有人可以帮助我解决这个错误。首先，我遇到了设计XML文件的问题。我没有进一步为我的android studio version3.0.1创建一个练习项目。面对这个问题所以guyz帮助我完全解决方案

我在实现中看到您混合了支持库版本。不要那样做。这将导致错误。始终为支持库使用一个特定版本。混合会导致错误。试试这个：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.rahul.expensemanager"
        minSdkVersion 19
        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'
        }
    }
}
configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == "com.android.support") {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion "28.0.0-alpha1"
            }
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
//    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.google.firebase:firebase-messaging:17.3.1'
    implementation 'com.google.firebase:firebase-auth:16.0.3'
    implementation 'com.google.firebase:firebase-database:16.0.2'
    implementation 'com.google.firebase:firebase-ads:15.0.1'
    testImplementation 'junit:junit:4.12'
    implementation 'com.firebaseui:firebase-ui-database:3.3.1'
    implementation 'com.firebaseui:firebase-ui-firestore:3.3.1'
    implementation 'com.google.firebase:firebase-core:16.0.3'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestCompile 'com.android.support:support-annotations:28.0.0-alpha1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.android.support:recyclerview-v7:28.0.0-alpha1'
    implementation 'com.android.support:support-annotations:28.0.0-alpha1'
    implementation 'com.android.support:design:28.0.0-alpha1'        
    implementation 'com.android.support.constraint:constraint-layout:2.0.0-alpha2'
    implementation 'com.android.support:cardview-v7:28.0.0-alpha1'
//    implementation "com.google.firebase:firebase-client-android:3.4.0"
}
apply plugin: 'com.google.gms.google-services'

我所做的是使用你的项目的28.0.0-alpha1版本。告诉我错误是否仍然存在。

Answer 2

似乎错误来自sdk 28 ..我建议你在app level gradle文件中更改sdk版本。

将所有依赖项更改为sdk 27

 implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'

至

   implementation 'com.android.support:appcompat-v7:27.1.1'

要么

 implementation 'com.android.support:appcompat-v7:21.1.0'

像这样改变你找到的每个依赖项

 28.0.0-alpha1 

进入这些sdk版本，然后检查，希望它会帮助你。

  and also change the sdk version to 28 to 27
