A way for Android to release memory

Step 1: Define a listening interface

 Public Static Interface Onlowmemorylistener {          void  onlowmemoryreceived ();      }   /* */

Add the following code to the Step 2:android application file

Initialization

Private Arraylist<weakreference<onlowmemorylistener>> mlowmemorylisteners;   /* */
 Public MyApp () {          new arraylist<weakreference<onlowmemorylistener>>();      }   /* */

Register for monitoring

 Public voidRegisteronlowmemorylistener (Onlowmemorylistener listener) {if(Listener! =NULL) {mlowmemorylisteners. Add (NewWeakreference<myapp.onlowmemorylistener>(listener)); }      }  //Remove Listener     Public voidUnregisteronlowmemorylistener (Onlowmemorylistener listener) {if(Listener! =NULL) {              inti = 0;  while(I <mlowmemorylisteners.size ()) {                  FinalOnlowmemorylistener L =Mlowmemorylisteners.get (i). get (); if(L = =NULL|| L = =listener)                  {Mlowmemorylisteners.remove (i); } Else{i++; }              }          }      }  /*how to ask Hovertree.com*/

When the memory space is too low, it is called by the system

@Override Public voidonlowmemory () {Super. Onlowmemory (); inti = 0;  while(I <mlowmemorylisteners.size ()) {              FinalOnlowmemorylistener L =Mlowmemorylisteners.get (i). get (); if(L = =NULL) {mlowmemorylisteners.remove (i); } Else{l.onlowmemoryreceived (); I++; }          }      }  /*how to ask Hovertree.com*/

Step 3: Where the memory is wasted, compared to the chip cache, you can implement and register this listener
