Activity crashes the app after it starts

Question

I want to run " FakeActivity " class first instead of " MainActivity " but it keeps crashing every time i run it. Can anyone please tell me why the activity is crashing every time I load it. Following is my Java code:

package com.example.android.findbar;

import android.location.Location;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class FakeActivity extends AppCompatActivity {

    /*Global variables for user's Longitude and User's Latitude*/

    EditText Longitude, Latitude;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_fake);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        Longitude = (EditText)findViewById(R.id.Longitude);
        Latitude = (EditText)findViewById(R.id.Latitude);

        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });

    }

    public void CheckLocation(View view){

        String Longi = Longitude.getText().toString();
        String Lati = Latitude.getText().toString();
        String type = "Locator";
        BackgroundWorker backgroundWorker = new BackgroundWorker(this);
        backgroundWorker.execute(type, Longi, Lati);
    }

}

then my xml file:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context="com.example.android.findbar.FakeActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

    </android.support.design.widget.AppBarLayout>

    <include layout="@layout/content_fake" />

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        android:src="@android:drawable/ic_dialog_email" />

</android.support.design.widget.CoordinatorLayout>

Answer 1

First of all, you need to check that Google Play services is available or not in your SDK. Because your crash report shows the error that "Google Play services is missing" in second line of your Logcat.

In Android Studio click: Tools > Android > SDK Manager > Launch stand alon sdk manager.

Find : Extras > Google Play Services.

if Google Play Services is not installed, than install it first and than run project again.

Answer 2

1. Replace all Longitude to longitude & all Latitude to latitude in XML file & Java File. It will fix your problem.

EditText longitude, latitude;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_fake);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    longitude = (EditText)findViewById(R.id.longitude);
    latitude = (EditText)findViewById(R.id.latitude);

2. change ids of EditText also as per above JAVA code
