为什么我收到错误暂停 ActivityNotFoundException？

Question

package com.basic.android;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

public class androidbasics extends Activity {
    /** Called when the activity is first created. */

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

        Thread logoTimer = new Thread(){
            public void run(){
                try{
                    int logoTimer=0;
                    while(logoTimer<5000){
                    sleep(500);
                    logoTimer = logoTimer +100;
                    }

                startActivity(new Intent("com.basic.android.MENU"));    
            }catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }finally{
                finish();
                        }
            }        
        };
        logoTimer.start();
    }


    @Override
    protected void onDestroy() {

Answer 1

change..(see DEFALT change to DEFAULT in category)

Answer 2

The issue was in mismatch in defining activity name. In manifest you have defined the activity name is menu not MENU

<activity android:name=".menu"
                  android:label="@string/app_name">

But in code startActivity(new Intent("com.basic.android.MENU")); you want to start an activity MENU whcich is not defined because in manifest menu is defined but MENU is not defined

The activity name is case sensitive

Answer 3

The issue was in mismatch in defining activity name. In manifest you have defined the activity name is menu not MENU

<activity android:name=".menu"
                  android:label="@string/app_name">

Android Studio is case sensitive, so this should work.

Answer 4

Before calling startActivity(new Intent("com.basic.android.MENU")) cancel your logoTimer

like

logoTimer.cancel();
startActivity(new Intent("com.basic.android.MENU"))

//

public void toCallActivity() {
    TimerTask startNewActivity;
final Handler handler = new Handler();
Timer timer = new Timer();


        startNewActivity = new TimerTask() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                handler.post(new Runnable() {
                    public void run() {

                        try {
                                             timer.cancel();
startActivity(new Intent("com.basic.android.MENU"));

                        } catch (Exception e) {
                            // TODO Auto-generated catch block


                        }

                    }
                });

            }

        };

        timer.schedule(startNewActity, 0,5000);

    }
