问题描述
我收到此错误
更新错误:
E/AndroidRuntime: FATAL EXCEPTION: main

当我尝试运行此代码时
PhoneAuthProvider.getInstance().verifyPhoneNumber(
phoneNumber, // Phone number to verify
60, // Timeout duration
TimeUnit.SECONDS, // Unit of timeout
this, // Activity (for callback binding)
mCallbacks); // OnVerificationStateChangedCallbacks
在应用 build.gradle 中
In app build.gradle
implementation 'com.google.firebase:firebase-database:11.6.0'
implementation 'com.google.firebase:firebase-auth:11.6.0'
为什么说它是空的?什么是空?我在 Android 设备 Android 6.0 版上运行它.是不是因为手机没有sim卡?我已经在控制台中启用了电话身份验证，并且它可以在 iOS 上运行.
Why is it saying it's null? What is null? I'm running it on android device Android version 6.0. Is it because there's no sim card on the phone? I've already enabled phone authentication in the console and it's working on iOS.
更新:
更新 firebase-core 和 firebasse-auth 版本后，应用不再崩溃.
After Updating the version of firebase-core and firebasse-auth, the app doesn't crash any more.
implementation 'com.google.firebase:firebase-core:16.0.5'
implementation 'com.google.firebase:firebase-auth:16.0.5'
发现它是由我正在测试的手机的 8.3.01 (2385995-434) 版 Google Play 服务引起的.有什么解决方案可以使其与 8.3.01 一起使用?
Found out it's caused by version 8.3.01 (2385995-434) Google Play services of the phone I'm testing on. Any solution to make it work with 8.3.01?
错误:
" W/GooglePlayServicesUtil:Google Play 服务已过时.需要 12451000 但找到 8301434"
" W/GooglePlayServicesUtil: Google Play services out of date. Requires 12451000 but found 8301434"
问题:
如何控制最低 Google Play 服务版本?
How to control the min Google Play services version?
推荐答案
你可以看看这个工作代码.
You can have a look at this working code.
build.gradle(应用级)
dependencies {
implementation 'com.google.firebase:firebase-core:16.0.5'
implementation 'com.google.firebase:firebase-auth:16.0.5'
}
build.gradle(项目级)
buildscript {
dependencies {
classpath 'com.google.gms:google-services:4.1.0'
}
}
