Whats wrong with my code? Why I get such error on card view, which is line 71. I still cannot find a solution, while i implement same as tutorials. Please help if possible. i added some properties, removed some.no influence and same error over and over again

Answer 1

In React-native you need to force the same version for appcompat in your gradle.build,

configurations.all {
    resolutionStrategy {
        force 'com.android.support:appcompat-v7:23.4.0'
    }
}

Answer 2

Have you added the CardView dependency in your module's build.gradle file? Make sure you have it because it's the same exception you get when you forget including it.

compile 'com.android.support:cardview-v7:21.0.+'
