[Android Software/Hacking General [Developers Only]] MaxFTW:
Hello, guys! As I can see there a lot of Polish people (like me) I decided to make Polish language for your favourite AROMA Installer.

DOWNLOAD HERE!

Instructions:

Download file from the link above

Don't change its name

Paste it into META-INF/com/google/android/aroma/langs

Open aroma-config file in text editor (Notepad++ recommended)

Find language selection section

Copy the last position and edit it, so it will look like that (REMOVE COMA IN NEW ONE, ADD IN PREVIOUS! CHANGE NUMBERS!):

"German", "Willkommen bei Installer",	0,	#-- selected.0 = 10
"Polish", "Witamy w instalatorze!",	0	#-- selected.0 = 11

Now find last if prop:

if prop("lang.prop","selected.0")=="xyz" then
loadlang("langs/xyz.lang");
fontresload( "0", "ttf/Roboto-Regular.ttf", "12" );
fontresload( "1", "ttf/Roboto-Regular.ttf", "18" );
endif;

...copy it, and mod it so it will look like that:

if prop("lang.prop","selected.0")=="10" then
loadlang("langs/de.lang");
fontresload( "0", "ttf/Roboto-Regular.ttf", "12" );
fontresload( "1", "ttf/Roboto-Regular.ttf", "18" );
endif;

if prop("lang.prop","selected.0")=="11" then
loadlang("langs/pl.lang");
fontresload( "0", "ttf/Roboto-Regular.ttf", "12" );
fontresload( "1", "ttf/Roboto-Regular.ttf", "18" );
endif;

Save the aroma-config file.

Finally your aroma-config should look like this (edited language section is shown here):

#---------------------------------[ Selectbox Without Group ]----------------------------------#
# TITLE | SUBTITLE | Initial Value #
#------------------+-----------------------------------------------------------+---------------#

"English", "Welcome to installer", 1, #-- selected.0 = 1
"Indonesian", "Selamat datang di installer", 0, #-- selected.0 = 2
"Espanol", "Bienvenido al instalador", 0, #-- selected.0 = 3
"Simplified Chinese","?????????", 0, #-- selected.0 = 4
"Arabic", "?????????", 0, #-- selected.0 = 5
"French", "Bienvenue dans l'installateur", 0, #-- selected.0 = 6
"Russian", "?????????", 0, #-- selected.0 = 7
"Italian", "Benvenuti installer", 0, #-- selected.0 = 8
"Hebrew", "?????????",	0,	#-- selected.0 = 9
"German", "Willkommen bei Installer",	0,	#-- selected.0 = 10
"Polish", "Witamy w instalatorze!",	0	#-- selected.0 = 11
#--------[ Initial Value = 0: Unselected, 1: Selected, 2: Group Item, 3: Not Visible ]---------#
);

##
# SET LANGUAGE & FONT FAMILY
#
if prop("lang.prop","selected.0")=="1" then
loadlang("langs/en.lang");
fontresload( "0", "ttf/Roboto-Regular.ttf", "12" ); #-- "0" = Small Font ( Look at Fonts & UNICODE Demo Below )
fontresload( "1", "ttf/Roboto-Regular.ttf", "18" ); #-- "1" = Big Font
endif;

if prop("lang.prop","selected.0")=="2" then
loadlang("langs/id.lang");
fontresload( "0", "ttf/Roboto-Regular.ttf", "12" );
fontresload( "1", "ttf/Roboto-Regular.ttf", "18" );
endif;

if prop("lang.prop","selected.0")=="3" then
loadlang("langs/es.lang");
fontresload( "0", "ttf/Roboto-Regular.ttf", "12" );
fontresload( "1", "ttf/Roboto-Regular.ttf", "18" );
endif;

if prop("lang.prop","selected.0")=="4" then
loadlang("langs/cn.lang");
fontresload( "0", "ttf/DroidSansFallback.ttf;ttf/Roboto-Regular.ttf", "12" ); #-- Use sets of font (Font Family)
fontresload( "1", "ttf/DroidSansFallback.ttf;ttf/Roboto-Regular.ttf", "18" );
endif;

if prop("lang.prop","selected.0")=="5" then
loadlang("langs/ar.lang");
fontresload( "0", "ttf/DroidSansArabic.ttf;ttf/Roboto-Regular.ttf", "12" ); #-- Use sets of font (Font Family)
fontresload( "1", "ttf/DroidSansArabic.ttf;ttf/Roboto-Regular.ttf", "18" );
endif;

if prop("lang.prop","selected.0")=="6" then
loadlang("langs/fr.lang");
fontresload( "0", "ttf/Roboto-Regular.ttf", "12" );
fontresload( "1", "ttf/Roboto-Regular.ttf", "18" );
endif;

if prop("lang.prop","selected.0")=="7" then
loadlang("langs/ru.lang");
fontresload( "0", "ttf/Roboto-Regular.ttf", "12" );
fontresload( "1", "ttf/Roboto-Regular.ttf", "18" );
endif;

if prop("lang.prop","selected.0")=="8" then
loadlang("langs/it.lang");
fontresload( "0", "ttf/Roboto-Regular.ttf", "12" );
fontresload( "1", "ttf/Roboto-Regular.ttf", "18" );
endif;

if prop("lang.prop","selected.0")=="9" then
loadlang("langs/he.lang");
fontresload( "0", "ttf/Roboto-Regular.ttf", "12" );
fontresload( "1", "ttf/Roboto-Regular.ttf", "18" );
endif;

if prop("lang.prop","selected.0")=="10" then
loadlang("langs/de.lang");
fontresload( "0", "ttf/Roboto-Regular.ttf", "12" );
fontresload( "1", "ttf/Roboto-Regular.ttf", "18" );
endif;

if prop("lang.prop","selected.0")=="11" then
loadlang("langs/pl.lang");
fontresload( "0", "ttf/Roboto-Regular.ttf", "12" );
fontresload( "1", "ttf/Roboto-Regular.ttf", "18" );
endif;

Done. Now you can enjoy Polish language in your AROMA Installer.
