Question

我正在尝试在我的应用中使用谷歌地图，我在应用程序中使用谷歌播放服务

MapViewActivity：

public class MapsViewActivity extends FragmentActivity {
// Google Map
private GoogleMap googleMap;

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

    try {
        // Loading map
        initilizeMap();

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

}

/**
 * function to load map. If map is not created it will create it for you
 * */
private void initilizeMap() {
    if (googleMap == null) {
        googleMap = ((MapFragment) getFragmentManager().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();
        }
    }
}

XML：

<?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" />

并收到以下错误：

我没有得到我错了或遗失任何东西的地方如何删除请帮我解决这个问题。

Answer 1

显然，从您的logcat开始，您只需复制粘贴的manifest.xml文件。您必须输入密钥，而不是您的API密钥

从Google控制台生成密钥。并在manifest.xml中使用它

googlemap版本2需要两个元数据

一个使用 api密钥，另一个使用 google服务

android:value="@integer/google_play_services_version"

所以你应该简单地复制粘贴线。而且只能稍后试着。： - ）

<强>编辑：

将包名更改为您的（不是androidhive :-)）更改权限

中的行

<permission
    android:name="info.androidhive.googlemapsv2.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

要：

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

另外，为什么在uses-permission中使用 info.androidhive.googlemapsv2 的包名称。将其更改为您自己的包名称，即 com.example.careandcure 。希望它最终成为你的解决方案。

Answer 2

日志说你：

 Caused by: java.lang.RuntimeException: API key not found.  Check that <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml

所以请确保您在AndroidManifest.xml中添加它，就像在guide中一样：

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

Answer 3

在您的清单文件错误导致此行

<!-- Goolge Maps API Key -->
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="my api key" />

在API密钥的值中，您必须添加自己的API密钥。

请参阅此link以获取生成API密钥

错误Api密钥未找到
