Retrofit and SQlite how to remove lags

Retrofit and SQlite how to remove lags - android

I use Retrofit library for getting and parsing JSON from server.
All methods I run in MainActivity when Application is starting. And I have trouble when I check is Object(parsed from JSON) already exist in Data Base or not. Application is not responsing. What can I do?
here is MainActivity:

what you have done is calling endpoint async-ly and processing the heavy db operation in main thread.
You can do all these stuff in background thread using single AsyncTask.
Change your async retrofit endpoints to synchronous like:
void getPrograms(Callback<Programs>);
to
Programs myapi.getPrograms();
and a single async task like:
public class MyHeavyTask extends AsyncTask<Void, Void, Void> {
private final MYDBHelperFromApi DBHelperAPI;
private final MYapi myapi;
public MyHeavyTask(MYDBHelperFromApi DBHelperAPI, MYapi myapi) {
this.DBHelperAPI = DBHelperAPI;
this.myapi = myapi;
}
#Override
protected Void doInBackground(Void... params) {
HashMap<String, String> hashMap = myapi.getLanguages();
boolean valid = hashMap != null;// do other validation catch exceptions if needed
//Do response validation
//Add to your database
if (valid)
DBHelperAPI.addLanguages(hashMap);
//similarly
List<AsanaLevel> asanaLevels = myapi.getLevelList();
DBHelperAPI.addAsanaLevel(asanaLevels);
List<AsanaType> asanaTypes = myapi.getTypeList();
DBHelperAPI.addAsanaType(asanaTypes);
List<ProgramGoal> programGoals = myapi.getProgramGoalList();
DBHelperAPI.addProgramGoal(programGoals);
//Similarly others
return null;
}
}
Now execute the task in onCreate method like:
new MyHeavyTask(DBHelperAPI,myapi).execute();

This is a simple problem. You are only using
use for loop to iterate through all items like,
for(int i=0; i<datamodel.size(); i++){
doNormalPostOperation(i)
}
and in doNormalPostOperation method
public void doNormalPostOperation(int i) {
// PREVIOUS CODE
#Override
protected Map<String, String> getParams() {
params.put("id", datamodel.get(i).getINSURANCE_ID() + "");
// REMAINING PARAMS WITH SAME datamodel.get(i) item
}
}
which is causing that issue and only sending first item. You will need to iterate through all items to generate parameters and send to server, or else you can combine them to one json array and modify the code server side.

First you collect the Data from sqltables
/* Collecting Information */
public Cursor getAllData() {
String selectQuery = "Select * from "+TABLE_MEMBER;
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
return cursor;
}
public JSONObject createJsonObject(){
Cursor cursor = getAllData();
JSONObject jobj ;
JSONArray arr = new JSONArray();
cursor.moveToFIrst();
while(cursor.moveToNext()) {
jobj = new JSONObject();
jboj.put("Id", cursor.getInt("Id"));
jboj.put("Name", cursor.getString("Name"));
arr.put(jobj);
}
jobj = new JSONObject();
jobj.put("data", arr);
}
public void postJsonToServer(){
JSONObject js = createJsonObject();
String url = "YOUR -- Post Url";
JsonObjectRequest jsonObjReq = new JsonObjectRequest(
Request.Method.POST,url, js,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
msgResponse.setText(response.toString());
hideProgressDialog();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
hideProgressDialog();
}
}) {
/**
* Passing some request headers
* */
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
}

You can go through this:
Get all the data which you want to send, via select query and store this data in a array list.
Using GSON library you can convert that arraylist into json data
Now you have to create an API which receive that json data and parse it and insert every record to database.
On the app end you have to hit that API and pass json data to it.

unable to send data to database, dont know whats wrong with the code

this code was working fine earlier and database have tables made back in 2017, but somehow these are not working any more, unable to create tables in database and retrieve data from it. Android studio throws no error.Stuck with this from last 1 week.

Store all the information at once using Realm in Background thread Android

I am developing an android app, where I am using Relam as local Database. I have rest api one for all the user information and other is for news information. I have two buttons. one for showing the user information and other is for showing the news information. Now, with my code what is done, after login, I need to click the button at first for user information and news information accordingly and then I can see those images and news. but if I connection off, just after login, the data is not showing in the view. I am explaining my code in detail.Also I am having problem in image loading. How can I Make the funtionality so that user can get all the information just after login.I am reallly sorry for such a long code. It would be really helpful for me if someone tell me how can I modify my code to store all data in background thread, so that user get all information just after login.
The part of the login page where I want to start
private void loginUser(final String mEmail, final String mPassword) {
final GlobalClass globalClass = new GlobalClass();
globalClass.setEmail_info( mEmail );
setFilePath();
RequestQueue queue = Volley.newRequestQueue( LoginPage.this );
StringRequest strReq = new StringRequest( Request.Method.POST,
LOGIN_URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d( TAG, "Register Response: " + response.toString() );
//parse your response here
if (response.contains( "overview" )) {
showProgress( true );
globalClass.setImage_urlpath( Constants.HTTP.PHOTO_URL + mEmail);
String str = globalClass.readDatafromStorage();
Log.d("----After Login---",str);
if ( !str.contains("ACTIVATE") ) {
Log.d( "----After Login---", "After Login" );
}
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString(KEY_EMAIL, mEmail);
editor.putString(KEY_PASSWORD, mPassword);
editor.commit();
showProgress(false);
Intent loginIntent = new Intent(LoginPage.this, MainOptionPage.class);
loginIntent.putExtra(KEY_EMAIL, mEmail);
startActivity(loginIntent);
} else {

