This type of mobile app can be found all over the Internet. The first three hits from here[^] would be a good starting point.
Which part do you need help with SPECIFICALLY?

i'm developing an app with warp function but my code does not working peoperly
i need to move pixels with fingers like liquify in PS
any help would be great.
tnx

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)

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.

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.

I wish this was more common sense.
There are only 10 types of people in the world, those who understand binary and those who don't.

Hi David ,i have finished reading grib2 file,and also have ideas regarding how to draw isobars ,but i want to know which appproach to follow to draw isobar on google map , either use tile overlays or i can use poly lines to draw isobar , or is there any other better way to do this .
And i already break down the job into small parts , like plotting basic map , downloading grib2 file , reading grib2 file , filter pressure data from grib2 file and plotting pressure as isobars on google maps .
So now i am on my last point of plotting isobar on google maps.
If you have some better ideas or findings related to this ,plz share with me .
Thanks ..

Obviously by writing some code. But if you want a more useful answer then please explain your problem in proper detail, including what you mean by "project with multiple table".

Same thing, professionally. I started working on the Android platform about 7 years ago, but it's just a hobby.
