Android：在哪里可以找到此LogCat错误的解决方案？

时间：2013-11-14 14:25:59

标签： android nullpointerexception logcat

当我的应用程序统计时，我收到此错误，如下所示（不是每次，只是时不时）。有没有人可以告诉我在哪里可以搜索此错误的问题？我甚至不知道我的代码的哪一部分导致了nulpointerexception错误。

该应用程序显示崩溃，说该应用已停止，但它仍然在菜单上移动..

出现的顺序应该是：IntroScreen（闪屏3秒） - 带有选项的菜单屏幕可以转到其他屏幕。

Introscreen.java：

public class IntroScreen extends Activity {

private final int SPLASH_DISPLAY_LENGHT = 3000; 
public final static String EXTRA_MESSAGE = "com.example.emmtec.MESSAGE";

@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.activity_intro_screen);


    new Handler().postDelayed(new Runnable(){
        @Override 
        public void run() {
            Intent mainIntent = new Intent(IntroScreen.this,MenuScreen.class);
            mainIntent.putExtra(EXTRA_MESSAGE, "begin");
            IntroScreen.this.startActivity(mainIntent); //start menu scherm
            IntroScreen.this.finish(); //stop intro scherm
        }
    }, SPLASH_DISPLAY_LENGHT); //na 3000 ms.
}
}
