You are doing a few things wrong as you probably didn't follow all the steps in using Google Maps on your application:
Google Maps API key is supposed to be inside of the application tags in your manifest.
You are missing the play services meta tag (also inside the application tags):
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
Also make sure that you are compiling the play services with your project. If you're using Android-Studio, then the bottom of your build.gradle file should look like this:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:20.+'
compile 'com.google.android.gms:play-services:5.0.77'
}

Android Application crahes when passing strings between classes

I'm trying to pass a string between 2 classes in Android . The first class is "MainActivity" and the second one is "abc" .
Here's my MainActivity code :

import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
public class MainActivity extends ActionBarActivity {
String pass;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pass = "abcabc";
Intent abc = new Intent(this , abc.class);

If I remove "startActivity(abc);" the application doesn't crash, also if use try&catch the application doesn't crash but the same time it doesn't perform the action . So what could be the reason ? and thanks in advance

and my Manifest after the update :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

You need to add your second Activity to your Androidmanifest.xml file.
<activity android:name="com.example.passstrings.abc" />

have you declared this activity in your AndroidManifest.xml?
04-04 05:34:38.685: E/AndroidRuntime(734): at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java:1404)
it clearly say's that you have not declared your abc activity in manifest file. have you declared this activity in your AndroidManifest.xml?
so just decalre your abc activity in manifest file.
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.passstrings.MainActivity"
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>
</application>
add this line
<activity
android:name=".abc"
</activity>
and also change this in your abc.java
setContentView(R.layout.activity_main);
you have reference of activity_main only you have to set abc.XML or whatever your XML filename for abc. So change it with
setContentView(R.layout.abc);
Edit
public class abc extends Activity{
TextView tv1;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
tv1=(TextView) findViewById(R.id.textView1);
Intent intent = getIntent();
String pass= intent.getExtras().getString("key");
if(pass!= null){
tv1.setText(pass);
}
}

It is simply ActivityNotFoundException which mean you forgot to declare abc activity in your AndroidManifest.xml file.
Just add following line in your manifest.xml in application tag.
<activity android:name="com.example.passstrings.abc" />
For your new NullPointerException here is the solution
You have defined following .xml in your Activity file activity_main while you have declare TextViews in fragment_main.xml, that's why it is giving NullPointerException.
I suggest you to change the xml from following line
setContentView(R.layout.activity_main);
to
setContentView(R.layout.fragment_main.xml);

You can't change the map options in onCreate, as it has not yet been instantiated. Try doing all of the stuff in OnLocationChanged to your GoogleMap object in onResume() instead of onCreate().

Cant get my app to work. Just crashes

I'm trying to learn to build Android apps. This is my very first attempt. Everything was okay and when I would get to this activity (this is when someone would select rock) I could have it display Hello World. I tried to develop rules for winning and losing but whenever I select rock my app just crashes. Please take a look.

Android Java: Global variables through subclass; can't launch app?

I've been reading up examples on how to do this, trying to piece together a functioning example from posts on this site and others. I'm sure I'm missing something small, but as a novice to Java, I could use some assistance.
I'm merely trying to create a small example, derived from the automated hello world generated when creating a new project in Eclipse. All I want to do is be able to store a few global variables in a subclass, then reference those values in my main activity. Unfortunately, every time I try to run the app, it crashes "Unfortunately, GeneralTest1 has stopped", and the log cat error is not very helpful.
Quick overview:
GlobalVars class extends Application
In the manifest, android:name has been added to reference the additional GlobalVars class
Within my main activity, I'm initializing the global vars class with getApplicationContext()
Here is everything I've got; any help would be much appreciated!
MainActivity.java
package com.example.generaltest1;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.TextView;
public class MainActivity extends Activity {
GlobalVars myVars = ((GlobalVars)getApplicationContext());
TextView myText = (TextView) findViewById(R.id.myText);
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myText.setText(myVars.getMyString());
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
GlobalVars.java
package com.example.generaltest1;
import android.app.Application;
public class GlobalVars extends Application {
String myString = "Some Text";
public String getMyString() {
return myString;
}
public String setMyString(String string) {
this.myString = string;
return myString;
}
}

You are calling getApplicationContext() in your class definition, which is too early in the activity lifetime and results in a nullpointer exception. Move the assignments to your onCreate() function and it should work as expected.

Please check this article about activities and their lifecycle :
http://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle
Your activity should look like this:
public class MainActivity extends Activity {
GlobalVars myVars;
TextView myText;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myVars = ((GlobalVars)getApplication());
myText = (TextView) findViewById(R.id.myText);
myText.setText(myVars.getMyString());
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}

Add these lines in oncreate()..
GlobalVars myVars = ((GlobalVars)getApplicationContext());
TextView myText = (TextView) findViewById(R.id.myText);
