Error: Program type already present: android.arch.lifecycle.LifecycleRegistry$1
com.firebaseui:firebase-ui-firestore:3.1.0 depends on android.arch.lifecycle:extensions:1.0.0-beta1. Switching to version 3.2.2 fixes the issue by using the Lifecycle 1.1 libraries that Support Library 27.1.0 are built upon.
解决方案:
Try to replace all '27.1.0' with '27.0.2'(同时也将所有28.0.0改成27.0.2)
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.c00369690.myapplication"
minSdkVersion 27
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
