Hi,
I have followed all the steps of your app development course and created final .apk file for android which is wplms signed.apk but when I try to install that app in the real android device it not even installing take a look on below link
https://drive.google.com/open?id=1QD-5TGuXiihzvcZQRzOHXywjjRPVtd3B
in here creativelearnings is just a keytool name which is used to sign your released apk
// key tool generate
keytool -genkey -v -keystore creativelearnings.keystore -alias creativelearnings -keyalg RSA -keysize 2048 -validity 10000
//released apk build
ionic cordova build --release android
//after release command copy your release apk to main folder where you run ionic serve then
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore creativelearnings.keystore android-release-unsigned.apk creativelearnings
//zip align
C:\Users\99fus\AppData\Local\Android\sdk\build-tools\27.0.3\zipalign.exe -v 4 android-release-unsigned.apk creativelearnings.apk
We already followed this step and I have sent you the application it's not working when I try to install in android it's not even installing
Well normally this error appears when one of the above steps were failed .
I guess the zipalign step is failing somewhere .
Did you zipalign your app .
Is debug apk file is installing fine ?
