When comparing Eclipse + Android Development Tools plugin vs Qt Creator, the Slant community recommends Qt Creator for most people. In the question“What are the best IDEs for Android development?” Qt Creator is ranked 9th while Eclipse + Android Development Tools plugin is ranked 12th. The most important reason people chose Qt Creator is:
Qt Creator has a code model which basically has the same information as the compiler. So it can do really nice syntax highlighting (e.g. of virtual methods or local variables) as well as provide great code completion.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Good offline capabilities
Pro Free and open source
Eclipse is a free and open source software, it's released under the Eclipse Public license.
Pro Java programming language and XML editors
Has full support for both Java and XML.
Pro Large selection of plugins
Eclipse has a large and active community, which has resulted in a wide variety of plugins.
Pro Graphical interface
ADT provides GUI access to many of the command line SDK.
Pro Highly customizable
Thanks to the large variety of plugins and various configuration options, Eclipse is very customizable.
Pro Good font rendering
Because Eclipse is based on SWT, it uses the native font rendering and thus looks better than other IDEs on some Linux systems, where the Java font rendering is not optimal.
Pro Great syntax highlighting and auto-completion
Qt Creator has a code model which basically has the same information as the compiler. So it can do really nice syntax highlighting (e.g. of virtual methods or local variables) as well as provide great code completion.
Pro Integrates well with non-IDE workflows
Qt Creator uses normal .pro-files, CMakeLists.txt, Makefiles.am, etc. for its projects and rarely needs special configuration for projects.
Projects can be built on the command line as usual.
Pro Built-in Qt GUI editor
Allows for the creation of a window based UI in a graphical editor, no code required to build the UI.
Pro Fast and fully keyboard-navigatable
Responsive UI, no need to use the mouse for the power users.
Pro Supports CMake
Pro Very responsive when compared to similar software
Pro Much space dedicated to the code
Small and beautiful UI, almost all the space is dedicated to the text with hardly and toolbars. Can actually be used on a 1024x768 pixel screen.
Cons
Con A lot of bugs and weak debugger
False errors cannot be removed.
Con Plugins can be unstable
Though there are plenty of plugins to choose from, they aren't always reliable. Some aren't maintained, bug fixes can be slow, and you may need to download plugins from multiple sources.
Con May lose support in the future
Google recommends moving away from Eclipse for Android Development, plugins and features are adopted much later from Eclipse than from Android Studio or IntelliJ IDEA and in the future the ADT plugin may be abandoned altogether.
Con Poor refactoring
QtCreator has lack of refactoring features. It's not even close to Resharper++ or CLion.
Con Poor multi-window mode support
While multiple windows are supported, many operations will activate in the primary window (debug, goto-line... etc).
Con Qt-focused
Qt Creator is focused on being an IDE for Qt, as a general purpose IDE it performs quite well, but there are areas which are lacking such as project file support (support for generic/CMake projects lags behind Qt projects).
