You must call Parse.initialize(context, oauthKey, oauthSecret) before using the Parse library.

I have called a function returnCurrentNameById() by passing the id of the particular row. But it gives an error.
String[] s1;
public String[] returnCurrentNameById(int k) throws SQLException{
String[] columns = new String[]{ KEY_ID1, KEY_NAME, Key_DOB, KEY_AGE, KEY_PHONE_NO, Key_EXPERIENCE, KEY_EMAIL, KEY_STATUS, KEY_STATUS};
SQLiteDatabase db3 = this.getReadableDatabase();
Cursor c = db3.query(DATA_BASE_TABLE_NAME1, columns, KEY_ID1 + "=" + k, null, null, null, null);
if (c != null){
c.moveToFirst();
for(int i = 0; i<=8; i++){
s1[i] = c.getString(i);
}
return s1;
}
return null;
}

You have not initialized your s1 array.
Use
s1 = new String[9];
to allocate an array of 9 elements.
Also check the return value of moveToFirst() so you don't get an exception in case the query returns no rows.
Replace
Cursor c = db3.query(DATA_BASE_TABLE_NAME1, columns, KEY_ID1 + "=" + k, null, null, null, null);
with
Cursor c = db3.query(DATA_BASE_TABLE_NAME1, columns, KEY_ID1 + " = ?", new String[]{String.valueOf(k)}, null, null, null);
I have a DialogFragment which is supposed to display a VideoView and some TextViews. However, VideoView is null, along with other controls, even though the layout has been inflated.
Here is the code where I retrieve the pointer to various controls:
#Override
public void onViewCreated (View view, Bundle savedInstanceState) {
controls = new MediaController(getActivity());
title = (TextView) view.findViewById(R.id.title);
date = (TextView) view.findViewById(R.id.date);
description = (TextView) view.findViewById(R.id.description);
video = (VideoView) view.findViewById(R.id.video);
controls.setAnchorView(video);
video.setMediaController(controls);
}
But, debugger says otherwise:
Why are they null?
I have inflated the layout in create view where they are defined.

you need to some change
put your code
title = (TextView) view.findViewById(R.id.title);
date = (TextView) view.findViewById(R.id.date);
description = (TextView) view.findViewById(R.id.description);
video = (VideoView) view.findViewById(R.id.video);
from onViewCreated() to onCreateView() then bind data on onViewCreated() method.
Here is the code:
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = new ExpenseIcon(context);
((ExpenseIcon) convertView)
.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
System.out.println("Expense Icon Clicked");
Intent a = new Intent(context, ExpenseInput.class);
a.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP & Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(a);
}
});
}
if (image == null)
image = BitmapFactory.decodeResource(context.getResources(), R.drawable.dollar);
((ExpenseIcon)convertView).setImageBitmap(image);
return convertView;
}
When I click on the ExpenseIcon button I get an exception thrown at the line context.startActivity(a):

I'm unsure why and not sure how to fix...
Try this,
Intent a = new Intent(context, ExpenseInput.class);
a.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(a);
i am using the services of parse.com, android guide:
https://www.parse.com/docs/android_guide
and it didnt work for me (i get a message: app must be closed...)
here is my code:
gameScore = new ParseObject("GameScore");
gameScore.put("score", 1337);
gameScore.put("playerName", "Sean Plott");
gameScore.put("cheatMode", false);
try {
gameScore.save();
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
gameScore.saveInBackground(new SaveCallback() {
public void done(ParseException e) {
// Access the object id here
objectId= gameScore.getObjectId();
}
});
ParseQuery query = new ParseQuery("GameScore");
query.getInBackground(objectId, new GetCallback() {
#Override
public void done(ParseObject parseObject, ParseException arg1) {
// TODO Auto-generated method stub
int score= parseObject.getInt("score");
Integer i =new Integer(score);
t1.setText(i.toString());
}
});

Also, when i am on debugging mode, i see that the objectId is null ,although i can see in the server that the object uploded succesfully with problem and it has a valid objectId.
Also, when i look in the gameScore object in eclipse i can see that it has the same objectId as in the server , however again it return me null in the objectId
thanks
So what is happening is you are executing saveInBackground which starts on a new thread. You will then immediately call query.getInBackground with a null objectId. You need to wait and call query.getInBackground AFTER the done call in gameScore.saveInBackground.
I would recommend moving the second call to the done function call in the gamerScore.saveInBackground execution above. Also you must consider that the save may fail so you will want to catch the exception as follows:
public void done(List<ParseObject> items, ParseException e) {
if (e == null) {
//execute query here
} else {
//handle exception here
}
}
Here is the code I use to bring up the activity:
startActivity(new Intent(getApplicationContext(), Giveaway.class));
Here is the Activity that I am bringing up:

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.giveaway);
settings = getSharedPreferences("firsttime", 0);
LinearLayout facebook = (LinearLayout)findViewById(R.id.facebooklayout);
Button later = (Button)findViewById(R.id.later);
Button dontshowagain = (Button)findViewById(R.id.dontshowagain);
facebook.setOnClickListener(this);
later.setOnClickListener(this);
dontshowagain.setOnClickListener(this);
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.facebooklayout:
Uri localuri = Uri.parse("http://www.facebook.com/pages/Bright-Design/366832480049386");
startActivity(new Intent("android.intent.action.VIEW", localuri));
break;
case R.id.later:
finish();
break;
case R.id.dontshowagain:
finish();
prefEditor = settings.edit();
prefEditor.putBoolean("showgiveaway", false);
prefEditor.commit();
break;
}
}

You need to post your layout code, but what is most likely happening is that one of these three lines is returning a null value:
LinearLayout facebook = (LinearLayout)findViewById(R.id.facebooklayout);
Button later = (Button)findViewById(R.id.later);
Button dontshowagain = (Button)findViewById(R.id.dontshowagain);
In the debugger step through those lines and if one is null, there is your problem because as soon as you try to set the on click listener it is going to fail.

at com.brightdesign.blackops2.Giveaway.onCreate(Giveaway.java:29)
Tells us that there is a NullPointerException in Giveaway.onCreate(), specifically Giveaway.java line 29. Odds are facebook, later, and/or dontshowagain is really null. Do you have all three of these defined in giveaway.xml?
Try this...
1.
Intent i = new Intent(Your_Activity.this, Another_Activity.class);
startActivity(i);
2. This below lines points to the class and the lines which are null.
Class:
com.brightdesign.blackops2/com.brightdesign.blackops2.Giveaway}: java.lang.NullPointerException
Lines:
Please check the below four lines, i think you are getting null value here.
Uri localuri = Uri.parse("http://www.facebook.com/pages/Bright-Design/366832480049386");
LinearLayout facebook = (LinearLayout)findViewById(R.id.facebooklayout);
Button later = (Button)findViewById(R.id.later);
Button dontshowagain = (Button)findViewById(R.id.dontshowagain);
