Hi Ashok,
Please provide a step-by-step guide on how to enable an android app for CA.
Unfortunately, the sample app
<iotivity>/resource/csdk/connectivity/samples/android/sample_service/ isn?t
buildable as the function signatures do not seem to match the APIs exposed by
the CA on master branch.
FYI: The runtime issue outlined previously is caused by the g_jvm not being set
while the following lines are executed:
void CACreateWiFiJNIInterfaceObject(jobject context)
{
JNIEnv* env;
if ((*g_jvm)->GetEnv(g_jvm, (void**) &env, JNI_VERSION_1_6) !=
JNI_OK)
I guess, this should help you to trace the problem.
I wonder if a phone call may help us to sort things out?
Thank you,
Tim

Hi Tim,
Please find my comments inline.
Hope this gives a clear picture about how CA interacts with Android APIs.
Please share us the location where we can keep our Java files so that you can
create the JAR/AAR files based on your requirements
Best Regards,
Ashok JN

<!--[if mso 9]-->
Hi Ashok,
Thank you for your reply.
We have found your sample application inside of
<iotivity>/resource/csdk/connectivity/samples/android/sample_service/
If I read it correctly, the current implementation of the connectivity
abstraction for Android assumes that an application developer will provide an
implementation of the native interfaces which are required by the CA to
function on Android. Is this correct?
[Ashok] Not really. CA has to invoke Android interfaces like
BroadcastReceivers, and Callbacks for Bluetooth, WiFi, and BT. Currently JNI
layer expects Context to invoke android/Java APIs .
Except this Context, Application does not have to provide/implement any other
functionalities
If this is the case, I was wondering if you have considered moving the desired
implementations into the Android API library (.aar file)? If this was the
intent, how long do you think it may take?
[Ashok] If Android API branch takes a decision regarding how to provide the
context to the below layers, for accessing Android APIs, that will be helpful
and everyone can follow that. This will remove the only dependency with the
application.
Best regards,
Tim

Hi Tim,
CAInitialize intern will call CAWiFiInitialize. This will try to create the
instance of cawifiinterface Android Java object from the JNI. This interface
implements the Broadcast receiver to receive WiFi Connection Status and update
the status to JNI Layer. CA intern will update the network status through the
callback
The current crash is caused as it cannot locate the wifiinterface in the JNI
layer.
These Java files are placed at
samples/android/sample_service/src/com.iotivity.jar. Please bundle the
necessary Jar file with the Application based on the Transport (WIFI/BLE/EDR)
and the problem will be resolved. Please let us know if you have other issues.
Best Regards,
Ashok

Title : [dev] runtime issue: merged master/CA built for Android
Hi All,
Please take a look at the log file below. We are seeing a crash inside of
CACreateWiFiJNIInterfaceObject function. The codebase is built with
TARGET_TRANSPORT=WIFI.
It seems like CAWiFiJniInit is never called.
Are we missing anything?
Thanks,
Tim
