I have an android app, which listens to a socket from the server and retrieves data in json format and save data in the database. Resource cursor adapter is used to display the data in a list. When the app is idle for 10 minutes or more, it is not reponding. Any solutions?
ANR occurs when the main thread is blocked for a few time. Specifically, 5 seconds in an Activity, 10 seconds in a BroadcastReceiver and 20 seconds in a Service. So, to avoid ANR, you need to ensure that you don't do something like these in you UI thread: reading or writing files, connecting the internet, operating databases and so on, which spend a lot of time. So, if you want to do things above, you may start a new thread to do that. Specifically, AsyncTask ThreadHandler and something like that.
I hope this will help you.
ANR occurs when Android detects the system is unable to respond to user input for more than a few seconds.
CursorWindow﹕ Window is full: requested allocation 396488 bytes,
free space 285853 bytes, window size 2097152 bytes
04-01 05:32:34.328 1598-1607/com.inxed W/CursorWrapperInner﹕
Cursor finalized without prior close()
you need to close the cursor.
ANR display if application cannot respond to the user input.According to the Google doc,you should not perform the work on the UI thread. I recommend you to perform network request or long running operation in worker thread instead of UI thread. for more this
It looks like your DB cursor its full. After saving data from the cursor, close it, set it to null and create a new one so no buffers are kept in memory.
