Try to tag the data model/ data source with your list view view.setTag(dataModel) in getView method of your adapter class.

Why not try RecyclerView instead of ListView and use Fresco Image Library?

Bluetooth streaming is lagging Android app

I'm writinng Android app that receiving data via bluetooth from another device. Those data as in fact streaming non-stop. After getting about 50 or 70 of them, app slows down and stop showing me received data. App cache is full, but clearing it (deleting context.getCacheDir()) doesn't help. After restarting whole app, I can again get next part of data. WHat can I do for avoiding this "lag"?

Getting incoming calls for an hour only using Twilio

I have implemented Twilio in my android app for outgoing and incoming calls. But I'm facing an issue while getting incoming call with the background service. The issue is that I get calls in first 30-40 mins only. After sometime phone stops getting incoming calls. I tried so much. Please respond me soon. I'm sharing code with you too.
I get token from a background service which generates token after a time period.
