Question

升级到Google Play服务v23后，我在尝试在Eclipse中导出已签名的应用程序时看到此消息：

Proguard returned with error code 1. See console
Warning: com.google.android.gms.common.GooglePlayServicesUtil: can't find referenced class android.content.pm.PackageInstaller

我按照documentation

中的说明添加了此内容

-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;
}

并尝试添加

-keep class android.content.pm.PackageInstaller.**

到proguard-project.txt，但这并没有帮助。

我错过了什么？

Answer 1

嘿，我有完全相同的错误，我通过添加：

修复它

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

到我的proguard.cfg

Answer 2

我遇到了同样的问题，但使用Android Studio。基于Lary Ciminera的解决方案，我添加了

-dontwarn com.google.android.gms.**

到proguard-project.txt。

Answer 3

我通过将它添加到proguard-project.txt：

来修复它

-keep class android.content.pm.PackageInstaller
-keep class android.content.pm.PackageInstaller$SessionInfo
-keep class android.content.pm.PackageManager

-dontwarn android.content.pm.PackageInstaller
-dontwarn android.content.pm.PackageInstaller$SessionInfo
-dontwarn android.content.pm.PackageManager

-keep class android.webkit.WebSettings
-dontwarn android.webkit.WebSettings

Answer 4

将目标SDK版本升级到至少21可以解决此问题。 API版本21中添加了PackageInstaller和关联的类：https://developer.android.com/reference/android/content/pm/PackageInstaller.html
