Android Studio安装失败，APK未签名 [英] Installation failed with Android Studio, APK not signed

问题描述

最近从Eclipse转到Android Studio，我也将JDK从 java-open-jdk 更改为 jdk1.7.0_45 。

现在我正在尝试运行我的第一个应用程序，并收到以下消息：

安装由于APK未签名或签名不正确，因此失败。 
如果这是一个基于Gradle的项目，那么确保在Gradle构建脚本中指定了签名配置
 

编辑：

当我从Android Studio运行时，出现上面显示的错误。当我从命令行运行它时，我没有收到错误（该应用程序正在运行，并且出现错误，但与Gradle无关）。

我从这里获得了代码

您可以在 google repo

UPDATE 2 ：

我添加了这段代码

  signingConfigs { 
发布{
 storeFile文件（john.keystore）
 storePasswordjohn
 keyAliasjohnkeystore
 keyPasswordjohn
} 
 
 $ / code> 

就在 buildTypes 代码之上阻止build.gradle文件。
文件john.keystore位于我的项目的根目录下。我正在运行 gradlew assembleRelease ，我得到了一个 xxx-release-unsigned.apk 。

解决方案

如果确实使用gradle运行构建，则需要配置 signingConfigs 。 Android可以自动配置您的调试signingConfig。您可以通过下列方式发布 signingConfig ：



  android {
 
 signingConfigs {
 
发布{
 
 storeFile文件（'android.keystore'）
 storePasswordpwd
 keyAlias别名
 keyPasswordpwd

} 
 
 buildTypes {
 
版本{
 
 signingConfig signingConfigs .release 
} 
} 
}

如果您仍有问题，请更新问题与您的 build.gradle 。最可能的问题是铺设在这里。我使用的JDK 1.7和gradle builds工作正常。

Recently change to Android Studio from Eclipse and I have also changed the JDK from java-open-jdk to jdk1.7.0_45.

Now I'm trying to run my first app and I get this message:

Installation failed since the APK was either not signed, or signed incorrectly.
If this is a Gradle-based project, then make sure the signing configuration 
is specified in the Gradle build script

Edit:

When I'm running from Android Studio I get the error displayed above. When I'm running it from the command line I don't get an error (well the app is running and I get an error but nothing to do with gradle).

I got the code from here

You can check build.gradle here at google repo

UPDATE 2:

I added this code

signingConfigs {
    release {
        storeFile file("john.keystore")
        storePassword "john"
        keyAlias "johnkeystore"
        keyPassword "john"
    }
}

just above the buildTypes code block in the build.gradle file. File john.keystore is on the root of my Project. I'm running gradlew assembleRelease and I'm getting a xxx-release-unsigned.apk.

解决方案

If you indeed runing build with gradle you need to configure signingConfigs. Android can configure your debug signingConfig automatically. You can make release signingConfig in a next manner:

android {

    signingConfigs {

        release {

            storeFile file('android.keystore')
            storePassword "pwd"
            keyAlias "alias"
            keyPassword "pwd"
        }
    }

    buildTypes {

       release {

           signingConfig signingConfigs.release
       }
    }
}

If you still have issues, please update question with your build.gradle. Most likely issue is laying here. I'm using JDK 1.7 and gradle builds are working fine.
