The fact is that when I create a project when adding any component to the preview interface it does not let me see it, it only lets me see it if I execute the application in an emulator. Then I will leave a photo so it can be clearer. If anyone knows the solution, it would be very helpful. Thanks in advance.
To me it happens exactly the same and I do not know what the error is, in order to solve it in the gradle I am using version 27 or lower so it shows me the previsualizacion you would have to change also all the implementations of the dependencies to version of sdk 27 I put you an example
pply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
applicationId "asd.movimientolist"
minSdkVersion 22
targetSdkVersion 27
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(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:27.0.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
implementation 'com.android.support:support-v4:27.0.1'
implementation 'com.android.support:recyclerview-v7:27.0.1'
implementation 'com.android.support:cardview-v7:27.0.1'
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'
implementation files('src/main/java/ksoap2.jar')
}
If the build does it correctly, it should be visible, anyway you can try the following:
- Build -> Clean Project,
- Build -> Rebuild Project
If it still does not work, close the emulator and
Files -> Invalidate Caches / Restart
If the error persists, try reinstalling or even updating IDE to a stable version.
