推荐答案

您想使用它吗?

如果是Global，则可以在课后声明

what dou you want to use it?

If Global you can declare after the class

>public class MainActivity extends Activity {
 
    String IMEI="";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
 
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}
