same fcking message I've got. Tried everything.... with no luck. And I don't understand why nobody give a fck about it. At least somebody should tell us what is going on or how they set it up

In my case the background mode is already installed but sometimes when i launch the app the error occurs.

I installed this plugin and its Ionic Native wrapper today and got this exact same issue - or so I thought.

I wrapped every call to the plugin with this.platform.ready().then(() => ...) but still got the following error:

Native: tried calling BackgroundMode.unlock, but the BackgroundMode plugin is not installed.
Install the BackgroundMode plugin: 'ionic plugin add cordova-plugin-background-mode'

Then I realised I was actually successfully calling backgroundMode.enable() without error... it was only unlock(), wakeUp() and a few other methods from the documentation that were throwing that warning. I did some digging through the source code and it turned out those methods simply weren't even implemented in the version of the plugin I was using. This issue was actually already reported over a year ago - the latest semver-tagged version of the package resolved by npm (which cordova plugin add uses under the hood) is out of date.

To fix it, I changed the plugin spec from this:

<plugin name="cordova-plugin-background-mode" spec="^0.7.2" />

to this:

<plugin name="cordova-plugin-background-mode" spec="https://github.com/katzer/cordova-plugin-background-mode.git" />

Hope this helps someone!

I managed to fix the problem on my end. Turns out the installation of the plugin was silently failing. Running it on "verbose" mode revealed it: ionic cordova plugin add cordova-plugin-background-mode --verbose

After some digging, I tried the suggestion from Arun Girivasan, in a comment on this answer:

i fix the problem. downgraded cordova cli version. and reinstalled plugin

I was using cordova-cli version 9.0.0, downgraded to 8.1.2, and the plugin was installed successfully. Hope this helps someone.
