If the exception is something that you cannot recover from, and the user needs to know about then you could catch the exception and show it in an AlertDialog: try { // do something } catch (SomeImportantException e) { AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage("User friendly text explaining what went wrong."); AlertDialog alert = builder.create(); alert.show(); } For more info on the dialog, see creating dialogs. Alternatively, if the exception is something that you can deal with, you can just log information about the exception and move on. try { // do something } catch (SomeLessImportantException e) { Log.d(tag, "Failed to do something: " + e.getMessage()); } share|improve this answer edited Apr 23 '14 at 14:47 Tim S.

The type of errors I'm concerned with are limited functionality due to no Internet connectivity, etc. I thought to create a dialog that the user can close (and then be provided with a cached version of the app), but am now thinking it might make more sense to java error handling pop up a notification at the top of the app (Android UI Docs). I feel like this might be more in line with Android style guides, but at the same time I'm not sure that it's appropriate. If anyone knows of any articles, especially from Android, that would be greatly appreciated. android errors share|improve this question asked Nov 6 '12 at 18:59 Simon 501139 IIRC Android's guidelines recommend against persistent notifications. Is this an error that affects an active app/process or something where the user might not know if anything went wrong? –Ben Brocka♦ Nov 6 '12 at 19:05 The activity would actually impede the user, (for example:) it's an app that relies on internet connectivity, but the plan is to have there be limited functionality still available. So these aren't errors that relate to crashes, or things that don't work, but more related to limited functionality, or some missing information that is wrong on the user's end. –Simon Nov 6 '12 at 19:08 Don't cause them :-) –Danny Varod Nov 9 '14 at 20:34 @DannyVarod Wouldn't that be an ideal world –Simon Nov 11 '14 at 1:55 Practically, a general guideline (not Android specific) is if you can try to overcome the error (e.g. retry) do so, if not (or if that fa
with Raygun Callum GavinJune 26, 2015Android, Provider Updates, Tech StuffLeave a Comment Java and Android offer a rich and powerful set of tools for creating compelling mobile apps. The development of those apps can be quite productive these days, with modern tools like Android Studio, Gradle and Git. When it comes to releasing your app onto Google Play Store, however, the software development lifecycle dictates the job is only beginning. The maintenance phase is the most critical, and has the highest associated costs for fixing bugs that aren't identified earlier during implementation or testing. Fortunately, error tracking tools like Raygun can help catch runtime errors that slip through the QA process, and alert you when your app crashes for your users. Often, they'll be quick to delete it from their devices, but you can save a customer and potentially negative reviews by informing them when it's fixed, without them having to lift a finger. It doesn't take much to amaze users with great support, who will then recommend your app to their friends and family without hesitation. Much better than a bad review for a buggy app! There are many common Android exceptions that Raygun and its open-source provider Raygun4Android can alert you to when they occur on your user's devices, and what follows is a list of the most critical. OutOfMemoryError This error can happen at runtime when you ask Dalvik to allocate a large amount of memory on the heap - for instance when trying to add a large bitmap into a container like an ImageView. If you're pulling the bitmap from a remote endpoint you need to be sure you're guarding against files, as these might cause the app to crash if this exception isn't handled. There are configuration flags available such as android:largeHeap in the AndroidManifest if you do need to allocated large objects. Application Not Responding This very common dialog is caused by the system killing unresponsive applications that have hung on a long-running operation. This could occur when a network I/O connection to a third-party is unresponsive, perhaps due to unreliable connectivity, and many other such conditions. It is critical you keep the UI thread buttery smoo
