我的谷歌地图 v2 测试应用程序崩溃

Question

我是 stackoverflow 的新手 我有使用的谷歌地图测试项目 here 我喜欢教程，但应用程序崩溃了。

我完成了教程中的每一个步骤，并获得了 android 密钥、添加的库等等： 我的类似问题是这个链接： here 但它没有任何有效的答案。 我完全删除了 eclips，卸载了 java JDK 和 JRE，甚至我的整个系统 java。但应用程序崩溃了。 任何机构都可以帮助我吗？非常感谢

这是我的代码：

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

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.NavUtils;



public class MainActivity extends FragmentActivity {

     private GoogleMap googleMap;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        try {
            // Loading map
            initilizeMap();

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

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

    private void initilizeMap() {
        if (googleMap == null) {

            //googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

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

            // check if map is created successfully or not
            if (googleMap == null) {
                Toast.makeText(getApplicationContext(),
                        "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                        .show();
            }
        }
    }
}

清单文件是：

    android:versionCode="1"
    android:versionName="1.0" >

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

    </application>

            <!-- Goolge API Key -->

            android:value="AIzaSyBYju6h2BWvZOaSDQpe5f9tv6fJsZy6cY8" />

</manifest>

布局是：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

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

</RelativeLayout>

这是 logcat：

Answer 1

改变

public class MainActivity extends FragmentActivity {

到

public class MainActivity extends Activity {

改变这个

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

到

googleMap =   ((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();

您还需要清单中的应用程序标记中的以下内容

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

这是 google play services rev 13 的要求

编辑：

移动

 <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSyBYju6h2BWvZOaSDQpe5f9tv6fJsZy6cY8" />

清单中的应用程序标签内

Answer 2

试试这个。

你的 MainActivity

private void initilizeMap() {
    if (googleMap == null) {
        googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
        // Valida si el mapa no se creo correctamente
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(), "Sorry! el mapa no pudo ser cargado", Toast.LENGTH_SHORT)
                    .show();
        }
    }
}

在你的布局中

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

在清单中，我在 MAC 中使用了这一行，因为在 Windows 中没有它们也能正常工作

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

Answer 3

我也有类似的问题。对我来说：

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

并将 xml 更改为

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

解决了这个问题。希望你也解决！
