Cannot read property 'uploadservice' of undefined

[mikeres0]

I am attempting to use this plugin within my app, however I receive an error upon navigating to the page where the plugin is required. The error I receive is Cannot read property 'uploadservice' of undefined which relates to line 8 of background-http.js.

[PanayotCankov]

Can you add the plugin using tns plugin add nativescript-background-http then delete the platforms folder and re-run for android? The fails seem to happen very early at obtaining com.alexbbb.uploadservice which seems the underlying native android implementation didn't make it to your app. Possible problems may be the plugin was added using npm install rather than tns plugin add, or the Android gradle may have mis-cached the metadata prior to adding this library.

Please write back if cleaning platforms and tns plugin add do not fix the problem so we can investigate it further.

[mikeres0]

Which platforms folder? As in node_modules/nativescript-background-http/platforms or the platforms directory at the root of my project?

[PanayotCankov]

The one at the root of your project.

[mikeres0]

No luck unfortunately, I'm still receiving the same error message

[PanayotCankov]

I can not reproduce the problem. Can you share the versions of the NativeScript framework you are using tns --version and provide the versions in the pakcage.json? Also do you test on device or emulator?

[mikeres0]

My CLI version is 1.6.2 and the versions in my package.json are as follows:

{
    "nativescript": {
        "id": "org.nativescript.nextraworkplan2",
        "tns-ios": {
            "version": "1.6.0"
        },
        "tns-android": {
            "version": "1.6.2"
        }
    },
    "dependencies": {
        "nativescript-background-http": "0.0.3",
        "nativescript-insomnia": "^1.1.0",
        "nativescript-local-notifications": "^1.0.0",
        "nativescript-sqlite": "^1.0.7",
        "node-uuid": "^1.4.7",
        "tns-core-modules": "^1.6.0"
    }
}

I am testing on two physical devices; Samsung Galaxy S5 and iPad Air.

[PanayotCankov]

iPad Air shouldn't generate a Cannot read property 'uploadservice' of undefined message. What is the error on iOS? Also what is the android version installed on the Galaxy S5? I think we have S5 and will give it a try but there may be differences in the API level.

[mikeres0]

I may be wrong about iOS. As I don't have access to that device today I won't be able to confirm.

The android version of the S5 is 5.0. Okay, thank you.

I have the exact same error in my nativeScript app, I'm using a Nexus 5X on the emulator. I tried deleting the platforms folder and adding the plugin.
Any ideas on how can I fix that?

Thank you

[anchetaWern]

same problem here. I tried installing with npm and tns plugin add but I still get the same error.

[chief10]

Same error here. Running in Genymotion; Android 7.0

[viniciodeltoro]

I ended up using the regular HTTP module that angular 2 provides and uploading the image as a Based64 string in a JSON object. I convert back that string on the server side. That works very good but obviously it's not working in the backgroud

[joona]

I running into the same problem. Testing on Genymotion, Android 6.0 and on Nexus 6P with Android 7.0.

"nativescript": {
  "tns-android": {
    "version": "2.2.0"
  }
}

Same problem here, Using {N} 2.3.0, everything 2.3.0, real device, a galaxy S5, no ideas then?

[PanayotCankov]

Try 2.4.0, aar has been replaced with include.gradle

[felixkrautschuk]

When updating to the latest version of this plugin (2.5.0), I get the same error message on Android.
Cannot read property 'uploadservice' of undefined

I am using tns-core-modules 2.5.0.
