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).
For me the problem happened because I was overriding the method onBackPressed()
without calling the super()
@Override
public void onBackPressed() {
//some coding here
super.onBackPressed();
}
if you see something like:

in your stacktrace, there is a known bug in older versions of okhttp that you can avoid by forcing the use of a newer version in your gradle file.
compile 'com.squareup.okhttp3:okhttp:3.2.0'
that solved a very similar problem for me at least.
