How to install and use ZIPALIGN on ubuntu 16.04 64bit?

[Barney Gumble Channel]

i tryng to upload an apk on google developer but my apk is not zipaligned Cheers and Thanks

[ZenCODE]

In your home folder, your zipalign tool is stored in

    ~/.buildozer/android/platform/android-sdk-<sdk_no>/build-tools/<rev_no>/

You'll need to look to see exactly which versions are installed.

Instructions for using zipalign are here: https://developer.android.com/studio/command-line/zipalign.html

Hello Zen
sorry I'm a beginner,is this path in the kivy virtual machine? ~/.buildozer/android/platform/

android-sdk-<sdk_no>/build-tools/<rev_no>/  Do I have to open android studio to run zipalign?   thank you very much

[ZenCODE]

 Yes, that path in the the kivy VM. You'll need to change into that folder and then run

    ./zipalign -v 4 .....

i have try for 1 hour , i have not  find this path,can you  help me with a noob tutorial ? can u write me precisily because the kivy vm are all the same,thank you very much Zen

[ZenCODE]

The paths are not all the same as they depend on the sdk version you have chosen and the revision number most recently installed. Are you sure you have you sdk installed. Have you tried searching in you ./buildozer folder for zipalign?

[ZenCODE]

From inside the .buildozer folder...

    find ./ -name "zipalign"

[Barney Gumble Channel]

hello zen I can find this directory ~/.buildozer/android/platform$ android-sdk-<sdk_no>/build-tools/<rev_no>/
bash: sdk_no: No such file or directory

kivy@kivyvm:~/.buildozer$ find ./ -name "zipalign"
./android/platform/android-sdk-21/tools/zipalign
./android/platform/android-sdk-21/build-tools/19.1.0/zipalign
./android/platform/android-sdk-20/tools/zipalign
./android/platform/android-sdk-20/build-tools/19.1.0/zipalign



 ~/.buildozer/android/platform$ ls
android                               android-sdk_r20-linux.tgz
android-ndk-r9c                       android-sdk_r21-linux.tgz

HI Zen when u have time please help me understund thank you very much

[ZenCODE]

Yes, the values in angle brackets are placeholders. They change depending upon your sdk. So, your search shows you where the zipalign command is. So, do a:

    cd ~/.buildozer/android/platform/android-sdk-21/build-tools/19.1.0/

You should then be able the run:

    ./zipalign -v 4 ...

where you replace the ... with the paths to your apk and output apk as documented for the zipalign command (link given in previous posts). If that is still unclear, perhaps do a tutorial on linux and how to run commands? Good luck

Zen i tryng but i have not understund

the name of my apk is   MyApplication-0.1-release-unsigned.apk

the path is   /home/kivy/Desktop/provaAPP/bin

[ZenCODE]

Note the dot forward slash before zipalign,

./zipalign -v 4 ~/home/kivy/Desktop/provaAPP/bin/MyApplication-0.1-release-unsigned.apk

  <align>: alignment in bytes, e.g. '4' provides 32-bit alignment
  -c: check alignment only (does not modify file)

i dont know why no work i have read some information output input but i have no understund thanks always Zen

[ZenCODE]

You need to specify the output file as well.

    
./zipalign -v 4 ~/home/kivy/Desktop/provaAPP/bin/MyApplication-0.1-release-unsigned.apk  ~/home/kivy/Desktop/provaAPP/bin/MyApplication-0.1-aligned.apk

[Barney Gumble Channel]

No work

kivy@kivyvm:~/.buildozer/android/platform/android-sdk-21/build-tools/19.1.0$ ./zipalign -v 4 ~/home/kivy/Desktop/provaAPP/bin/MyApplication-0.1-release-unsigned.apk

[ZenCODE]

You need both the input file path and the output one. Like I posted above. You have only entered one path in your command.

READ THIS AFTER INSERT BOTH COMMANDS Unable to open '/home/kivy/home/kivy/Desktop/provaAPP/bin/MyApplication-0.1-release-unsigned.apk' as zip archive

[ZenCODE]

You need to sign it in order to upload. That is a requirement of the google Play store.

[Barney Gumble Channel]

Thanks Zen but can u help me here  with keystore,Thanks you so much for your support!!!

The requirements for make application are  keystore,signapk and zipalign ???

[ZenCODE]

That is all standard Java android stuff and not Kivy specific. A google reveals lot's of tutorials and examples. There is lots of help out there on this. Just try it and make a new post if you get stuck.  Good luck :-)

[Barney Gumble Channel]

Hello ZenThanks again for your help :) i try find in google. If i get stuck i will open a new post here Cheers :)

Hello zen

I try install zipalign on kali linux 2018.3 rolling

apt-get install zipalign
Reading package lists... Done
Building dependency tree      
Reading state information... Done
Package zipalign is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'zipalign' has no installation candidate

Please help me

[ZenCODE]

zipalign installs with the android sdk. If you're using buildozer, it would be something like

/home/<username>/.buildozer/android/platform/android-sdk-23/build-tools/23.0.1/zipalign
