Android yellow warning Summary

1.

Warning:

// To get local formatting use getDateInstance (), getDateTimeInstance (), or

// GetTimeInstance (), or use new SimpleDateFormat (String template, Locale

// Locale) with for example Locale. US for ASCII dates. @ SuppressLint ("SimpleDateFormat ")

String string = new SimpleDateFormat("EEEE  yyyy-MM-dd",Locale.getDefault()).format(new Date());

Solution:

Add Locale. getDefault ()

For example, like:

SimpleDateFormat newSimpleDateFormat = new SimpleDateFormat ("MM, dd, yyyy HH mm", Locale. getDefault ());

2. Warning:

Implicitly using the default locale is a common source of bugs: Use toUpperCase (Locale) instead

String string = new SimpleDateFormat ("EEEE", Locale. getDefault (). format (new Date (). toUpperCase ();

Solution:

Because uppercase is generally used only in English-speaking countries, Locale is specified as Locale. US.

String string = new SimpleDateFormat ("EEEE", Locale. getDefault (). format (new Date (). toUpperCase (Locale. US );

(Sometimes the warning prompt is still in progress and must be cleaned)
