Support for actionbar v7 android

Question

IDE : Android Studio

• Create a new project
• Copy .jar appcompat using / lib /
• Set dependencies in project settings
• Add compilation "com.android.support:appcompat-v7:18.0.+" to build .gradle

• Add the following code:

  public class MainActivity extends ActionBarActivity {

  @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ActionBar actionBar = getSupportActionBar(); actionBar.setTitle("hello"); } 

And nothing. Get the following error:

 "Gradle: A problem occurred configuring project ':MyApplication'. > Failed to notify project evaluation listener. > Could not resolve all dependencies for configuration ':MyApplication:_DebugCompile'. > Could not find any version that matches com.android.support:appcompat-v7:18.0.+. Required by: MyApplicationProject:MyApplication:unspecified" 

How to fix? What did I forget to do?

Answer 1

you need to install support repository

3. Select the Android Support Libraries item.

Note. If you are using Android Studio, select and install the Android Support Repository Element. http://developer.android.com/tools/support-library/setup.html

Answer 2

Try importing the library, not copying it.

Also include:

 actionBar.setDisplayShowTitleEnabled(true);
