I have a trouble in my app retrieving my data from parse.com
I just wanted to recover data from website in an ArrayList made with a custom class, for using later in my app
Here is code but I can't test it on my emulator because my app crashes on boot, despite I don't have coding errors
PS: I'm very new in android coding, so any help is well accepted!
final int duration = Toast.LENGTH_SHORT;
ParseQuery<ParseObject> queryP = ParseQuery.getQuery("Menu");
queryP.orderByAscending("Id");
queryP.findInBackground(new FindCallback<ParseObject>() {
#Override
public void done(List<ParseObject> MenuList, ParseException e) {
int Id_c;
String Image_c;
String Name_c;
String Description_c;
String Type_c;
Double Cost_c;
ArrayList<Plate> FullMenu = new ArrayList<Plate>();
Plate plate;
if (e == null) {
for (ParseObject plate_o : MenuList) {
Id_c = plate_o.getInt("Id");
Image_c = plate_o.getString("Image");
Name_c = plate_o.getString("Name");
Description_c = plate_o.getString("Description");
Type_c = plate_o.getString("Type");
Cost_c = plate_o.getDouble("Cost");
String text = Name_c;
Toast toast = Toast.makeText(getApplicationContext(), text, duration);
toast.show();
FullMenu.add(Id_c, new Plate(Id_c, Image_c, Name_c, Description_c, Type_c, Cost_c));
plate = FullMenu.get(Id_c);
if (plate.getId() % 5 == 0) {
text = plate.getName();
toast = Toast.makeText(getApplicationContext(), text, duration);
toast.show();
}
}
}
else {
String text = "The get request failed.";
Toast toast = Toast.makeText(getApplicationContext(), text, duration);
toast.show();
}
}
});
And here is my logcat

FullMenu.add(Id_c, new Plate(Id_c, Image_c, Name_c, Description_c, Type_c, Cost_c));
The wrong line. You're trying to add the element to empty ArrayList at certain position. Try to make it like this
FullMenu.add(new Plate(Id_c, Image_c, Name_c, Description_c, Type_c, Cost_c));
If you want to have an access by id as key you should use Map structure.

I cant figure out where I went wrong with my code. Every time I press a button my apps shuts down unless I add a try and catch. As soon as I enter the two numbers and add the sign, the results should print out, but instead the app is just shutting down. Here is my LogCat and code. BTW I'm new to java & android studio, so excuse my mistakes.
public class MainActivity extends AppCompatActivity {
Button btnAdd, btnSubtract,btnMultiply, btnDivide;
TextView textResults, textSigns;
EditText firstnumber, secondnumber;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
firstnumber = (EditText) findViewById(R.id.firstnumber);
secondnumber =(EditText) findViewById(R.id.secondnumber);
textResults = (TextView) findViewById(R.id.results);
textSigns = (TextView) findViewById(R.id.invisible_signs);
btnAdd = (Button) findViewById(R.id.Add);
btnDivide = (Button) findViewById(R.id.divide);
btnMultiply =(Button) findViewById(R.id.Multiply);
btnSubtract =(Button) findViewById(R.id.Subtract);
final String number1 = firstnumber.getText().toString();
final String number2 = secondnumber.getText().toString();
btnDivide.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {int divide = Integer.parseInt(number1) / Integer.parseInt(number2);
textResults.setText(number1 + " / " + number2 );
textResults.setVisibility(View.VISIBLE);
textResults.append("\n" + divide);}
catch(Exception e){
Toast.makeText(getApplicationContext(), "Cannot Divide These Numbers", Toast.LENGTH_SHORT).show();
}
}
});
btnMultiply.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int multiply = Integer.parseInt(number1) * Integer.parseInt(number2);
textResults.setText(number1 + " * " + number2 );
textResults.setVisibility(View.VISIBLE);
textResults.append("\n" + multiply);
}
});
btnAdd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int addition = Integer.parseInt(number1) + Integer.parseInt(number2);
textResults.setText(number1 + " + " + number2 );
textResults.setVisibility(View.VISIBLE);
textResults.append("\n" + addition);
}
});
btnSubtract.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int subtract = Integer.parseInt(number1) - Integer.parseInt(number2);
textResults.setText(number1 + " - " + number2 );
textResults.setVisibility(View.VISIBLE);
textResults.append("\n" + subtract);
}
});
}

Remove these lines
final String number1 = firstnumber.getText().toString();
final String number2 = secondnumber.getText().toString();
And adjust this one
int divide = Integer.parseInt(firstnumber.getText()) / Integer.parseInt(secondnumber.getText());
You don't read the values of the inputs when doing calculations, so the strings will be always empty.
Variables get their values when assigned, the assignment doesn't mean they're bound to the inputs and change their values when the inputs change.
I thought there is two copies of same object.that may be the issue.but I do not know how to solve that.please help me.Thanks in advance

