My code show this error. I didn't use "flutter_secure_storage" dependency but it shows this error. But the app is working well, What is the reason for this and how to fix this also if didn't fix this, the effect of this error?
flutter_secure_storage is a plugin which uses platform specific APIs to interact with the device.
This warning suggests that it is using a deprecated Java API on the Android device. You can't really fix it unless you know Java and are willing to contribute to the plugin. At the same time, you can safely-ish ignore it for now: even deprecated APIs usually last a long time, and it won't affect any functioning until the underlying API is actually removed.
The best thing to do is regularly check for updates to the package, which might fix this warning.
As the error suggests, the package flutter_secure_storage use the file specified in the error, which in turn use or implements a deprecated API.
You might not use that plugin, but you are using some other plugin that use it.
You are not affected by it now because it is just a warning/information.
You could get affected by it when the depreciation goes to be removed instead. But by that time the package will have been updated. So all you have to do is update the package at a later time when said deprecation has been solved.

I have a federated (currently Android + web) plugin. Not my first one, I have a few others to my name :-), still this is the only one that gives problems. How can we force v2 embedding?
Yes, it's using the new API. Yes, MainActivity of the example implements FlutterActivity, nothing else. Yes, the example manifest has the flutterEmbedding metadata. Yes, it also uses ${applicationName} for the application name. Yes, it also has the appropriate launch and normal themes. Yes, the plugin main class implements FlutterPlugin and overrides onAttachedToEngine() and onDetachedFromEngine(). It actually does everything all other plugins do, still the toolchain warns and uses v1 embedding (either from its own example or when referencing the plugin from another app). What actually makes to toolchain decide whether it uses v1 or v2? The flutterEmbedding would be an obvious first answer but it still doesn't work in this case.
And this leads to another, related question. What to do if we have an internal plugin, one inside an app, not to be maintained separately or published for others to use. Such plugins don't need and have an example at all. How can we force v2 in that case? There's no example manifest then...
Addendum: an interesting experiment. If I remove the flutterEmbedding metadata from the manifest, the example won't compile with an error stating that this item is missing -- fair enough. If I place it back, I get no error but I get the warning instead that it uses v1.
I recently upgraded to Flutter 2.0. I have dozens of Flatbuttons that are now deprecated. It's going to take me a few days to fix them all. What are the consequences of shipping an update before then with deprecation warnings? The app still builds and runs fine.
Basically this code will be deleted in future releases of flutter/flutter packages. Most of the time, api's get deprecated when a bug that requires a completely new implementation that will break compatibility or a better implementation that will break compatibility.
Therefore, you can use deprecated code but you should be very careful as they are not maintained and might stop working or deleted in the future. So as long as you are not updating versions you should be fine but it is highly unadvisable.
The problem is that your code will be updated and the flutter will no longer support this widget.
But flutter 2.0 has a tool to help with that. Run the command on your terminal to see what has been depreciated and needs to be updated.
dart fix --dry-run
And execute this other command for fix the depreciated items.
dart fix --apply

While I'm making an Android app, Eclipse will strike out some things. More specifically, Gallery. Here is a screen shot:
When I hover my mouse over the warnings, it says The type Gallery is deprecated. I don't know what Deprecated means, but I do know that it's a Java term. Any help would be appreciated. Thanks!
(From the question before editing: The term is deprecated, not depreciated. It's a common typo, but worth being aware of for searching purposes :)
It's basically a bit like "obsolete" - you're encouraged not to use classes or methods which are deprecated. Typically the documentation will explain why you're not meant to use them, and give you a better alternative. The deprecated version is only present for backward compatibility, usually.
It's worth taking this seriously - a lot of the time if you're using a deprecated API, you're coming at something from a fundamentally flawed approach. Date is the clearest example of this, where the Java 1.0 API was almost entirely deprecated in 1.1, when Calendar was introduced. Using the deprecated methods in Date is a sure way of storing up problems for yourself.
See the Oracle "How and when to deprecate APIs" page for more information.
Deprecated means it used to support older SDK, but not anymore. Thats why you get the warning.
It is just a warning most of the times it works, but you most be careful because it could cause problem with newer versions.
Deprecated isn't a Java term. It is used in many other things but a lot in programming. It simply means that it is no longer supported...normally replaced with something else. The Android Docs will help you adapt it to what you need depending on what you're doing
So I am converting a project from Unity 4.x to 5.x and there are a number of functions that the Unity compiler is warning me that are no longer supported or are obsolete.
My question is do these functions still work? (even though they are marked as obsolete)
I know at some point they need to be updated to the newer API but for the moment I just need to fix the bugs so that the game works. Are these functions still usable? or are they potentially the source of runtime bugs?
Thanks
All obsolete functions has been replaced with new functions. So should take a backup and update your project. Go to Assets->Run API Updater, if your project in not getting updated automatically. Dont worry unity will take care of most of the things.
Yes, it's still work ! They just only warning it.
But i suggest you should change for better result, Unity 5 will update you code from old project, then you should change it following warning, just replace
using "xxxx" instead.
to the current context.
I upgraded our JIRA from version 6 to version 6.1. Suddenly the Activity Streams are always empty. It is very annoying for the users who were very dependent on them. So I need to get the activity streams back.
What I have tried so far:
1. Reindexing
2. Creating a new widget for activity stream
What log can I look into to see what is broken? Do I need to create a new filter or something?
Please do not create activitystream-gadget.xml. Instead, remove the gadgets you have now and install the latest versions of each--including the Activity Stream gadget itself.
Please look at your atlassian-jira.log file.
Mostly this is caused by outdated plugins using deprecated (and now removed) classes. Similar thing happened to me when OSUser class was removed due to deprecation and an older plugin still used it.
If you are not able to view the log, try disabling user installed plugins.
