Я каждый день сталкиваюсь с очень неприятной проблемой ConstraintLayout в моем проекте.
Файл градиента проекта:
buildscript {
ext.support_library_version = '27.0.2'
ext.play_services_version = '11.6.2'
ext.firebase_version = '11.6.2'
repositories {
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'io.realm:realm-gradle-plugin:4.2.0'
classpath 'com.google.gms:google-services:3.1.2'
classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.7.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
google()
maven { url "https://maven.google.com" }
maven { url 'https://jitpack.io' }
}
}
Это моя короткая версия приложения gradle:
apply plugin: 'com.android.library'
apply plugin: 'realm-android'
// set to 'cmake', 'none'
def nativeBuildSystem = 'none'//'cmake'
realm {
syncEnabled = false
}
android {
defaultConfig {
targetSdkVersion 27
compileSdkVersion 27
minSdkVersion 21
// for using vectors for less than 21 API
vectorDrawables.useSupportLibrary = true
versionCode 56
dexOptions {
preDexLibraries true
javaMaxHeapSize "4g"
}
// Enabling multidex support.
multiDexEnabled true
versionName "1.6.5"
renderscriptTargetApi 2
renderscriptSupportModeEnabled true // Enable RS support
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
configurations {
all*.exclude group: 'commons-logging', module: 'commons-logging'
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')

Ниже то, что я вижу в редакторе макетов:
Ниже моего xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.constraint.ConstraintLayout>
Редактор макетов в этом случае говорит:
И если я нажму Показать исключение, я увижу:

Я много пробовал, чтобы решить ее, но безуспешно. Я не решил, используя простые подходы, такие как аннулирование кеша/очистка проекта/перестроение проекта и т. д.
