 Hi there,

 I see at least two issues:
 1: your button click listener takes lat/long from the EditText's, then
 effectively starts the Maps app (Intent url is geo:lat,long).
 2: The GeoPoint constructor takes coordinates that are scaled by
 100, i.e. 45.7 N would be 4570. (see e.g.
 http://developer.android.com/resources/tutorials/views/hello-mapview.html)

 OK. So user entered location as lat and lon. Why can't you plot it? What's

Hey TreKing,

If you dont mind, just refer this code.
You exactly got what is going on here. I am new in Android so I dont know
what is stack trace and log? How to check stack trace?

So here is my code.

public class ShowLocation extends MapActivity {

 2) Are you trying to send an intent to the Maps or Browser app, of handle
 the location display yourself? In one place the code has:

 yet in another line, the code goes:

Re: [android-developers] Find the location in Android Map

[Dhrumil Shah]

I thought you want to to display a mark on a map from the latitude and
longitude a user entered in two text fields. But I don't understand if you
want to display that on a MapActivity in your app or in another app.
- I want to display that  on a MapActivity in my app. Not in another
activity.


One thing that may help is if you try to display a mark on a map foir a
given latitude and longitude instead of from a user's input. Have you been
able to do that successfully?
- Yes, I tried with that also. Firstly, I entered hardcore values in the app
of latitude and longitude. Its working.
But everytime we have to change it for different locations. Thats why I put
EditText and button so user can enter its own latitude and longitude.

   You should not change things you do not understand in hope it will
 work
   even you do not know why. There's clear error message quoted above
   and there's manual you shall read to get what value is valid there:

 Hi,

 I have two activities.A and B.
 A starts B.Both are running in the screen and both are visible. Say

 On a special key press, I want to bring the A to the front and make it

 The problem I am facing is when the special key is pressed, another
 instance of A is launched and the new instance is brought to the
 front.

 But I want the original A to come to the front. I want to make this
 change in the framework layer rather than application specific by
 using the singleInstance theme in the launchMode in AndroidManifest
 file.

 Please help me in this regard as this is really urgent for me.
 Any inputs will be really valuable for me.

 Thanks in advance.

[android-developers] Upgrade my Game Application

[dhrumil]

Hello 2all,

I have developed one simple game application.
In that, the box is moving in all four directions. Now I want to
upgrade my game. So for that I just add one ball image on this
application. This ball image is bouncing all over the android screen.
I tried a lot but not able to upgrade my game. The only box is visible
on the screen and the ball image is not visible.

I want to display both of them on the screen.
How to do this?
Any suggestions.
Please anyone knows give me a reply.

Re: [android-developers] Upgrade my Game Application

[Dhrumil Shah]

* *void* onDraw(Canvas canvas){

*if*(myPoint.x= *this*.getWidth() - myPosition.getBounds().width()){

*this*.myXDirection = HorizontalDirection.*LEFT*;

}

*else* *if*(myPoint.x = 0){

*this*.myXDirection = HorizontalDirection.*RIGHT*;

}

*if*(myPoint.y= *this*.getHeight() - myPosition.getBounds().height()){

*this*.myYDirection = VerticalDirection.*UP*;

}

*else* *if*(myPoint.y=0){

*this*.myYDirection = VerticalDirection.*DOWN*;

}

*if*(*this*.myXDirection == HorizontalDirection.*RIGHT*){

*this*.myPoint.x += 10;

}

*else*{

*this*.myPoint.x -= 10;

}

*if*(*this*.myYDirection == VerticalDirection.*DOWN*){

*this*.myPoint.y += 10;

}

*else*{

*this*.myPoint.y -= 10;

}

*this*.myPosition.setBounds(*this*.myPoint.x, *this*.myPoint.y, *this*.
myPoint.x + 50, *this*.myPoint.y + 50);

*this*.myPosition.draw(canvas);

}

}

This is my code. In that game, the box is moving left, right , top and down.
In the same, I used one image of ball, which is bouncing. But my problem is
the bouncing ball is not visible.

How to solve it? Please suggest me.

Re: [android-developers] Re: How to use D-Pad control in Android

[Dhrumil Shah]

Hey Avigadl,

If I change the values of the each direction like DIRECTION_TOP = 0,
DIRECTION_DOWN = 1, DIRECTION_RIGHT = 2, DIRECTION_LEFT = 3; it is working?

I changed that but unfortunetly its not working.
Any other Solution?

 Several suggestions:
 1. Note that all the directions has value 0, this might be a poblem
 wen you want to distinguish between directions. You have to set  a
 unique value to eac direction.
 2. We suggest to use switch case statement instead of if else if.

 Hope this helps.
