I have been using android support v4 23.1.1 and recently tried to update it to 23.3.0 ( the latest one when this was asked) but I got the following error:

Answer 1

For me, The build tool version has to align with the dependency versions. So lets say the build tool version is 26.1.0, the Gradle dependency version has to obey it.

The simplest way is to create a version variable & use it. See the example below

ext {
    buildVersion = '26.1.0'
}

dependencies {
    compile "com.android.support:appcompat-v7:${buildVersion}"
}
