How to fix Execution failed for task ':app:processDebugManifest'

Question

I am facing this after installing react native image picker when using the npx react-native run-android command.

D:\WEB SAYLANI\React Native CLI\AwesomeProject>npx react-native run-android info Running jetifier to migrate libraries to AndroidX. You can disable it using "--no-jetifier" flag. Jetifier found 1222 file(s) to forward-jetify. Using 4 workers... info JS server already running. info Installing the app...

Change the minSdkversion 21. You can change it from android/build.gradle directly Open the project go to the android folder and open build.gradle file. In this you can find

buildscript {
    ext {
        buildToolsVersion = "29.0.2"
        minSdkVersion = 21
        compileSdkVersion = 29
        targetSdkVersion = 29
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:3.5.3")
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
