Hi,

I would like to instrument the AOSP and especially the ART in order to log all methods called by a targeted application.

For now, I have simply modified the art_method.cc in art/runtime/mirror with the following :

---------------------------------------------------------------------------------------------------------------------------------------------------------------
void ArtMethod::Invoke(Thread* self, uint32_t* args, uint32_t args_size, JValue* result, const char* shorty) {
     [...]
     LOG(INFO) << "DYNAMIC ANALYSIS : " << GetDeclaringClassDescriptor() << "." << GetName();
     [...]
}
--------------------------------------------------------------------------------------------------------------------------------------------------------------

It works but it seems that it logs just a subset of the methods called. It seems like I am logging internal methods of the ART.
I though all methods execution would have crossed the ArtMethod::Invoke. Am I missing something ?

Example when I open the gallery application :

---------------------------------------------------------------------------------------------------------------------------------------------------------------
user@host - adb shell

shell@android:/ $ top | grep 19720
19720 3 0% S 18 1219840K 39920K fg u0_a28 com.android.gallery3d
19720 3 0% S 18 1219840K 39920K fg u0_a28 com.android.gallery3d
^C

shell@android:/ $ exit

user@host - adb logcat | grep 19720 | grep DYNAMIC
