Android. OS. networkonmainthreadexception Exception Handling

Public void oncreate (bundle savedinstancestate) {// For details, see the strictmode document strictmode. setthreadpolicy (New strictmode. threadpolicy. builder (). detectdiskreads (). detectdiskwrites (). detectnetwork () // or. detectall () for all detectable problems. penaltylog (). build (); strictmode. setvmpolicy (New strictmode. vmpolicy. builder (). detectleakedsqlliteobjects (). detectleakedclosableobjects (). penaltylog (). penaltydeath (). build (); super. oncreate (savedinstancestate); setcontentview (R. layout. main); initdialog ();}

Download programs designed on Android 2.3 run on Android 4.0 and report to Android. OS. networkonmainthreadexception exception. Originally in 4.0, the access network cannot be performed in the main program. There are two solutions. One is to add the following in the main program: (I am using ftpclient. connect (string, INT) error ).

Another method is to start the thread to execute the download task (not tried ):

 

Public void oncreate (bundle savedinstancestate) {super. oncreate (savedinstancestate); setcontentview (R. layout. main); // start the thread to execute the download task new thread (downloadrun ). start ();}/*** download thread */runnable downloadrun = new runnable () {@ override public void run () {// todo auto-generated method stub updatelistview ();}};
