cannot find zip-align when publishing app

Question

cannot find zip align The zipalign tool was not found in the SDK   Please update to the latest SDK and re-export your application or run zipalign manually   Aligning applications allows Android to use application resources more efficiently    This is the message I received when I tried to publish my app  I m using the latest revision of Android SDK Tools  23 which was released today  and SDK Platform-tools  20 which was also released today   I got an APK out of it  but if I tried to upload it to Google Play I got an error complaining that it is not zip aligned   Running zipalign manually fixes the apk  but does anyone know what causes this and how to fix it

When I was completely desperate  I did the following  that allowed me to find official zipalign exe  The short answer is to use the link from official  but not public  -  part of of the site   https   dl google com android repository build-tools r28-rc1-windows zip   If you use this recepy after 2018  you probably need the full explanation    Open Android Studio and go   Android Studio- gt Tools- gt Android- gt SDK Manager- gt Android SDK- gt SDK update site  Write in text editor link and open it in the browser  In my case the first link worked for me   https   dl google com android repository repository2-1 xml  Look for the latest package build-tools  In my case  it was build-tools r28-rc1-windows zip  but you can find the latest in your time  Ctrl F build-tools   Substitute in the URL the last part with the found package name like I did   https   dl google com android repository build-tools r28-rc1-windows zip  Download the package  unzip it and fortunately find official file   zipalign exe    If it helps you  your feedback is wellcome

If you are using gradle just update ypur gradle plugin   Change line in build gradle from   classpath  com android tools build gradle 0 9      to   classpath  com android tools build gradle 0 11      It works for me    Note that variable buildToolsVersion  for me  20 0 0   must match your version of build-tools   Good luck

zipalign was moved to build-tools 19 1 0 and build-tools 20 0 0  I assume you should use one of them in depend of your target SDK

I use Eclipse and this broke during an update  Here s what worked for me as the answers above did not  I checked where ant s build xml expected to find zipalign exe   In  C  Development Android android-sdk tools ant build xml zipalign is defined as    lt property name  zipalign  location    android build tools dir  zipalign  exe     gt    which indicates its expected in    C  Development Android android-sdk build-tools 18 0 1   This directory corresponds to the highest version of the  Android SDK Build-tools  displayed as installed in the  Android SDK Manager   So  that s where I copied zipalign exe  which I obtained from an Android Studio installation   and signed apps are now automatically zipaligned again

Zipalign gradle task is deprecated since Android Plugin for Gradle  Revision 2 2 0  September 2016    If you want to keep using it  add android useOldPackaging true to your gradle properties file   Click here for detailed explanation      Improves build performance by adopting a new default packaging pipeline which handles zipping  signing  and zipaligning in one task  You can revert to using the older packaging tools by adding android useOldPackaging true to your gradle properties file  While using the new packaging tool  the zipalignDebug task is not available  However  you can create one yourself by calling the createZipAlignTask String taskName  File inputFile  File outputFile  method    APK signing now uses APK Signature Scheme v2 in addition to traditional JAR signing  All Android platforms accept the resulting APKs  Any modification to these APKs after signing invalidates their v2 signatures and prevents installation on a device     Blockquote

I had the same problem   And to fix it  I copy the Zipalign file from sdk build-tools android-4 4W folder to sdk tools   Edited  Since Google updated SDK for Android  new build-tools does fix this problem  So I encouraged everyone to update to Android SDK Build-tools 20 as suggested by Pang in the post below

User · Answer

Normally the zipalign exe is close of the  Android manager  also   Android    Android SDK  etc   so you can search for  Android Manager  in windows search and give a righ-click above the command and open file location  You probably are in  something  Android android-sdk tools  Then is just necessary return a folder and go to Android android-sdk build-tools 23 0 3  The zipalign is there  you maybe be not able to use it with double-click  so you have to copy all the path of the zipalign file to use in CMD  the final code that you have to input will be something like      C  Users heitor AppData Local Android android-sdk build-tools 23 0 1 zipalign exe -v 4 android apk android2 apk

With the SDK update to 20  version 20 of the build and platform tools and 23 of the sdk tolls  Google has moved a lot of things   Gradle  if you are using Android Studio  however has not yet been updated to reflect those changes  as stated in other Answers copying the zipalign binary to  sdk tools  should do the trick for now   UPDATE  since Android Studio 0 8 1 got released the issue seems fixed now    you only need to update your build gradle and it should work fine again  compileSdkVersion 20  buildToolsVersion  20 0 0   targetSdkVersion 20  and if you use any compat or support library  compile  com android support appcompat-v7 20     compile  com android support support-v4 20
