In API 7 when try

val string = "string"
val bytes = string.toByteArray(Charset.forName("UTF-8"))

i have exception

java.lang.NoSuchMethodError: java.lang.String.getBytes

Is any way to get bytes from string without standard method? Looks like, convertation string to byte array starts with Api 8.

CodePudding user response：

There are versions of getBytes() on String that work back to API Level 1, such as this one.

ChatGPT help me :)

String string = "your_string";
ByteBuffer byteBuffer = Charset.forName("UTF-8").encode(string);
byte[] byteArray = byteBuffer.array();
