Ionic-cli: Ionic 4+ android build error: package android.support.annotation does not exist; import android.support.annotation.RequiresApi;

[gireeshspr]

Description:

Ionic 4+ app fails to build after adding the firebasex package

Steps to Reproduce:
Step 1: Create a latest blank ionic project
Step 2: Added the firebasex package onto the Ionic 4+ project

       ionic cordova plugin add cordova-plugin-firebasex
       npm install @ionic-native/firebase-x

Step 3: Generate google-services.json from firebase project and add to the project folder
Step 4: Add android platform and build for android
Error received: Getting the following error when build for android
This project uses AndroidX dependencies, but the 'android.useAndroidX' property is not enabled. Set this property to
true in the gradle.properties file and retry.

Step 5: Modify platforms/android/gradle.properties as follows and rebuild
android.useAndroidX=true,
android.enableJetifier=true

    Same error as step 4 received and the flags get reset automatically to 'false' as follows
    org.gradle.daemon=true
    org.gradle.jvmargs=-Xmx2048m
    android.useAndroidX=false 
    android.enableJetifier=false
    cdvMinSdkVersion=22

Step 6: Add < preference name="AndroidXEnabled" value="true" /> in config.xml
ionic cordova prepare android
build for android

Any updates on the above issue?

I just found out that Cordova Platforms : android 9.0.0 is causing the issue.
I have downgraded the version to 8.1.0 and the build issue disappeared. But the ionic cordova run android --emulator is no longer working

Hope this will help to resolve the issue with latest version of android 9.0.0

[victoriaunizhona]

any news on that?

[gireeshspr]

Any updates? The latest cordova-android 9.0.0 causing this issue.

Hi Guys, I hope i am not very late to reply but i think, this issue can be avoided by adding ionic cordova plugin add cordova-plugin-androidx and ionic cordova plugin add cordova-plugin-androidx-adapter all you have to do is run this command and the error will be disappeared. The error comes because this project is not using androidX but these plugins solve error.

Works for me, thanks so much!

Although this does make your app build, it doesn't really solve the problem, as the plugin author @dpa99c notes:

https://github.com/dpa99c/cordova-plugin-androidx#deprecation-notice

This plugin is deprecated as it's no longer required since cordova-android@9 adds built-in support for AndroidX.
This plugin is only needed if your project uses legacy cordova-android@8.
If you update to cordova-android@9 and your project contains this plugin then you should remove it.

So I'm kinda hoping this issue "is" going to get looked at

Edit:

The way I got this to build with cordova-android 9:

#start without the androidx plugins installed
ionic cordova plugin remove cordova-plugin-androidx
ionic cordova plugin remove cordova-plugin-androidx-adapter

#also remove the platform
ionic cordova platform add android

#re-add everything
--ionic cordova plugin add cordova-plugin-androidx--- (not needed see further edit below)
ionic cordova plugin add cordova-plugin-androidx-adapter
ionic cordova platform add android

#make sure your config.xml will work, I had to add to the android platform section (YMMV):
<preference name="AndroidXEnabled" value="true"/> (see further edit below)
<preference name="android-minSdkVersion" value="22" /> 
<preference name="android-targetSdkVersion" value="29"/> 

#build
ionic cordova build android

---only downside, is my /platform/android/gradle.properties now seems to fill up with spurious additions of android.useAndroidX and android.enableJetifier--- <- nope, this doesn't happen if you "don't" use this cordova-plugin-androidx plugin

Further Edit:

I just realised that all the cordova-plugin-androidx plugin does is add in the androidx=true stuff in config.xml. if you then use the recommended

<preference name="AndroidXEnabled" value="true"/>

as suggested by the OP (and referenced here: https://cordova.apache.org/announcements/2020/06/29/cordova-android-9.0.0.html) then you don't actually need that plugin, but you "do" still need the cordova-plugin-androidx-adapter plugin
