My application not get started when device started?

Question

I've written following class to start my application activity Home.class but on device start up it shows error forced close.

public class MyBootRecvr extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Intent i = new Intent(context, Home.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        i.addFlags(Intent.FLAG_FROM_BACKGROUND);
        context.startActivity(i);
        Toast.makeText(context, "Where is my KeyBoard", Toast.LENGTH_LONG)
                .show();
    }
}

Permissions and receiver tags in application.

<receiver
     android:name=".Home"
     android:enabled="true"
     android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
     <intent-filter>
         <action android:name="android.intent.action.BOOT_COMPLETED" />
         <category android:name="android.intent.category.DEFAULT" />
      </intent-filter>
 </receiver>

when phone starts there is no debugging and no logcat message — , Jun 15 '12 at 09:05
as imran said please post your logcat so that we can get idea where the error is — Dheeresh Singh, Jun 15 '12 at 09:08
I think as you get forced close so it should be linked with Home.java — Dheeresh Singh, Jun 15 '12 at 09:09
Shouldn't the android:name in the receiver actually refer to .MyBootRecvr? — Xono, Jun 15 '12 at 09:44

If this is the only code in your application, it will never run. Android applications must have at least one subclass of Activity as a starting point for when you run the app. The Activity could should at a minimum look something like this:

class MyActivity extends Activity {
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.my_layout); /* my_layout should be an XML layout in res/layout */
    }
}

Make sure the following code in is your AndroidManifest.xml file

<activity android:name="MyActivity">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

If you create a new Android project in Eclipse, it will do this setting up for you. There are a lot of tutorials on both setting up a basic application in Android, and using Eclipse to do it for you.

my app do have an activity thats what i am starting from intent – Jun 15 '12 at 09:06
Intent i = new Intent(context, Home.class); – Jun 15 '12 at 09:06
first be sure what you're posting – Jun 15 '12 at 09:11
As far as I'm aware, the application must have an Activity to be launched when you open it. That activity should not be launched via an Intent, rather the intent filters you specify for it (as shown in my answer's AndroidManifest) caused it to be launched automatically. I'm not sure why you're trying to use an intent to manually launch it. – Xono Jun 15 '12 at 09:29
intent is used there when device start to start activity in background not i front – Jun 15 '12 at 11:11
