In ionic 4, how to do a release aka prod build?
The angular part can be build in prod mode by ionic build --prod
Now how to copy this build to android? If I do ionic capacitor run android it will do normal build first and then copy assets to android. But I want to build in prod mode and take assets to android.
(I know how to generate apk in Android studio)
After doing
ionic build --prod
Assuming you have already installed Capacitor, otherwise you can follow this and thereafter,
You can do the following
npx cap copy android
Which copies the built code to android folder.
Then you can do
npx cap open android
Which opens android studio if you havent opened it already, then you should go to Build -> Generate Signed Bundle / APK option and the rest is quite straightforward.
More info can be found here
You can use the simple way.
ionic capacitor build android --prod
after the command, the android studio will open automatic
Development:
android stdio: Build-> Build Bundle(s)/APK(s)->Build APk(s)
Production: android stdio: Build-> Generate Signed Bundle(s)/APK(s)-> Android App Bundle or APk-> release
Error when building for the device
I am getting an error when I try to build for the device(ionic cordova run android --device). For some reason it is not creating platforms/android/app/build/outputs/apk/debug/app-debug/apk. I have tried removing and adding android different versions. Also, I have tried ionic cordova run android --no-native-run and it loads but with a blank screen.
I found 2 solutions, so if you have a problem with running the device feature:
Update CLI!
Remove Android
ionic cordova platform rm android
Add android#6 and run ionic cordova run android --no-native-run
OR
3.add the latest android#latest and run ionic cordova run android.
Those two worked for me, depending on the version of your projects!
Please Explain me difference between:
ionic cordova build android -> .apk Slowin loading
ionic cordova build android --prod -> .apk Fast in loading
ionic cordova build android --prod --release -> .apk Slow in loading
Thanks
Without flags it generates the apk debug version. And with release it generates the apk ready for the store but unsigned when you sign it you can upload it.
The --prod flag:
This will minify your app’s code as Ionic’s source and also remove any debugging capabilities from the APK.
I'm trying to install my ionic app on my android phone. I tried
install my ionic app on my android phone
The app ran on my phone, but when I ran the same command to run a different app, the app was replaced on my mobile. How can I keep both? I don't intend to modify any of these apps, they are ready. I tried these commands as well:
ionic cordova build android --prod --release
and
ionic cordova run android --prod --release
I got this error message:
[ERROR] An error occurred while running cordova run android --release
(exit code 1)
By default, it will overwrite the previous version. You can keep the both app using below way:
Check the config.xml file, and change the id of the app.
<widget id="new.app.id" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">
Now, it will be considered as a different app and will not replace the previous one.
