I\'m in an android programming class and I am trying to add an action bar to my app.

The actionbaractivity shown below is underlined in red saying it cannot resolve the symbol. From what I understand I have to add a dependencies in the build.gradle. I imported this project and there does not seem to be one in it. Is there a way for me to add a build.gradle or something similair. Thanks in advance.

Solution

Step 1

Open your SDK manager and make sure that \"Android Support Repository\" is installed. If not select the option and Install packages. You will fins your Support repository here

SDK_DIR\\extras\\android\\m2repository\\com\\android\\support\\appcompat-v7

Step 2

In main module, open build.gradle file and add the dependency for action bar.

dependencies
{
compile \'com.android.support:appcompat-v7:+\'
}

Step 3

Sync your project with gradle through
Tools-> Android-> Sync Project With Gradle Files

Relauch your Android studio to sync your project with gradle.
