status_t Parcel::writeString8(const String8& str)

{

    status_t err = writeInt32(str.bytes());

    if (err == NO_ERROR) {

    // only write string if its length is more than zero characters,

    // as readString8 will only read if the length field is non-zero.

    // this is slightly different from how writeString16 works.

    if (str.bytes() > 0 && err == NO_ERROR) {

        err = write(str.string(), str.bytes()+1);
