Android deployment

1. Make sure you are in the parent directory cd six-minute-walk-distance

2. Build android for Prod/Release ionic build android --prod --release

3. Take note of the apk path Built the following apk(s): /Users/computerName/Projects/six-minute-walk-distance/platforms/android/build/outputs/apk/android-release-unsigned.apk

4. Generate a Key keytool -genkey -v -keystore sixmwd.keystore -keyalg RSA -keysize 2048 -validity 10000 -alias sixmwd

5. Copy unsigned app from six-minute-walk-distance/platforms/android/build/outputs/apk/android-release-unsigned.apk to current folder (six-minute-walk-distance)

6. Rename apk file to sixmwd-unsigned.apk (optional)

7. Sign the APK jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore sixmwd.keystore sixmwd.apk sixmwd

8. Optimise the APK with zipalign

Copy zipalign file ~/Library/Android/sdk/build-tools/VERSION/zipalign to current folder (six-minute-walk-test)

run the command with dot slash ./ so that the command will be ./zipalign -v 4 sixmwd-unsigned.apk sixmwd.apk

It should return Verification successful

9. Verify (pending success)

Unfortunately I haven’t figured out how to verify with apksigner, I tried copying the apksigner file from the same folder as zipalign file but I get can’t find apksigner.jar error

Celebrate, you now have a signed apk file that you can upload to Google Play store
