Android 地图不适用于 minifyEnabled = true...已设置 apiKey

Question

我不会说英语，但是...

我正在制作一个使用 GMaps v2 的 android 应用程序。在调试模式下一切都很好，但是当我午餐发布应用程序时，地图代码不执行！

我确定发布的 apiKey 设置得很好（我在 src/release/values/google_maps_api.xml 中设置并且 apiKey 没有限制），因为如果我设置 minifyEnabled = false在发布构建类型中，它有效！，所以我认为这是混淆器的问题...

我尝试了下一个 proguard 规则的所有组合，但没有...

-keep class com.google.** {*;}

-keep class com.hawk.angela.home.activities.MapFragment { *; }


-keep class com.google.android.gms.maps.** { *; }
-keep interface com.google.android.gms.maps.** { *; }

-keep class * extends java.util.ListResourceBundle { protected Object[][] getContents(); }
-keepattributes InnerClasses
-dontoptimize

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Fragment
-keep public class * extends android.support.v4.app.Fragment

# The Maps API uses custom Parcelables.
# Use this rule (which is slightly broader than the standard recommended one)
# to avoid obfuscating them.
-keepclassmembers class * implements android.os.Parcelable {
    static *** CREATOR;
}

# The Maps API uses serialization.
-keepclassmembers class * implements java.io.Serializable {
    static final long serialVersionUID;
    static final java.io.ObjectStreamField[] serialPersistentFields;
    private void writeObject(java.io.ObjectOutputStream);
    private void readObject(java.io.ObjectInputStream);
    java.lang.Object writeReplace();
    java.lang.Object readResolve();
}

此外，控制台return没有任何异常

地图初始化在片段中：

MapView mapView = (MapView) rootView.findViewById(R.id.mapView);
Bundle mapState = (savedInstanceState != null) ?
        savedInstanceState.getBundle("mapState") :
        null;
mapView.onCreate(mapState);
mapView.onResume(); // needed to get the map to display immediately

mapView.getMapAsync(new OnMapReadyCallback() {
    @Override
    public void onMapReady(GoogleMap mMap) {
        googleMap = mMap;
        googleMap.setMaxZoomPreference(maxZoom);

        // ...
    }
});

有人能帮帮我吗？至少我必须在哪里找到问题...

谢谢！！

Google 地图的 API 键必须在 AndroidManifest.xml 中明确设置才能工作。

对于调试模式，它可以在 google_maps_api.xml 中设置，但对于发布版本，它必须在 AndroidManifest.xml

中

例如

<meta-data
            android:name="com.google.android.geo.API_KEY"
            android:value="<your API key here>"/>

我通常会在执行此操作时创建两个密钥。一个用于调试，一个用于发布。这是必要的，因为用于调试的 SHA 与发布版本不同，因此您需要为每个创建两个单独的 API 密钥。

所以我的 AndroidManifest.xml 看起来有点像下面的那个。当我将构建从调试转移到发布或从发布转移到调试时，我只是取消注释元数据。

    <!-- Development/Debug Google Maps API Key -->
    <!--<meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="@string/google_maps_key"/> -->

    <!-- Release Google Maps API Key -->
    <meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="<my API key here>"/>

好吧，问题不在 gmaps 中，而是在我使用的 materialtabs 库中（https://github.com/neokree/MaterialTabs), now I use https://github.com/ogaclejapan/SmartTabLayout，它工作得很好！

Android 地图不适用于 minifyEnabled = true...已设置 apiKey

Android gmaps doesnt work with minifyEnabled = true... apiKey are setted
