android - activity main MAIN and LAUNCHER is not fired first -
i have launcher activity followed loginactivity. everytime start app loginactivity fired first rather launcheractivity. xml manifest.xml like
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.kryptapps.konel.dchat2" > <application android:allowbackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:theme="@style/customtheme" > <activity android:name=".launcheractivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.main" /> <category android:name="android.intent.category.launcher" /> </intent-filter> </activity> <activity android:name=".loginactivity" android:label="@string/title_activity_login" > </activity> <activity android:name=".grouplistactivity" android:label="@string/title_activity_group_list" > </activity> </application> </manifest> java file :
public class launcheractivity extends activity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_launcher); loadpersonaldatas(); thread time = new thread() { public void run() { try { sleep(20000); } catch (interruptedexception e) { e.printstacktrace(); } } }; time.start(); } void loadpersonaldatas(){ new thread() { public void run() { try { sleep(500); } catch (interruptedexception e) { e.printstacktrace(); } } }.start(); intent intent = new intent(this, loginactivity.class); startactivity(intent); } @override protected void onpause() { super.onpause(); finish(); } } the login activity usual log in page.
actually launcheractivity getting fired, 500 milliseconds.
whats happening wait 20000 milliseconds , execution of loadpersonaldatas() carried out simultaneously.
but after 500 milliseconds, activity changes , sleep(20000) interrupted.
for loginactivity launch after 20000 milliseconds, should start loginactivity after sleep(20000) in run() method.
public class launcheractivity extends activity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_launcher); thread time = new thread() { public void run() { try { sleep(20000); loadpersonaldatas(); //start activity here } catch (interruptedexception e) { e.printstacktrace(); } } }; time.start(); } void loadpersonaldatas(){ new thread() { public void run() { try { sleep(500); } catch (interruptedexception e) { e.printstacktrace(); } } }.start(); intent intent = new intent(this, loginactivity.class); startactivity(intent); } @override protected void onpause() { super.onpause(); finish(); } } now, loginactivity start after 20500 milliseconds.
