[Android Q&A, Help & Troubleshooting] vinodsksagar:
Dear All,

I am working on 3G modem integration with Android .I am using Texas Instruments am335X Starter kit and and Android Source Provided by Texas. I have Integrated Driver For 3G modem with this Android Source.

3g Modem gets Connected to Internet and also it can browse the web pages for some time.

I analysed RAM usage From Settings App. While Running The Browser I can See 80 to 90 MB of Free RAM Space.

Still Starter kit becomes unresponsive and gets hanged and restarts.

From the Logcats it seems to be an issue of swap cache . Please Suggest How can I resolve this Issue?

Followings are my logcat messages:->
