android noclassdeffoound error

Question

This is my splash screen activity im trying to display a particular image for a period of time and when it is supposed to go to the second class it gives me an error as no classdeffounderror

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layoutt1);
mSplashThread = new Thread() {
        @Override
        public void run() {

            try {
                while (shouldContinue) {

                    synchronized (this) {
                        // Wait given period of time or exit on touch
                        wait(5000);
                        shouldContinue = false;

                    }
                }
            } catch (InterruptedException ex) {
            } finally {
                finish();

                // Run next activity
                Intent intent = new Intent(getApplicationContext(),MainActivity.class);
                startActivity(intent);
                shouldContinue = false;

                // stop();
            }

        }
    };

    mSplashThread.start();

}

My logcat shows

06-10 14:38:00.450: E/AndroidRuntime(5853): java.lang.NoClassDefFoundError: com.bara.fol.MainActivity

Could not find class 'com.bara.fol.MainActivity', referenced from method com.bara.fol.Main$1.run

and this is my manifest.xml present inside the application tag.

    <activity
        android:name=".Main"
        android:label="@string/title_activity_main" >
        <intent-filter
            android:label="@string/app_name"
            >
            <action android:name="android.intent.action.MAIN" />

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

are you using any IDE , i means laoutt1 , with double T thats correct right ?? — Hussain Akhtar Wahid 'Ghouri', Jun 10 '13 at 09:18
is your code going to the intent?? because in code you have written finish before launching the intent!! — skygeek, Jun 10 '13 at 09:31

First of all you are using finish before start intent, it should be written after startintent call and as you said you are using a library follow these steps and clean your project:

project right click properties-> Java BuildPath select Library and add external .jar the follow these step.

Go to Project->Properties->Java Build Path than select Order and export tab. Set external .jar library checked and up it into top of the list. And clean and rebuild.

Try Following code for splash screen...It's work for me

new Handler().postDelayed(new Runnable() 

        {
            @Override
            public void run() 
            {
                final Intent mainIntent = new Intent(StartActivity.this, SecondActivity.class);
                StartActivity.this.startActivity(mainIntent);
                StartActivity.this.finish();
            }
        }, 1000);

I think you did not declare the Activity in the manifest.xml.

In the manifest, you have declared ".Main" instead of ".MainActivity"
