如何使Google Maps处于混乱状态?

问题描述

我已经在我的应用程序中实现了Google Maps(Google API).因此，我在应用程序中添加了ProGuard文件.添加Proguard文件后，地图没有打开，并显示了白色的空白屏幕.

I have implemented Google Maps (Google API) in my application. So I added ProGuard file inside my application. After adding the Proguard file, the map is not opening, and showing a white blank screen.

这是我的Proguard代码:

This is my Proguard code:

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

我已经尝试过了，但是没有用.

I have tried this, but it's not working.

推荐答案

Google Maps API还使用其他一些东西，这些东西可能会在混淆过程中引起问题，例如自定义Parcelables和序列化.这些规则应该起作用:

The Google Maps API uses some other stuff as well which can cause problems during obfuscation, like custom Parcelables and serialization. These rules should work:

-keepclassmembers class * implements android.os.Parcelable {
    static *** CREATOR;
}

-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();
}

根据评论中的@Fakher:

According to @Fakher in the comments:

还请注意，您的API密钥必须正确，如果您请求了API密钥并将其添加到应用程序中，则Google仅向您显示可见的地图.

Also note that your API key needs to be correct, Google only show you a visible Map if you have requested an API key and added it in your application.