Strange out of memory issue while loading an image to a Bitmap object
I would like to create applications forming charts based on data from parse.com. I have read some examples and tutorials but still have problem with displaying charts. Below is my code:
import android.content.Context;
import android.content.Intent;
import android.graphics.Color;
import android.util.Log;
import com.parse.GetCallback;
import com.parse.ParseException;
import com.parse.ParseObject;
import com.parse.ParseQuery;
import org.achartengine.ChartFactory;
import org.achartengine.GraphicalView;
import org.achartengine.chart.PointStyle;
import org.achartengine.model.XYMultipleSeriesDataset;
import org.achartengine.model.XYSeries;
import org.achartengine.renderer.XYMultipleSeriesRenderer;
import org.achartengine.renderer.XYSeriesRenderer;
import java.util.ArrayList;
public class LineGraph {
public ArrayList<Integer> dataArray;
XYMultipleSeriesDataset dataset;
XYMultipleSeriesRenderer renderer;
public static boolean ClickEnabled = true;
public Intent getIntent(Context context) {
ArrayList<Integer> y = this.dataArray;
XYSeries seriesY = new XYSeries("Y");
for (int i = 0; i < y.size(); i++) {
seriesY.add(i, y.get(i));
}
dataset = new XYMultipleSeriesDataset();
dataset.addSeries(seriesY);
renderer.setPanEnabled(true, false);
renderer.setClickEnabled(ClickEnabled);
renderer.setBackgroundColor(Color.WHITE);
renderer.setApplyBackgroundColor(true);
renderer.setChartTitle("Simple data");
renderer.setAxesColor(Color.BLACK);
XYMultipleSeriesRenderer mRenderer = new XYMultipleSeriesRenderer();
XYSeriesRenderer renderer = new XYSeriesRenderer();
renderer.setColor(Color.RED);
renderer.setPointStyle(PointStyle.DIAMOND);
mRenderer.addSeriesRenderer(renderer);
Intent intent = ChartFactory.getLineChartIntent(context, dataset, mRenderer, "Line Graph Title");
return intent;
}
public void getData() {
ParseQuery<ParseObject> query = ParseQuery.getQuery("Counters_data");
query.getInBackground("lxFzCTeOcl", new GetCallback<ParseObject>() {
public void done(ParseObject parseObject, ParseException e) {
if (e == null) {
String object = parseObject.getString("value");
Integer objectValue = Integer.parseInt(object);
if (dataArray == null) {
dataArray = new ArrayList<Integer>();
dataArray.add(objectValue);
}
} else {
Log.d("score", "Error: " + e.getMessage());
}
}
});
}
}
And there is how I invoke charts:
public void lineGraphHandler(View view) {
LineGraph line = new LineGraph();
line.getData();
Intent lineIntent = line.getIntent(this);
startActivity(lineIntent);
}
And XML part:
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/counters"
android:onClick="lineGraphHandler"
android:text="Charts"

I don't understand where the problem is. My app starts but crashes immediately when I push "chart" button. Is it data type of problem or because I misunderstand something?
Thank you in advance.
I tried like this but still got crash:
public void done(ParseObject parseObject, ParseException e) {
if (e == null) {
String object = parseObject.getString("value");
Integer objectValue = Integer.parseInt(object);
if (dataArray == null) {
dataArray = new ArrayList<Integer>();
dataArray.add(objectValue);
ArrayList<Integer> y = dataArray;
XYSeries seriesY = new XYSeries("Y");
for (int i = 0; i < y.size(); i++) {
seriesY.add(i, y.get(i));
dataset = new XYMultipleSeriesDataset();
dataset.addSeries(seriesY);
}
}
Your getData() retrieves the data asynchronously. dataArray won't be initialized immediately when you call getIntent().
Wait for the async operation to complete before using the data there. For example, call the code requiring that data from the done() callback.
EDIT: For those struggling with this, checkout this link. Follow it carefully, but it does work! The crucial part is using keytool to generate your SHA1 hash against your debug keystore. Also, don't forget to add one for release too!
I've been trying to setup Google Maps Android API v2 and after setting everything up as said I'm getting this runtime exception ClassNotFound:

Your Activity needs to extend FragmentActivity from the support library

Did you run on AVD? if yes try on real devices
I have two String arrays, latitude and longitude
I want to draw polylines on the map, the documentation says, that it's as easy as pie. And it is. If I add polylines manually like this, it works:
PolylineOptions rectOptions = new PolylineOptions()
.add(new LatLng(37.35, -122.0))
.add(new LatLng(37.45, -122.0))
.add(new LatLng(37.45, -122.2))
But the problem starts when I'm trying to loop adding polylines:
rectOptions = new PolylineOptions();
for(int i = 0; i<latitude.length(); i++){
rectOptions.add(new LatLng(Long.getLong(latitude[i]), Long.getLong(longitude[i])));
// Log.d("coordinates", latitude[i]+"|"+longitude[i]);
}
I get a java.lang.NullPointerException And I don't know why. I know the problem is in the rectOptions.add() method, because Log.d("coordinates", latitude[i]+"|"+longitude[i]); works fine in the same loop.
Here's the output of LogCat:
