punit das :
i am trying to integrate firebase to my android project but constantly getting error of "In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[17.0. 4]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.
Dependency failing: com.google.firebase:firebase-messaging:17.3.4 -> com.google.firebase:firebase-iid@[17.0.4], but fire base-iid version was 20.0.2."
my code for the app gradle build is-------
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.goldfish"
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 {

}
Bob Snyder :
