I'm developing with SDK 1.6.2.
My app uses the camera to capture and save an image to Titanium.Filesystem.applicationDataDirectory.
A tap of the app is supposed to display all stored images (details [path] stored in database) tiled across the screen.
Saving the image:
var image = event.media // from camera success
var filename = new Date().getTime() + "-ea.jpg";
bgImage = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory, filename);
bgImage.write(image);
Storing to database:
var db = Titanium.Database.open('photoDB');
try{
db.execute('INSERT INTO stored (image) VALUES (?)', bgImage.nativePath);
} catch(e) {
alert(e.message);
}
db.close();
Showing the Images:
imageArray = [];
images = [];
var db = Titanium.Database.open('photoDB');
var dbrows = db.execute('select id, date, image from stored order by date asc');
while (dbrows.isValidRow()) {
imageArray.push({
image:dbrows.fieldByName('image')
});
dbrows.next();
}
dbrows.close();
// loop thru and display images
for (var i = 0; i < imageArray.length; i++){
var pushleft = (i % 4) * 75; // tile from left
var pushtop = Math.floor(i/4) * 96; // determine how far from top
var file = Titanium.Filesystem.getFile(imageArray[i].image);
images[i] = Ti.UI.createImageView({
image: imageArray[i].image, // path to image at applicationDataDirectory
width: 75,
height: 96,
left: pushleft + 5, // logic for positioning
top: pushtop + 5, // logic for positioning
store_id: imageArray[i].id
});
win.add(images[i]);
}
Unfortunately, while the tiles work the images are just showing the image placeholder, not the stored image.
I have phonedisk, so after building the app for my device I can view the application directory and the images are being stored.
What am I missing?
Figured it out, thanks everyone for the help ;) < sarcasm (It's only been a day, I hold no grudges)
Here's what was wrong in case anybody else has a similar issue.
// Create a file name
var filename = new Date().getTime() + "-ea.jpg";
// Create the file in the application directory
bgImage = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory, filename);
// Write the image to the new file (image created from camera)
bgImage.write(image);
When I was storing the image location in the database I was storing the full path bgImage.nativePath
. However, when I updated and rebuild the app the apps applicationDataDirectory changed, so the stored path was invalid.
So now I just store var filename
in the database and when I display it like this:
images[i] = Ti.UI.createImageView({
image: Titanium.Filesystem.applicationDataDirectory + Ti.Filesystem.separator + imageArray[i].image, // path to image at applicationDataDirectory
width: 75,
height: 96,
left: pushleft + 5, // logic for positioning
top: pushtop + 5, // logic for positioning
store_id: imageArray[i].id
});
Now, even with updates, it always points to the proper applicationDataDirectory
