Publishing my first android app Supported Android devices 0 on playstore

Question

I have developed my first android app in Android Studio. I have developed a simple flashLight app. It is working well on multiple devices, but when I publish it to the playstore there is a compatibility issue. Please help me out.

Supported Android devices = 0 Devices

Build Gradle

    android {
    compileSdkVersion 23
    buildToolsVersion "24.0.0"
    defaultConfig {
        applicationId "dc.suvy.dhairya.fastflashlight"
        minSdkVersion 9
        targetSdkVersion 9
        versionCode 2
        versionName '2.0'
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}
dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'commons-io:commons-io:2.4'
}

Answer 1

Change

    minSdkVersion 9
    targetSdkVersion 9

To

    minSdkVersion 9
    targetSdkVersion 23

Also cross check if you really need these (just remove it if you have no good reason for keeping it):

    <supports-screens
    android:largeScreens="true"
    android:normalScreens="true"
    android:requiresSmallestWidthDp="720"
    android:resizeable="true"
    android:smallScreens="true"
    android:xlargeScreens="true" />

Answer 2

Your target SDK should always be the latest SDK version you can use. So just change your Build gradle to.

   minSdkVersion 9
   targetSdkVersion 23

Answer 3

Sometimes the reason for this is a third party library that you have referenced. If you can find which one is it and if you can remove it you can solve the problem.

try removing

compile 'commons-io:commons-io:2.4'
