NoClassDefFoundError while loading activity

While loading my app throws this error, then displays the layout normally. How can I stop it from throwing this error? Happens on both android 8 and android 6.

Could not get unknown property 'resolutionStrategy' for project ':app' of type org.gradle.api.Project

I was getting this error:
Error:Execution failed for task ':app:preDebugBuild'.
Android dependency 'com.android.support:appcompat-v7' has different version for the compile (25.3.1) and runtime (27.1.0) classpath. You should manually set the same version via DependencyResolution
A quick search on google showed me that I should include in my app/build.gradle:
resolutionStrategy.eachDependency { details ->
if (details.requested.group == 'com.android.support'
&& !details.requested.name.contains('multidex') ) {
details.useVersion "25.3.1"
}
}

You have updated your sdk with project change : import android.support.v7.app.ActionBarDrawerToggle; remove import android.support.v4.app.ActionBarDrawerToggle;
