Firebase-crash version and firebase-perf version must be lesser than or equal to the Firebase-core version so In your code just change the Firebase-crash:16.0.1 version to Firebase-crash:16.0.0 and firebase-perf:16.1.0 version to firebase-perf:16.0.0 Because your's firebase-core version is 16.0.1
compile 'com.google.firebase:firebase-perf:16.0.0'
compile 'com.google.firebase:firebase-crash:16.0.0'
I had the same problem, although Siva Kumar's solution worked, what also worked for me was to use the latest google-services library on your project build.gradle :
dependencies {
classpath 'com.google.gms:google-services:4.1.0'
}
For me none of the other solutions worked. Very frustrating, the application didn't even start. Finally I removed Performance Monitoring:
//apply plugin: 'com.google.firebase.firebase-perf'
//implementation 'com.google.firebase:firebase-perf:16.1.2'
