Is there a way to read the points created when drawing a path? It seems silly to me that a path cannot be readable.Or is it just better to manually write the current finger position to an array?

Do anybody know how to draw path between two points on Map?
I need to draw a line, from one point to other...
I found one link (http://csie-tw.blogspot.com/2009/06/android-driving- direction-route-path.html) about this, but itīs not works well.
I have just started with android ...
I have to develop an android application which should sync with data on webserver..
User adds some data using website, then data should be pulled and synced with data on android device...
I am not sure how to implement this...
Also I have to show map path only between two points (src,dest).. I have googled and it lloks like there is no built-in... only way is to use overlays and draw method.. is my understanding correct?
I am writing a application that needs to draw a "route" comprised of lots of GPS points (long+lat). The points are close together and don't follow roads, simply drawing a line between each point is ideal.
The current implementation I have is very slow as I am looping over all the GPS coordinates and creating a new Point and overlayitem in an itemized overlay. This takes around 20 seconds for it to load all of these points and draw them to the mapview. Is there a way in which I can construct a series of lines or point from the GPS coordinates and draw them onto the mapview?
Example of current implementation:

I am launching an image picker (from the gallery) and my code crashes every single time. I tried to get some help in another post, but people quit responding to the post. Please help. When I do a debug, it tells me this (there are TONS of errors, but these looked the most important - also, I changed the "com.app.name/com.app.name.activity" for privacy reasons):

Here is the code that invokes the activity, follwed by the code that is invoked after the activity has finished:

I have create a zip file on the phone sdk. So i need to create a program to attach that zip file and mail it. For that i need the uri of that file. I used its physical path but it doesn't work. path to the file - sdcard/myfile.zip. i used it in the code in foloowing way
sendIntent.putExtra(Intent.EXTRA_STREAM,Uri.parse("file://sdcard/ myfile.zip"));
when email is sent no attachment can be seen. Is it a problem with a uri. is it a problem with the MIME type
I'd like to use the RandomAccessFile class to access a file that ships with my application. However, that class only accepts a String which is the path to the file. If I place my file somewhere like the assets directory, how do I construct a path to that file? I know I can use the getAssets methods to read up resources, but those only return InputStreams which cannot be seeked.

I'm working on a game which will use projectiles. So I've made a Projectile class and a new instance is created when the user touches the screen:
@Override
public boolean onTouch(View v, MotionEvent e){
float touch_x = e.getX();
float touch_y = e.getY();
new Projectile(touch_x, touch_y);
And the Projectile class:
public class Projectile{
float target_x;
float target_y;
Path line;
public Projectile(float x, float y)
target_x = x;
target_y = y;
line = new Path();
line.moveTo(MyGame.mPlayerXPos, MyGame.mPlayerYPos);
line.lineTo(target_x, target_y);
So this makes a Path with 2 points, the player's position and and touch coords. My question is - How can you access points on this line? For example, if I wanted to get the x,y coords of the Projectile at the half point of the line, or the point the Projectile would be at after 100 ticks (moving at a speed of X pixels/tick)? I also need the Projectile to continue moving after it reaches the final point. Do I need to use line.addPath(line) to keep extending the Path?
I managed to get the Projectiles moving in a straight line, but they're going in strange directions. I had to fudge some code up:
private void moveProjectiles(){
ListIterator<Projectile> it = Registry.proj.listIterator();
while ( it.hasNext() ){
Projectile p = it.next();
p.TimeAlive++;
double dist = p.TimeAlive * p.Speed;
float dx = (float) (Math.cos(p.Angle) * dist);
float dy = (float) (Math.sin(p.Angle) * dist);
p.xPos += dx;
p.yPos += -dy;
The Angle must be the problem. I'm using this method, which works perfectly:
private double getDegreesFromTouchEvent(float x, float y){
double delta_x = x - mCanvasWidth/2;
double delta_y = mCanvasHeight/2 - y;
double radians = Math.atan2(delta_y, delta_x);
return Math.toDegrees(radians);
However, it returns 0-180 for touches above the center of the screen, and 0 to -180 for touches below.

I know the absolute path of an image (say for eg, /sdcard/cats.jpg). Is there any way to the content uri for this file? Actually in my code I download an image and save it at a particular location. In order to set the image in an ImageView currently I open the file using the path, get the bytes and create a bitmap and then set the bitmap in the ImageView. This is a very slow process, instead if I could get the content uri then I could very easily use the method ImageView.setImageUri(uri)

View 1 Replies View RelatedI'm developing an application that is supposed to run on both Android as well as regular Java SE. I have an eclipse project called foobar-core which contains code that is used both by the Android and the SE version. I have another project called foobar-android, which contains all android-specific code. I need to reference some of the foobar-core code in the foobar-android project, so I added foobar-core to foobar-android in Settings -> Java Build path -> Projects -> Required projects on the build path. This works fine, as I can use code from foobare-core in foobar-android now.
Here's the problem: Both foobar-core and foobar-android are independent git repositories, which means they both have a .git subdirectory. Now I get a lot of warnings on the "Console" tab whenever I compile foobar-android. They look like this:
/foobar-core/src/.git/HEAD conflicts with another file already put at .git/HEAD
/foobar-core/src/.git/config conflicts with another file already put at .git/config
/foobar-core/src/.git/description conflicts with another file already put at > .git/description
/foobar-core/src/.git/hooks/applypatch-msg.sample conflicts with another file already > put at .git/hooks/applypatch-msg.sample
How can I tell Eclipse to ignore the .git files when importing sources from the foobar-core project?

View 4 Replies View RelatedIn the app I am making, I would like to take a Base64 image that is received from a server, and save it to a file for displaying later. My question is where should I store this file? It needs to be dynamic, and may be empty when the program launches. I am unsure how exactly the file system on Android works, such as how file paths look.
Ideally I would like to be able to write the data to the image file using a FileOutputStream, and then display that image somehow.
