Move to the previous/next function in AndroidStudio (Vim Emulator)

I'm a vim user and recently I started learning writing apps for Android.
I use Android Studio 2.3.2 with Vim emulator.

As it comes to Vim- I usually use it for C++ programming and one of the features I use on a daily basis is ]] to move to the next function and [[ to get to the previous function.

When I use that in Android Studio it just moves me to the beginning/end of the file.

My guess is that it is related with opening function scope in the same line instead of in the new line.

Question:

Is that possible to jump to next/previous function using Android Studio Vim emulator just as I used to do in C++ code (even though I use Java coding style, a.k.a. "egyptian brackets")?

From the docs :help ]]

                            *]]*
]]          [count] sections forward or to the next '{' in the
            first column.  When used after an operator, then also
            stops below a '}' in the first column.  |exclusive|
            Note that |exclusive-linewise| often applies.

Which means it just goes to the next statement that has '{' as the first character of the line, which happens to be the case C and C++ functions (at least in some styleguides), as methods and functions start with a {, without any type of nesting.

However, when writing Java, methods are nested inside of classes, which means they usually have a level of indentation.

According to this answer, Vim has the builtin [m and ]m mappings, to navigate methods.

                        *]m*
]m          Go to [count] next start of a method (for Java or
            similar structured language).  When not before the
            start of a method, jump to the start or end of the
            class.  When no '{' is found after the cursor, this is
            an error.  |exclusive| motion.

So, if you wish to use [[ and ]] for navigating methods, you could remap these in your ~/.ideavimrc.

nnoremap [[ [m
nnoremap ]] ]m
