根据项目需要，最近在研究sip协议和sipdroid的源码
我看很多朋友提到使用2.3以上模拟器调试的时候，SipManager为空
if (manager == null) {
manager = SipManager.newInstance(this);//manager 为null
}
是因为模拟器不支持sip,所以只有用以下办法修改framework 重新编译IMG文件
1. Make the system partition writeable. Open a cmd window and enter these:
emulator -avd <avdname> -partition-size 128
adb shell mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
2. Enable SIP support:
Copy 2 XMLs from AOSP into text files: android.software.sip.xml, android.software.sip.voip.xml, and copy XMLs to the emulator:
adb push android.software.sip.voip.xml /system/etc/permissions
adb push android.software.sip.xml /system/etc/permissions
3. Disable config_sip_wifi_only in config.xml: <bool name="config_sip_wifi_only">false</bool>
The repacked resource file can be found here (for SDK 2.3.3, API level: 10). Copy it to the emulator:
adb push framework-res.apk /system/framework
4. Close emulator and start it again in normal mode.
或者这里直接下载编译好的IMG文件

然后拷贝到你建的2.3的模拟器目录里 \.android\avd\<avdname>.avd
继续研究sip...以后还会陆续更新.
