Android :: Path To Array / Read Points On Path?

Jul 5, 2010

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?

Android :: Draw Path On MapView From Large Amount Of Longitude/latitude Points

Aug 2, 2010

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:

Android :: Get File Path With URI

Apr 1, 2009

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):

04-01 14:09:30.254: WARN/dalvikvm(719): threadid=3: thread exiting with uncaught exception (group=0x4000fe68) 04-01 14:09:30.254: ERROR/AndroidRuntime(719): Uncaught handler: thread main exiting due to uncaught exception 04-01 14:09:30.274: ERROR/AndroidRuntime(719): java.lang.RuntimeException: Failure delivering result ResultInfo {who=null, request=1, result=-1, data=Intent { data=content://media/ external/images/media/7 }} to activity {com.app.name/ com.app.name.activity}: android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 1 04-01 14:09:30.274: ERROR/AndroidRuntime(719): Caused by: android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 1

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

public void takePic() { Intent photoPickerIntent = new Intent(Intent.ACTION_PICK); photoPickerIntent.setType("image/*"); startActivityForResult(photoPickerIntent, 1);

Android :: How To Get A Path To Resources

Sep 10, 2010

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.

Android :: Following Straight Line (via Path)?

Nov 4, 2010

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.

Android :: Get Content Uri From File Path?

Jun 9, 2010

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)

Android :: Adding One Project To Another Build Path?

Jul 4, 2010

I'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?

Android :: File Path For Base64 Image

Jul 19, 2010

In 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.
