title: Can't generate APK from Android Studio
body: <p>I'm trying to generate an APK. I go to <code>Build</code> -> <code>Generate signed APK</code> and after all, I get this message:</p>
  
  <blockquote>
    <p>Error:A problem was found with the configuration of task ':app:packageRelease'.
    File 'geovanni_geopath_keystore_02' specified for property 'signingConfig.storeFile' does not exist.</p>
  </blockquote>
  
  <p>Can any one help me please? Thank you</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>This is my <code>build.gradle</code> file, I don't know what is wrong:</p>
  
  <pre><code>apply plugin: 'android'
  
  android {
      compileSdkVersion 19
      buildToolsVersion "19.1.0"
  
      defaultConfig {
          applicationId "com.example.geopath"
          minSdkVersion 14
          targetSdkVersion 19
      }
  
  
  
      buildTypes {
          release {
              runProguard false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
          }
      }
  }
  
  dependencies {
      compile 'com.android.support:support-v4:20.0.0'
      compile 'com.google.code.gson:gson:2.2.2'
      compile 'com.android.support:appcompat-v7:20.+'
      compile 'com.google.android.gms:play-services:+'
      compile files('libs/mobileservices-1.1.5-javadoc.jar')
      compile files('libs/mobileservices-1.1.5-sources.jar')
      compile files('libs/mobileservices-1.1.5.jar')
  }
