NB   Now instead of   runProguard false   you ll need to use   minifyEnabled false

Try renaming your  proguard-rules txt  file to  proguard-android txt  and remove the reference to  proguard-rules txt  in your gradle file  The getDefaultProguardFile      call references a different default proguard file  one provided by Google and not that in your project  So remove this as well  so that here the gradle file reads   buildTypes       release           runProguard true         proguardFile  proguard-android txt

You re probably not actually signing the release build of the APK via the signing wizard  You can either build the release APK from the command line with the command     gradlew assembleRelease   or you can choose the release variant from the Build Variants view and build it from the GUI

You can configure your build gradle file for proguard implementation  It can be at module level or the project level    buildTypes        debug           minifyEnabled false         proguardFiles getDefaultProguardFile  proguard-android txt     proguard-rules txt              The configuration shown is for debug level but you can write you own build flavors like shown below inside buildTypes       myproductionbuild          minifyEnabled true         proguardFiles getDefaultProguardFile  proguard-android txt     proguard-rules txt          Better to have your debug with minifyEnabled false and productionbuild and other builds as minifyEnabled true   Copy your proguard-rules txt file in the root of your module or project folder like   YOUR PROJECT DIR YoutProject yourmodule proguard-rules txt  You can change the name of your file as you want  After configuration use one of the three options available to generate your build as per the buildType   Go to gradle task in right panel and search for assembleRelease assemble  your defined buildtype  under module tasks Go to Build Variant in Left Panel and select the build from drop down Go to project root directory in File Explorer and open cmd terminal and run    Linux   gradlew assembleRelease or assemble  your defined buildtype   Windows  gradlew assembleRelease  or  assemble  your defined buildtype   You can find apk in your module build directory   More about the configuration and proguard files location is available at the link  http   tools android com tech-docs new-build-system user-guide TOC-Running-ProGuard

The other answers here are great references on using proguard  However  I haven t seen an issue discussed that I ran into that was a mind bender  After you generate a signed release  apk  it s put in the  release folder in your app but my app had an apk that wasn t in the  release folder  Hence  I spent hours decompiling the wrong apk wondering why my proguard changes were having no affect  Hope this helps someone
