I started developping android apps with android studio (java) a few months ago.

My current app is called MyAverage and I have several versions of it, each one within a new project. Sadly I didn't know that they shouldn't have the same app id and now whenever I install/launch my newest version from within android studio on my mobile phone I get multiple MyAverages on my phone even if I uninstalled/deleted the other versions before.

Is there any way how I can fully remove the old MyAverages from my phone that I don't need and use anymore?

In Your app level build.gradle Change application Id

android {
    compileSdkVersion 32
    buildToolsVersion "30.0.3"

    viewBinding {
        enabled = true
    }

    defaultConfig {
        applicationId "com.test.myapp.package"
        //Change your package name from here it will generate different package name apk for you
        minSdkVersion 23
        targetSdkVersion 32
        versionCode 67
        versionName "0.6.7"
        javaCompileOptions {
            annotationProcessorOptions {
                arguments  = ["room.schemaLocation":
                                      "$projectDir/schemas".toString()]
            }
        }
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
        debug {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_11
        targetCompatibility JavaVersion.VERSION_11
    }

    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_11.toString()
    }

}
