Android 1.5 ALSA 和 Bluetooth的一點小問題

Android 1.5 ALSA 和 Bluetooth的一點小問題

ALSA 要在system/core/init/device.c加上一段代碼以創建/dev/snd:

if(!strncmp(uevent->subsystem, "graphics", 8)) {
base = "/dev/graphics/";
mkdir(base, 0755);
} else if (!strncmp(uevent->subsystem, "oncrpc", 6)) {
base = "/dev/oncrpc/";
mkdir(base, 0755);
} else if (!strncmp(uevent->subsystem, "adsp", 4)) {
base = "/dev/adsp/";
mkdir(base, 0755);
} else if(!strncmp(uevent->subsystem, "input", 5)) {
base = "/dev/input/";
mkdir(base, 0755);
} else if(!strncmp(uevent->subsystem, "mtd", 3)) {
base = "/dev/mtd/";
mkdir(base, 0755);
} else if(!strncmp(uevent->subsystem, "sound", 5)) {
base = "/dev/snd/";
mkdir(base, 0755);
} else if(!strncmp(uevent->subsystem, "misc", 4) &&
!strncmp(name, "log_", 4)) {
base = "/dev/log/";
mkdir(base, 0755);
name += 4;
} else
base = "/dev/";
}

Bluetooth:

要修改system/bluetooth/bluedroid/bluetooth.c中修改#define HCID_START_DELAY_SEC 5
