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
