Here is my class:

package com.SverkerSbrg.Spendo.Graphics;

import com.SverkerSbrg.Spendo.R;
import com.SverkerSbrg.Spendo.Graphics.TransactionList.*;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;

public class SwipeMenu extends FragmentActivity {

    private ViewPager mPager;
    private PagerAdapter mPagerAdapter;

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

        mPager = (ViewPager) findViewById(R.id.pager);
        mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
        mPager.setAdapter(mPagerAdapter);
    }

    @Override
    public void onBackPressed() {
        if (mPager.getCurrentItem() == 0) {
            // If the user is currently looking at the first step, allow the
            // system to handle the
            // Back button. This calls finish() on this activity and pops the
            // back stack.
            super.onBackPressed();
        } else {
            // Otherwise, select the previous step.
            mPager.setCurrentItem(mPager.getCurrentItem() - 1);
        }
    }

    private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {

        public ScreenSlidePagerAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {
            return new TransactionList();
        }

        @Override
        public int getCount() {
            return 2;
        }
    }
}

And here is my manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.SverkerSbrg.Spendo"
    android:versionCode="1"

    <uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="17" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.SverkerSbrg.Spendo.MainActivity"
            android:label="@string/app_name" >
        </activity>
        <activity
            android:name="com.SverkerSbrg.Spendo.Menu"
            android:label="@string/title_activity_menu" >
        </activity>
        <activity
            android:name="com.SverkerSbrg.Spendo.SwipeMenu"
            android:label="@string/title_activity_swipe_menu" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

All help is greatly appreciated :)

Answer 1

On ur manifest

package="com.SverkerSbrg.Spendo"

and in ur activity class

package com.SverkerSbrg.Spendo.Graphics;

so u have to keep same name of package.
