title: INSTALL_PARSE_FAILED_NO_CERTIFICATES with OWN .apk
body: <p>Since I updated my Android Studio, I cant install my App anymore, neither in the debug nor in the release mode.</p>
  
  <p>I always get the error:</p>
  
  <pre><code>pkg: /data/local/tmp/com.myappdomain.mypp
  </code></pre>
  
  <p>Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]</p>
  
  <p>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.
  Error while Installing APK</p>
  
  <p>From what I googled, this just happens when trying to install unsigned third party .apk
  This is my own App though, signed with Android Studio</p>
  
  <p>Gradle looks like this:</p>
  
  <pre><code>android {
      signingConfigs {
          release {
              storeFile file("...")
              keyAlias "..."
              storePassword "..."
              keyPassword "..."
          }
      }
      buildTypes {
          release {
              minifyEnabled true
              zipAlignEnabled true
              signingConfig signingConfigs.release
          }
      }
      compileSdkVersion 22
      buildToolsVersion "21.1.2"
      defaultConfig {
          applicationId '...'
          minSdkVersion 14
          targetSdkVersion 22
      }
      productFlavors {
      }
  }
  </code></pre>
