Answer 1

Had a similar problem, to fix this in Android Studio (AS) I went Build->Clean Project and AS sorted everything out. Make sure in your build.gradle file under dependencies that you have:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:your_api_version_number.0.0'
    compile 'com.android.support:design:+'
}

I solved the issue Manually by adding the following two lines:

implementation 'com.android.support:support-v4:22.2.0'
implementation 'com.android.support:design:22.2.0'

under dependencies in \app\build.gradle worked for me.

Note: Your all the support libraries have to be the same version i.e. appcompat-v7 and support-v4 to same version e.g. 23.0.1; otherwise you can get this error
