i am getting this message in logcat A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks. where to look for leak and what does it meant by " See java.io.Closeable"
That means you have opened something but never close them.Closable
have a method close
which you must call to release the resources associated with the component when you no longer need it.
To look for the leak, you can try MAT
, I often use it to find memory leaks(static data holding a reference to Activity, etc).
