In Java program, we can use following codes to get the system memory info:
===============================================================
ActivityManager activityManager = (ActivityManager)
getSystemService(ACTIVITY_SERVICE);
MemoryInfo info = new MemoryInfo();
activityManager.*getMemoryInfo*(info);
===============================================================
But now, we need to get system memory info from Native C program. So, I have
to implement following codes to new "MemoryInfo" object:
===============================================================
jclass cls = env->FindClass("android/app/ActivityManager$MemoryInfo");
jmethodID ctor = env->GetMethodID(cls, "<init>", "()V");
jobject *objMemoryInfo* = env->NewObject(cls, ctor);
===============================================================
Up to now, we have got the MemoryInfo's object "objMemoryInfo".
Then I need to input "*objMemoryInfo*" to "*parcelMemoryInfo*", but don't
how to convert from Parcelable to Parcel:
===============================================================
int GET_MEMORY_INFO_TRANSACTION = IBinder::FIRST_CALL_TRANSACTION+75;
sp<IServiceManager> sm = defaultServiceManager();
sp<IBinder> am = sm->getService(String16("activity"));
Parcel *parcelMemoryInfo* = *objMemoryInfo*; * //HERE: how to convert
from Parcelable to Parcel
* Parcel reply;
status_t ret = am->transact(GET_MEMORY_INFO_TRANSACTION, *
parcelMemoryInfo*, &reply);
===============================================================
Thanks.
