package com.example.maps;

import android.app.Activity;

public class MyActivity extends Activity {

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

// main.xml

                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
</manifest>

1. 編譯-沒有錯誤
2. 運行時錯誤在那里。
3. 向庫和模塊添加了Google服務jar
4. 使用IntelliJ的想法
5. 從Google網站獲取此代碼
6. 還參考了android開發人員

以下是我的錯誤：

您只需使用以下代碼替換地圖片段

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