Problem
The largest integer that can be saved without causing an exception is 2147483647, which is (2^31)-1.
Note that large numbers can be successfully saved on:
* iOS (according to reporter)
* Android + Titanium 1.8.0.1 + v8
* Android + Titanium 1.8.0.1 + rhino
Test case
Ti.App.Properties.setInt("lowInt", 2147483647);
Ti.API.info("****** lowInt Saved ******");
Ti.App.Properties.setInt("highInt", 2147483648);
Ti.API.info("****** highInt Saved ******");
Ti.App.Properties.setInt("veryHighInt", 1325269931753);
Ti.API.info("****** veryHighInt Saved ******");

Workaround
Use
Ti.App.Properties.\[g|s\]etDouble():
Ti.App.Properties.setDouble("veryHighInt", 1325269931753);
Ti.API.info("****** veryHighInt Saved ******");
Ti.App.Properties.setDouble("veryHighIntPlusOneThousand", Ti.App.Properties.getDouble("veryHighInt") + 1000);
Ti.API.info("****** veryHighIntPlusOneThousand Saved ******");
Ti.API.info("----> veryHighIntPlusOneThousand = " + Ti.App.Properties.getDouble("veryHighIntPlusOneThousand"));

A possible workaround is to divide getTime() by 1000 to get the number of seconds, and then use parseInt() to remove the floating point portion. Then you lose millisecond precision, though.
Ti.App.Properties.setInt("my_key_here", parseInt(instance_of_date.getTime() / 1000));For the reasons explained in TC-524, would you please edit the ticket to includes a test case that produces the included error? Thanks
Keith Did you seriously test this issue on all those devices listed in the environment field, or are you simply listing all the devices you have available? Please only include the devices that you have physically tested. Also, if you have tested it in an emulator, you could include details of that. Thanks
Keith Would you please provide the information I've requested, so I may escalate this ticket? Thanks
I have personally tested it on a Samsung Infuse 4G on AT&T running Gingerbread and my QA team tested it on whatever devices they tested it on (which is probably the aforementioned list but may not be the entire list, since the code failed miserably, they may not have tested it everywhere). "org.mozilla.javascript.EvaluatorException: Cannot convert 1325269931753 to java.lang.Integer" does not strike me as a device-specific problem however.
The use case is invalid. Blain Harmon's response below. However, am going to raise a apidoc ticket as this should be documented. I do believe that the difference is that iOS is simply letting the value overflow, so that the value stored with setInt would be some truncated, rolled over value. The reason I say that is that the data type used during setInt is indeed a 32 bit signed integer, and Apple's iOS docs say nothing of exceptions (The underlying method that causes the conversion is [NSNumber intValue]). Either way, An Int is a specific data type, of a 32 bit signed integer. HOWEVER, I think the issue here is one of documentation, to specify that int is the aforementioned specific data type. If you wish to store a larger value, setDouble exists for that very reason.
Closing ticket as invalid.
