Минимальная версия SDK и совместимость с API

Я новичок на форуме, только что зарегистрировался. Я аргентинец, так что, возможно, моя грамматика не идеальна, но я постараюсь сделать меня понятным. Дело в том, что год назад я делал приложение на студии Android, и мы с другом остановились по нескольким причинам. Теперь у нас есть время, чтобы закончить его, но есть проблема с градиентом проекта, и я помню, что решил ее тогда. Дело в версиях api, которые я использовал, и в версиях SDK. Во-первых, приложение должно поддерживаться на большом количестве устройств, и нам не нужно много нового. Итак, мы стремимся получить самый популярный SDK, насколько это возможно (однако нам действительно нужно использовать API, которые я перечислю ниже).

Мы использовали SDK 26, и на тот момент проект был правильно построен. Теперь студия Android рекомендовала обновить до SDK 28, и я попытался это сделать, но все равно не удалось Я перечислю API и SDK, которые у меня есть на данный момент: (не забудьте рекомендовать популярную версию SDK и версии API этого SDK)

apply plugin: 'com.android.application'

android {
compileSdkVersion 28
buildToolsVersion "28.1.0"
defaultConfig {
applicationId "com.example.xxxxxxxx.xxx"
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunne r"
}

buildTypes {

rules.pro'
}
}

androidTestCompile('com.android.support.test.espre sso:espresso-core:2.2.2',

exclude group: 'com.android.support', module: 'support-annotations'
})

compile 'com.google.gms:google-services:3.2.0'
compile 'com.google.android.gmslay-services-auth:16.0.1'
testCompile 'junit:junit:4.12'
}
}

apply plugin: 'com.google.gms.google-services'
apply plugin: 'maven'

Извините, если это вопрос новичка или если я не смог найти место в ветке, но было бы очень полезно, если бы мне кто-то помог. Мое почтение, Xrless.
