in some cases it s the best practice in other it s not a good idea it s context driven if you chose to do so using the following is the best way to pass from an activity to her sons        Intent i   new Intent myCurrentActivityName this activityIWishToRun class           startActivityForResult i  GlobalDataStore STATIC INTEGER VALUE     the thing is whenever you finish   from activityIWishToRun you return to your a living  activity

Android includes a process management system which handles the creation and destruction of activities which largely negates any benefit you d see from manually restarting an activity  You can see more information about it at Application Fundamentals  What is good practice though is to ensure that your onPause and onStop methods release any resources which you don t need to hold on to and use onLowMemory to reduce your activities needs to the absolute minimum

Reloading your whole activity may be a heavy task  Just put the part of code that has to be refreshed in  kotlin    override fun onResume         super onResume         here        Java    Override public void onResume        super onResume          here         And call  onResume    whenever needed

After experimenting with this for a while I ve found no unexpected consequences of restarting an activity  Also  I believe this is very similar to what Android does by default when the orientation changes  so I don t see a reason not to do it in a similar circumstance

This is what I do to reload the activity after changing returning from a preference change    Override protected void onResume         super onResume       this onCreate null       This essentially causes the activity to redraw itself   Updated   A better way to do this is to call the recreate   method   This will cause the activity to be recreated

In an activity you can call recreate   to  recreate  the activity  API 11

I saw earlier answers which have been given for reloading the activity using Intent  Those will work but you can also do the same using recreate   method given in Activity class itself   Instead of writing this     Refresh main activity upon close of dialog box  Intent refresh   new Intent this  clsMainUIActivity class   startActivity refresh   this finish      This can be done by writing this only  recreate

I don t think that s a good idea    it d be better to implement a cleaner method  For instance  if your activity holds a form  the cleaner method could just clear each widget in the form and delete all temporary data  I guess that s what you want  restore the activity to its initial state

After login I had the same problem so I used   Override protected void onRestart         this recreate        super onRestart

User · Answer

i used this and it works fine without  finish    startActivity getIntent

User · Answer

for those who don t want to see that blink after recreate   method simply use   finish     overridePendingTransition 0  0    startActivity getIntent      overridePendingTransition 0  0

I had another approach like  setting the launchMode of my activity to singleTop and without calling finish    just startActivity getIntent    will do the job  Just have to care about the new data both in onCreate   and onNewIntent  With Sush s way  the application may blink like AMAN SINGH said  But AMAN SINGH s approach will still create a new activity which is somehow  unnecessary  even if he fixed the  blink  problem  I think   Too late for this question  but if someone looking for a solution  here it is
