+====== Crosswalk development ======
+Here is described only development OF Crosswalk and NOT WITH Crosswalk. In other words: how do I build and develop Crosswalk package.

+===== Fetching sources =====
+The fetching procedure is described in [[https://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools_tutorial.html#_setting_up|depot_tools tutorial]]. Here is my short description.
+Fetch depot_tools:
+<code bash>
+git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
+</code>
+Add the path of depot_tools to PATH environment variable:
+<code bash>
+export PATH=$PATH:/path/to/depot_tools
+</code>
+After that go to an empty directory, where the source should be downloaded and fetch chromium for android:
+<code bash>
+fetch android
+</code>
+(''fetch chromium'' or ''fetch ios'' are possible too, but we need only android)
+If you are on linux and fetching the code for the first time, then you’ll need to run:
+<code bash>
+cd src && ./build/install-build-deps.sh
+</code>
+And finally:
+<code bash>
+gclient sync
+</code>
+This will pull all dependencies of the Chromium src checkout. You will need to run this any time you update the main src checkout, including when you switch branches.
+===== Crosswalk 23 and later. GN setup =====
+All things after the line were not done by me. Currently it is simply a "plan".
+----
+The following is copied from [[https://crosswalk-project.org/contribute/building_crosswalk/android_build.html|Crosswalk - Android build instructions]]
+In order to build Crosswalk, you need to have at least two lines in your settings to pull some default variables we set:
+<code bash>
+# important: WITH 'src' at the line end (in the official guide without!)
+cd /path/to/crosswalk-checkout/src
+gn args out/Default
+</code>
+A text editor will be shown, where you must add the following line:
+<code bash>
+import("//xwalk/build/android.gni")
+target_os = "android"
+</code>
+You can add other settings after this statement, such as is_debug = false for a release build or target_arch = "x64" to create a 64-bit IA build. By default, target_arch is set to arm, which creates a 32-bit ARM build.
+Once you have done this once, you can later call gn gen out/Default to just regenerate the ninja files based on your existing settings if you need to (most of the time, this will be done automatically for you when building).
+See Chromium's [[https://www.chromium.org/developers/gn-build-configuration|page about GN]] for more information, including other common settings.
+===== Building Crosswalk =====
+Now we can build Crosswalk:
+<code bash>
+cd C:\path\to\crosswalk-checkout\src
+ninja -C YOUR-BUILD-DIR xwalk
+</code>
+YOUR-BUILD-DIR can be freely choosen, for example: "out/Default".
+===== Changed files =====
+Because of my wrong configuration (clang was enabled), so some files could not be compiled. This files were changed by me:
+/home/development/chromiumdev/crosswalk/src/xwalk/runtime/browser/xwalk_content_browser_client.h\\
+/home/development/chromiumdev/crosswalk/src/xwalk/runtime/browser/android/net/xwalk_url_request_job_factory.h\\
+/home/development/chromiumdev/crosswalk/src/xwalk/extensions/common/android/xwalk_extension_android.h\\
