我是 android 的新手，我正在尝试在我的应用程序中使用 Google map ，使用 google play 服务时出现错误。

map View Activity :

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();
        }
    }

map .xml:

<?xml version="1.0" encoding="utf-8"?>

并出现以下错误:

我没有得到我错的地方或遗漏任何东西以及如何删除请帮助我解决这个问题。提前致谢。

最佳答案

您的元数据标签位于 标签内。删除并将其放在应用程序标签之后:

<application
android:allowBackup="true"
android:icon="@drawable/logo"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSyBOhdOOMI_ZMYlvSyi7DVeRe_bo9ckxehM" />
    <meta-data
        android:name="android.app.searchable"
        android:resource="@layout/searchable" />
<activity>//not activity tags

关于android - 元数据标签没有正确的值，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25154392/
