android - Ice Cream Sandwich 上的线

我在 ICS 4.0.3 上运行线程时遇到问题

我制作了 apk，并已将其安装在 2.33 SE 手机和 Google Nexus S 4.0.3 上。

在 SE 上，apk 正在按预期运行和加载。但是，在 Nexus 上我收到一个错误，我必须关闭它。但是我看到程序在后面运行。我试图从代码中删除线程(加载屏幕，启动画面)并在 Nexus 上再次运行它，它可以运行。所以我发现我的问题是在线程上，onCreate 线程开始。从 2.33 到 4.0.3 有什么区别吗？

package my.LigTv.Browser;

import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Intent;
import android.os.Bundle;
import android.view.MotionEvent;
import android.webkit.WebView;
import android.app.AlertDialog;
public class LigTVBrowserActivity extends Activity {
/** Called when the activity is first created. */


WebView mWebView;
AlertDialog alertDialog;
protected boolean _active = true;
protected int _splashTime = 3000; // time to display the splash screen in ms
int progress = 0;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);



    final Activity activity = this;

    final ProgressDialog progressDialog = new ProgressDialog(activity);
    progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
    progressDialog.setMessage("Please wait for the applet to load");

    progressDialog.show();
    progressDialog.setProgress(0);
    activity.setProgress(progress * 1000);

    progressDialog.incrementProgressBy(progress);

    if(progress == 100 && progressDialog.isShowing())
        progressDialog.dismiss(); 



    Thread splashTread = new Thread() {
        @Override
        public void run() {                 
            try {
                int waited = 0;
                while(_active && (waited < _splashTime)) {
                    sleep(100);

                    if(_active) {
                        waited += 100;                                                    
                        }
                }
            } catch(InterruptedException e) {
                // do nothing
            } finally {
                finish();
                startActivity(new Intent("my.LigTv.Browser.Starter"));
                stop();
            }
        }
    };
    splashTread.start();
}    

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        _active = false;
    }
    return true;
}

 }

尝试在开始新 Activity 后调用 finish()。另外，为什么要在线程上调用 stop() ？一旦开始新 Activity ，它将停止。这是我已经写过的例子，随便改:

            Runnable r1 = new Runnable(){
                public void run(){
                    new Handler().postDelayed(new Runnable(){
                        @Override
                        public void run(){
                            startActivity(new Intent(Splash.this,Main.class));
                            overridePendingTransition(R.anim.fade_out, R.anim.fade_in);
                            finish();

                        }
                    }, waitTime);
                }
            };
            runOnUiThread(r1);
