我认为需要我的build.gradle，所以这是我的build.gradle(Project:test):

And I think my build.gradle is needed so here is my build.gradle(Project: test): 

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

android {
    compileSdkVersion 27
    buildToolsVersion '28.0.3'
    defaultConfig {
        applicationId "com.test.notes.notes"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 17
        versionName "5.1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    lintOptions {
        checkReleaseBuilds false
    }
    aaptOptions {
        cruncherEnabled = false
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.0.2'
    implementation 'com.android.support:design:27.0.2'
    implementation 'com.android.support:cardview-v7:27.0.2'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:support-v4:27.0.2'
    implementation 'com.android.support:support-vector-drawable:27.0.2'

    implementation 'com.google.firebase:firebase-firestore:15.0.0'

    api 'com.joooonho:selectableroundedimageview:1.0.1'
    api 'com.github.bumptech.glide:glide:3.7.0'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'

    api 'com.crashlytics.sdk.android:crashlytics:2.9.5'
}

apply plugin: 'com.google.gms.google-services'

出现该错误，应用崩溃.
我认为firebase SDK可能有什么问题，但无法弄清楚吗?
请帮助我解决此问题.很长时间以来，我都没有找到解决它的方法.:(

With that error, the app crashes.
I think there could be anything wrong with the firebase SDK, but can't figure it out?
Please help me to fix this. I didn't find a way to fix it, for a long time.:(


将所有内容更新到最新版本并添加后:


After updated everything to the newest version and added: 

multiDexEnabled true

...一切正常.但是现在我有了问题，为什么我最终将版本降级了.请看一下我的问题:我没有得到答复:
在Firebase 16.0.+更新后更新代码

...everything works fine. But now I have the Problem, why I downgraded the versions finally. Please have a look at my question: I don't get a response:
Updating code after firebase 16.0.+ update

我可以解决的话，一切都会好起来的.

When I could fix that everything would be fine.

推荐答案

我在您的 build.gradle 中看到了很多问题.

I see a whole mess of problems in your build.gradle.

第一类问题是您的大多数依赖项已经过时了.

The first category of issues is that most of your dependencies are pretty outdated.

  • Android API 27支持库位于27.1.1，而不是27.0.2.
  • firebase-firestore 位于17.1.2，而不是15.0.0.
  • firebase-ui-firestore 位于4.2.1而非2.1.1.上.
  • glide 位于4.8.0，而不是3.7.0.
  • The Android API 27 support libraries are on 27.1.1, not 27.0.2.
  • firebase-firestore is on 17.1.2, not 15.0.0.
  • firebase-ui-firestore is on 4.2.1, not 2.1.1.
  • glide is on 4.8.0, not 3.7.0.

从属版本通常应该是最新的，但是如果它们来自Google，则绝对 必须是最新的.否则，您将碰到您所遇到的错误类型.

Dependency versions should be up-to-date in general, but absolutely must be up-to-date if they're from Google. Otherwise you run into exactly the type of error you have.

第二个问题是您两次实施 firebase-firestore ，一次是通过 implementation 实施，另一次是通过 api 实施.删除其中一个.

The second problem is that you implement firebase-firestore twice, once with implementation and again with api. Remove one or the other.

一个方便的提示:如果依赖项以黄色突出显示，则表示它已经过时了！单击文本，单击 + 并选择将其更新为最新版本的选项.

A handy tip: if a dependency is highlighted in yellow, that means it's outdated! Click the text, hit + and choose the option to update it to the latest version.
