CodePudding user response：

What worked for me is to change the gradle version in /android/build.gradle

classpath 'com.android.tools.build:gradle:7.1.2'

and Distribution Url

distributionUrl=https\://services.gradle.org/distributions/gradle-7.2-all.zip

Also Change your minSdkVersion to 21

CodePudding user response：

First:- Implement these changes

classpath 'com.android.tools.build:gradle:7.1.2'

distributionUrl=https\://services.gradle.org/distributions/gradle-7.2-all.zip

Second is these:-

Add android:exported="true" in AndroidManifest.xml inside activity tag

And last is this:-

implementation "androidx.multidex:multidex:2.0.1"

CodePudding user response：

you should add this in

android/app/build.gradle

lintOptions { checkReleaseBuilds false }
