I started a project in android studio 3.1.3 and when I want to design something in the activity design palette, there is a problem! figure below: render errors
This is my gradle(Module: app) code:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.mohammad.myapplication"
minSdkVersion 14
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'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
implementation 'com.android.support:design:28.0.0-alpha3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
I thought maybe this could help: In my Sdk folder, in build-tools folder, there is two folders 28.0.1 & 27.0.3
Update:
I tried these and got nothing:
- invalidate caches/restart
- changing alpha3 to alpha1
- running on an emulator (there were no errors, it's working well)
