I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
Joshua Weinberg's answer is mostly correct, however the Ox prefix is optional when scanning hexadecimal integers. If you have a string in the format #01FFFFAB, you can still use an NSScanner, but you can simply skip the first character.
ReplyDeleteunsigned result = 0;
NSScanner *scanner = [NSScanner scannerWithString:@"#01FFFFAB"];
[scanner setScanLocation:1]; // bypass '#' character
[scanner scanHexInt:&result];
you can use NSScanner for this
ReplyDeleteint outVal;
NSScanner* scanner = [NSScanner scannerWithString:@"0x01FFFFAB];
[scanner scanHexInt:&outVal];
outVal will contain the int you're looking for. The 0x is optional.
strtol() is your friend.
ReplyDeleteIt converts a string to a long, and you can pass the base of the number in. Strip that # sign off first though, or pass to strtol a pointer to the first numerical character.
