Decode(ByteBuffer)
Decodes all bytes from the input byte buffer using the Base64
encoding scheme, writing the results into a newly-allocated ByteBuffer.

public virtual Java.Nio.ByteBuffer? Decode (Java.Nio.ByteBuffer? buffer);[<Android.Runtime.Register("decode", "(Ljava/nio/ByteBuffer;)Ljava/nio/ByteBuffer;", "GetDecode_Ljava_nio_ByteBuffer_Handler", ApiSince=26)>]
abstract member Decode : Java.Nio.ByteBuffer -> Java.Nio.ByteBuffer
override this.Decode : Java.Nio.ByteBuffer -> Java.Nio.ByteBufferParameters
- buffer
- ByteBuffer
the ByteBuffer to decode
Returns
A newly-allocated byte buffer containing the decoded bytes
- Attributes
Remarks
Decodes all bytes from the input byte buffer using the Base64 encoding scheme, writing the results into a newly-allocated ByteBuffer.
Upon return, the source buffer's position will be updated to its limit; its limit will not have been changed. The returned output buffer's position will be zero and its limit will be the number of resulting decoded bytes
IllegalArgumentException is thrown if the input buffer is not in valid Base64 encoding scheme. The position of the input buffer will not be advanced in this case.

Applies to
Decode(Byte[])
Decodes all bytes from the input byte array using the Base64
encoding scheme, writing the results into a newly-allocated output
byte array.
[Android.Runtime.Register("decode", "([B)[B", "GetDecode_arrayBHandler", ApiSince=26)]
public virtual byte[]? Decode (byte[]? src);[<Android.Runtime.Register("decode", "([B)[B", "GetDecode_arrayBHandler", ApiSince=26)>]
abstract member Decode : byte[] -> byte[]
override this.Decode : byte[] -> byte[]Parameters
- src
- Byte[]
the byte array to decode
Returns
A newly-allocated byte array containing the decoded bytes.
- Attributes
Remarks
Decodes all bytes from the input byte array using the Base64 encoding scheme, writing the results into a newly-allocated output byte array. The returned byte array is of the length of the resulting bytes.

Applies to
Decode(String)
Decodes a Base64 encoded String into a newly-allocated byte array
using the Base64 encoding scheme.
[Android.Runtime.Register("decode", "(Ljava/lang/String;)[B", "GetDecode_Ljava_lang_String_Handler", ApiSince=26)]
public virtual byte[]? Decode (string? src);[<Android.Runtime.Register("decode", "(Ljava/lang/String;)[B", "GetDecode_Ljava_lang_String_Handler", ApiSince=26)>]
abstract member Decode : string -> byte[]
override this.Decode : string -> byte[]Parameters
- src
- String
the string to decode
Returns
A newly-allocated byte array containing the decoded bytes.
- Attributes
Remarks
Decodes a Base64 encoded String into a newly-allocated byte array using the Base64 encoding scheme.
An invocation of this method has exactly the same effect as invoking decode(src.getBytes(StandardCharsets.ISO_8859_1))

Applies to
Decode(Byte[], Byte[])
Decodes all bytes from the input byte array using the Base64
encoding scheme, writing the results into the given output byte array,
starting at offset 0.
[Android.Runtime.Register("decode", "([B[B)I", "GetDecode_arrayBarrayBHandler", ApiSince=26)]
public virtual int Decode (byte[]? src, byte[]? dst);[<Android.Runtime.Register("decode", "([B[B)I", "GetDecode_arrayBarrayBHandler", ApiSince=26)>]
abstract member Decode : byte[] * byte[] -> int
override this.Decode : byte[] * byte[] -> intParameters
- src
- Byte[]
the byte array to decode
- dst
- Byte[]
the output byte array
Returns
The number of bytes written to the output byte array
- Attributes
Remarks
Decodes all bytes from the input byte array using the Base64 encoding scheme, writing the results into the given output byte array, starting at offset 0.
It is the responsibility of the invoker of this method to make sure the output byte array dst has enough space for decoding all bytes from the input byte array. No bytes will be written to the output byte array if the output byte array is not big enough.
If the input byte array is not in valid Base64 encoding scheme then some bytes may have been written to the output byte array before IllegalargumentException is thrown.
