For security reasons  you cannot install an unsigned apk on Android  So if you only have the unsigned apk  you must sign it  Here is how to do that   link  Note that you can sign the apk with a self-signed certificate   An alternative can be either     to download the signed apk if available  to download the sources  compile them  with Android-Studio or gradle or       It will  produce multiple apks and one of them will be signed with your debug-key  and so you will be able to install it

The app project you downloaded may include a signed info in the file of build gradle  If you saw codes like these   buildTypes       debug           signingConfig signingConfigs release           release           signingConfig signingConfigs release           you could delete them and try again

My solution was to change the name of my signing config from the default  config  to  debug   To verify  I changed it to some other random name and got the error again  and then changed it back to  debug  and the error was gone  So while it seems artificial and I tend to not believe this is the whole story  give this solution a try

signingConfigs  should be before  buildTypes   signingConfigs           debug               storeFile file  debug keystore                      myConfig               storeFile file  other keystore               storePassword  android              keyAlias  androidotherkey              keyPassword  android                       buildTypes           bar               debuggable true             jniDebugBuild true             signingConfig signingConfigs debug                   foo               debuggable false             jniDebugBuild false             signingConfig signingConfigs myConfig

What finally worked for me  and I have no idea why  is    Went to LastPass  the service I use to keep all my passwords  Select my password by putting the cursor on top of the password and double clicking Once selected I press cmd C to copy Went to Android study and cmd V to paste   Notice I did try to copy many times by selecting the password by clicking at the end of the password and selecting the password by moving the mouse   It is strange but it only worked by double clicking on top of the password to copy it   Also I did use the Open Module Settings   Signing    method explained by  NightFury on this post

How i solved this  This error occurs because you have set your build variants to release mode  set it to build mode and run project again   If you want to run in release mode  just generate a signed apk the way we do it normally when releasing the app

Always sign your build using your build gradle DSL script like this       android       signingConfigs           debug               storeFile file  debug keystore                      myConfig               storeFile file  other keystore               storePassword  android              keyAlias  androidotherkey              keyPassword  android                       buildTypes           bar               debuggable true             jniDebugBuild true             signingConfig signingConfigs debug                   foo               debuggable false             jniDebugBuild false             signingConfig signingConfigs myConfig                     If you want to understand a little more of the Gradle build system associated to Android Studio just pay a visit to   Gradle Plugin User Guide

My problem was solved by changing the build variant as suggested by St  phane   if anyone was struggling to find the  Build variants  as I did here is a screenshot where you can find it

User · Answer

Make sure the build variant is set to debug  and not release  in Android Studio  check the build variants panel    If set to debug  it should automatically sign the app with the auto-generated debug keystore  without editing the build scripts   However you will need to create and configure a specific keystore for release   Official documentation  covering debug and release modes  https   developer android com tools publishing app-signing html
