android - 我更新了一个应用程序但失败了。 ProGuard 中缺少类型参数

Question

我更新了一个具有几乎相同代码的应用程序，在之前的版本中我在混淆器中没有问题。当我从 AndroidStudio 启动应用程序时我没有遇到问题，但是当我在应用程序的某些部分启动已签名的应用程序时会显示此错误:

07-21 14:45:02.156  24372-24372/pe.gob.devida E/AndroidRuntime﹕ FATAL EXCEPTION: main

APIKey 存在且“Google Maps Android API v2”已启用

我认为问题出在proguard-rules.pro

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in C:\Users\Diego\AppData\Local\Android\sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:
-optimizationpasses 5
-dontusemixedcaseclassnames

-dontskipnonpubliclibraryclassmembers
-dontpreverify
-verbose

-dontwarn pe.gob.devida.**
-dontwarn org.simpleframework.**
-dontwarn com.squareup.picasso.**
-dontwarn com.parse.**
-dontwarn com.google.gsom.**

-keep public class * extends pe.gob.devida.activities.BaseActivity
-keep public class * extends pe.gob.devida.fragments.BaseFragment
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

使用Gson时BaseActivity和BaseFragment的扩展类出现错误。

当我打开这个 Fragment 时会显示日志:CentrosFragment.class

    }

                .findFragmentById(R.id.centrosMap);
        mapFragment.getMapAsync(this);
        return root;

Answer 1

我用这个解决了我的问题:

混淆器:

-renamesourcefileattribute SourceFile
-keepattributes  Signature,SourceFile,LineNumberTable
-keep public class * extends android.app.Application
