google-maps-android-api-2 - java.lang.noclassdeffounderror : com. google.android.gms.R$styleable

Question

我正在使用谷歌地图创建一个Android应用程序。这是代码:

MapFragActivity.java

 import android.os.Bundle;
    import android.support.v4.app.FragmentActivity;
    import com.google.android.gms.maps.GoogleMap;
    import com.google.android.gms.maps.SupportMapFragment;

    public class MapFragActivity extends FragmentActivity {

    private GoogleMap map;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_map_frag);

        map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
                .getMap();
     }
    }

AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.him.mapfrag_rnd"
        android:versionCode="1"
        android:versionName="1.0" >

        <uses-sdk
            android:minSdkVersion="11"
            android:targetSdkVersion="15" />

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


        <application
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name"
            android:theme="@style/AppTheme" >
            <activity
                android:name=".MapFragActivity"
                android:label="@string/title_activity_map_frag" >
                <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="my_api_key" />

        </application>

    </manifest>

activity_map_frag.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >

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

    </RelativeLayout>

当我尝试此代码时，出现错误，这是日志:

当我在 MapFragActivity.java 中进行一些更改时，就会显示 map 。以下是更改:

package com.him.mapfrag_rnd;

    import android.os.Bundle;
    import android.support.v4.app.FragmentActivity;

    import com.google.android.gms.maps.SupportMapFragment;

    public class MapFragActivity extends FragmentActivity {

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            //setContentView(R.layout.activity_map_frag);
          SupportMapFragment fragment = new SupportMapFragment();
          getSupportFragmentManager().beginTransaction().add(android.R.id.content, fragment).commit();
        }
    }

我所做的更改被注释为 setContentView。我已遵循所有必需的步骤，但仍然出现错误。如果取消注释 setContentView() 然后我再次收到错误。

请帮忙!!!

Answer 1

如果您使用的是 Intellij Idea，

1. 从项目面板中选择您的项目
2. 按 F4 打开项目结构窗口
3. 从左侧面板中选择模块，然后点击 + 按钮，然后选择“导入模块”并导航至“ANDROID-SDK”/extras/google/google_play_services/libproject/google-play-services_lib。通过执行此操作，该项目将与您的项目一起添加到模块中
4. 选择您的项目，然后从右侧面板中选择“依赖项”(它是一个选项卡)。点击“+”按钮，然后点击“3 Module dependency...”并选择“google-play-services_lib”。
5. 再次点击“+”按钮，然后点击“1 jars ordirectories...”，导航到上述路径中的“/libs”文件夹，然后选择“google-play-services.jar”。
6. 单击“确定”并关闭项目结构窗口。

注意:确保您尚未将“google-play-services_lib”项目添加为“库”(模块下的左侧面板)中的库。如果有，您可以转到“库”并将其删除。Google Play 库不应出现在库中。

注 2:如果您希望将整个 google-play-services_lib 目录纳入版本控制或类似项目，您可以将其复制到您自己的项目中。
