cordova 3.1.0-0.2.0
Droid Razr M
Android 4.1.2
Windows 7
New to PhoneGap/Cordova. Running one of the filesystem demos from http://docs.phonegap.com/en/3.1.0/cordova_file_file.md.html#File. Using "
cordova run android" to compile the code and run it on the phone attached via USB.
Problem #1: When the app first starts I get alert("1") twice and then nothing else.
Problem #2: When I kick of the code via the button onclick I get the following alert pattern: 1, 2, 2, 3, 3, 4, 6, 5, 7, 4, 6, 5, 7. Some of that makes sense based on the code flow but most of them are firing twice.
I'm suspecting problem #2 is being caused by some asynchronous calls hanging out from the first attempt but no matter how long I wait those events don't fire until I kick of the code via the button.
So why is the requestFileSystem call failing even though it is waiting for deviceready and why is the other code getting intermingled?
Any thoughts are appreciated.
