android - Where can be use onSaveInstanceState where parameters are passed different Activity? -

for acitivity there method called onsaveinstacestate(bundle) used store data of activity overridden method.

as see, there 2 different onsaveinstancestate parameters passed differently below.

@override     public void onsaveinstancestate(bundle outstate, persistablebundle outpersistentstate)     {         super.onsaveinstancestate(outstate, outpersistentstate);         log.i("test", "onsaveinstancestate called **********");     } 

and

@override     protected void onsaveinstancestate(bundle outstate)     {          super.onsaveinstancestate(outstate);           log.i("test", "onsaveinstancestate bundle called");     } 

so, @ circumstances 2 methods can use? please describe in detail. in advance.

from api level 21, onsaveinstancestate()has new parameter called takes object of persistablebundle. can read more persistablebundle on docs

in short,

for api 21 , above

@override     public void onsaveinstancestate(bundle outstate, persistablebundle outpersistentstate)     {         super.onsaveinstancestate(outstate, outpersistentstate);         log.i("test", "onsaveinstancestate called **********");     } 

for api less 20

@override     protected void onsaveinstancestate(bundle outstate)     {          super.onsaveinstancestate(outstate);           log.i("test", "onsaveinstancestate bundle called");     }
