This is the line I need character encoding:

byte[] out = str.getBytes(StandardCharsets.UTF_8);

Answer 1

StandardCharsets was added in API Level 19. It is not available for any of the Jelly Bean versions of Android.

Answer 2

There are various overloaded .getBytes() method is declared in String Class.

  public void getBytes(int, int, byte[], int);
  public byte[] getBytes(java.lang.String) throws java.io.UnsupportedEncodingException;
  public byte[] getBytes(java.nio.charset.Charset);
  public byte[] getBytes();

You can use any of it. but you should try this..

 byte[] out = str.getBytes("UTF-8");

instead of

byte[] out = str.getBytes(StandardCharsets.UTF_8);
