Error in registerActivity

[C C]

When I try to use advance sdk, I got the following error. It comes from registerActivity. I have no idea about what's wrong with the code, since it is the second line when initializing lib. Does anyone know any clue about this? Thanks.

Error message:

public void initializeLib()

{

libInstance = NxpNfcLib.getInstance();

libInstance.registerActivity(this, Constant.packageKey); 

....

}

Hi,

It seems that you have not included the library!

Please put the file nxpnfclib.jar in the directory libs. It will be found by Eclipse or Android Studio. Rebuild your project. It should works now.

Hi,

It seems that something with your project settings are wrong. The SDK has an enclosed sample project with runs out of the box. Did you try to build the sample app?
You can check how the library is included into the sample project.

Hi,

The sample app can work. I'm building my own app according to the sample app. The difference is that my app is a system app on Android. The error below shows that NxpLogUtils is trying to access external storage. I'm wondering what it tries to log to external storage? It seems that a system app cannot write to external storage. Can I forbid it from logging to external storage? Thanks.

Hi CC,

The external path is a standard source for logging. Typically the external storage is provided for Android software apps. Your particular case where you want to implement your application as system software was not anticipated and handled in the current releases so far.

I had a conversation with the development team and they have signalized that they want to provide a special release with switched off logging for you. The team expect that you test this release and give feedback to the team.

If you are interested, please let me know and use our address:

Hi,

It is really nice to know that a special release is possible. I've contacted you via your email. I'm not sure whether you have received my email, since I have not received any response yet. I use the same email address as I registered in this forum. I suspect my email address might be blocked...?

Hope to hear from you soon.
CC
