Registration Error! org.json JSONException Value of type java.lang.String cannot be converted to JSONObject

I am new to android programming. I had a problem with the output of Json on the virtual screen. But when I checked my register.php it looks okay because the result is entered into the database but the output of the screen says a different thing- the error it displayed is
Registration Error! org.json JSONException Value of type
java.lang.String cannot be converted to JSONObject.
What am i doing wrong?
This is my java code
RegisterActivity.java

This is your issue, add the android.permission.ACCESS_BLUETOOTH_SHARE permission to your manifest
I should add that this might not be your only error but it is the one causing this specific crash

How to check if checkbox was checked?

I am creating a quiz app for androids. I have 3 fragments and 3 checkboxes on first two of them. On the last fragment there is a button which when pressed opens an activity called "End". I need that on the "End" activity a result would appear of how many correct answers one have chosen.
Firstly, I've tried to check if it's working with only the first fragment, but I got stuck. The app closes when I press the button.
End.java:
package bandymas.viewpagerexample;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.TextView;
public class End extends ActionBarActivity {
private CheckBox checkBox1, checkBox2, checkBox3;
private Button button;
TextView newresult = (TextView)findViewById(R.id.textView1);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_end);
getSupportActionBar().hide();
addListenerOnButton();
}
private void addListenerOnButton() {
checkBox1 = (CheckBox) findViewById(R.id.checkBox1);
checkBox2 = (CheckBox) findViewById(R.id.checkBox2);
checkBox3 = (CheckBox) findViewById(R.id.checkBox3);
button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
//Run when button is clicked
#Override
public void onClick(View v) {
StringBuffer result = new StringBuffer();
result.append("CheckBox1 : ").append(checkBox1.isChecked());
result.append("\nCheckbox2 : ").append(checkBox2.isChecked());
result.append("\nCheckBox3 :").append(checkBox3.isChecked());
newresult.setText("My Awesome Text");
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_naujas_baigimas, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

im making a simple calories calculator and it gives me that error, i already reviewed the code and searched here for the solution but im not able to see why is not running.
I thought it was because i had not initialized the variable, so i did it and still got the same error, maybe is something with the spinners, im new on using spinners
here is the code:
public class CaloriesCalculator extends ActionBarActivity {

Yout btnCalculate is null, you should initialize before doing the onclickListener:
btnCalculate = (Button)findViewById(R.id.btnCalculate); //your id
Also note that you are initializing the dataAdapter2 but actually you are using dataAdapert, and list2 dont have any elements, because you declare it but u are filling always list1

Android - NullPointerException on ListView adapter when using SimpleDateFormat

I'm having trouble when displaying a custom ListView on a tab (fragment). If I just set the adapter (which is a separate class that extends BaseAdapter) and the fields downloaded from the server, it works just fine. If I set the application to use my custom DateFormat class and format the date taken from the server in dd/MM/aaaa, I get a NullPointerException related to "childMeasure" (full logcat of the error below).

Can someone help me on this? (if additional code samples are needed, I'll be glad to provide)
Thanks in advance!

change
private DateFormat df;
to
private DateFormat df = new SimpleDateFormat("MM-dd kk:mm:ss");

I see private DateFormat df; at the top of your IndicatorsListAdapter-class, but I don't see you intialize it anywhere before you get in the getView line 81:
String stDate = df.getDataAndroid(indicator.getData());
Perhaps change it to:
if(df != null)
String stDate = df.getDataAndroid(indicator.getData());
or simply set your df somewhere before this, like directly at the variable:
private final DateFormat df = new SimpleDateFormat("dd-MM-yyyy");
// replace dd-MM-yyyy with your desired Date format
