exception when trying to update records in the database

exception when trying to update records in the database - android

what i am trying to do is updating the records where it will search for the itemnumber and use is id to change the shelfnumber in another table based on what is in the edittext
this is the error i get when i tries to update the record
java.sql.SQLException: Incorrect syntax near the keyword 'file'.
and that happends at my public class and on my preparedStatement.executeUpdate();
public class UpdatePro extends AsyncTask<String, String, String> {

How to retrieve varbinary(max) image from SQL Server in android?

I am developing an android application in which I want to retrieve the image stored in SQL server database as shown in screenshot:
I have written a code for that but application will only retrieve the title column value and successfully shows in textview but in imageview nothing displays.Every kind of help is appreciated. Below is my code for that:
public class Menu_listen extends Fragment implements View.OnClickListener {
Connection con;
TextView t;
ImageView img;
String un,pass,db,ip,in;
private String abc;
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
getActivity().setTitle("abc");
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
final View InputFragmentView = inflater.inflate(R.layout.menu_1, container, false);
t = (TextView) InputFragmentView.findViewById(R.id.track_title);
img=(ImageView) InputFragmentView.findViewById(R.id.track_image);
ip = "192.168.***.**";
in="SQLEXPRESS";
db = "Testaudio";
un = "**";
pass = "****";
Check check1 = new Check();// this is the Asynctask, which is used to process in background to reduce load on app process
check1.execute("");
return InputFragmentView;
}
public String getAbc() {
return abc;
}
public void setAbc(String abc) {
this.abc = abc;
}
public class Check extends AsyncTask<String,String,String>
{
String z = "";
Boolean isSuccess = false;
#Override
protected void onPreExecute()
{
}
#Override
protected void onPostExecute(String r)
{
if(isSuccess)
{
Toast.makeText(getActivity() , "Successfull" , Toast.LENGTH_SHORT).show();
t.setText(getAbc());
byte[] decodeString = Base64.decode(r, Base64.DEFAULT);
Bitmap decodebitmap = BitmapFactory.decodeByteArray(decodeString, 0, decodeString.length);
img.setImageBitmap(decodebitmap);
}
}
#Override
protected String doInBackground(String... params)
{
try
{
con = connectionclass(un, pass, db, ip,in);
if (con == null)
{
z = "Check Your Internet Access!";
}
else
{
String query = "select * from getImg";
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(query);
if(rs != null && rs.next())
{
z = "successful";
isSuccess=true;
setAbc(rs.getString(3));
z=rs.getString(2);
}
con.close();
}
}
catch (Exception ex)
{
isSuccess = false;
z = ex.getMessage();
}
return z;
}
}
#SuppressLint("NewApi")
public Connection connectionclass(String user, String password, String database, String server,String instance) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
Connection connection = null;
String ConnectionURL = null;
try {
Class.forName("net.sourceforge.jtds.jdbc.Driver");
ConnectionURL = "jdbc:jtds:sqlserver://" + server + "/" + database + ";instance=" + instance + ";user=" + user + ";password=" + password + ";";
connection = DriverManager.getConnection(ConnectionURL);
} catch (SQLException se) {
Log.e("error here 1 : ", se.getMessage());
t.setText(se.getMessage());
} catch (ClassNotFoundException e) {
Log.e("error here 2 : ", e.getMessage());
t.setText(e.getMessage());
} catch (Exception e) {
Log.e("error here 3 : ", e.getMessage());
t.setText(e.getMessage());
}
return connection;
}
}

Here the code i used for my app
This code will take a image from url and convert is to a byte array
byte[] logoImage = getLogoImage(IMAGEURL);
private byte[] getLogoImage(String url){
try {
URL imageUrl = new URL(url);
URLConnection ucon = imageUrl.openConnection();
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
ByteArrayBuffer baf = new ByteArrayBuffer(500);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte) current);
}
return baf.toByteArray();
} catch (Exception e) {
Log.d("ImageManager", "Error: " + e.toString());
}
return null;
}
To save the image to db i used this code.
public void insertUser(){
SQLiteDatabase db = dbHelper.getWritableDatabase();
String delSql = "DELETE FROM ACCOUNTS";
SQLiteStatement delStmt = db.compileStatement(delSql);
delStmt.execute();
String sql = "INSERT INTO ACCOUNTS (account_id,account_name,account_image) VALUES(?,?,?)";
SQLiteStatement insertStmt = db.compileStatement(sql);
insertStmt.clearBindings();
insertStmt.bindString(1, Integer.toString(this.accId));
insertStmt.bindString(2,this.accName);
insertStmt.bindBlob(3, this.accImage);
insertStmt.executeInsert();
db.close();
}
To retrieve the image back this is code i used.
public Account getCurrentAccount() {
SQLiteDatabase db = dbHelper.getWritableDatabase();
String sql = "SELECT * FROM ACCOUNTS";
Cursor cursor = db.rawQuery(sql, new String[] {});
if(cursor.moveToFirst()){
this.accId = cursor.getInt(0);
this.accName = cursor.getString(1);
this.accImage = cursor.getBlob(2);
}
if (cursor != null && !cursor.isClosed()) {
cursor.close();
}
db.close();
if(cursor.getCount() == 0){
return null;
} else {
return this;
}
}
Finally to load this image to a imageview

