NDK下的nativeCode使用android 原生碼的lib問題
是這樣的,有兩個問題請教
1.有無android tools可以dump library 的symbol
2.我在編譯android的原生碼後,會有一些lib,這些lib我可否再寫app的時候使用?
比如說libutils裡面的uptimeMillis(),雖然可以編譯,但是在link的時候會有如
下的錯誤,此問題該如何解?
error: undefined reference to 'android::uptimeMillis()'
以下為測試程式
#include "SystemClock.h"
SourceDemo::SourceDemo()
{
uptimeMillis();
}
以下為android.mk
