Trying to implement CountryPicker from github. No errors in code, app crashes, a lot of logcat errors

It seems that I am asking something that has been asked in the past, but nobody else managed to get an answer for, therefore fingers crossed.

I am trying to implement the CountryPicker from github. However it doesn't seem to work. I had tried 2 out 3 possible ways to implement it (at least I think there were 3).

  1. First one was to add the CountryPicker code inside my application and on top of that implement the sample folder code (didnt work)
  2. Second one was to somehow change the fragmentactivity code to activity (havent tried that yet)
  3. Third one was to import the CountryPicker code as a library. I think that was the right way to do it, therefore I have listed the steps I have done to make it work.

  1. First I have created new android project called CountryPickerApp and implemented the code from the sample folder found within that countrypicker repository. Here's the code for MainActivity.class:

     package com.example.countrypickerapp;
     import android.os.Bundle;
     import android.support.v4.app.FragmentActivity;
     import android.support.v4.app.FragmentManager;
     import android.support.v4.app.FragmentTransaction;
     import android.view.Menu;
     import android.view.MenuItem;
     import android.view.MenuItem.OnMenuItemClickListener;
     import android.widget.Toast;
    
     import com.countrypicker.CountryPicker;
     import com.countrypicker.CountryPickerListener;
    
     public class MainActivity extends FragmentActivity {
    
      @Override
      protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    
        FragmentManager manager = getSupportFragmentManager();
        FragmentTransaction transaction = manager.beginTransaction();
    
        CountryPicker picker = new CountryPicker();
        picker.setListener(new CountryPickerListener() {
    
            @Override
            public void onSelectCountry(String name, String code) {
                Toast.makeText(
                        MainActivity.this,
                        "Country Name: " + name + " - Code: " + code
                                + " - Currency: "
                                + CountryPicker.getCurrencyCode(code),
                        Toast.LENGTH_SHORT).show();
            }
        });
    
        transaction.replace(R.id.home, picker);
    
        transaction.commit();
    
    }
    
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        MenuItem item = menu.findItem(R.id.show_dialog);
        item.setOnMenuItemClickListener(new OnMenuItemClickListener() {
    
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                CountryPicker picker = CountryPicker.newInstance("Select Country");
                picker.setListener(new CountryPickerListener() {
    
                    @Override
                    public void onSelectCountry(String name, String code) {
                        Toast.makeText(
                                MainActivity.this,
                                "Country Name: " + name + " - Code: " + code
                                        + " - Currency: "
                                        + CountryPicker.getCurrencyCode(code),
                                Toast.LENGTH_SHORT).show();
                    }
                });
    
                picker.show(getSupportFragmentManager(), "COUNTRY_PICKER");
                return false;
            }
        });
        return true;
    }
    

    }

  2. Here's the code for the AndroidManifest.xml file

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.countrypickerapp"
     android:versionCode="1"
     android:versionName="1.0" >
    
    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />
    
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
           android:name="com.example.countrypickerapp.Main1Activity"
            android:label="@string/app_name" android:parentActivityName="@string/title_activity_main1">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
    
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
           android:name="com.example.countrypickerapp.MainActivity"
           android:label="@string/title_activity_main1" >
        </activity>
    </application>
    
    </manifest>
    
  3. As far as I understood the main folder (CountryPicker) had to be imported as a library so i followed those steps:

File->New->Other
Select Android Project
Select "Create Project from existing source"
Click "Browse..." button and navigate to johannilsson-android-actionbar\actionbar
Finish (Now action bar project in your workspace)
Right-click on your project -> Properties
In Android->Library section click Add
select recently added project -> Ok
  1. And here is the list of logcat log errors:

Additonally I have added an additional Activity called MainActivity1 which has a button, which when clicked redirects to MainActivity where CountryPicker is implemented.

I hope I have explained my problem well and will get either a solution, tip, hint or anything which could get me closer to getting it to work. I know that I could have reimplemented all of it from scratch using different methods, but I don't see a point of reinventing something that has been already been implemented and uploaded for sharing, apart from learning something new of course.

Your manifest declares Main 1 Activity (space added to highlight the numeric 1) but your class file is MainActivity.java without the 1 !! :)
