Hi
I am going to porting a USB-based GPS module to Android 2.3 on arm
device.
In the Android2.3 source,I find the file (sdk/emulator/gps/
gps_qemu.c). So i change the file and Android.mk, making them been
builded to gps.default.so and been copied to the directory (/system/
lib/hw/).
By doing these, i can grab the NMEA data and callback them to JNI.
However , When callback to GpsLocationProvider,
env->CallVoidMethod(mCallbacksObj, method_reportLocation, location-
>flags,
(jdouble)location->latitude, (jdouble)location->longitude,
(jdouble)location->altitude,
(jfloat)location->speed, (jfloat)location->bearing,
(jfloat)location->accuracy, (jlong)location->timestamp);
make the VM restart. What happen?
