Android Annotation Processing Tutorial: Example Project

A complete library implementation

Annotation processing has become one of the most important language features in the modern Java programming. Java supports annotation processing from the release of Java 5 but its full potential has been realized in the recent years. Annotation processing in simple words is used to generate files during compilation.

Can not generate binding source for inner class

When i change MainActivity for testing
public class MainActivity extends AppCompatActivity {

@BindView(R.id.tv_content)
TextView tvContent;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Binding.bind(this);
}

@OnClick(R.id.bt_1)
void bt1Click(View v) {
    tvContent.setText("Button 1 Clicked");
}

@OnClick(R.id.bt_2)
void bt2Click(View v) {
    tvContent.setText("Button 2 Clicked");
}
public class TestActivity  extends AppCompatActivity{
    @BindView(R.id.tv_content)
    TextView tvContent;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Binding.bind(this);
    }
}

}
Have no file "MainActivity$TestActivity$Binding.java" is created.
How can I inject for inner class?

When I ran the app, it crashed. Here is the error log.
