Android code optimization----template notation for application nodes

Creates a new class MyApplication, inherited from application. The code is as follows:

Myapplication.java:

1  PackageCom.smyhvae.homepicdemo;2 3 Importandroid.app.Application;4 ImportAndroid.os.Handler;5 ImportAndroid.os.Looper;6 7 /**8 * Created by smyhvae on 2015/5/13.9  */Ten  Public classMyApplicationextendsApplication { One     //gets the context to the main thread A     Private StaticMyApplication Mcontext =NULL; -     //gets the handler to the main thread -     Private StaticHandler Mmainthreadhandler =NULL; the     //gets the looper to the main thread -     Private StaticLooper Mmainthreadlooper =NULL; -     //get to the main thread -     Private StaticThread Mmainthead =NULL; +     //gets the ID to the main thread -     Private Static intMmaintheadid; +  A @Override at      Public voidonCreate () { -         //TODO auto-generated Method Stub -         Super. OnCreate (); -          This. Mcontext = This; -          This. Mmainthreadhandler =NewHandler (); -          This. Mmainthreadlooper =Getmainlooper (); in          This. Mmainthead =Thread.CurrentThread (); -         //Android.os.Process.myUid () Gets the user ID to         //Android.os.Process.myPid () Gets the process ID +         //Android.os.Process.myTid () Gets the ID of the calling thread -          This. Mmaintheadid =Android.os.Process.myTid (); the     } *  $      Public StaticMyApplication getapplication () {Panax Notoginseng         returnMcontext; -     } the  +      Public StaticHandler Getmainthreadhandler () { A         returnMmainthreadhandler; the     } +  -      Public StaticLooper Getmainthreadlooper () { $         returnMmainthreadlooper; $     } -  -      Public StaticThread Getmainthread () { the         returnMmainthead; -     }Wuyi  the      Public Static intGetmainthreadid () { -         returnMmaintheadid; Wu     } -  About}

Then remember to declare it in the manifest file:

 1  <  application  2  = "true"  3   Android:icon  = "@mipmap/ic_launcher"  4   Android: Label  = "@string/app_name"  5  Span style= "color: #ff0000;" > Android:theme  = "@style/apptheme"  6
       Android:name  =". MyApplication "  >  

The property that needs to be declared is the 6th line of Android:name in the code above.
