Explains how to disable the auto-merged FirebaseInitProvider by adding a manifest override with tools:node="remove", and how to manually initialize Firebase using FirebaseApp.initializeApp(Context, FirebaseOptions) with values pulled from google-services.json. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I disable FirebaseInitProvider so I can manually initialize Firebase on Android? Override the FirebaseInitProvider entry in your app's AndroidManifest.xml using a node marker that sets tools:node to "remove", which prevents Android build tools from merging the provider into your app. You must also declare the tools namespace in the manifest root tag if it isn't already present. After removing it, call FirebaseApp.initializeApp() yourself. _daily.dev surfaces practical Firebase and Android build configuration guides like this one for developers customizing their init flow._ ### How do I manually initialize Firebase with FirebaseOptions instead of google-services.json? Call FirebaseApp.initializeApp(Context, FirebaseOptions), building a FirebaseOptions object via its Builder with setApplicationId, setApiKey, setDatabaseUrl, and setStorageBucket, using values pulled from your google-services.json file. This lets you initialize Firebase without the Google Services Gradle plugin, useful for custom build systems like Bazel or runtime project selection. _Developers switching Firebase projects at runtime can find these initialization patterns curated on daily.dev._ ## Similar posts on daily.dev - [24/28: Code Runs Before Your Application.onCreate: Here’s What](https://daily.dev/posts/24-28-code-runs-before-your-application-oncreate-here-s-what-5ze1roro5) · Medium · 0 upvotes · 0 comments - [Build intelligent Android apps: Cloud and hybrid inference](https://daily.dev/posts/build-intelligent-android-apps-cloud-and-hybrid-inference-eyctih4y9) · Android Developers Blog · 0 upvotes · 0 comments - [Using Flutter with Firebase: A Developer's Guide](https://daily.dev/posts/using-flutter-with-firebase-a-developer-s-guide-jbpavk3vl) · Flutter Community · 0 upvotes · 0 comments - [Kotlin / Wasm — Auth part 1: Google Sign in](https://daily.dev/posts/kotlin-wasm-auth-part-1-google-sign-in-dp1b4k1zm) · ProAndroidDev · 0 upvotes · 0 comments - [Medium](https://daily.dev/posts/medium-sntfm8mrk) · Medium · 1 upvotes · 0 comments --- Tags: [#android](https://daily.dev/tags/android), [#firebase](https://daily.dev/tags/firebase), [#gradle](https://daily.dev/tags/gradle), [#build-systems](https://daily.dev/tags/build-systems) [View this post on daily.dev](https://daily.dev/posts/take-control-of-your-firebase-init-on-android-ojner0y4k) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Take Control of Your Firebase Init on Android","url":"https://daily.dev/posts/take-control-of-your-firebase-init-on-android-ojner0y4k","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/take-control-of-your-firebase-init-on-android-ojner0y4k"},"datePublished":"2026-08-23T12:20:50.675Z","dateModified":"2026-08-23T12:34:05.704Z","description":"Guidance for Android developers who cannot rely on Firebase's automatic initialization via the Google Services Gradle Plugin - for example when using a custom...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7ed721de96163685d26ab7e314be3ebc?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7ed721de96163685d26ab7e314be3ebc?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Firebase","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Firebase","logo":"https://media.daily.dev/image/upload/s--i395oqZH--/f_auto,q_auto/v1787487448/logos/firebase-blog?_a=BAMAMicg0","url":"https://daily.dev/sources/firebase-blog"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/take-control-of-your-firebase-init-on-android-ojner0y4k","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"android,firebase,gradle,build-systems","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Firebase","item":"https://daily.dev/sources/firebase-blog"},{"@type":"ListItem","position":3,"name":"Take Control of Your Firebase Init on Android"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/take-control-of-your-firebase-init-on-android-ojner0y4k#faq","mainEntity":[{"@type":"Question","name":"How do I disable FirebaseInitProvider so I can manually initialize Firebase on Android?","acceptedAnswer":{"@type":"Answer","text":"Override the FirebaseInitProvider entry in your app's AndroidManifest.xml using a node marker that sets tools:node to \"remove\", which prevents Android build tools from merging the provider into your app. You must also declare the tools namespace in the manifest root tag if it isn't already present.
