Android的工作室无法解决getDefaultProguardFile [英] Android Studio cannot resolve getDefaultProguardFile

问题描述

当我运行我的程序我没有得到任何的问题。当我尝试生成APK签约，据我所知，getDefaultProguardFile不能得到解决。我怎样才能解决这个问题。这里是code。

 应用插件：'com.android.application安卓{
    compileSdkVersion 21
    buildToolsVersion21.1.2    defaultConfig {
        的applicationIDcom.dose.apps.brainnoodles
        8的minSdkVersion
        targetSdkVersion 21
        版本code 13
        的versionName2.13
    }
    buildTypes {
        发布 {
            //应用插件：观念
            minifyEnabled真
            proguardFiles getDefaultProguardFile（'proguard的-android.txt'），'proguard-rules.pro
        }
    }
}依赖{
    编译文件树（导演：'库'，包括：['的* .jar']）
    编译com.android.support:appcompat-v7:22.0.0
    编译文件（库/的InMobi-4.5.3.jar'）
}
 

下面是有人问堆栈跟踪

解决方案

我有同样的问题。请注意，在日志中，他们都指向你去<一个href=\"http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedlibraryclassmember\">http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedlibraryclassmember有这样说的：

  

如果你正在为Android和ProGuard的开发抱怨说，它不能
  发现，仅在最近版本的方法
  Android的运行时间，你应该改变的构建目标在
  project.properties文件或文件的build.gradle到最新版本。
  你还可以指定不同的minSdkVersion和不同
  targetSdkVersion在AndroidManifest.xml文件。

我改变了 compileSdkVersion ＆安培; targetSdkVersion 21至22和它的工作。

When I run my program i get no problems. When I try to generate signed apk, I am told that getDefaultProguardFile cannot be resolved. How can I fix this. Here is the code.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.dose.apps.brainnoodles"
        minSdkVersion 8
        targetSdkVersion 21
        versionCode 13
        versionName "2.13"
    }
    buildTypes {
        release {
            //apply plugin: 'idea'
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile files('libs/InMobi-4.5.3.jar')
}

Here's the stacktrace that was asked

解决方案

I had the same problem. Note that in the log they are pointing you to go to http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedlibraryclassmember and there it says:

If you're developing for Android and ProGuard complains that it can't find a method that is only available in a recent version of the Android run-time, you should change the build target in your project.properties file or build.gradle file to that recent version. You can still specify a different minSdkVersion and a different targetSdkVersion in your AndroidManifest.xml file.

I changed the compileSdkVersion & targetSdkVersion from 21 to 22 and it worked.
