What do the following icons mean?
I saw symbol reference but I didn't find what I want.

This information can be found in IntelliJ IDEA documentation.

You can distinguish above two icons now.

Quick Helper Annotaion in Java Editor

I'm trying to develop a eclipse plugin, which displays a Quick help annotation in the Java Editor.
The Quick Help icon should appear at every place, a type statement is missing in the Java-Code.
I'm a total noob in Eclipse plugin development. I read a few things about it and understand the idea with Extension points but I don't get how to add a annotation in the Eclipse Java editor.
Are there any examples or tutorials available for this problem/topic?
I don't know how to start and appreciate any help or hints.
I finally made it by placing a Marker and specifying a markerResolution for him.

Intellij idea deprecated no strikeout/strikethrough

I'm using IntelliJ IDEA v12. When I import a project, there’s a strikeout/strikethrough line on the method which has the annotation #Deprecated, but I used alt+enter to disable it. So, how can I reactivate this feature? I want to display that strikethrough, thanks!
Open Settings -> Type Inspections to go to inspection settings -> Type Deprecated to find out all deprecated related inspection settings -> Check Deprecated API usage.
IntelliJ had a bug in 2018.3, 2018.2.2 (182.4129.33). It was fixed in builds 191.65, 183.3691.
Setting -Dide.text.effect.new.metrics=false in the .vmoptions fixes the problem.
In addition to Ionghua's answer .....
If you find that IntelliJ is still not striking out deprecated methods, even though you have enabled the inspection as above, check to make sure that your code is not ignoring deprecation warnings with #SuppressWarnings("deprecation").
In addition to longhua's answer... and vegemite4me...
Another possible source for this problem might be custom color themes.
If you are using a custom theme, make sure that it contains strikethrough. I was using monokai-sublime and there is no strikethrough for #Deprecated annotations. When I changed the color theme from monokai to darcula strikethrough worked as expected.
I found that the only thing that worked for me with version 2019.2 192.5728.98, runtime 11.0.3+12-b304.10 was to use Help | Edit VM Options and add -Dide.text.effect.new.metrics=false

Where is _kCLLocationAccuracyBest defined?

If I want to use it, should I add a framework or just header file?
I got this error that it's a symbol not found
According to the docs, it's declared in CLLocation.h. You should add the CoreLocation framework. Also, it appears to have no underscore out in front. That could be your problem.

How can I distinguish a plugin from a fragment?

I need to find the nature of the projects in my workspace. I found the IProject.getDescription().getNatureIds() method. as I see, both a plug-in and a fragment have the same natures. So this is not the right way to go.
Any other ideas ?
Thank you
I found the following:
IPluginModelBase[] workspaceModels = PDECore.getDefault().getModelManager().getWorkspaceModels(); and there is a isFragmentModel() method in IPluginModelBase
