AOSP 添加我的第一行代码

目标 在 Activity 的 onCreate 中添加一句 log 找到 Activity

find . -name Activity.java

找到 Activity 在 ./frameworks/base/core/java/android/app/Activity.java

@MainThread

@CallSuper

protected void onCreate(@Nullable Bundle savedInstanceState) {

	if (DEBUG_LIFECYCLE) Slog.v(TAG, "onCreate " + this + ": " + savedInstanceState);
	
	Log.i("heinika","onCreate Hello Heinika!!");
