i am failing to run app on phone

Can you post the build.gradle file?

where do i get that file jason?

here it is:

apply plugin: 'com.android.application'

android { compileSdkVersion 21 buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "kayg.funfacts"
    minSdkVersion 14
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

}

dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:appcompat-v7:22.0.0' }

how do i do that, i have just created a github account

hello jason, this morning i tried cleaning my project and i succeeded, and i managed to run it on my phone, thanks to you but now i am facing a minor problem, its displaying only one fun fact, when i click next fact, its displaying nothing, only the layout colors are changing, probably meaning that my colorwheel is working fine, but my factbook is not

here is my layout code

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".FunfactsActivity" android:background="#ff51fffa" android:id="@+id/relativeLayout">

<TextView android:text="DID YOU KNOW?" android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:textColor="#801220ff"
    android:textColorHint="#ff70f0ff"
    android:textSize="30sp"
    android:id="@+id/txtqsn" />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="ants strecth when they wake up in the morning"
    android:id="@+id/txtfact"
    android:layout_centerVertical="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:textColor="#ff1117ff"
    android:textSize="25sp" />

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Next fun fact"
    android:id="@+id/btnnext"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:textSize="24sp"
    android:textColor="#ff1826ff" />

</RelativeLayout>

and here is my factbook code

package kayg.funfacts;

import java.util.Random;

/**

• Created by kgwaindepi on 4/11/2015. */ public class FactBook {

  //member variables public String[] mFacts = { "Ants stretch when they wake up in the morning.", "Ostriches can run faster than horses.", "Olympic gold medals are actually made mostly of silver.", "You are born with 300 bones; by the time you are an adult you will have 206.", "It takes about 8 minutes for light from the Sun to reach Earth.", "Some bamboo plants can grow almost a meter in just one day.", "The state of Florida is bigger than England.", "Some penguins can leap 2-3 meters out of the water.", "On average, it takes 66 days to form a new habit.", "Mammoths still walked the earth when the Great Pyramid was being built." };

  public String getFact () {

  String fact = "";
  //randomly select a fact
  Random randomGenerator = new Random();// construct a new random number generator
  int randomnumber = randomGenerator.nextInt(mFacts.length);
  fact = mFacts[randomnumber];
  return  fact;
  

  } //abilities or method

}

here it is

package kayg.funfacts;

import android.graphics.Color; import android.support.v7.app.ActionBarActivity; import android.os.Bundle; import android.util.Log; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.widget.Button; import android.widget.ExpandableListView; import android.widget.RelativeLayout; import android.widget.TextView; import android.widget.Toast;

import java.util.Random;

public class FunfactsActivity extends ActionBarActivity { public static final String TAG = FunfactsActivity.class.getSimpleName(); private FactBook mFactbook = new FactBook(); private ColorWheel mColorWheel = new ColorWheel();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_funfacts);
    /*declare our view variables and assign them their views*/
    final TextView txtfact = (TextView) findViewById(R.id.txtfact);
    final Button btnnext = (Button) findViewById(R.id.btnnext);

    final RelativeLayout relativeLayout = (RelativeLayout)findViewById(R.id.relativeLayout);

    View.OnClickListener listener = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String fact = mFactbook.getFact();
            int color = mColorWheel.getColor();
            relativeLayout.setBackgroundColor(color);
            btnnext.setTextColor(color);









            //update the label with our dynamic fact
            txtfact.setText("");



        }
    };

    btnnext.setOnClickListener(listener);

    Toast.makeText(this, "Activity created!", Toast.LENGTH_LONG).show();
    Log.d(TAG, "we are logging from the OnCreate() method");

}

}

you'r a genius bro, thank you so much, it just worked

i also figured out that this works also

txtfact.setText(fact); since i had declared my String fact to mFactBook.getFact()
