Google Maps API v2 pour Android "Malheureusement, [l'application] s'est arrêtée."

Question

Je viens de commencer à apprendre Android. Plein de ma journée, j'essaie d'utiliser Google Map sur Android, mais chaque fois que je l'exécute sur Emulator, il donne la notification de "Malheureusement, a arrêté." Voici mon code: 1. Manifest:

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.mapmapmap"

    </application> 
</manifest> 

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?> 
<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/map" 
android:name="com.google.android.gms.maps.MapFragment" 
android:layout_width="match_parent" 
android:layout_height="match_parent" /> 

MainActivity.java:

package com.example.mapmapmap; 
import android.os.Bundle; 
import android.app.Activity; 

public class MainActivity extends Activity { 

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    } 
} 

LogCat:

J'apprécie grandement toute tentative d'aide!

Answer 1

Votre erreur suggère que vous avez modifié manuellement le chemin de génération de votre projet pour référencer un fichier JAR. Cela représenterait deux erreurs:

1. Ne jamais modifier manuellement le chemin de la construction d'une application standard Android projet

2. Le SDK Services Play est un projet de bibliothèque Android, non seulement un JAR

Vous trouverez les instructions pour attacher le SDK Play Services à votre projet au the Play Services SDK documentation.

Answer 2
