Android 用户登录问题。仅处理登录屏幕。用户可以'；t登录

由于之前我将android studio更新为最新版本，所以我的应用程序运行良好，但现在我无法登录我的应用程序。 在给出用户名和密码后，仅处理登录屏幕，而不登录

有什么问题，请帮忙

这是上传数据的方法

 public void uploadGroupData() {
    CommonMethod.writeToFile(new Gson().toJson(groupSyncUpData));

    RequestParams params = new RequestParams();

    params.put("group_data", new Gson().toJson(groupSyncUpData));

    Log.e("ParamsJason : ", "" + params);

    PhpConnectivity.getClient().post(CommonConst.GROUP_TEST_URL, params, 
                                 new 
            AsyncHttpResponseHandler() {
        @Override
        public void onStart() {
            super.onStart();
            progressDialog.setTitle("Group Sync Up");
            progressDialog.setMessage("Group  Data Uploading...");
            progressDialog.setCancelable(false);
            progressDialog.show();
        }

        @Override
        public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
            String response = new String(responseBody);
            if (response.trim().equalsIgnoreCase(RESPONSE_SUCCESS)) {
                progressDialog.dismiss();
                CommonMethod.alert(SyncUpActivity.this
                        , "Group Sync Up:", "Success");
                dbHandler.updateGroupSync(groupSyncUpData.getGroup().getGroupId(), 1);
                recAdapter.getItemList().remove(groupSyncUpData.getGroup());
                recAdapter.notifyDataSetChanged();
                groupSyncUpData = null;
            } else {
                Log.e(TAG, "onFailure: " + response);
                progressDialog.dismiss();
                CommonMethod.alert(SyncUpActivity.this
                        , "Group Sync Up Failure:", "Response: " + response);
            }

        }

        @Override
        public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
            if (responseBody == null) {
                CommonMethod.alert(SyncUpActivity.this
                        , "Connectivity Error:", "Try Again!");
                progressDialog.dismiss();
                return;
            }
            String response = new String(responseBody);
            Log.e(TAG, "onFailure: " + response);
            progressDialog.dismiss();
            CommonMethod.alert(SyncUpActivity.this
                    , "Group Sync Up Failure:", "Response: " + response);

        }
    });
}

用于登录内部登录活动的方法

 @Override

    final Login login = new Login();
    if (view == loginBtn) {
        progressDialog = new ProgressDialog(LoginActivity.this);
        progressDialog.setMessage("logging in...");
        progressDialog.show();
        progressDialog.setCancelable(false);

        username = UsernameEdt.getText().toString();
        password = PasswordEdt.getText().toString();
        Log.e(TAG, "onClick: --" + username + "---" + password);

        if (CommonMethod.isNetworkAvailable2(this)) {
            OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
                    .connectTimeout(45000, TimeUnit.SECONDS)

                    .writeTimeout(45000, TimeUnit.SECONDS)
                    .build();
            AndroidNetworking.post(CommonConst.LOGIN_URL_TEST)
                    .addBodyParameter("Username", username)
                    .addBodyParameter("Password", password)

在新的Android Studio版本中，您需要检查安全性。有关这一点，请参阅此链接。这种问题在Android 8和9中都会出现

您还需要使用安全的URL，如https://。如果您使用的是http://则会出现此类问题

替换相关匹配中的以下代码

buildscript {

repositories {
    google()
    jcenter()
    maven { url 'https://maven.fabric.io/public' }
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'
    classpath 'io.fabric.tools:gradle:1.+'
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

---

}

检查您的日志中是否有问题检查后端中缺少的内容。检查响应请提供您的代码。人们无法猜测。@VivekMishra logcat中没有错误。你需要共享你的代码，然后检查上面的链接安全配置。我更新了我的android studio，现在收到警告，请查看我的问题，并查看android studio SS@ankurokay，了解目前没有可用的解决方案，以便临时解决方案可以在类路径中降级您的gradle版本。我认为您正在使用3.3.0。然后将此版本降级到3.2.1。它可能会暂时帮助你。它可能来自Crashlytics插件。我们需要等待Fabric（现在是Google）人员的更新。与此同时，它只是一个警告——尽管这是一个非常令人分心和恼人的警告——所以你可以（尝试）忽略它。我怎样才能降级？更新了我的问题，请检查我的gradle文件@安克尔
