Android : SharedPreferences data lifetime
For example if I do it once in my application :
sharedPref.edit().putString("com.blablabla.name_user","COCORICO").apply();
Can I find the data as long as the application is installed ?
String name_user = sharedPref.getString("com.blablabla.name_user", "");
Except if I reinstall the application or if I overwrite the data,
the data will never be lost, even several months later ?

Why you think data should lost, unless you modified/deleted it?
You can read more about shared perferences here: https://developer.android.com/training/data-storage/shared-preferences
If you will uninstall application all shared perferences will be deleted. If it will be updated in correct way (signed with same keys) - not.
