无法使用proguard生成已签名的apk

问题描述:

当我尝试生成已启用proguard的已签名apk时,出现以下错误。无法使用proguard生成已签名的apk

Error:Uncaught translation error: com.android.dx.cf.code.SimException: com.android.dx.rop.cst.CstMethodRef cannot be cast to com.android.dx.rop.cst.CstInterfaceMethodRef 
Possible causes for this unexpected error include:<ul><li>Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) 
<a href="syncProject">Re-download dependencies and sync project (requires network)</a></li><li>The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem. 
<a href="stopGradleDaemons">Stop Gradle build processes (requires restart)</a></li><li>Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.</li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes. 

这是我使用了/做什么:

  1. 的Android Studio 2.2中
  2. 播放服务版本9.6.1
  3. proguard-rules.pro

    • dontwarn okio.
    • dontwarn retrofit2.Platform$Java8
    • keep public class com.google.android.gms.
    • dontwarn com.google.android.gms.
    • keepattributes InnerClasses,EnclosingMethod
  4. gradle这个(APP)

    defaultConfig { 
        applicationId "com.something.something" 
        minSdkVersion 15 
        targetSdkVersion 23 
        versionCode 3 
        versionName "3.0" 
    
        // Enabling multidex support. 
        multiDexEnabled true 
    
        testInstrumentationRunner "com.android.test.runner.MultiDexTestRunner" 
    } 
    buildTypes { 
        release { 
         minifyEnabled true 
         proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
        } 
    } 
    productFlavors { 
    } 
    
  5. 库,我使用的是:

    • com.radiusnetworks:proximitykit-android:[email protected]
    • com.squareup.retrofit2:retrofit:2.0.2
    • com.google.firebase:firebase-messaging:9.6.1

从这个SO answer基础,下面的代码应该工作,只要你不需要任何特殊的ProGuard配置。

buildTypes { 
    release { 
     minifyEnabled true 
     proguardFiles getDefaultProguardFile('proguard-android.txt') 
    } 
} 

如果这样做,使用原来的proguardFiles条目并创建该文件/Users/franek/Documents/Android_Studio_Melange/app/proguard-rules.txt然后把您的自定义规则,在这个文件中。

thread也可能有所帮助。将以下行添加到proguard-rules.pro文件中,以解决使用Proguard (Minify Enabled = true)无法生成已签名APK的问题。

保持类org.apache.http。**
保持类android.net.http。**
dontwarn com.google.android.gms。**

我曾经到设置minifyEnabled = false为我的工作! – Eenvincible
