Question & Answer :
I was making an attempt to commencement a flutter task for an App utilizing Bluetooth to pass. For that, I was utilizing flutter bluish.
Unluckily, once attempting to tally (connected an Android instrumentality) the archetypal illustration I created I was met with the pursuing mistake:
Nonaccomplishment: Physique failed with an objection. * What went incorrect: Execution failed for project ':app:processDebugManifest'. > Manifest merger failed : makes use of-sdk:minSdkVersion sixteen can't beryllium smaller than interpretation 19 declared successful room [:flutter_blue] /location/maldus/Tasks/flutter/polmac/physique/flutter_blue/intermediates/manifests/afloat/debug/AndroidManifest.xml arsenic the room mightiness beryllium utilizing APIs not disposable successful sixteen Proposition: usage a suitable room with a minSdk of astatine about sixteen, oregon addition this task's minSdk interpretation to astatine slightest 19, oregon usage instruments:overrideLibrary="com.pauldemarco.flutterblue" to unit utilization (whitethorn pb to runtime failures)
If I have been connected Android Workplace, I’d cognize however to bump ahead the Android minSdkVersion, however connected a Flutter task (utilizing VSCode) I was a small mislaid.
Is it imaginable to addition the minSdkVersion with Flutter, and however?
It is so imaginable to addition minSdkVersion, however it took maine manner excessively overmuch clip to discovery it retired due to the fact that google searches largely yields arsenic consequence discussions astir the implicit minimal Sdk interpretation flutter ought to beryllium capable to activity, not however to addition it successful your ain task.
Similar successful an Android Workplace task, you person to edit the physique.gradle record. Successful a flutter task, it is recovered astatine the way ./android/app/physique.gradle.
The parameter that wants to beryllium modified is, of class, minSdkVersion sixteen, bumping it ahead to what you demand (successful this lawsuit 19).
defaultConfig { // TODO: Specify your ain alone Exertion ID (https://developer.android.com/workplace/physique/exertion-id.html). applicationId "com.illustration.projectname" minSdkVersion 19 //*** This is the portion that wants to beryllium modified, antecedently was sixteen targetSdkVersion 28 versionCode 1 versionName "1.zero" testInstrumentationRunner "android.activity.trial.runner.AndroidJUnitRunner" }
Appears apparent present, however took maine agelong adequate to fig it retired connected my ain.
