java.lang.RuntimeException : Unable to start activity ComponentInfo when using admob sdk

Question

我很确定这与 Theme.AppCompat 无关，因为启用 proguard 的应用程序最初在没有 com.google.android.gms:play-services- 的情况下也能正常运行ads:7.5.0，添加 com.google.android.gms:play-services-ads:7.5.0 后出现问题。

包含 com.google.android.gms:play-services-ads 后，它仅在禁用 proguard 时有效。

有人可以帮忙吗？我真的很讨厌java无法保护源代码，并且希望我永远不会使用proguard。

Admob 的 Proguard(从 gi​​thub 上的 admob 示例复制):

# For Google Play Services
-keep public class com.google.android.gms.ads.**{
   public *;
}

# For old ads classes
-keep public class com.google.ads.**{
   public *;
}

# For mediation
#-keepattributes *Annotation*

# Other required classes for Google Play Services
# Read more at http://developer.android.com/google/play-services/setup.html
-keep class * extends java.util.ListResourceBundle {
   protected Object[][] getContents();
}

-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
   public static final *** NULL;
}

-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
   @com.google.android.gms.common.annotation.KeepName *;
}

-keepnames class * implements android.os.Parcelable {
   public static final ** CREATOR;
}

Answer 1

以下是您在 admob 的 proguard 规则中需要的内容:

-keep class com.google.android.gms.common.GooglePlayServicesUtil {*;}
-keep class com.google.android.gms.ads.identifier.AdvertisingIdClient {*;}
-keep class com.google.android.gms.ads.identifier.AdvertisingIdClient$Info {*;}

-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.**
-keep class com.google.ads.** {*;}

检查是否缺少任何内容或仅添加所有内容(没有区别)，然后检查您的应用是否正常工作。

另外，您的 Activity java 文件扩展的是哪个类，如果它扩展的是 ActionBarActivity，请将其更改为 Activity。
