Hi,

If your code the accessing the same function then you should avoid the dead lock.

You can use the synchronize block to prevent the current access to the same code.

synchronized(this){
   //Your database access code here.   
}

If your database updates takes the long time then the code block at particular line of code will wait for the updates to be completed. You can't skip the update and run the code blow.

If you you provide us more details we will may suggest you better solution.

Thanks
