Answer 1

Please change Below in AndroidManifest.xml

 <activity android:name=".abc" android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
 </activity>

also add below line

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

then try it.

Answer 2

Did you correctly register abc.class as an Activity in your AndroidManifest.xml file? That would cause a crash.

<activity android:name="com.something.something.abc" android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.ABC" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
 </activity>
<activity android:name="something.package.something.xyz" android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.XYZ" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
 </activity>

public class ListItemIntent extends Activity implements OnItemClickListener {   
    ListView lv1;
    String[] names = { "Abc", "Xyz", "Pqr", "Jap", "Jay", "Blabla" };

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        lv1 = (ListView) findViewById(R.id.list);
        lv1.setAdapter(new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, names));
        lv1.setOnItemClickListener(this);
    }

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
        Intent intent;
        switch (arg2) {
            case 0:
                intent= new Intent(this,Abc.class);
                startActivity(intent);
                break;
            case 1:
                intent=new Intent(this,Xyz.class);
                startActivity(intent);
                break;
            case 2:
                intent=new Intent(this,Pqr.class);
                startActivity(intent);  
                break;
            case 3:
                intent=new Intent(this,Jap.class);
                startActivity(intent);      
                break;
            case 4:
                intent=new Intent(this,Jay.class);
                startActivity(intent);          
                break;
            case 5:
                intent=new Intent(this,Blabla.class);
                startActivity(intent);          
                break;  
            default:
                break;
        }       
    }
}

for each class you have to add Activity in Androidmanifest.xml . and manifest like..

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".ListItemIntent"
              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="Abc"></activity>
    <activity android:name="Blabla"></activity>
    <activity android:name="Jap"></activity>
    <activity android:name="Jay"></activity>
    <activity android:name="Pqr"></activity>
    <activity android:name="Xyz"></activity>
</application>
