I am trying to start activity at start up of phone but whole program is not running there is a no error in program , see my coding bellow(or here http://pastebin.com/BKaE4AaU):

autostart.java 的

import android.content.BroadcastReceiver;  
import android.content.Context;  
import android.content.Intent;  
import android.content.SharedPreferences;  
import android.preference.PreferenceManager;  
import android.util.Log;


public class autostart extends BroadcastReceiver 
{
    public void onReceive(Context arg0, Intent arg1) 
    {
        Intent intent = new Intent(arg0,service.class);
        arg0.startService(intent);
        Log.i("Autostart", "started");
    }
}

service.java 的

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;

public class service extends Service
{
    private static final String TAG = "MyService";
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
    public void onDestroy() {
        Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
        Log.d(TAG, "onDestroy");
    }

    @Override
    public void onStart(Intent intent, int startid)
    {
        Intent intents = new Intent(getBaseContext(),hello.class);
        intents.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intents);
        Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
        Log.d(TAG, "onStart");
    }
}

hello.java 的

import android.app.Activity;
import android.os.Bundle;
import android.widget.Toast;

public class hello extends Activity 
{   
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Toast.makeText(getBaseContext(), "Hello........", Toast.LENGTH_LONG).show();
    }
}

manifest.java是如下的

         

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <receiver  android:name=".autostart"
              android:label="@string/app_name">
        <intent-filter>
              <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>

             

推荐答案

您的XML应该存储在一个名为AndroidManifest.xml中，文件中没有manifest.java。

Your XML should be stored in a file named AndroidManifest.xml, not manifest.java.

另外一个原因，你的code没有运行，可能是您的应用程序安装在外部存储（SD卡）。 BOOT_COMPLETE发送到应用程序的外部存储设备安装前。因此，如果应用程序被安装到外部存储它不会收到BOOT_COMPLETE广播消息。

Another reason your code is not being run, might be that your App is installed on external storage (sdcard). BOOT_COMPLETE is sent to applications before external storage is mounted. So if application is installed to external storage it won't receive BOOT_COMPLETE broadcast message.

如果这不是问题，已经有一个的如何获得启动完成接收工作在Android 很好的说明。

If that isn't the problem, there is already a very good description of how to get boot completed receivers working on Android.
