问题出现的原因:

Android studio升级到3.0以上,工程自动会引入Androidx的相关包,当因为某些原因,我们把默认依赖删除以后,就会出现 Android resource linking failed ,错误日志1是缺少 androidx.appcompat:appcompat:1.0.0-alpha1 依赖,错误日志2是缺少 androidx.constraintlayout:constraintlayout:1.1.2 依赖,

错误日志3是因为 compileSdkVersion 版本不对,应该改为 compileSdkVersion 28

解决方案

添加相关依赖即可,如下:

implementation 'androidx.appcompat:appcompat:1.0.0-alpha1'
implementation 'androidx.constraintlayout:constraintlayout:1.1.2'

二. java.lang.ClassNotFoundException

                ... 15 more

原因分析:

build.gradle文件如下

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.hp.temp"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
//    implementation 'androidx.appcompat:appcompat:1.0.0-alpha1'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.2'
    implementation 'com.android.support:appcompat-v7:27.1.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.0-alpha3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha3'
    implementation 'com.blankj:utilcode:1.15.0'
}

原因我依赖了 implementation 'com.blankj:utilcode:1.15.0' ,其中有个 FileProvider 类找不到,如下: 

package android.support.v4.content;

import android.support.annotation.Keep;

/**
 * <pre>
 *     author: Blankj
 *     blog  : http://blankj.com
 *     time  : 2018/04/23
 *     desc  :
 * </pre>
 */
@Keep
public final class FileProvider4Util extends FileProvider {
}

由于androidx的使用,架包的分包方式发生了变化, com.android.support:support-v4 被 androidx.core 代替,但是 utilcode 架包中并没有使用androidx分包结构,所以就存在问题.

解决方案:

1.不使用androidx分包,将

<code>implementation 'androidx.appcompat:appcompat:1.0.0-alpha1'</code>
<code>  implementation 'com.android.support:appcompat-v7:27.1.1'</code>

虽然后报红,但是不会报错

2.重构到新的androidx命名空间
