问题原因： _voltagesArray是数组， SetObjectField应该给数组那个field赋值，付错了
jclass gpicls=sdkenv->GetObjectClass(batteryStatusobj);
jfieldID jvoltages = sdkenv->GetFieldID(gpicls, "voltages", "[S");
jfieldID jbattery_remaining = sdkenv->GetFieldID(gpicls, "battery_remaining", "B");
jfieldID jtemperature = sdkenv->GetFieldID(gpicls, "temperature", "S");
jshortArray _voltagesArray=sdkenv->NewShortArray(sizeof(info.voltages));
//memcpy(_voltagesArray,info.voltages,sizeof(info.voltages));
sdkenv->SetShortArrayRegion(_voltagesArray,0,9,(jshort *)info.voltages);
sdkenv->SetObjectField( batteryStatusobj,jvoltages,_voltagesArray);—— 这里错了，应该是jvoltages
sdkenv->SetByteField(batteryStatusobj, jbattery_remaining,info.battery_remaining);
sdkenv->SetShortField(batteryStatusobj, jtemperature,info.temperature);
sdkenv->CallVoidMethod(globalcallBack, jmid, info,batteryStatusobj);
