Google play services

Question

Я пытаюсь проверить google play services, но это дает ошибку. Вот мой файл манифеста.

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.gmapapp" 
    android:versionCode="1" 
    android:versionName="1.0" > 

    <uses-sdk 
     android:minSdkVersion="8" 
     android:targetSdkVersion="18" /> 

    <permission

    <uses-feature

    <application

     android:label="@string/app_name" 
     android:theme="@style/AppTheme" > 
     <activity 
      android:name="com.example.gmapapp.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> 

     <meta-data 
      android:name="com.google.android.maps.v2.API_KEY" 
      android:value="GOOGLE_API_KEY"/> 

    </application> 

</manifest> 

Вот моя основная деятельность.

public class MainActivity extends Activity { 

    private static final int GPS_ERRORDIALOG_REQUEST = 9001; 
    GoogleMap mMap; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     if (servicesOK()) { 
      Toast.makeText(this, "Google play services successfully connected.", Toast.LENGTH_SHORT).show(); 
     } 
     setContentView(R.layout.activity_main); 
    } 


    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 

    public boolean servicesOK(){ 
     int isAvailable = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this); 
     if (isAvailable == ConnectionResult.SUCCESS) { 
      return true; 
     }else if (GooglePlayServicesUtil.isUserRecoverableError(isAvailable)) { 
      Dialog dialog = GooglePlayServicesUtil.getErrorDialog(isAvailable, this, GPS_ERRORDIALOG_REQUEST); 
      dialog.show(); 
     }else{ 
      Toast.makeText(this, "Can't connect to google play services.", Toast.LENGTH_SHORT).show(); 
     } 
     return false; 
    } 

}

Answer 1

Добавьте следующую строку в ваш AndroidManifest.xml, в <application> тэгом:

<meta-data android:name="com.google.android.gms.version" 
      android:value="@integer/google_play_services_version" /> 

Бревно на самом деле довольно толковый.

Answer 2

Ваш журнал кот только ясно говорил, что:

java.lang.IllegalStateException: Тег мета-данные в AndroidManifest.xml вашего приложения не имеет правильное значение. Ожидаемое 4242000, но нашел 0. Вы должны иметь следующее заявление внутри элемента приложения:

<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> 

так что вы просто добавить его в элемент приложения в манифесте Android.
