Splash screen crash when change in android manifest

Question

My splash screen ( splash.java ) works fine , it appear for 5 sec when I call it Launcher in Android Manifest , but when i fix it as Default in Android Manifest and run it through List Activity ( Menu.java ) , it run for 5sec and then instead of going back to Menu.java it crashes with run time error . I want it to appear for 5 sec and then go back to the menu.java.

The manifest in which it not work for 5 sec but application crash run time after 5 sec (Unfortunately your application has stopped)

<activity
    android:name=".Menu"
    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=".splash"
    android:label="@string/app_name" >
    <intent-filter>
        <action android:name="com.example.hello.SPLASH" />

        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>

This splash.java

protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity2);
        tone = MediaPlayer.create(splash.this, R.raw.songg);
        tone.start();
        Thread haai = new Thread()
        {
            public void run()
            {
                try
                {
                    sleep(5000);
                }
                catch (InterruptedException e)
                {
                    e.printStackTrace();
                }
                finally 
                {
                    Intent first = new Intent("com.example.hello.Menu");
                    startActivity(first);
                }
            }       
        };
        haai.start();
    }

Error log:

I am not satisfied with my own answer because i am in learning stage so waiting for better answer with explanation of its working and problem.

Answer 1

ActivityNotFoundException: No

Because not Activity found with com.example.hello.MENU action in manifest.

To fix issue,use com.example.hello.MENU action string for Menu Activity. like:

<activity
    android:name=".Menu"
    android:label="@string/app_name" >
    <intent-filter>
        <action android:name="com.example.hello.MENU" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

Or you can start Activity using target Activity class name :

Intent intent=new Intent (splash.this,Menu.class);
splash.this.startActivity(intent);

Answer 2

The problem is in the manifest you have set the activity name .Menu whereas in the java code you have set it as MENU(uppercase).

<activity
    android:name=".Menu" <---- activity name as .Menu
    android:label="@string/app_name" >

In java code as:

Intent first = new Intent("com.example.hello.MENU")<---.MENU- its all uppercase

Change it in java code as below to fix your problem:

Intent first = new Intent("com.example.hello.Menu");
startActivity(first);

Answer 3

I find the answer , its simple but I use the other way but still I don't find why the program works fine when .splash make as Main and LAUNCHER , but when make .Menu as Main and LAUNCHER program run but when I select splash from Menu List it run for 5 seconds then instead of going back to Menu again it crashes with runtime error . I changed the .splash code to the below code and it works but as I am new to android I don't know why the last way was not working.

public void run()
            {
                try
                {
                    sleep(5000);
                }
                catch (InterruptedException e)
                {
                    e.printStackTrace();
                }
                finally 
                {
                    try
                    {
                    Class ourclass = Class.forName("com.example.hello.Menu");
                    Intent myclass = new Intent(splash.this , ourclass);
                    startActivity(myclass);
                    }
                    catch(ClassNotFoundException e)
                    {
                        e.printStackTrace();
                    }

                }
            }       

I didn't change anything from Android Manifest

Answer 4

The problem is you declared intent action is .SPLASH but you create action is .MENU
change

Intent first = new Intent("com.example.hello.MENU");
                   startActivity(first);

to

Intent first = new Intent("com.example.hello.SPALSH");
                   startActivity(first);

or change your manifest like 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=".Menu"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.example.hello.MENU" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
