@ Andru ..... Intent FilterIntent=new Intent(AndroidTabRestaurantDescListView.this,SearchPage.class); — smriti3, Dec 26 '13 at 06:27
class SearchPage is in the project or in a jar lib? You need check the apk file whether it contains .class file for SearchPage — Ivan, Dec 26 '13 at 06:41
@ Ivan ...... class SearchPage is in the project .... i can see it in the class structure ... — smriti3, Dec 26 '13 at 06:47

12-26 11:43:06.253: E/AndroidRuntime(506): java.lang.NoClassDefFoundError: com.project.findmybuffet.SearchPage
12-26 11:43:06.253: E/AndroidRuntime(506):  at com.project.findmybuffet.AndroidTabRestaurantDescListView$3.onClick(AndroidTabRestaurantDescListView.java:101)

It is unable to find com.project.findmybuffet.SearchPage class. Please check your package name once.

<activity android:name="com.project.findmybuffet.SearchPage" >
        </activity>

You have mentioned your search page activity in this path "com.project.findmybuffet.SearchPage" so please check whether that SearchPage.class is in that path or not. If everything is good. Try clean your project and run again

Now try this

Photos.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub

                Intent photoIntent=new Intent(AndroidTabRestaurantDescListView.this,AndroidTabRestaurantDescImageListView.class);
                startActivity(photoIntent);

            }
        });


        Filter.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent filterIntent=new Intent(AndroidTabRestaurantDescListView.this,Filters.class);
                startActivity(filterIntent);
            }
        });


        Search.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent searchIntent=new Intent(AndroidTabRestaurantDescListView.this,SearchPage.class);
                startActivity(searchIntent);
            }
        });


        Account.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub

                Intent accountIntent=new Intent(AndroidTabRestaurantDescListView.this,RestaurantAccount.class);
                startActivity(accountIntent);

            }
        });

Did you try cleaning project – saa Dec 26 '13 at 06:54
Ok... close your eclipse. Copy your project. Delete this project from your workspace. Now delete following files from your project .classPath, .project, project.properties. Then import your project into workspace. You will get fresh project. – saa Dec 26 '13 at 07:01
So you will get fresh project. Import it and run it. Hopes it will work. Otherwise let me know – saa Dec 26 '13 at 07:08
