Saving Photo to Image app

[Chris Tracey]

Hi All

Firstly I'm quite an inexperienced user, so apologies if this is a basic query.

I'm writing a v simple app which lets a user take a picture with their android and save some meta information about the pixture.

The first layout uses spech-rec to capture the meta-text. You then click to a second layout to check the text . Then click to a third which takes the photo and holds it in the image control. Most of the code is customised from the examples in the Droidscript help.

The speech rec layout seems to work ok. I can then click through to the second layout ok , and then onto the third. I can take take a picture, but when I click the tick to save it on the camera app, it returns to the first layout rather than the thrid (i.e the one which has the image placeholder). So I don't get to see the picture which I've just taken. I can get the photo example from the Droidscript to help though, and my app uses pretty much the same code.

Any ideas what I'm doing wrong? Does the app run the OnStart function again when it closes down the camera app? If that it is the problem, then are there any pointers for getting around it.

Code is below

Thank you in advance!

HI,

If you touch the "bug" icon instead of the run icon (triangle) you should see the debug on top of your screen to see what's happening 

(or if using the WiFi IDE, see the debug tab).

You can also add JavaScript alerts to your code.
