Activity wont start with "startActivity();"

Here's my code for DroidArmoryActivity

package com.maxgenero.droidarmory;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;

public class DroidArmoryActivity extends Activi开发者_开发问答ty implements View.OnClickListener {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    switch(v.getId()) {

    case R.id.ibM4A1:
        Intent intentM4A1 = new Intent("com.maxgenero.droidarmory.M4A1GUN");
        startActivity(intentM4A1);
        break;

        }
    }
}

It's not starting the java file (Activity) at all, no errors. Btw, the case is looking for an imageButton. Here's my Manifest, at least the part you need:

<activity android:name=".M4a1"
                  android:label="@string/app_name"
                  android:screenOrientation="landscape">
              <intent-filter>
                 <action android:name="com.maxgenero.droidarmory.M4A1" />
                 <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

And the file name for the java file is M4a1.java. If you need more info let me know, thanks.

I dont see where you define a listener on your Button or your View that will be clicked to launch the second Activity ??

yourView.setOnClickListener(this); 

the second thing is that you should add declare your activity on your manifest file on the tag like this :

<activity android:name="your.package.name.NameOfYourAcitivity" />

the last thing is : try to instantiate the intent like this :

this.startActivity(new Intent(this, SecondActivity.class));

Instead of...

case R.id.ibM4A1:
    Intent intentM4A1 = new Intent("com.maxgenero.droidarmory.M4A1GUN");
    startActivity(intentM4A1);

Try

Intent intentM4A1 = new Intent(this, ACTIVITY_NAME.class);
startActivity(intentM4A1);

Also dont forget to call your setOnclickListener().
