View 2 Replies View RelatedI have to create an app that draws a map reading data from a text file : for example the text file can be like
. index x y orientation
vertex 1 0 0 0
vertex 2 5 0 0.5
vertex 3 10 2 0.3
so i need to do in java something like fscanf does in c (fscanf scans the text file for known formatted data... example, in the file i written i know each line has a string float float float and i need to put them into a specific data structure that can be a list of elements "vertex"
next, when i have all the data, draw a simple image rappresenting the data..
my questions are...
there is a function like fscanf?
and then.. what's better for drawing the 2d map? i have tu use Opengl? At the end i have to draw the image pixel by pixel.. i hope there is something easier then openGL

View 1 Replies View RelatedI am banging my head against the wall trying to create a Bitmap from a Path object (android.graphics.Path). Is there any way to do this? I've browsed through most of the classes now but can't seem to find any way to do it.
Actually, what I have is a Path that consists of many cubic Bezier curves. It is really expensive to draw with canvas.drawPath(). So I figured that I could perhaps "cache" the Bitmap of this Path by converting the Path to a Bitmap once and then just drawing the Bitmap every time instead of calling canvas.drawPath().
Is there any way to create a Bitmap from this Path?
Or is there a smarter way to draw tha Path multiple times without having to recalculate all of the Beziers? For example, if I created a ShapeDrawable from PathShape from the Path, and just draw the ShapeDrawable objects every time, would that be more efficient than drawing the Path every time?

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 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 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.

Is it possible to change the emulator's behavior to create lock files somewhere in /tmp (using some hash of image path as lock file name)? I am OK to try this myself: which repositories from https://android.git.kernel.org/ are necessary to rebuild the emulator alone, and where in the sources is the code responsible for image locks?
I need to run several emulator instances to test my application. When i try to run instances using emulator -data <path> option, the emulator crashes.

The emulator runs normally without "-data" option.
