Android version downgrade

Add the following two sentences to the android program: to downgrade the version, you must add

Strictmode. setthreadpolicy (New strictmode. threadpolicy. Builder (). detectdiskreads (). detectdiskwrites (). detectnetwork (). penaltylog (). Build ());
Strictmode. setvmpolicy (New strictmode. vmpolicy. Builder (). detectleakedsqlliteobjects (). penaltylog (). penaltydeath (). Build ());

Location: The oncreat method is as follows:

For example:

Public class tidsdemoactivity extends activity {
//
Private edittext medittext_show = NULL;
Private button mbotton_serversocket = NULL;
Private button mbutton_socket = NULL;
Private socket msocket = NULL;
Private serversocket mserversocket = NULL;
Private string mstring = "";
Private bufferedreader mbufferedreader = NULL;
@ Override
Protected void oncreate (bundle savedinstancestate ){
// Todo auto-generated method stub
// Downgrade the version
/* Strictmode. setthreadpolicy (New strictmode. threadpolicy. Builder (). detectdiskreads (). detectdiskwrites (). detectnetwork (). penaltylog (). Build ());
Strictmode. setvmpolicy (New strictmode. vmpolicy. Builder (). detectleakedsqlliteobjects (). penaltylog (). penaltydeath (). Build ());*/
Super. oncreate (savedinstancestate );
This. setcontentview (R. layout. Main );