How to update the Recylerview View items after displayed First Json URL In android

I having a problem update the Item in Recycler View.I will explain clearly about my problem.
I am using two Json URL's first Json URL can send the items to model class.
after completed this called the adapter, then update the second Json URL items with the adapter by using setter model class.
so that's why called adapter.notifyitemchanged, but only one time can updated items next time while looping doesn't update the items display empty for second time.
Code:
public void servicecallsingle(String list, final int pin) {
url = Constants.singleproducturl + list;
JsonObjectRequest request1 = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener < JSONObject > () {
#Override
public void onResponse(JSONObject response) {
JSONObject response1 = response;
if (response1 != null) {
// int status=jsonObject.optInt("status");
String status = response1.optString("status");
if (status.equalsIgnoreCase("200")) { //check the status 200 or not
try {
productpath = response1.getString("productPath");
} catch (JSONException e) {
e.printStackTrace();
}
try {
JSONObject responses = response1.getJSONObject("response");
jsonarray = responses.getJSONArray(DATA);
if (jsonarray.length() > 0) {
// looping through json and adding to movies list

Anyone solve this problem glad to appreciate.
Thanks in advance

The problem is volley doesn't wait for the request to be completed. So as the first call is made within seconds other call will be also made. So, you need to create an interface which will be called when the first webservice is called, and than in interface call other webservice and than notifyDataSet.

url = Constants.singleproducturl + list;

Android: Loading large txt file(120k lines) from raw folder has delay the first time

I am using an AsyncTask to parse a very large txt file in my application and i noticed something weird: The first time this AsyncTask is called it takes very long time to finish(10-20 seconds) and the next times it's almost instantly.
So i am guessing i should somehow load the txt file into memory when the app starts and go from there.
Is there any ways to do this or is this the right thing to do in the first place?
Should some kind of cache implementation solve my problem?
Would it be a good idea to use the Android Cache system?
This is my AsyncTask for referece:
public class AnalyzeReviewsAsync extends AsyncTask<ArrayList<Place.Review>, String, String> {

Why can't I update my EditText in onPostExecute with Geocoder in the AsyncTask?

I am trying to reverse geocode inside an AsyncTask to get the address of the current location. I want to set the EditText to the address as default when starting the activity. My problem is I am unable to do this in onPostExecute(), however, I can do it in runOnUiThread() inside doInBackground(). Why is this?
AsyncTask:
protected String doInBackground(Void ...params) {
Geocoder geocoder = new Geocoder(AddSpot.this, Locale.getDefault());
List<Address> addresses = null;
try {
// Call the synchronous getFromLocation() method by passing in the lat/long values.
addresses = geocoder.getFromLocation(currentLat, currentLng, 1);
}
catch (IOException e)
{
e.printStackTrace();
}
if (addresses != null && addresses.size() > 0)
{
Address address = addresses.get(0);
// Format the first line of address (if available), city, and country name.
final String addressText = String.format("%s, %s, %s",
address.getMaxAddressLineIndex() > 0 ? address.getAddressLine(0) : "",
address.getLocality(),
address.getCountryName());
System.out.println(addressText);
return addressText;
}
return null;
}
protected void onPostExecute(String address) {
EditText addrField=(EditText)findViewById(R.id.addr);
addrField.setText(address);
}
That does not work. However, when I stick a runOnUiThread in it, it works:
if (addresses != null && addresses.size() > 0)
{
Address address = addresses.get(0);
// Format the first line of address (if available), city, and country name.
final String addressText = String.format("%s, %s, %s",
address.getMaxAddressLineIndex() > 0 ? address.getAddressLine(0) : "",
address.getLocality(),
address.getCountryName());
runOnUiThread(new Runnable()
{
#Override
public void run()
{
EditText addrField=(EditText)findViewById(R.id.addr);
addrField.setText(addressText);
}
});
System.out.println(addressText);
return addressText;
}
UPDATE
After some debugging it appears that onPostExecute is never called at all no matter what I do.
Things I have tried:
Log information inside onPostExecute: Does not appear
Remove the entire logic inside doInBackground so it's like this return "hello" : onPost still does not execute

You did not put #Override above onPostExecute. Also asynctask object must to be created inside UI thread.
EDIT: Your edittextis not updated, becauseit is consumedimidiatly after post execute is finished.
1) write EditText addrField; as class variable of activity class.
2) find reference to it in onCreate().
3) on your original onpostexecute should remain only addrField.setText(address);
there is my class, where textfields are updated from onPostexecute without any problems
