Sometimes there are projects wherein Android's integrated
textual content control system does not work. For example, if we need to repair
a translation blunders, accurate an explanation, or upload a brand new language
while not having to installation a new version of the app, Android may not
allow it.
In our case we've got an software with this hassle. The
consumer has a portal through which he can control translations and trade texts
or add new languages while not having to provide new versions of the
software.
In this text, we are able to focus at the Android part of
the solution and the way it could be custom designed to combine with Jetpack
Compose.
Schooling
While the idea isn't to use the Android machine to do
translations, we are going to use this for a couple of factors:
Determine the keys of the texts to be translated.
In the occasion of an error, enter fallback values.
So we create a strings.Xml document as normal, but we do not
create one for every language, we simply recognition on one which we want to
display in case no translation is discovered. In our case this is, for example,
English
The lines that we outline in this report need to have the
equal name as the ones defined inside the backend (as we can use it later) and
the textual content that have to be displayed while the interpretation is
acquired inside the occasion of an errors.
Translator
Translator is a category accountable for coping with
translations and making them available to other packages.
The translator has 4 dependencies:
Context: to get
entry to the traces defined within the text file.
Api: in order to
down load new translations.
Database: for offline get admission to to translations.
Cache: for faster access to translations with out database
get right of entry to.
When we open the app and start the translator, it looks
after a few matters:
Request new
translations for the language of the app.
1. A) Update the database, if available.
2. Load the file into the cache.
By default, the translator resolve ask for the translation
of the language the app is in, and the app will in turn be mounted because the
language of the phone. If it isn't always one of the available languages, the
default language is English. (In our case, other programs may additionally have
one-of-a-kind requirements).
The call to the server facet returns the ultra-modern model
range in addition to the response with the interpretation. We need to send the
same price to the backend the following time we open the software to check for
modifications. In the event of modifications, most effective new or changed
texts are despatched to us on the server aspect, so that we can replace the
database while not having to down load all translations each time. If a
connection to the translation API can't be mounted, it is going to be used
within the database.
Great translator
When a translation is asked, the translator works with the
cache with the aid of default and uses unique stages as fallbacks:
We'll look for a key inside the cache in case it would not
work:
We are searching out a key inside the database:
j. If it's far detected, replace the cache
B. In the occasion of an error:
three. We take the interpretation this is in the strings.Xml
report
This process ensures that we usually choose the most
value-powerful and honest answer via simplest reverting to slower answers
within the occasion of an errors and simplest the use of the interpretation of
the XML file if we can't find this key.
Thanks to the getKey approach, we will get the name of the
text from the strings.Xml report the usage of its identifier. So we are able to
make the following calls:
This guarantees that we keep away from typing errors when
asking for About
