Ahmed Elsayed :
I'm using Retrofit 2 and OkHttp3 to data from server and I get error while using Min_SDK 17 and my device's API is 17 also
I tried this answer :How to fix Expected Android API level 21+ but was 19 in Android
Also I tried this answer https://github.com/square/okhttp/issues/4597#issuecomment-461204144
but I get the same error .
my Gradle.Build class
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "some"
minSdkVersion 17
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
packagingOptions {
exclude 'META-INF/DEPENDENCIES'
}
compileOptions {
targetCompatibility = "8"
sourceCompatibility = "8"
}
lintOptions {
checkReleaseBuilds false
// Or, if you prefer, you can continue to check for errors in release builds,
// but continue the build even when errors are found:
}

MatPag :
The problem is that you have added OkHttp dependency twice.
In your build.gradle you have:
dependencies {
...
implementation "com.squareup.okhttp3:okhttp:3.11.0"
...
implementation "com.squareup.okhttp3:okhttp:3.13.1"
}
Starting with version 3.13.0 they removed support for Android < 5. You just need to delete the
implementation "com.squareup.okhttp3:okhttp:3.13.1"
line and it should work fine
