I have just finished and signed the apk through android studio, then I have did an apk protect through apkprotect.com when I am trying to upload the apk to play store I got this error " You uploaded an APK that is not zip aligned. You will need to run a zip align tool on your APK and upload it again. " if I upload the original apk I got no errors,
I have tried to add zipalign true in the build.gradle but nothing happened I have tried also disable and enable proguard .
You can run zipalign manually in command line
zipalign [-f] [-v] infile.apk outfile.apk Note that zipalign is located inside ${sdk.dir}\tools
For more details visit zipalign
[Update]
Also, If you need to sign it you can do that using
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore YOURKEYSTORE unsigned.apk alias_name (jarsigner is located inside java JDK_HOME/bin)
I got the same "You uploaded an APK that is not zip aligned... blah, blah" error when by mistake I tried to upload a DEBUG version of my .apk file to Google Play. It's a bit misleading error because the real problem is that you cannot distribute a debug version which additionally is not signed with your Google Android Developer key. (You can only upload an .apk compiled as release version, and it must be signed, which happens in the same step, at least if you're using Eclipse).
Make sure you distribute an .apk file which is your Signed Release version, as described here:
http://developer.android.com/tools/publishing/app-signing.html#releasecompile
This question and its answers are old; so we expect things to change. As of today, the zipalign tool is in the ANDROID_HOME directory under build-tools/[version]/ so my path is currently:
/android-sdk/build-tools/22.0.0/zipalign Using the zipalign tool is not necessarily the answer here though, what you actually need to do is sign your apk.
I was using Cordova, uploaded a signed APK but still got this error.
The ziptool is what helped me, it's located at ~AndroidSDK\build-tools\24.0.0\zipalign.exe
So for example :
"~\AndroidSDK\build-tools\24.0.0\zipalign.exe" -f -v 4 android-release-signed.apk android-release-signed-zipaligned.apk I was using Cordova and the command line getting this error. I opened the project in Android Studio and used Android Studio to build the signed apk and the error went away.
