android编译framework架包运行报错
http://blog.csdn.net/cqupt_chen/article/details/8163632
最近在看frameworks里的源码，手痒了，便想改改看看效果，没想到改完后，模拟器却运行不起来了。
首先声明，我是用的android 4.0.3
ICS的源码，编译好后，利用编译好的镜像启动的模拟器，以前修改过里面的Launcher，将生成的Launcher.apk和Launcher.odex
push后是成功的。
现在我在
frameworks/base/policy/src/com/android/internal/policy/impl/LockScreen.java
frameworks/base/core/java/com/android/internal/widget/multiwaveview/MultiWaveView.java
中加了一点log,其实就是解锁时相应的输出坐标等信息，
试了两种方法：
1.
make framework
make snod
2. 在framework/base中mm
adb push framework.jar 和 framework.odex
到 system/framework/
结果都是在启动模拟器时，在开机显示 android字样时进不去了，ddms中不停的打印如下信息：

后来根据高手的提示，去看
build/core/main.mk，发现里面有个droidcore命令，
尝试使用make
droidcore编译后，模拟器成功运行，并打印出修改的log，后来仔细分析droidcore：
755 .PHONY: droidcore
756
droidcore: files \
757 systemimage
\
758 $(INSTALLED_BOOTIMAGE_TARGET)
\
759 $(INSTALLED_RECOVERYIMAGE_TARGET)
\
760 $(INSTALLED_USERDATAIMAGE_TARGET)
\
761
$(INSTALLED_FILES_FILE)
发现一开始是执行systemimage,于是我又尝试用make
systemimage来编译:
修改framework中源码，在framework/base 中mm,退至源码根目录，make
systemimage后，启动模拟器，修改效果成功显示。
Ps：
1.貌似执行make snod(systemimage no
dependence)不行，看来要编上dependence才行。
2.在make systemimage 之后一定要关闭模拟器重开才行，执行adb
shell stop,adb shell start也不行。
就是时间比较长，编一下要10分钟左右。
