What about other activities? do we need to check each activity with if and else and then use that LocaleHelper class?

[shabab]

whoa man! this is great.. i spent hours trying to figure out why the locale isn't changing in a lollipop device, finally your tutorial fixed the issue. thank you. keep up the good work..

[leolima]

I did not understand. If the native language of my device is in English, and change to French, just create the strings, no?
Example below:

res/Values-en:

<string name="app_name">My</string>

res/Value-fr:

<string name="app_name">Ma</string>

And when the user accesses the App in the user's official language, the string is automatically replaced, no?

[pranavkurkure]

I tried adding this feature of app tested on single field. But instead of converting that field into its hindi version it just translated to Namatse Duniya.

[amanbhatia]

Not usefull. i know there is a program where we can change language of whole app without this if else.

[chauhanumesh]

We close the app
and restart.
The language we chose.
The preferred language is no longer there
