java - Why Dialer app opens Contacts app - Android Studio custom launcher -


i've built custom launcher android, have issue on samsung phone. when try open dialer app opens samsung's contact app. on emulator works fine, think problem on phone. how can fix it?

this code set packages in main activity.

public void setpackages(){     final intent mainintent = new intent(intent.action_main, null);     mainintent.addcategory(intent.category_launcher);     list<resolveinfo> packageslist = packagemanager.queryintentactivities(mainintent, 0);     packages = new package[packageslist.size()];     (int = 0; < packageslist.size(); i++){         packages[i] = new package(packageslist.get(i).loadicon(packagemanager), packageslist.get(i).loadlabel(packagemanager).tostring());         packages[i].seticon(packageslist.get(i).loadicon(packagemanager));         packages[i].setappname(packageslist.get(i).activityinfo.packagename);         packages[i].setlabel(packageslist.get(i).loadlabel(packagemanager).tostring());     }     new utils().changesort(packages);     draweradapter = new draweradapter(this, packages);     gridview.setadapter(draweradapter);     gridview.setnumcolumns(sharedpreferences.getint("drawer_grid_columns", 4));     gridview.setonitemclicklistener(new drawerclicklistener(this, packages, packagemanager, gridview)); }

this custom gridview adapter.

public class draweradapter extends baseadapter {  context mcontext; package[] packforadapter;   public draweradapter(context context, package pack[]){     mcontext = context;     packforadapter = pack; }  @override public int getcount() {     return packforadapter.length; }  @override public object getitem(int i) {     return null; }  @override public long getitemid(int i) {     return 0; }  static class viewholder{     textview labeltext;     imageview iconimage; }  @override public view getview(int i, view view, viewgroup viewgroup) {     viewholder viewholder;     layoutinflater layoutinflater = (layoutinflater) mcontext.getsystemservice(context.layout_inflater_service);     sharedpreferences sharedpreferences= preferencemanager.getdefaultsharedpreferences(mcontext);     float iconsize = 0, labelsize = 0;     if (sharedpreferences.getint("drawer_grid_columns", 4) == 4){         iconsize = mcontext.getresources().getdimension(r.dimen.icon_app_size_4);     } else if (sharedpreferences.getint("drawer_grid_columns", 4) == 5){         iconsize = mcontext.getresources().getdimension(r.dimen.icon_app_size_5);     } else if (sharedpreferences.getint("drawer_grid_columns", 4) == 6){         iconsize = mcontext.getresources().getdimension(r.dimen.icon_app_size_6);     }     labelsize = mcontext.getresources().getdimension(r.dimen.label_app_size);     if (view == null){         view = layoutinflater.inflate(r.layout.drawer_grid_item, null);         viewholder = new viewholder();         viewholder.labeltext = (textview) view.findviewbyid(r.id.label_text);         viewholder.iconimage = (imageview) view.findviewbyid(r.id.icon_image);         view.settag(viewholder);     } else {         viewholder = (viewholder) view.gettag();     }      viewholder.iconimage.setimagedrawable(packforadapter[i].geticon());     viewholder.iconimage.getlayoutparams().height = (int)iconsize;     viewholder.iconimage.getlayoutparams().width = (int)iconsize;     viewholder.labeltext.settext(packforadapter[i].getlabel());     viewholder.labeltext.settextsize(labelsize);     return view; }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
