I had build an android sdk,I wanted to modify a apk which under the path "/system/app",but I am fail. When I added a jni interface to apk,I don`t know why it worked well with Eclipse ,but not in source code when I useed "mmm /package/apps/TimeSync".It show me"not jni.h".Then I builded the jni with "$NDK/ndk-build" first,and I got the lib***.so in the "./libs","../obj", and delete the file "jni/Android.mk", the cmd "mmm /package/apps/TimeSync" worked. But when I install the apk to the device,FC appeared and logcat showed "java.lang.UnsatisfiedLinkError:Library *** not found". And I push the lib***.so into the device "/system/lib", the apk worked.
Now I have some questions:
When I build the apk in Eclipse, does Eclipse put the lib***.so into apk? Or does Eclipse push the lib***.so into device with "adb push lib***.so /system/lib" directly?
If I install a apk with lib***.so with Eclipse,where can I find the lib***.so in the device? Is the "/system/lib" or "/data/data/..."?
Why it show me "not jni.h"? How to do when I want to build the jni with "mmm /package/apps/TimeSync"?
