java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v7/appcompat/R$styleable

Question

I am new with ActionBarActivity, my application get crashed while running following code in eclipse public class Login extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);
    if (savedInstanceState == null) {
        getSupportFragmentManager().beginTransaction()
        .add(R.id.container, new PlaceholderFragment()).commit();
    }

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.login, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

/**
 * A placeholder fragment containing a simple view.
 */
public static class PlaceholderFragment extends Fragment{

    public PlaceholderFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_login,
                container, false);
        return rootView;
    }
}

}

Where I already import

import android.support.v4.app.Fragment;

import android.support.v7.app.ActionBarActivity;

but still I got an errors in LogCat as follows:

You should use #Android Studio instead of Eclipse .

NoClassDefFoundError error is thrown when the Java Virtual Machine (JVM) or an instance of the ClassLoader class tries to load the definition of a class, but the definition could not be found.

Bad Approach : Using Deprecated Code (ActionBarActivity).

At first extends AppCompatActivity instead of ActionBarActivity .

public class Login extends AppCompatActivity {
  // ...
}

Advice

set android:minSdkVersion version .

<uses-sdk android:minSdkVersion="15" />

Try this way ,Hope it woks .

Install android support package in Android SDK Manager Android SDK Manager
Add AppCompatActivity package to your gradle config

compile 'com.android.support:appcompat-v7:23.1.0'
Check min SDK version
