Build Issue " unknown property cdvCompileSdkVersion"

[Jason6Ping]

Hi,
I met build issue after I install the plugin, the error is:

"Could not get unknown property 'cdvCompileSdkVersion' for object of type com.android.build.gradle.LibraryExtension."

I just follow the steps mentioned in Adding an Android APK Expansion File to a Cordova Project and also downgraded the Cordova to 6.5.

Also, I have tried change the "build-extra.gradle" file in this plugin by modifying dependencies to "implementation project(':com.flyingsoftgames.xapkreader:library')" but I still get same error.

Does anyone have idea on this?
Thanks.

Hey,
Any news on this or were you able to solve it? I'm getting the same error.

Hi,

four months after the last request I ran into the same issue...
Is there any information about solving this error?
I already took a look at the other build issues but non of these seems to fix this problem...

In the fork timeline, a few people forked to 8.0. Check if that solves your issue.

Is there an easier way to find than checking all forks? Sorry, I am not the firm with github...

[agamemnus]

Yes, there's a timeline somewhere, although when I checked just now it was gone, or maybe I checked in the wrong place.

In any event, I did incidentally look at the forks earlier yesterday, so here's one to try:
https://github.com/devtobo/cordova-plugin-xapkreader

Let me know how it goes!

First of all: thanks a lot for your support and linking to the version.

I have tried different combinations of cordova-android and the plugin.
Due to some building errors ("Execution failed for task ':app:mergeDebugAssets'.

unable to create new native thread") that occured randomly I just recreated my complete app using the newest version of all tools. I suppose these errors were releated to adding and removing different android- platform versions.

my steps:

• create new project
• add all plugins (incl. the linked version of xapkreader)
• add platform android@latest (8.0.0)
• build
  Build is terminated with error:

* Where:
Build file '/Users/jahn/appONE/app-v2/hamminkelnNew/platforms/android/com.flyingsoftgames.xapkreader/apphamminkeln-downloader_library/build.gradle' line: 45

* What went wrong:
A problem occurred evaluating project ':com.flyingsoftgames.xapkreader:downloader_library'.
> Could not get unknown property 'cdvCompileSdkVersion' for object of type com.android.build.gradle.LibraryExtension.

😞
As far as I get from cordova documentation cdvCompileSdkVersion is a build wide variable that should be available? Has anyone further ideas?

This issue seems to stem from Cordova using an outdated plugin-build.gradle file, which is used to generate the final plugin build.gradle configs. If anyone is still having a problem with this, I was able to fix it using a before_plugin_install hook script. See here:
https://github.com/erobertson42/cordova-plugin-xapkreader/blob/cordova-9/scripts/before_install.js

I'm also doing a couple other things in this script unrelated to this issue, so if they don't apply to you, just remove lines 11-15.
