[ANDROID] Not working when following the instructions + SOLUTION

[Daavidaviid]

Your Environment

• Plugin version:
• Platform: Android
• OS version: 10.0
• Device manufacturer and model: Doesn't matter

• Running in Simulator: Yes
• React Native version: 0.61.5
• Plugin configuration options: 0.6.3
• Link to your project: Nope

Context

Not working on android after following the instructions, ie :

• Add the library with yarn add @mauron85/react-native-background-geolocation
• Launch the script using node ./node_modules/@mauron85/react-native-background-geolocation/scripts/postlink.js

Expected Behavior

The app is now able to use background geolocation and build correctly and not crash

Actual Behavior

Build fails.

Possible Fix

I think jetifier was not picking up the common module. So I migrated everything to androidx using Android Studio. And also in the file VERSION.gradle there was an issue with getApplicationId that I fixed too.
You can use the package patch-package.
And then apply this patch patches/@mauron85+react-native-background-geolocation+0.6.3.patch :

Steps to Reproduce

1. New react native project
2. Install the library using instructions
3. Cry
4. Apply my patch and rejoice

Context

Add background geolocation to my app.

I too ran into the VERSIONS.gradle issue in the common module. I opened a PR there that you can reference. Hoping it can get resolved soon (mauron85/background-geolocation-android#41)

[RWOverdijk]

@mysport12 Do you think these two are related? I think androidX support is lacking so the patch seems more reasonable to me. Unless I'm missing something, in which case I'm curious how I can test what you're proposing in your PR?

[RWOverdijk]

@Daavidaviid Could you make this into a PR? Patches work but PRs are better 😄

[RWOverdijk]

@mauron85 I've run the patch and verified that it works.

[Daavidaviid]

I made a patch because the common module is in another repo and I don't know if @mauron85 is maintaining this library actively to validate PRs.

[mikadze]

Hi @Daavidaviid
I tried to apply the patch and got the following error:

**ERROR** Failed to apply patch for package @mauron85/react-native-background-geolocation at path
  
    node_modules/@mauron85/react-native-background-geolocation

  This error was caused because patch-package cannot apply the following patch file:

    patches/@mauron85+react-native-background-geolocation+0.6.3.patch

[Daavidaviid]

@mikadze I updated the patches in my first post (I messed up by removing the local.properties section by hand), try again

[mysport12]

For me the only issue was in VERSIONS.gradle. I had no other build issues and didn’t need to patch anything else

[mikadze]

@Daavidaviid first post was last edited 1 hour ago. I tried that version. Did you make edit since then?

[Daavidaviid]

I did but here it is :

[mikadze]

Still not working for me, but thanks anyways I will try manually.

[Daavidaviid]

I made 2 PR, one concerning the main repo and the other one the submodule.
Main : #471 Sub : mauron85/background-geolocation-android#42

[RWOverdijk]

@mauron85 Need help with this lib (/ these libs)? They're important to my apps and I really prefer not forking anything.

[igor-nm]

Any updates about it ? I'm getting a error too, just with VERSIONS.gradle ...
