I have generated a signed APK for my application

here is the build.gradle 

android {
        compileSdkVersion 28
        defaultConfig {
            applicationId "com.example.test_drivers"
            minSdkVersion 19
            targetSdkVersion 28
            versionCode 1
            versionName "1.0"
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            }
        }
    }

And I have checked both V1 and V2. The app is installed perfectly in version 8 but not in version 9.

Any Idea how to solve this?

  • check if you already have a debug build on the phone that you are trying to install the signed apk. If the phone already has debug or release build(unsigned), uninstall that build then install the signed apk. – Akhil Soman Aug 29 '19 at 11:06

  • @AkhilSoman I have already checked that – rav Aug 29 '19 at 11:48
  • @RicardoA. I checked it , that's why I'm asking – rav Aug 29 '19 at 11:48
  • Can you see any errors in the logcat when you try to install? THere should be a message explaining why it cannot install. – David Wasser Aug 30 '19 at 15:25
