Compatibility of api 22 with api 19

Navigation
1

I generated an application which runs very well on systems with api levels higher than 20, I wanted to try an android s4 mini which has an api level 19 (Kit-Kat) someone can help me to give compatibility with this system.

I have reviewed some tutorials which led me to modify the project structure and modify compilesdk to version 19. but I have a problem with these two lines of gradle code 

compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'

Try changing the first dependency to your verion 19.4.0 ie: 

compile 'com.android.support:appcompat-v7:19.4.0'

and I have no problems but I can not do the same with the second dependcia. Can anybody help me. The application works with the navigation drawer component

This is my complete gradle file 

apply plugin: 'com.android.application'

android {
compileSdkVersion 19
buildToolsVersion "24.0.2"
defaultConfig {
    applicationId "com.example.kevtho.aplicacion"
    minSdkVersion 19
    targetSdkVersion 19
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
productFlavors {
}
}

dependencies {
compile 'com.android.support:appcompat-v7:19.4.0'
compile 'com.android.support:design:23.4.0'
compile('com.android.support:support-v4:23.4.0') {
    exclude group: 'com.android.support', module: 'support-v4'
}
compile 'com.google.android.gms:play-services:9.4.0'
testCompile 'junit:junit:4.12'
compile 'com.android.support:support-v4:23.2.1'
compile files('libs/btsdk.jar')
compile files('libs/gson-2.2.4.jar')
//compile files('libs/android-support-4.0.jar')
}

I could already solve the problem, it turns out that the compatibility problem occurred because in my project I use multidex, the solution was to add dependencies of this class to the project's grade. Here I share the detailed information.

You do not need to change the dependencies: 

compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'

If you want your application to be supported for devices with Android API 19 simply define: 

 minSdkVersion 19

and do not change compileSdkVersion and buildToolsVersion you can use a version according to the dependencies that you have defined 

android {
compileSdkVersion 24
buildToolsVersion "23.0.3"

the same for targetSdkVersion : 

targetSdkVersion 23

If I'm not going wrong, what limits the app can run is the minSdkVersion=19 the compileSdkVersion you indicate with which SDK you want to compile the project.

I suppose that the second dependency that you refer is to the com.android.support:dessign:23... is normal that you can not put it to 19, since it did not exist then, Google the sac to give compatibility to the API of Lollipop for previous versions.
