This is a procedure to configure run release version  1- Change build variants to release version     2- Open project structure    3- Change default config to  signingConfigs release

open the Build Variants pane  typically found along the lower left side of the window       set debug to release shift f10 run     then  Android Studio will execute assembleRelease task and install xx-release apk to your device

in the latest version of android studio  you can just do     gradlew assembleRelease   or aR for short   This will produce an unsigned release apk   Building a signed apk can be done similarly or you can use Build -  Generate Signed Apk in Android Studio   See the docs here  Here is my build gradle for reference   buildscript     repositories       mavenCentral         dependencies       classpath  com android tools build gradle 0 5          apply plugin   android   dependencies     compile fileTree dir   libs   include     jar      android   compileSdkVersion 17 buildToolsVersion  17 0 0   sourceSets       main           manifest srcFile  AndroidManifest xml          java srcDirs     src           resources srcDirs     src           aidl srcDirs     src           renderscript srcDirs     src           res srcDirs     res           assets srcDirs     assets                 Move the tests to tests java  tests res  etc        instrumentTest setRoot  tests           Move the build types to build-types  lt type gt         For instance  build-types debug java  build-types debug AndroidManifest xml             This moves them out of them default location under src  lt type gt      which would        conflict with src  being used by the main source set         Adding new build types or product flavors should be accompanied        by a similar customization      debug setRoot  build-types debug       release setRoot  build-types release       buildTypes       release

To activate the installRelease task  you simply need a signingConfig  That is all   From http   tools android com tech-docs new-build-system user-guide TOC-Android-tasks      Finally  the plugin creates install uninstall tasks for all build   types  debug  release  test   as long as they can be installed  which   requires signing     Here is what you want   Install tasks ------------- installDebug - Installs the Debug build installDebugTest - Installs the Test build for the Debug build installRelease - Installs the Release build uninstallAll - Uninstall all applications  uninstallDebug - Uninstalls the Debug build uninstallDebugTest - Uninstalls the Test build for the Debug build uninstallRelease - Uninstalls the Release build    lt --- release   Here is how to obtain the installRelease task   Example build gradle   buildscript       repositories           jcenter              dependencies           classpath  com android tools build gradle 1 2 3           apply plugin   com android application   android     compileSdkVersion 22   buildToolsVersion  22 0 1     defaultConfig       applicationId  demo      minSdkVersion 15     targetSdkVersion 22     versionCode 1     versionName  1 0         signingConfigs         release             storeFile  lt file gt            storePassword  lt password gt            keyAlias  lt alias gt            keyPassword  lt password gt                 buildTypes       release           signingConfig signingConfigs release
