It will take a lot of code. What exactly is your question?

This type of mobile app can be found all over the Internet. The first three hits from here[^] would be a good starting point.

And we're supposed to be able to decipher this?
Exactly what does not work?
What is it supposed to do? What is it doing instead?
What did you find when you stepped through the code using the debugger?
Have you narrowed the code down to just a few lines of code rather than several dozen, most of which is irrelevant?

i want something like this :
[^]
my code just makes some distortion in the thoched point and minimizes the area.
unfortunately i did not find any primary line in the code they are very hard to understand 
i thought this feature is already known to everyone 
thank you for reply![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Um, it's your code, isn't it?

you sound like a doctor 
this code is everywhere i just change it a little bit for fit inside a class
i managed to do some changes with changing
final float K = 10000;
float[] src = mOrig;
float[] dst = mVerts;
for (int i = 0; i < COUNT * 2; i += 2) {
float x = src[i + 0];
float y = src[i + 1];
float dx = cx - x;
float dy = cy - y;
float dd = (dx * dx + dy * dy) /2;
float d = (float) Math.pow(dd, 2);
float pull = K / (dd + 0.000001f);
i bold them!
it still does wrong action but much better than previous one
do you have any solution?

To what? You've shown a few random pieces of code, but haven't explained what they are doing nor what they are supposed to do.

Funny how the first three results from that search are from the OP!

Which part exactly are you having trouble with? Are you able to create an activity that displays a (Google) map? If you can't get this far, everything else is pointless. Are you able to add a layer to that map with a point/pin on it? Focus on adding one before bothering with dozens or hundreds. Break this project down into 4-5 smaller projects and handle those incrementally rather than trying to solve the larger project all at once.
