Answer by CoolMind for Error retrieving parent for item: No resource found that matches the given name after upgrading to AppCompat v23

I wanted to downgrade from API 23 to 22 and got this error. I had to change all build.gradle files in a project in order to compile.

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.yourapp.app"
        minSdkVersion 14
        targetSdkVersion 22
    }
...
dependencies {
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile 'com.android.support:support-v4:22.2.1'
    compile 'com.android.support:design:22.2.1'
    compile 'com.google.android.gms:play-services-gcm:10.0.1'
}
