I'm curious what you mean by "stop the app"? What are you doing to recover, if anything? > - Another set of my checked exceptions were repackaged > JSONExceptions.

I'm curious what would happen in the case that a write of a file in mid-stream failed. Would you end up with a partial JSON object (that would generate a JSONException on the subsequent read)? Or did you catch the IOException, remove the file, and notify the user? Also, would that partially generated file have put your app into a permanently bad state if the user hadn't uninstalled and reinstalled or wiped their sdcard? To dive in further, if this was a simple transient data cache, I wouldn't have any trouble catching relevant exceptions, failing the whole thing, and ignoring the error. On the other hand, if this was an explicit "save" mechanism, I would seriously consider catching any errors, rolling back partial actions, and notifying the user. All meaning is context sensitive. :-) > - Then I had some IOException I repackged.

I'm curious to know what was in the 95% that you got rid of and what you did to deal with what were previously checked exceptions?
