java.lang.NoClassDefFoundError: Failed resolution of: Lcom/xxx/xxx/viewmodels/CameraXViewModel;

The APK is generated and everything works at compile time but app crash at runtime. The crash is when launching the camera module for barcode scanning implemented with CameraX.
Here is the crash log:

Not sure what is wrong.
Any help will be appreciated.

Solved!.
Implemented multidex from the developer site.
https://developer.android.com/studio/build/multidex
Also there were two view model classes CameraXViewModel & CameraXviewModel.kt, removed the file CameraXviewModel.kt from the project. CameraXViewModel is the one which is used and CameraXviewModel was not referenced any where in the project.
ASFAIK Java and Kotlin is case sensitive for classes, so ideally it should work. Here everything compiled and APK generated but app crashed at runtime.
Hope this helps someone.

I have a problem loading widgets in android studio

I do not know why this problem happened I opened my android studio and it does not load the view of my RecyclerView and some other widgets, since I cleaned the cache also used the Rebuild Project but the problem persists, I would appreciate your support

Just based on the dependencies, these were added correctly and the code did not move, my buildgradle structure it in this way where I use library.gradle to call the libraries by version and this is the specic code of the implementation of the RecyclerView.
ext.versions = [
supportLib : '28.0.0'
]
def version = ext.versions
ext.library = [
support_recyclerview : 'com.android.support:recyclerview-v7:' + version.supportLib
]

Use Fragment with RecyclerView and Activity host for this Fragment.

compile gradle task is always executed

I have a multidex project with minSDK 21, using gradle 4.5.1 and gradle plugin 3.0.1. My issue is that even without any source file change when I try to assemble and deploy to a phone the compile task is executed. When running with --info I get the following reasons:
Task ':app:compileStandardDebugJavaWithJavac' is not up-to-date because:
Input property 'source' file C:...\app\build\generated\source\buildConfig\standard\debug[package]\BuildConfig.java has changed.
Input property 'source' file C:...\app\build\generated\source\dataBinding\standard\debug\android\databinding\layouts\DataBindingInfo.java has changed.
Can you help my identify what could cause these files to change and causes a recompile? I believe the Databinding sources either shouldn't change without changing sources, or it shouldn't affect if the compile task is up-to-date. The same goes for BuildConfig.java.
I have gradle caching, configure on demand and daemon enabled.

It's because you're using a buildConfigField with System.currentTimeMillis(). This line causes the BuildConfig class to be updated for debug builds:
buildConfigField "java.util.Date", "buildTime", "new java.util.Date(" + System.currentTimeMillis() + "L)"
The Android Gradle Plugin updates the BuildConfig.java everytime you do a build and inserts the current Date, producing a static field similar to this one:
public static final java.util.Date buildTime = new java.util.Date(1518194256644L);
and since the time changes all the time (haha), the file has to be recompiled.

In my case, the problem was that I was appending date to version name.
def static getDate() {
return new Date().format('yyyyMMddHHmmss')
}
buildTypes {
debug {
// REMOVE THIS LINE
versionNameSuffix '-' + getDate()
applicationIdSuffix ".test"
}
The line in question was
versionNameSuffix '-' + getDate()
In case anyone else encounters the same problem.

UnsupportedOperationException The "android" command is no longer included in the SDK

I have project in Kotlin and I have updated Android Studio to 2.3.3 and gradle to 3.3 and build tools to 25.3.1. During building I got this error:
Caused by: java.lang.UnsupportedOperationException: The "android" command is no longer included in the SDK. Any references to it (e.g. by third-party plugins) should be removed.

Can someone explain to me how it works?
When i change build Variant the java content is changed. (e.g it was main, internal,internalDebug for internalDebug variant and then it became main,internal,internalRelease for internalRelease build variants).
The reason I'm asking is that i don't see any "internalRelease" word in gradle file, so i don't understand the logic of how the build variants were created and how it defines what modules to show for different build variants

debug for test without signature and release for publish with signature;click the left-top robot ,and turn android to project , u will understand;
