After I reinstalled Android Studio, many resources are kinda missing

Question

I reinstalled Android Studio, because one of my drives crashed. After the installation I tried to build my project, I got some strange errors:

I cleaned my cache and tried to build again, but I get the same errors. Has anyone experiences with this error?

UPDATE:
If I delete the file \app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml the error is gone. But just for a few minutes. Then I have to delete the file again. And everytime I start Android Studio I have to reselect my SDK. These Errors are really strange.

Answer 1

This is because you have different version of CompileSdkVersion, buildToolsVersion, targetSdkVersion, and support library. You need to use the same version for them. In your case, you need to use version 27. Something like this:

apply plugin: 'com.android.library'

android {
  compileSdkVersion 27
  buildToolsVersion "27.0.3"

  defaultConfig {
    minSdkVersion 14
    targetSdkVersion 27
    // ...
  }

  //...
}

dependencies {

  // ...
  implementation 'com.android.support:appcompat-v7:27.1.0'

}
