Android - APP crashes when I call startActivity() with an impact intent

<activity
  android:name=".Fisrt"
  android:label="@string/title_activity_first" >
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />

    <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>
<activity
  android:name=".Second"
  android:label="@string/title_activity_second" >
  <intent-filter>
    <action android:name="com.example.MusicTest.First"/>
    <category android:name="ANDROID.INTENT.CATEGORY.DEFAULT"/>
  </intent-filter>
</activity>

And in my First.java, the code is below.

public final static String MY_ACTION = "com.example.MusicTest.First";

public void change(View view) {
    Intent intent = new Intent(First.MY_ACTION);
    startActivity(intent);
}

The problem is everytime I call change(), the APP would crash. Any Input will be helpful. Thanks.

/supplement/ The log is below:

There is spelling mistake in manifest

<activity
  android:name=".Fisrt"

should be 

android:name=".First"

because your MY_ACTION string is First

public final static String MY_ACTION = "com.example.MusicTest.First";

Please try the below code for setting the action.

Intent intent = new Intent();
intent.setAction(First.MY_ACTION);
startActivity(intent);

Second activity will be launched after that.

And of course, you can also add

intent.addCategory("android.intent.category.DEFAULT");

for setting category which you set for Second activity in AndroidManifest.

Change your manifest file to:

<activity
  android:name=".Fisrt"
  android:label="@string/title_activity_first" >
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />

    <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>
<activity
  android:name=".Second"
  android:label="@string/title_activity_second" >
</activity>

To start Second Activity, try the follow code:

Intent intent = new Intent(First.this, Second.class);
startActivity(intent);
