Answer 1

You can install and see the debug version of the App using the command :

ionic cordova build android ( ie. without the Release flag --release )

If you want to install and see the Release version of your App, then you need to sign your App using a Key.

Step 1 : Generate your Private Key ( if you have one, then discard this step ) :

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

Step 2 : Sign your APK

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

Step 3 : Optimize your Apk using Zipalign

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

Refer this Link : https://ionicframework.com/docs/intro/deploying/ (Android Section)

Answer 2

The generate APK is unsigned (app-release-unsigned.apk). You can only install an unsigned APK on a emulator not a physical device.

BUILD SUCCESSFUL

This means that the APK has built, it will be located here:

Copy\platforms\android\build\outputs\apk\android-release-unsigned.apk

then to install run this through terminal (if mac):

adb install PASTEHEREYOURPATH.apk

The generate APK is unsigned (app-release-unsigned.apk). You can only install an unsigned APK on a emulator not a physical device.
