Activity B starts before Activity A

Question

I was trying to get a small image to show up before my Main Activity starts. This is my current coding in the android manifest

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <activity
            android:name=".Splash"
            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=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="com.example.test.MAINACTIVITY" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
    </application>

whatever I do, my splash screen does not start. They start separately, but never together, (I still haven't put a timer in my splash image as I want to check whether it works or not and it isn't working)

may be your splash screen starts then immediately navigates to MainActivity so you don't see the change. put a delay and then give it a try — Raghunandan, Sep 30 '13 at 14:57
`package com.example.test; import android.app.Activity; import android.os.Bundle; public class Splash extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.splash); } }` This is the current code for splash, do you require the XML code as well?. I've checked a tutorial which shows the exact same thing, but in his case, the application stops at the splash screen! — user2831076, Sep 30 '13 at 15:02
@user2831076 you can start new activity from Splash class. **startActivity(new Intent(Splash.this, MainActivity.class));** **finish();** — Kanwaljit Singh, Sep 30 '13 at 15:14
@user2831076 i updated your splash class. now this works fine. i am sure. try this. — Kanwaljit Singh, Oct 01 '13 at 08:36

Remove

<intent-filter>
    <action android:name="com.example.test.MAINACTIVITY" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

Use below code in splash screen after desired time

Intent intent=new Intent(this,MAINACTIVITY.class);
startActivity(intent);
finish();  //To close splashscreen when MAINACTIVITY loads

The above code starts with splash screen and after some time start your main activity

the first block is to remove from the Manifest file you provided in your post, the second block is to add to the java file defining your Splash activity , you should add it in the onCreate, after waiting for a timer to finish – Tourki Sep 30 '13 at 15:09
this didn't do it either! I'm not sure what to do now! I've tried following exactly what the tutorial showed, and yet mine does not work! – user2831076 Sep 30 '13 at 15:35
I copied the entire code as is and it still doesn't work! Should I try doing the entire thing from scratch again? – user2831076 Sep 30 '13 at 15:51

You should remove the <intent-filter> section from your MainActivity declaration ,
and launch the MainActivity from the splashActivity using a simple intent and startActivity call.

Try this.

        <activity
            android:name=".Splash"
            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=".MainActivity" >
        </activity>
    </application>

Code for your Splash Class-

package com.example.test;
import android.app.Activity; 
import android.os.Bundle; 
public class Splash extends Activity 
{ 
@Override 
protected void onCreate(Bundle savedInstanceState) 
{ // TODO Auto-generated method stub 
super.onCreate(savedInstanceState); 
setContentView(R.layout.splash); 

final Handler handle = new Handler();
Runnable delay = new Runnable() {
public void run() {
startActivity(new Intent(Splash.this, MainActivity.class));
                finish();
            }
        };
        handle.postDelayed(delay,5000);
} 
}

its delay next intent 5 second. you can set time according to you.

the same thing, it just doesn't show the splash screen and directly goes to MainActivity — user2831076, Sep 30 '13 at 15:44

Use This:

<activity
        android:name=".Splash"
        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=".MainActivity" >
    </activity>
</application>

and This :

public class Splash extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);

    final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        public void run() {
            Intent mInHome = new Intent(Splash.this, MainActivity.class);
            Splash.this.startActivity(mInHome);
            Splash.this.finish();
        }
    }, 3000);
}
}

Activity B starts before Activity A
