java - android anonymous asyncTask - will it cause memory leak -


in android trying prevent memory leak. inherited legacy code , in developer creating asynctask anonymous inner class this:

 void startasynctask() {     new asynctask<void, void, void>() {         @override protected void doinbackground(void... params) {             while(true);//loop  keep thread alive forever.         }     }.execute(); }

so using loop in example keep child thread alive forever can demo point. activity if call startasynctask() there memory leak ? class not have activity reference realize anonymous class non-static inner class , holds reference outer class. true memory leak ?

it hold reference outer class (the activity) until task finishes. cause activity held longer absolutely necessary. if task finishes in reasonable amount of time, ought ok- after finished task on , become garbage collectable, make activity garbage collectable. bigger concern long term threads can last past end of activity, or not terminate @ if poorly written.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
