Porting android2.2 on OMAP

 Hi all ,

 

May be it's not right place to ask this question but since it's related to OMAP so i am hoping for response.


I am trying to port android 2.2 on OMAP..What I"m getting that same way of porting was working in 2.1 but not with 2.2...

I have an object that is used for calling callback functions -----
static jobject o;

i have assigned the callback function to that object through a pointer, env -----

o=env->NewGlobalRef(callback);

The same pointer, env, points towards the function CallVoidMethod( )
that uses JNI to reach to the java code.

env->CallVoidMethod(o, methodId, pDeviceId, deviceStatus,
statusReason, connectionProgressInfo);

However on calling this function, the system is getting crashed, and
VM says that it's an invalid reference to static jobject o and then it
crashes.

My code is as follows :

static jint android_net_wimax_subscribeDeviceStatusChange(JNIE nv*
env, jobject clazz, jobject jdeviceId, jobject callback) {

// LOGD(" android_net_wimax_subscribeDeviceStatusChange() ->D1"); o =
env->NewGlobalRef(callback); //o = callback;

// LOGD(" android_net_wimax_subscribeDeviceStatusChange() ->D2");

return (jint)::SubscribeDeviceStatusChange(deviceId,
fun_IndDeviceStatusUpdate); }

void fun_IndDeviceStatusUpdate(WIMAX_API_DEVICE_ID_P pDeviceId,
WIMAX_API_DEVICE_STATUS deviceStatus, WIMAX_API_STATUS_REASON
statusReason, WIMAX_API_CONNECTION_PROGRESS_INFO
connectionProgressInfo) {

JNIEnv *env = NULL; int nResult = -1;

// LOGD(" AttachCurrentThread() ->D1");

nResult = g_jVM->AttachCurrentThread(&env, NULL);

// LOGD(" AttachCurrentThread() ->D2-%d",nResult);

if ((nResult != 0) || (env == NULL)) { LOGD(" AttachCurrentThread()
failed"); } else { // LOGD(" AttachCurrentThread() ->D3");

if(o == NULL) {

LOGD(" o is NULL ");

} else { LOGD(" o is not NULL ");
}

jclass cls = env->GetObjectClass(o);

// LOGD(" AttachCurrentThread() ->D4"); jmethodID methodId = env-

>GetMethodID(cls, "callback", "(Landroid/net/wimax/structs/

DeviceId;III)V");

// LOGD(" AttachCurrentThread() failed->D5"); if (methodId) { env-

>CallVoidMethod(o, methodId, pDeviceId, deviceStatus, statusReason,

connectionProgressInfo); }

if (g_jVM->DetachCurrentThread() != JNI_OK) { LOGE("%s:
DetachCurrentThread() failed", FUNCTION); } }

// LOGD("JNI->CALLBACK->D3");

}

*******
My error log is as follows

<<< D/wimax   ( 1673): before CallVoidMethod()
W/dalvikvm( 1673): JNI WARNING: 0x48e31dec is not a valid JNI

According to me problem is in "pDeviceId" which is getting wrong address or mismatch with reference. if so then how can I solve it and if not, then what's the problem and how to solve it.

Kindly help me out, thanks in advance
