Question

我执行了所有程序来添加 google maps api，但出现此错误。抱歉语言不好。

09 12:20:55.359: W/dalvikvm(5918): Unable to resolve superclass of Lmaps/a/du; (406)

01-09 12:20:55.359: W/dalvikvm(5918): VFY: unable to resolve new-instance 3566 (Lmaps/j/k;) in Lmaps/y/ae;

这是 manifest.xml

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
 <uses-permission android:name="android.permission.INTERNET" />
 <uses-permission android:name="android.permission.READ_PHONE_STATE" />
 <uses-permission android:name="com.comparto.piso.permission.MAPS_RECEIVE" />
 <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

 <permission
        android:name="com.comparto.piso.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

       <application
              ........ >
            <uses-library android:name="com.google.android.maps" />
   <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="api key" />
    ......
    .....

在 java 代码中，我扩展了 FragmentActivity，这里是 onCreate 代码

GooglePlayServicesUtil
                .isGooglePlayServicesAvailable(getApplicationContext());

        GoogleMap map = ((SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map)).getMap();
        if (map != null) {
            map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        }

这里是布局xml

 <fragment
                xmlns:android="http://schemas.android.com/apk/res/android"
                android:id="@+id/map"
                android:layout_width="fill_parent"
                android:layout_height="300px"
                class="com.google.android.gms.maps.SupportMapFragment" />

Answer 1

如果您的设备与 Google Maps 库使用的 API 级别不同，则 logcat 中来自 Dalvik 的所有“无法解析父类(super class) xxxx”和“类 xxxx 的链接失败”都是正常的。

您应该使用以下命令检查您是否获得授权失败:

adb logcat | grep Maps

如果你看到这样的东西:

E/Google Maps Android API(): Authorization failure.

那么这意味着您没有在 list 中提供正确的 API key 。再次检查您的 Google API Console (在 API 访问 部分)您是否添加了正确的指纹和包名称对作为 described in the guide .
