android - Cannot acces ActivityCompatApi23 when trying to use FragmentActivity -


i'm trying use viewpager on smartwatch, keep getting error when trying rebuild/run/debug application. i'm using fragmentactivity, error occurs. searched stackoverflow , tutorial websites see problem, , lot of results related build.gradle files. tried pretty stumbled upon, error didn't change once.

the error:

error: cannot acces activitycompatapi23

the error happens on line, coming piece of code below.

public class wearmainactivity extends fragmentactivity {

wearmainactivity.java

package be.ehb.dt.finalwork_lievenluyckx_v001;  import android.os.bundle; import android.support.v4.app.fragment; import android.support.v4.app.fragmentactivity; import android.support.v4.view.pageradapter; import android.support.v4.view.viewpager;  import java.util.list; import java.util.vector;  /**  * created lieven on 14/08/17.  */  public class wearmainactivity extends fragmentactivity {       private pageradapter pageradapter;      /* (non-javadoc)       * @see android.support.v4.app.fragmentactivity#oncreate(android.os.bundle)       */     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         super.setcontentview(r.layout.viewpager);         //initialsie pager         initialisepaging();     }      /**      * initialise fragments paged      */     private void initialisepaging() {          list<fragment> fragments = new vector<fragment>();         fragments.add(fragment.instantiate(this, monitor.class.getname()));         fragments.add(fragment.instantiate(this, currentsongoverviewwear.class.getname()));         this.pageradapter  = new mypageradapter(getsupportfragmentmanager(), fragments);          viewpager pager = (viewpager) findviewbyid(r.id.viewpager_container);         pager.setadapter(this.pageradapter);     } }

build.gradle (wear)

apply plugin: 'com.android.application'  android {     allprojects {         repositories {             jcenter()             maven {                 url "https://maven.google.com"             }         }     }      compilesdkversion 25     buildtoolsversion "25.0.1"     defaultconfig {         applicationid "be.ehb.dt.finalwork_lievenluyckx_v001"         minsdkversion 25         targetsdkversion 25         versioncode 1         versionname "1.0"      }     buildtypes {         release {             minifyenabled false             proguardfiles getdefaultproguardfile('proguard-android.txt'), 'proguard-rules.pro'         }     }  }  dependencies {     compile 'com.android.support:wear:26.0.0'     compile 'com.android.support:appcompat-v7:25.1.1'     compile 'com.google.android.support:wearable:2.0.3'     compile 'com.google.android.gms:play-services:11.0.4'     provided 'com.google.android.wearable:wearable:2.0.3'     compile 'com.android.support:support-v4:26.0.0-alpha1' }

i experienced similar issue when using appcompatactivity:

error: cannot access activitycompatapi23

i fixed setting specific support library version:

compile 'com.android.support:appcompat-v7:26.+' <-- old compile 'com.android.support:appcompat-v7:26.0.2' <-- new

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...

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() .
