Question

我不会说英语，但是......

我正在制作一款使用GMaps v2的Android应用。一切都处于调试模式，但是当我在发布应用程序中午餐时，地图代码不会执行！

我确定发布的apiKey设置得很好（我在src / release / values / google_maps_api.xml中设置它并且apiKey没有限制），因为如果我在发布构建类型中设置minifyEnabled = false ，它有效！所以我认为这是proguard的一个问题......

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，控制台不会返回任何异常

地图初始化位于片段中：

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？至少我必须找到问题...

谢谢！

    Note that this file specifies the API key for the release build target.
    If you have previously set up a key for the debug target with the debug signing certificate,
    you will also need to set up a key for your release certificate.

    Follow the directions here:

Answer 1

必须在AndroidManifest.xml中明确设置Google地图的API密钥才能生效。

对于调试模式，可以在google_maps_api.xml中设置但是对于发布版本，它必须在AndroidManifest.xml中

E.g。

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

我这样做时通常会创建两个键。一个用于调试，一个用于发布。这是必要的，因为调试的SHA对于发布是不同的，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发布到调试时，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>"/>

Answer 2

嗯，问题不在gmaps中，而是在我使用的materialtabs库中（https://github.com/neokree/MaterialTabs），现在我使用https://github.com/ogaclejapan/SmartTabLayout并且它完美无缺！

Android gmaps无法使用minifyEnabled = true ... apiKey已设置
