You do not need to decompress the package and directly read the specified file in the ZIP file. For example, the file/sdcard/a.zipcontains the file z.txt. The read procedure is as follows: int zfd = zip_open("/sdcard/a.zip/z.txt");if (ZIP_IS_VALID(zfd)) {zip_seek(zfd, 5, SEEK_SET);zip_read(zfd, buf, 10);zip_close(zfd);} 1. dependent on zipfilero. h In Android framework, which must be compiled in the
