任何帮助都将非常感激！

更新

这是splash.java上的代码

public void run() {
            try {

                Thread.sleep(3000);

                Intent i = new Intent();
                i.setClassName("aladin888.dessin",
            Line 49---------------->            "aladin888.dessin.EasyPaint");
                startActivity(i);
                finish();

            } catch (Exception e) {
e.printStackTrace();

它应该只是EasyPaint吗？
