);

    call.enqueue(new Callback<LoginModel>() {

        @Override
        public void onResponse(Call<LoginModel> call, Response<LoginModel> response) {
            mProgressBar.setVisibility(View.GONE);

            LoginModel jsonLoginResult = response.body();

            if (response.code()== 200)  {
                Log.e("Response", response.code() + "");
            }
            if (response.code() == 400 ) {
                Utility.getInstance(LoginActivity.this).showSnackBarLong(response.message(), mLoginActivity);
                return;
            }
            if (response.code() == 404 ) {
                Utility.getInstance(LoginActivity.this).showSnackBarLong(response.message(), mLoginActivity);
                return;
            }
            if (response.code() == 500 ) {
                Utility.getInstance(LoginActivity.this).showSnackBarLong(response.message(), mLoginActivity);
                return;
            }
            if (jsonLoginResult == null ) {
                Utility.getInstance(LoginActivity.this).showSnackBarLong("Data not found", mLoginActivity);
                return;
            }

尝试下面的两件事，从您的应用程序标记中删除networkSecurityConfig，然后在您的应用程序标记中添加以下代码，然后尝试

 <application
        android:name=".MyApplication"
        android:allowBackup="true"
        android:enabled="true"
        android:icon="@drawable/icon"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:theme="@style/generalnotitle"
        android:usesCleartextTraffic="true">
<uses-library
    android:name="org.apache.http.legacy"
    android:required="false" />
