Question

我是Android开发的新手，但我还在学习并创建了一些简单活动的应用程序。但是这个需要我进行谷歌地图服务活动的应用程序无法由我执行。请查看代码并解释任何错误。我非常感谢你。

这里是清单代码

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="com.example.googlemaps.permission.MAPS_RECEIVE" />

<uses-sdk
    android:minSdkVersion="12"
    android:targetSdkVersion="18" />

<permission
  android:name="com.example.googlemaps.permission.MAPS_RECEIVE"
  android:protectionLevel="signature" />

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

<uses-feature
  android:glEsVersion="0x00020000"
  android:required="true" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <activity
        android:name="in.csbuddy.aaas.Aaas"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <uses-library android:name="com.google.android.maps" />
    <meta-data
     android:name="com.google.android.maps.v2.API_KEY"
     android:value="AIzaSyAJJlKWPyQmwjfua1HV0fVHVkbN4Ny_iaw" />
</application>

和java代码

package in.csbuddy.aaas;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;

public class Aaas extends Activity {
  static final LatLng HAMBURG = new LatLng(53.558, 9.927);
  static final LatLng KIEL = new LatLng(53.551, 9.993);
  private GoogleMap map;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout_aaas);
    map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
        .getMap();
    Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
        .title("Hamburg"));
    Marker kiel = map.addMarker(new MarkerOptions()
        .position(KIEL)
        .title("Kiel")
        .snippet("Kiel is cool")
        .icon(BitmapDescriptorFactory
            .fromResource(R.drawable.ic_launcher)));

    // Move the camera instantly to hamburg with a zoom of 15.
    map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));

    // Zoom in, animating the camera.
    map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
  }

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.aaas, menu);
    return true;
  }

}

，布局文件如下：

<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"
    tools:context=".MainActivity" >

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

</RelativeLayout>

logcat的：

每当我尝试跑步时，该应用程序都不会打开并显示＆＃34;不幸的是......＆＃34;错误。请帮帮我。

您需要在清单文件中添加以下内容。

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

同样在您的build.gradle for app中，您需要添加以下依赖项。

dependencies {
compile 'com.google.android.gms:play-services:7.8.0'
}

您也可以参考this post获取更多帮助！

希望这可以解决问题。
