 android編譯framework架包運行報錯

http://blog.csdn.net/cqupt_chen/article/details/8163632

最近在看frameworks裡的源碼，手癢了，便想改改看看效果，沒想到改完後，模擬器卻運行不起來了。
        首先聲明，我是用的android 4.0.3 ICS的源碼，編譯好後，利用編譯好的鏡像啟動的模擬器，以前修改過裡面的Launcher，將產生的Launcher.apk和Launcher.odex  push後是成功的。
現在我在
frameworks/base/policy/src/com/android/internal/policy/impl/LockScreen.java
frameworks/base/core/java/com/android/internal/widget/multiwaveview/MultiWaveView.java
中加了一點log,其實就是解鎖時相應的輸出座標等資訊，
試了兩種方法：
1. make framework  
  make snod

2.  在framework/base中mm
  adb push framework.jar 和 framework.odex 到 system/framework/

結果都是在啟動模擬器時，在開機顯示 android字樣時進不去了，ddms中不停的列印如下資訊：

後來根據高手的提示，去看 build/core/main.mk，發現裡面有個droidcore命令，
嘗試使用make droidcore編譯後，模擬器成功運行，並列印出修改的log，後來仔細分析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)
發現一開始是執行systemimage,於是我又嘗試用make systemimage來編譯:
修改framework中源碼，在framework/base 中mm,退至源碼根目錄，make systemimage後，啟動模擬器，修改效果成功顯示。
Ps：
1.貌似執行make snod(systemimage no dependence)不行，看來要編上dependence才行。
2.在make systemimage 之後一定要關閉模擬器重開才行，執行adb shell stop,adb shell start也不行。
就是時間比較長，編一下要10分鐘左右。
