Question

尝试在设备连接到互联网时打开网页。但是，我使用的服务正在崩溃应用程序。以下是Service类的源代码：

public class Opener extends Service {


final byte flag=0;
byte logger=0;

@Override
public void onCreate() {
    super.onCreate();
}

@Override
public void onDestroy() {
    super.onDestroy();
}

@Override
public void onStart(Intent intent, int startId) {
    // TODO Auto-generated method stub
    super.onStart(intent, startId);

    while(flag==0){

        ConnectivityManager cm = 
(ConnectivityManager)this.getSystemService(Context.CONNECTIVITY_SERVICE);

        NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
        boolean isConnected = activeNetwork != null && 
activeNetwork.isConnectedOrConnecting();

        if(isConnected)
        {
            if(logger==10)
            {
                this.stopSelf();
            }
            ++logger;

            Intent blower = new Intent();
            blower.setAction(Intent.ACTION_VIEW);
            blower.addCategory(Intent.CATEGORY_BROWSABLE);

blower.setData(Uri.parse("http://www.developer.android.com"));
            startActivity(blower);
        }
        else{
            ;
        }

        }

}





@Override
public IBinder onBind(Intent arg0) {
    return null;
}
}

这也是Logcat：

从一个类似的问题，找到使用FLAG_ACTIVITY_NEW_TASK的答案然而在我的情况下不起作用。任何帮助将不胜感激。

Answer 1

您已将自己的意图命名为blower，但是您将intent传递给startActivity。它应该是

startActivity(blower);

从服务崩溃应用程序启动网页
