Anmeldung und Anzeige einer Karte funktioniert auf Emulator aber stürzt auf Telefon

Question

Ich bin neu in der Android-Entwicklung und versuche, eine App zu erstellen, mit der sich jemand anmelden und eine Google Map später anzeigen kann. Die App scheint auf dem Android Studio ADB-Emulator zu funktionieren, aber ich bin mir nicht ganz sicher, weil du keine Google Map auf dem Emulator anzeigen kannst. Aber wenn ich die App auf meinem Samsung S3 installiere, stürzt es ab, nachdem ich mich angemeldet habe. Hier

ist der Code für das Login (Ich bin mit Feuerbasis):

@Override protected void onCreate (Bundle savedInstanceState) { super.onCreate (savedInstanceState);

setContentView(R.layout.activity_login); 
    // Set up the login form. 


    mEmailView = (AutoCompleteTextView) findViewById(R.id.email); 
    populateAutoComplete(); 

    mPasswordView = (EditText) findViewById(R.id.password); 
    mPasswordView.setOnEditorActionListener(new TextView.OnEditorActionListener() { 
     @Override 
     public boolean onEditorAction(TextView textView, int id, KeyEvent keyEvent) { 
      if (id == R.id.login || id == EditorInfo.IME_NULL) { 
       attemptLogin(); 
       return true; 
      } 
      return false; 
     } 
    }); 

    Button mEmailSignInButton = (Button) findViewById(R.id.email_sign_in_button); 
    mEmailSignInButton.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      attemptLogin(); 
     } 
    }); 

    mLoginFormView = findViewById(R.id.login_form); 
    mProgressView = findViewById(R.id.login_progress); 
    Firebase.setAndroidContext(this); 
} 

private void registerUser(String email, String password) { 
    Firebase mFirebaseRef = new Firebase("https://shining-fire-3472.firebaseio.com/users/"); 
    User newuser = new User(email, password); 

    mFirebaseRef.push().setValue(newuser); 

    Intent intent = new Intent(LoginActivity.this, LogedIn.class); 
    //intent.putExtra("passingEmail", newuser.getEmail()); 
    //intent.putExtra("passingPass", newuser.getPassword()); 
    startActivity(intent); 

private void signInUser(String email, String password) { 
    //boolean varifyingEmail = varifyEmail(email); 
    //if (varifyingEmail == true) { 
    Firebase ref = new Firebase("https://shining-fire-3472.firebaseio.com/users/"); 
    Query queryRef = ref.orderByChild("email").equalTo(email); 

    queryRef.addListenerForSingleValueEvent(new ValueEventListener() { 
     @Override 
     public void onDataChange(DataSnapshot dataSnapshot) { 
      for (DataSnapshot userSnapshot : dataSnapshot.getChildren()) { 
       User user = userSnapshot.getValue(User.class); 


       Intent intent = new Intent(LoginActivity.this, LogedIn.class); 
       //intent.putExtra("passingEmail", user.getEmail()); 
       //intent.putExtra("passingPass", user.getPassword()); 
       startActivity(intent); 
      } 
     } 

ich ein Fragment der Karte bin mit der Karte in einer XML-Datei anzuzeigen:

<?xml version="1.0" encoding="utf-8"?> 
<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="ca.maciorowski.maciorowski.railapp.LogedIn"> 


<fragment 
    android:name="com.google.android.gms.maps.MapFragment" 
    android:id="@+id/map" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"/> 
</RelativeLayout> 

Dies ist logcat:
