View 4 RepliesI'm designing a custom view which is an X/Y Plot. It's a moving graph that scrolls to the left with time and new Y values are continuously coming in at 10 per second.
I've been able to make it work with an array of integers where the array index is the X value and the integer value is the Y value, but this seems horribly inefficient (Because every time it comes time to re-paint, I have to loop 800+ times to paint the graph). Then we do it all again 10 times a second. yuck.
Can anybody think of a paintable object that I can draw points to and perform some kind of scroll transformation and then just draw the new points each time, rather than the whole canvas?
Any other ideas out there?

View 2 Replies View RelatedI'm working on an Android application that stores data in a SQLite database. My question is, where does this database file get stored on the filesystem when you're using an emulator?
I have seen that it's stored in /data/data/package_name/databases
But I need to know where on my local machine's hard drive that actually maps to. The database persists on multiple runs of the emulator, even after having shut down the machine, so it can't just reside in RAM...
I need to store an retrieve a vector of an unknown number of objects in an android sqlite database. Essentially, the setup is this: I am developing a task management app, where the user can add as many notes as they like to their tasks. My current setup uses one database, with one row per task. This presents a problem when I need to associate multiple notes and their associated information with one task. I can see two approaches: try to store an array of notes or a vector or something as a BLOB in the task's row, or have another notes database in which each row contains a note and it's info, as well the id of the task which the note belongs to. This seems a little easier to implement, as all I would have to do to retrieve the data would be to get a cursor of all notes matching a particular id and then iterate through that to display them to the user. However, it seems a little inefficient to have a whole new database just for notes, and it makes syncing and deleting notes a little more difficult as well. What do you think? Is it worth it to have a separate notes database? Should I use a BLOB or go for the separate database? If a BLOB, are there any good tutorials out there for storing and retrieving objects as BLOBs?

Is it possible? If it is, how to proceed? On the Blackberry platform, I am able to store objects directly in persistent objects. Is it possible to do this with SQLite and Android?

At some point, usually after completing the data collection rounds, the local sqlite db is to be synchronized to a remote sybase db on the server.Any suggestions as to how this could be achieved or engineered as a solution? Or even better, are there alternatives to synchronizing data in such an application?

View 4 Replies View RelatedI am new application development. I am using Eclipse for making applications. When trying to create new project using Eclipse It is not creating simple res/drawable/ instead its creating three drawable folder. i.e. 1] drawable-hdpi 2] drawable-ldpi, 3]drawable-mdpi What is this all three for? General scenario as per Google it needs res/drawable/ to save icon image. Now on Eclise where to save icons? On all folder or?
View 4 Replies View RelatedAccording to official documentation Google says that "Once you've defined your Drawable in XML, save the file in the res/drawable/ directory of your project." is the way to add a XML drawable to the project. But when I created the project ADT created 3 different drawable folders for mdpi, hdpi, and ldpi. So when I wanted to create my XML drawable, I right click on my drawable-hdpi folder and select "Add new Android XML file", and there I have to select what kind of XML file I want to create, but there isn't "drawable" to select. If I create new text file and save it as button_drawable.xml Eclipse says that there is an Error in the file and that It can't build my project.
