java - Same activity getting stacked -
i have activity suppose finish , close application. now, in cases, varying on how user navigating activity, activity getting stacked. when activity stacking up, calling finish() or android.os.process.killprocess(android.os.process.mypid()); or both showing same activity again.
the manifest:
<activity android:name="newactivities.homeactivity" android:label="@string/title_activity_home" android:screenorientation="portrait"> </activity> the activity:
public class homeactivity extends activity { private edittext studentnameedittext; private button startyourstorybutton, loginbutton, navcollegesbutton, settingsbutton, search_friends_button, browsestoriesbutton; private textview textview1; @override protected void oncreate(bundle savedinstancestate){ super.oncreate(savedinstancestate); setcontentview(r.layout.activity_home); // if (getfrompreference("loginstatus").equalsignorecase("true")) { // finish(); // saveinpreference("loginstatus", ""); // } // set action bar actionbar bar = getactionbar(); bar.setbackgrounddrawable(new colordrawable(color.parsecolor("#009945"))); bar.settitle("study story"); bar.seticon(r.drawable.statusbar_icon); int titleid = getresources().getidentifier("action_bar_title", "id", "android"); textview yourtextview = (textview) findviewbyid(titleid); yourtextview.settextcolor(getresources().getcolor(r.color.white_colour)); yourtextview.settypeface(typefacecontroller.titleface(homeactivity.this)); // studentnameedittext = (edittext) // findviewbyid(r.id.studentnameedittext); startyourstorybutton = (button) findviewbyid(r.id.startyourstorybutton); // loginbutton = (button) findviewbyid(r.id.loginbutton); navcollegesbutton = (button) findviewbyid(r.id.navcollegesbutton); // settingsbutton = (button) findviewbyid(r.id.settingsbutton); // search_friends_button = (button) // findviewbyid(r.id.search_friends_button);

sharedpreferences preferences = preferencemanager.getdefaultsharedpreferences(this); preference_return = preferences.getstring(variable_name, ""); return preference_return; } } please tell me going wrong? why activity stacking?
p.s: cannot use single top etc causes transition issues existing custom theme!
take 1 application class extends application , take 1 arraylist , maintain references of activities in arraylist.
when click on button in desired activity finish activities using arraylist.
take 1 base activity. super class of activities
public class baseactviity extends activity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); app application = (app) getapplication(); application.addactivity(this); } } take 1 application class public class app extends application { public app() { if (listactivty == null) { listactivty = new arraylist<baseactviity>(); } } public arraylist<baseactviity> listactivty; public void addactivity(baseactviity actviity) { if (!listactivty.contains(actviity)) { listactivty.add(actviity); } } } take 4 samples activity classes ...... 1) public class firstactivity extends baseactviity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.first); } public void send(view view) { intent intent = new intent(this, secondactivity.class); startactivity(intent); } } 2) public class secondactivity extends baseactviity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.first); } public void send(view view) { intent intent = new intent(this, thirdactivity.class); startactivity(intent); } } 3)......................... 4) ............................ in 4 th activity class placed following code in desire activity means final activity,override onbackpressed public void onbackpressed() { super.onbackpressed(); app application = (app) getapplication(); arraylist<baseactviity> listactivty = application.listactivty; (baseactviity actviity : listactivty) { actviity.finish(); } }
