caching - How to use Cache.getOrElse(java.lang.String key, java.util.concurrent.Callable<T> block, int expiration) -

-

how use cache.getorelse(java.lang.string key, java.util.concurrent.callable block, int expiration) give me example？ point how use “expiration",i know means expire time.

by way: want save object cache,and set expire time. when expire time,i can reset object cache.

thanks.

expiration number of seconds object hold in cache. if pass 0 expiration cache doesn't expire , have control hand.

what getorelse check cache, if object not there call callable block passing , adds result cache number of seconds passing expiration time.

i based comment in play framework cache javadoc.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
