在 android 的 eclipse 中创建 apk 时出现 proguard 异常

Question

在我的应用程序中，我想为此启用 proguard，我添加了 proguard.config=proguard.cfg 在 project.properties 中。

我的 proguard.cfg 包含

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-dontwarn javax.management.**
-dontwarn java.lang.management.**
-dontwarn org.apache.log4j.**
-dontwarn org.apache.commons.logging.**
-dontwarn org.slf4j.**
-dontwarn org.json.*
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService
-keep class javax.** { *; }
-keep class org.** { *; }
-keep class twitter4j.** { *; }

-keepclasseswithmembernames class * {
    native <methods>; }

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet); }

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int); }

-keepclassmembers class * extends android.app.Activity {    public void *(android.view.View); }

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String); }

-keep class * implements android.os.Parcelable {   public static final android.os.Parcelable$Creator *; }

我的控制台：

    please help me how to solve this issue

Answer 1

您没有在 proguard 中添加 twitter4j 的设置。您应该添加以下设置

-dontwarn javax.management.**
-dontwarn java.lang.management.**
-dontwarn org.apache.log4j.**
-dontwarn org.apache.commons.logging.**
-dontwarn org.slf4j.**
-dontwarn org.json.*

还有这个：

-keep class javax.** { *; }
-keep class org.** { *; }
-keep class twitter4j.** { *; }

这将解决您的问题

Answer 2

我遇到了同样的错误，但我的问题已通过在我的“proguard-android.txt”文件中添加以下行来解决。

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

-dontwarn org.mortbay.**
-dontwarn org.slf4j.**
-dontwarn org.apache.log4j.**
-dontwarn org.apache.commons.logging.**
-dontwarn org.apache.commons.codec.binary.**

-keep class twitter4j.** { *; }

对于 Google play 服务，如警告：com.google.android.gms.common.GooglePlayServicesUtil: can't find referenced class android.content.pm.PackageInstaller

这就是解决方案！希望它也对你有用！
