Unable to open 'android-release-unsigned.apk' as zip archive (zipalign error)

Question

I am using Ionic to build a hybrid app. I have recently tried to build the Ionic app into an Android app but I get the following error when running ionic run android with the device connected:

It appears that I can build fine, running ionic build android --release manages to work without a problem, it's when I have to use the ZipAlign tool.

Running the tool manually like this: ~/Library/Developer/android-sdk-macosx/build-tools/23.0.2/zipalign -v 4 android-release-unsigned.apk egenius-app.apk tells me: Unable to open 'android-release-unsigned.apk' as zip archive.

I have tried downgrading my SDK to different versions, uninstalling and re-installing plugins and I'm not stuck, looking online doesn't provide a lot of help.

Does anyone know what I am missing?

Thanks, Alex.

UPDATE The moment I removed the dependancy Angular Material Design Icons the app built and signed successfully.

Answer 1

I had the error when the unsigned apk is not on the same directory with the zipalign file.

I fixed that one by putting the file path of the unsigned apk

./zipalign -v 4 /Users/mj/Projects/Ionic/myApp/platforms/android/app/build/outputs/apk/release/app-release-unsigned.apk my-signed-release.apk

Answer 2

try

ionic cordova plugin rm cordova-plugin-console 

then rerun the build, keytool, and jarsigner

Answer 3

I had the same problem and I tried using the following command

zipalign -v 4 /User/ionictutes/myioncApp/app-release-unsigned.apk appname.apk

Answer 4

You have to sign with jarsigner first. Then you will be able to zipalign it.

Quick explanation:

keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000

You’ll first be prompted to create a password for the keystore. Then, answer the rest of the nice tools’s questions and when it’s all done, you should have a file called my-release-key.keystore created in the current directory.

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore HelloWorld-release-unsigned.apk alias_name

After this process you should be able to:

zipalign -v 4 HelloWorld-release-unsigned.apk HelloWorld.apk

Hi Xelom, thank you for the response! I generated everything fine like you said to do, I got the keytool to generate the key and the signing worked fine, but when I tried zipping it I got: Users/alexandermcintosh/Library/Developer/android-sdk-macosx/build-tools/23.0.2/zipalign -v 4 android-release-unsigned.apk green-running.apk Unable to open 'android-release-unsigned.apk' as zip archive So it still gives the same error. – Subservience

I haven't tested this solution 100% as yet but I am able to go through the process as normal after I remove the bower dependancy for Angular Material. It even runs on the device, just is a shame since most of the project depends on Angular Material. – Subservience

Looks like it was specifically this dependancy: Angular Material Icons – Subservience

Are you adding icons to your project or trying to download them? It is not a good practice to download them in a mobile application. – Incombustible

I was adding icons to the project, I was making the app have as little need for an active internet connection as possible. Literally removing from my bower.json the dependancy material-design-icons stopped all the errors thus far. – Subservience

Answer 5

Today I got the same issue in my Mac OS and I resolved it by taking below steps.

1. First I copied android-release-unsigned.apk from path:

   /Applications/XAMPP/xamppfiles/htdocs/Old Projects/kcformulas-2020/mesh-formula/platforms/android/build/outputs/apk/release/android-release-unsigned.apk
   

   to my current Ionic Project folder i.e.

   /Applications/XAMPP/xamppfiles/htdocs/Old Projects/kcformulas-2020/mesh-formula 
   

2. After that I run below command :-

   jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore android-release-unsigned.apk mesh_formula
   

3. After that I run below command by giving complete path to zipalign like below :-

   /Users/amitgupta/Library/Android/sdk/build-tools/29.0.2/zipalign -v 4 android-release-unsigned.apk KCMeshFormula.apk
   

   My APK successfully generated after taking above steps.

Hope it will help someone in future.

Answer 6

I had the same problem and it worked using the complete path.

For example:

zipalign -v 4 /Users/rafaelsantiago/app/platforms/android/app/build/outputs/apk/release/app-release-unsigned.apk app.apk
