Manifest merger failed : uses-sdk:minSdkVersion 14 cannot be smaller than version 21 declared in library [com.github.codeestX:ECardFlow:v1.0.5] C:\Users\Admin.android\build-cache\cffbe8107ef245ed24c175848464f3a6634f9f9b\output\AndroidManifest.xml
Suggestion: use tools:overrideLibrary="moe.codeest.ecardflow" to force usage

can you please downgrade sdk version to 14..??

Update gradle file same as your app.gradle file.. both file needs to be on same sdk and target version..
like:
Build.gradle

apply plugin: 'com.android.library'
// JitPack Maven
//apply plugin: 'com.github.dcendents.android-maven'
// Group
//group='com.github.codeestX'

android {
    compileSdkVersion 28
    buildToolsVersion '27.0.3'

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation 'com.android.support:appcompat-v7:25.1.0'
    testImplementation 'junit:junit:4.12'
}

app.gradle

apply plugin: 'com.android.application'

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

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
