How to lower compile SDK version in Android Studio so that the app still function correctly










0















I'm building an app for my project. First, here is my module app gradle:



apply plugin: 'com.android.application'

android
compileSdkVersion 26
defaultConfig
applicationId "com.huyhuyhuygmail.mynewproject"
minSdkVersion 19
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

buildTypes
release
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'


productFlavors



dependencies
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:26.+'
implementation 'com.android.support:design:26.+'
implementation 'com.android.support:cardview-v7:26.+'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
implementation 'com.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
implementation 'com.google.firebase:firebase-core:16.0.4'
implementation 'com.google.firebase:firebase-database:16.0.3'
implementation 'com.google.android.gms:play-services-maps:16.0.0'
implementation 'com.google.android.gms:play-services-location:16.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'


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


I have 2 Android devices, one runs on Android 4.4.4 and the another runs on Android 5.1.1. When I use these devices to test my app, the bottom navigation bar and some drawable/views in my app just keep disappearing.
When I use Genymotion emulator with API 26 virtual device, the bar and other layouts are fine but the emulator seems doesn't work correctly with Google Map API, so that I can't use these emulators to run my app.



Is there anyway to lower the compile SDK version so that I can run the app smoothly on my Android devices?
