音频文件头解析信息（艺术家、姓名）为乱码

音频文件头解析信息（艺术家、名称）为乱码

语言设置为英文，扫描时是不进行编码设置的。修改为默认编码方式为简体中文即可
1、MediaScannerClient.cpp在void MediaScannerClient::setLocale(const char* locale)方法中加入一个判断语句
void MediaScannerClient::setLocale(const char* locale)
{
?LOGE("MediaScannerClient.cpp->MediaScannerClient::setLocale，本地编码格式： %s\n", locale);
??? if (!locale) return;

??? if (!strncmp(locale, "ja", 2))
??????? mLocaleEncoding = kEncodingShiftJIS;
??? else if (!strncmp(locale, "ko", 2))
??????? mLocaleEncoding = kEncodingEUCKR;
??? else if (!strncmp(locale, "zh", 2)) {
??????? if (!strcmp(locale, "zh_CN")) {
??????????? // simplified chinese for mainland China
??????????? mLocaleEncoding = kEncodingGBK;
??????? } else {
??????????? // assume traditional for non-mainland Chinese locales (Taiwan, Hong Kong, Singapore)
??????????? mLocaleEncoding = kEncodingBig5;
??????? }
??? }else{
???????? mLocaleEncoding = kEncodingGBK;
??? }
}
