I tried 1. clean and rebuild 2. invalidate caches and Restart 3. changing gradle dependencies and this what android studio suggested Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights. And even tried this

Gradle(project)

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

“I expect the output of smooth run, Please Help" Thanks in advance

Answer 1

Build > Clean Project

Or

./gradlew clean build

Or

In the individual apps's build.gradle section android {}, insert :

aaptOptions {  
    cruncherEnabled = false  
}

Answer 2

Check the file: res\drawable-v24\ic_launcher_foreground.xml

Your error says it's not well formed. It means that there are some syntax error or typo or missing brackets or maybe no images.
