The plugin requires a higher Android SDK version

[amrf93]

Flutter: 3.22.3
Android Studio version: 2023.2
Firebase Component: Auth (Database, Firestore, Storage, Functions, etc)
Firebase Auth: 5.1.4

I have an error after I added Firebase Auth plugin:

The plugin firebase_auth requires a higher Android SDK version.
Fix this issue by adding the following to the file C:\Users\HP\Desktop\app\test_i\android\app\build.gradle: │
android {
defaultConfig {
minSdkVersion 23
}
}
Following this change, your app will not be available to users running Android SDKs below 23. │
Consider searching for a version of this plugin that supports these lower versions of the Android SDK instead.

But when I went to build.gradle I found it like this:
defaultConfig { applicationId = "com.example.test_i" minSdk = flutter.minSdkVersion targetSdk = flutter.targetSdkVersion versionCode = flutterVersionCode.toInteger() versionName = flutterVersionName }

I;ve tried to replace flutter.minSdkVersion with 23, like this:
defaultConfig { applicationId = "com.example.test_i" minSdk = 23 targetSdk = flutter.targetSdkVersion versionCode = flutterVersionCode.toInteger() versionName = flutterVersionName }

But it didn't work either, and gave me another error:

Launching lib\main.dart on sdk gphone x86 in debug mode...
Running Gradle task 'assembleDebug'... 7.8s
√ Built build\app\outputs\flutter-apk\app-debug.apk

Any help, guys?

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @amrf93, thank you for reaching out. Could you try cleaning up your build by running flutter clean and rebuild your app?

In addition to that, I recommend modifying the flutter.minSdkVersion declared in the local.properties file of your app. To streamline the change.

Thank you @lehcar09 for your time. I've tried that, but it didn't work. Any other tips?

Hey @amrf93, pardon me, just to clarify, does the issue The plugin firebase_auth requires a higher Android SDK version. persist after you replace the flutter.minSdkVersion with 23?

Looking into the second error you shared, the APK file was build and that means the minSdkVersion is resolved.

The second error Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE] you encountered is not related with the first error. This error indicates that the Android Debug Bridge (ADB) encountered an issue while trying to install your app on the emulator or device. This could be resolved by freeing up a space on the device or emulator. You can check on this similar issue #4508 filed in the Flutter repository.

It was the first problem that led to the second; because before installing the firebase_auth plugin, I had no problem.
I did not find the solution in the topic #4508 you sent me. But it made me realize the new problem.

So I looked for other solutions to it. I tried many of them and finally found the solution:

• 1st error: Change "minSdk = flutter.minSdkVersion" to "minSdk = 23". For me, it was 23, and it's the same SDK version given in the error.
• 2nd error: Increase the internal storage of my emulator through AVD, from 6 to 10 GB.

Last but not least, thank you @lehcar09, you have been a great help.