}
adapter = new NewsAdapter(mNewsList,getApplicationContext());
Log.d( "adapter value is"+"", String.valueOf( adapter ) );
recyclerView.setAdapter(adapter);

}

To do your database processing on a background thread using Volley, you need to extend Request<T> and do the Realm write in parseNetworkResponse method.
public class RealmGsonObjectRequest<T, M extends RealmModel> extends Response<Void> {
...
#Override
protected Response<Void> parseNetworkResponse(
NetworkResponse response) {
try {
String json = new String(response.data,
HttpHeaderParser.parseCharset(response.headers));
T data = gson.fromJson(json, clazz);
// write the downloaded data into the Realm on bg thread
try(Realm r = Realm.getDefaultInstance()) {
M model = mapper.toModel(data);
r.executeTransaction((realm) -> {
realm.insertOrUpdate(model);
});
}
return Response.success(null,
HttpHeaderParser.parseCacheHeaders(response)
);
} // handle errors
}
You might need a RealmGsonListRequest as well.
public class RealmGsonListRequest<T, M extends RealmModel> extends Response<Void> {
...
#Override
protected Response<Void> parseNetworkResponse(
NetworkResponse response) {
try {
String json = new String(response.data,
HttpHeaderParser.parseCharset(response.headers));
List<T> data = gson.fromJson(json, new TypeToken<ArrayList<T>>() {}.getType());
// write the downloaded data into the Realm on bg thread
try(Realm r = Realm.getDefaultInstance()) {
M model = mapper.toModel(data);
r.executeTransaction((realm) -> {
realm.insertOrUpdate(model);
});
}
return Response.success(null,
HttpHeaderParser.parseCacheHeaders(response)
);
} // handle errors
}
For more information, refer to the official Volley tutorial on how to create a custom Volley request type.

How to do Filter listview in android?

Clarification:
How do to Filter while click the Filter Button On DashBoard Fragment. Please Suggest the way. I here by attached My Filter design also.
Dashboard Fragment--> Filter Button-> Filter screen-> the Filtered results should view on DashBoard Fragment.
Once click the apply Button Based on the input from Filter screen it filters the list view the result comes from back end team. I have to display that result on Dashboard Fragment.
Kindly please clarify this Filter concept.

You can use a web view to render your google form within the application.
If for some reason you prefer not to use a web view, it is also possible to use the 'keys' in a google form(obtained via 'inspect element') to integrate the same with your application. Here is a link detailing the steps.

You can use the following in your onCreate():
progressDialog = new ProgressDialog(this);
progressDialog.setCancelable(false);
progressDialog.setMessage("Loading...");
queue = Volley.newRequestQueue(getApplicationContext());
submit.setOnClickListener(view -> {
postData(edit_name.getText().toString().trim(), edit_email.getText().toString().trim(),
edit_number.getText().toString().trim(), edit_remarks.getText().toString().trim());l
});
Also create a function in the activity as follows and in my Google Forms I have 4 entries to make which are name, phone, email and remark:
public void postData(final String name, final String email, final String phone, final String remark) {
progressDialog.show();
StringRequest request = new StringRequest(Request.Method.POST, Constants.url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("TAG", "Response: " + response);
if (response.length() > 0) {
Snackbar.make(btn_submit, "Successfully Posted", Snackbar.LENGTH_LONG).show();
finish();
} else {
Snackbar.make(btn_submit, "Try Again", Snackbar.LENGTH_LONG).show();
}
progressDialog.dismiss();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
progressDialog.dismiss();
Snackbar.make(btn_submit, "Error while Posting Data", Snackbar.LENGTH_LONG).show();
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<>();
params.put(Constants.nameField, name);
params.put(Constants.emailField, email);
params.put(Constants.phoneField,"+91"+phone);
params.put(Constants.remarkField, remark);
return params;
}
};
request.setRetryPolicy(new DefaultRetryPolicy(
50000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
queue.add(request);
}
Create a Java class Constants where you enter the url and id of the entries in forms:
public class Constants {
// Google Forms URL .. replace with yours
public static final String url = "https://docs.google.com/forms/d/e/1FAIpQLSf65J3RmZS6QBg_TrsZZFx9s0l6109Q4E6PvUjuZ9go6D9l2g/formResponse";
// Google Form's Column ID
public static final String nameField = "entry.2006520554";
public static final String phoneField = "entry.1196974658";
public static final String emailField = "entry.1054781291";
public static final String remarkField = "entry.839339060"; }
Entry ids can be found by inspecting your Google Forms. For more details refer to the this link.
