android - How to generate signed and unsigned APK's using gradle? -

i need generate both unsigned , signed release apks using gradle command line (gradlew assemblerelease command im using now)

the apks must aligned. checked this: build unsigned apk gradle seems old way achieve this, not work , has changed in lastest versions of android , gradle compilation. , need generate both apks @ same time, not release mode or unsigned mode

i think buildtypes more suitable place productflavors.
can extend release build replacing signingconfig.

buildtypes {     release {         ....         signingconfig signingconfigs.release     }      releaseunsigned.initwith(buildtypes.release)     releaseunsigned {         signingconfig null     } } 

then building both apk-files:

./gradlew assemble 

or if want release builds

./gradlew assemblerelease assemblereleaseunsigned or ./gradlew assr assru 

if want use assemblerelease task, can make dependency

assemblerelease.dependson assemblereleaseunsigned 

and build just

./gradlew assemblerelease
