React-native-map Android

In this tutorial we will take a look at displaying Google Maps in a React Native application and for that we need to make a api key with google developer console.

npm install react-native-maps --save
react-native link

//In current version don't need to follow old version steps below steps only you need to add steps for androidX
If your RN project is configured to use AndroidX, but some of your deps are not (like react-native-gesture-handler) follow these steps:
1. Install Jetifier npm install --save-dev jetifier or yarn add -D jetifier
2. Edit your package.json and add a postinstall script: "postinstall": "npx jetify", like so:"scripts": {
3. "postinstall": "npx jetify"
4. ...
5. }
6.
7. Run npm install or yarn
8. At the end of install you should see something like:$ npx jetify
9. Jetifier found N file(s) to forward-jetify. Using X workers....
10.This means it's working. The project should compile fine now.
This way jetfier will "upgrade" all deps to use AndroidX. This step has to be repeated after each installation, hence the "postinstall" step.

And after this you get this issue:
Issue: “Failed to capture fingerprint of input files for task ':app:bundleReleaseJsAndAssets' property '$1' during up-to-date check.
Could not list contents of '/Users/apple/Desktop/Fitmon/node_modules/node-pre-gyp/node_modules/.bin/needle'. Couldn't follow symbolic link.”
Resolved: during release mode then remove node_module and run npm install to install again then create build.

And
Issue: Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to application element at AndroidManifest.xml:7:5-117 to override.
Resolved:
Add in gradle.properties:
android.useAndroidX=true
android.enableJetifier=true
//**************** end ****************/



//Use for old version
