I was also facing the same issue  First I generated build using V2 and installed that in mobile devices running on OS 5 1 and I got the same issue  But build was working fine on Tablet running on OS 7 0  So I generated build with V1 Jar signature and it was working fine on both the devices   Conclusion  If you are supporting the device below android OS 7 0  Use V1 jar signature to generate the build

most answers are true   and some another reasons that happens are        your min sdk smaller than device sdk      you have the older application in your device with the same package name

Did you edit the AndroidManifest xml directly in the  apk file   If so  that won t work   Every Android  apk needs to be signed if it is going to be installed on a phone  even if you re not installing through the Market   The development tools work round this by signing with a development certificate but the  apk is still signed   One use of this is so a device can tell if an  apk is a valid upgrade for an installed application  since if it is the Certificates will be the same   So if you make any changes to your app at all you ll need to rebuild the  apk so it gets signed properly

This is an ugly but fast solution  use JDK 6 instead of 7   After read Chloe s answer  I uninstalled my JDK 7  don t need it currently anyways  and installed JDK 6  That fixed it  A better solution would make ant uses JDK 6  without uninstalling 7   Maybe possible changing   setting this property   java library path  in local properties file  It s in the project directory  root    Android doesn t work with JDK 7 anyways  only 6 or 5   so make that the ant script also uses JDK 6 or 5 is probably a good solution

Firstly just try to do that    go to Gradle script   bulid gradle module app    then you have to change  minSdkVersion  value  As an example  if you used 26 you can try to decrease the value  like  minSdkVersion 20   then try  sync now

In my case  I could build and run release builds  but got the INSTALL PARSE FAILED NO CERTIFICATES error when trying to do a debug build   The solution was to delete my debug keystore file and let ADT recreate it   It had apparently expired   A better long-term solution is to explicitly create a debug keystore that does not expire after only a year  instead of letting ADT create it  Here is the command to do that   keytool -genkey -v -keystore debug keystore -alias androiddebugkey -storepass android -keypass android -keyalg RSA -validity 14000   When prompted  enter these values    First and last name  Android Debug Organizational unit  Android Name of organization  Unknown City or Locality  Unknown State or Province  Unknown Country code  US

This error could be thrown if you add your signing config create signing key and add to the  quot Project Structure quot   gt   quot Modules quot   gt   quot Signing Configs quot   but forget to point out in  quot Project Structure quot   gt   quot Build Variants quot   gt   quot Build Types quot   gt   quot Signing Config quot   The signing config field shouldn t be empty   Like in the picture below  Otherwise  you will see  quot INSTALL PARSE FAILED NO CERTIFICATES   APK signature verification failed  quot    error if you try to install a release variant   or another variant with the same misconfiguration

This could happen if you try to include a  jar library that contains an  AndroidManifest xml file    If it s pure Java make sure you don t include it in the  jar export If it s not pure Java  meaning it s an Android project  then you have to include it as a Library Project

Another way to get this error is to build using ant on macOS and have a Finder icon file  Icon r  in the source tree of the app   It appears jarsigner can t cope with the carriage return in the filename and  although it will claim the signing is valid if you -verify the APK  it always results in an APK that wont install on a device   Ironically  the Google Drive Finder plugin is a great source of Finder icon files   The solution is to exclude the offending files  which are useless in the APK anyway  with a specifier like this in the fileset        lt exclude name     Icon amp  13     gt

I found that this error can now also occur when using the wrong signing config   As described here  Android 7 0 introduces a new signature scheme  V2  The V2 scheme signs the entire APK rather than just the JAR  as is done in the V1 scheme   If you sign with only V2  and attempt to install on a pre-7 0 target  you ll get this error since the JARs themselves are not signed and the pre-7 0 PackageManager cannot detect the presence of the V2 APK signature   To be compatible with all target systems  make sure the APK is signed with both schemes by checking both signature version boxes in Android Studio s Generate Signed APK dialog as shown here     If only 7 0 targets are anticipated  then there is no need to include the V1 signature

Recently I had this error while upgrading to Android Studio 4 0  The cause was that the project had V2 Signing Disabled in the signing configuration in build gradle   The solution was to remove v2SigningEnabled false or explicitly set it to true  which is the default value   android           signingConfigs           dev               v2SigningEnabled true
