Answer 1

I had some problems as you say in recently. And I resolve these problem as follow:

Step 1. Create a new android project in AndroidStudio , and it can run normally.

Step 2. Please make sure your project can run normally, and see the build.gradle file， then find the version code in build.gradle file. And my build.gradle file like as follow:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion 24.0.1
}
...
...
dependencies {
    // App's dependencies, including test
    compile "com.android.support:appcompat-v7:23.4.0"
    compile "com.android.support:cardview-v7:23.4.0"
}

And the correct version 23.4.0 is what you want.

If you can not solve the problem, you can change compileSdkVersion and buildToolsVersion.

Step 3. Config the correct version in your build.gradle file and sync project.
