我不知道我在哪里面对错误。我的Android手机是Redmi MI Max，Android版本，6.0.1。我使用Asynctask后台线程进行API调用并成功使用json数据并保存数据，线程在Postexecute上完全保存成功无法工作......我没有使用任何指纹访问。但它显示指纹错误。
public void userLogin(String schoolCode, String userName, String password, String deviceId) {
try {
boolean isDataSet = false;
String url = Constants.MAIN_SERVER_URL;
JSONObject jsonObject = new JSONObject();
jsonObject.put(Params.SCHOOLCODE, schoolCode);
jsonObject.put(Params.USERNAME, userName);
jsonObject.put(Params.PASSWORD, password);
jsonObject.put(Params.DEVICE_ID, deviceId);
api.call(url, jsonObject, new Api.CallBack() {
@Override
public void done(String url, JSONObject jsonObject, AjaxStatus status) {
boolean isDataSet = false;
try {
if (jsonObject != null) {
int statusCode = jsonObject.getInt(Params.STATUS);
if (statusCode == StatusCodes.SUCCESS) {
isDataSet = true;
JSONObject dataObject = jsonObject.getJSONObject(Params.DATA);
new UserLogInInfoSaving(dataObject).execute();
} else {
String message = Utils.getValidStringFromJSON(jsonObject, Params.MESSAGE);
JSONObject jsonErrorObj = new JSONObject();
jsonErrorObj.put(Params.MESSAGE, message);
Log.e("ERRROR", " IN DASHBOARD INFORMATION ".concat(status.getMessage()));
if (dataCompletedAction != null) {
dataCompletedAction.onRecordsCompleted(jsonErrorObj);
}
}
} else {
Toast.makeText(ctx, status.getMessage(), Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (!isDataSet) {
Log.e("ERRROR", " IN DASHBOARD INFORMATION ".concat(status.getMessage()));
if (dataCompletedAction != null) {
dataCompletedAction.onRecordsCompleted(null);
}
}
}
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
检查用户登录，我将记录保存到数据库
private class UserLogInInfoSaving extends AsyncTask<Void, Void, Void> {
JSONObject jsonObject;
UserLogInInfoSaving(JSONObject jsonObject) {
this.jsonObject = jsonObject;
}
@Override
protected Void doInBackground(Void... params) {
DBSchools dbSchools = null;
try {
// Saving school information
Constants.ACTIVE_USER_ID = Utils.getValidStringFromJSON(jsonObject, Params.USER_ID);
if (jsonObject.has(Params.SCHOOL_INFO)) {
JSONObject jsonSchoolInfoObj = jsonObject.getJSONObject(Params.SCHOOL_INFO);
String newSchoolCode = Utils.getValidStringFromJSON(jsonSchoolInfoObj, Params.SCHOOLCODE);
if(newSchoolCode!=null && !newSchoolCode.equals("NA")) {
dbSchools=DBSchools.set(newSchoolCode, isFirstSchool(), jsonSchoolInfoObj);
if(dbSchools!=null) {
Constants.CURRENT_SCHOOL_CODE = dbSchools.getSchoolCode();
Constants.SERVER_URL = dbSchools.getSchoolUrl();
DBParent.set(Constants.CURRENT_SCHOOL_CODE, Constants.SERVER_URL, Constants.ACTIVE_USER_ID, jsonObject);
}
}
}
} catch (Exception e){
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void v) {
super.onPostExecute(v);
try {
JSONObject jsonSchoolInfoObj = jsonObject.getJSONObject(Params.SCHOOL_INFO);
String newSchoolCode = Utils.getValidStringFromJSON(jsonSchoolInfoObj, Params.SCHOOLCODE);
String parentId = Utils.getValidStringFromJSON(jsonObject, Params.USER_ID);
JSONArray jsonArray = Utils.getValidJSONArrayFromJSON(jsonObject, Params.STUDENT_INFO);
new StudentInfoSaving(jsonArray, Constants.SERVER_URL, newSchoolCode, parentId).execute();
}catch (Exception e){
e.printStackTrace();
}
}
当我从post执行中删除代码并在runOnUiMethod（）的帮助下在UserLogInInfoSaving类中的doInBackgroud方法上执行时，它运行正常。但当它转到同一类的postExecute（）方法时会出现错误。
有人见过这种错误吗？帮助我。我仍然坚持这个问题。帮助将不胜感激
答案 0 :(得分：0)
启动调试模式，这是由于你的Params.SCHOOL_INFO将空值传递给jsonobject而导致在post执行方法中使用jsonobject引起的
