in my OnCreate:
Intent thisIntent = getIntent();
date = thisIntent.getExtras().getString("date");
and my line 111:
labelDate.setText(date);

You are accessing a null variable in line 111 in file MainActivity2.java .
Check what you wrote there.
From your code it seems that either labelDate is null or date is null.
Verify you have values in them , you can also debug.
In general, it seems best if you do some tutorial from developer.android.com .

Check out with this code:
Bundle bundle=getIntent().getExtras();
if(bundle!=null){
String date=bundle.getString("date");
labelDate.setText(date);
}
hope this will help you.

your date object is null in line 111, b'coz your intent may not have key named as date or the value will be null.
To prevent from this exception:
make sure that labelDate is not null
make sure that date object is not null before assign to setText();
ex:
if (date != null)
labelDate.setText(date);

You didn't give us enough information. NullPointerException can be thrown for many reasons.That error means that an application attempts to use an object reference that has the null value.

Null Pointer Exception in First Android App

I am trying to write my first Android app, and I'm having trouble. I wrote a simple Java program to find the factors of a number provided by the user, and I'd like to port it over to Java. I have an XML file for the interface, which seemed to run OK until I added the first Java class. Now it won't run, and log.cat says that there's a null pointer exception. So far, I only have stubs, but it seems like it should run OK with what I've done to this point. I'm including the log.cat text, but I'm too new it this to make much sense out of it.
There may be more than one problem. After adding the Java file I began to get run-time errors right away, but I don't think they were null pointer exceptions. I think that started when I made changes to fix what was already causing problems.
Any help is appreciated.
Here is the Java file:
import android.app.Activity; <br>
import android.os.Bundle; <br>
import android.widget.Button; <br>
import android.widget.EditText; <br>
import android.widget.TextView; <br>
public class AndroidFactoringActivity extends Activity {
// Instance Variables
EditText userNumber;
Button factorButton;
TextView resultsField;
int factorResults;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
factorButton = (Button) findViewById(R.id.factorButton);
userNumber = (EditText) findViewById(R.id.userNumber);
factorResults = 1;
resultsField.setText(String.valueOf(factorResults));
}
}
Here is main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

android:layout_width="fill_parent"

<requestFocus />
</EditText>
<Button

resultsField.setText(String.valueOf(factorResults));
resultsField is null and you are trying to set value on null.
resultsField= (TextView ) findViewById(R.id.userNumber);
Get textview instance before setting value, otherwise resultsField will be null and all operations on null reference results in NullPointerException.

You got a null pointer because you didnt intialise the variable resultsField (you just declared it) .
As you used
userNumber = (EditText) findViewById(R.id.userNumber);
you must even initialise the reference resultsField.
This can be done using
resultsField= (TextView ) findViewById(R.id.resultsField);
in the onCreate() after the statement setContentView()

You need to initialize the userNumer and resultsFiled as follows
userNumber = (EditText) findViewById(R.id.userNumber);
resultsField= (TextView ) findViewById(R.id.resultsField);

Either:
you are calling findViewById() on the wrong thing, and therefore are getting an ImageView when you are expecting something else
your R class is out of sync with the rest of your code, which can be fixed by cleaning your project (Project > Clean from the Eclipse main menu, or ant clean from the command line)

NumberFormatException in GPS processing

I am having a weird problem.
I am developing a program to log GPS and sensor readings periodically. My friend runs the code on his machine using Eclipse Galileo 3.6 and it works perfectly fine for her.
When I run the code on my machine which has Eclipse Galileo 3.5.2 it shows service stopped unexpectedly.
We have the same JDK version. I am not able to figure out what may be the exact problem.
Please let me know what else information I need to give in order to fix the problem.

The pertinent code for line 88 with parsing going on:
public void startService(){
//startService(new Intent(MainScreen.this,SensorReadings.class));
Intent intent = new Intent(MainScreen.this, SensorReadings.class);
**intent.putExtra("lp", Integer.parseInt(""+longPeriod.getText()));// LINE 88**
intent.putExtra("gp", Integer.parseInt(""+gpsPeriod.getText()));
intent.putExtra("sp", Integer.parseInt(""+snrPeriod.getText()));
//startActivity(intent);
startService(intent);
}
Thanks.

Perhaps at line 88 in MainScreen.java, your startService method is calling Integer.parseInt with an empty string?
Can you show us the pertinent code?

I don't get why you are putting "".
So to be sure this is not the problem try either this:
intent.putExtra("lp", Integer.parseInt(longPeriod.getText()));
intent.putExtra("gp", Integer.parseInt(gpsPeriod.getText()));
intent.putExtra("sp", Integer.parseInt(snrPeriod.getText()));
or
String lp = longPeriod.getText();
String gp = gpsPeriod.getText();
String sp = snrPeriod.getText();
intent.putExtra("lp", Integer.parseInt(lp));
intent.putExtra("gp", Integer.parseInt(gp));
intent.putExtra("sp", Integer.parseInt(sp));
The second way is better for debugging... so you can see what is actually happening.

I fixed it... I kept on trying and, at the end, it turns out that I cannot use an integer-array as the entryValues Source. I just changed that integer-array to a string-array and got it working.
If there's a way to use integer-array as the source for entryValues please comment.

I've been searching for a similar solution to what you are looking for, agreeing that you should be able to use an Integer array to read from and store an integer result.
A solution to this problem I found was at http://kvance.livejournal.com/1039349.html, which I found to be useful.
It doesn't quite solve the problem the way I was thinking or that way I think you want it to, instead you still specify your initial / selection values with a String array although when the ListPreference saves it back to the SharedPreferences it saves as an Integer instead of a String (doing the conversion when the user selects it), removing the need to have to convert it possibly many times throughout your application when accessing the preference value.

Crash in application. RuntimeException: Unable to start activity [closed] - android

Check out with this code: Bundle bundle=getIntent().getExtras(); if(bundle!=null){ String date=bundle.getString("date"); labelDate.setText(date); } hope this will help you.

your date object is null in line 111, b'coz your intent may not have key named as date or the value will be null. To prevent from this exception: make sure that labelDate is not null make sure that date object is not null before assign to setText(); ex: if (date != null) labelDate.setText(date);
