android how with intent to jump to the File Manager

Android File Manager intent

I want to achieve is to click a button, and then jump to the File Manager main interface, browse files.
Intent intent = new Intent ();
intent.setAction ("android.intent.action.MAIN") ;/ / this place did not achieve the desired effect for a lot of
intent.addCategory ("android.intent.category.DEFAULT");
startActivity (intent);

Which in the end is inside the parameters of the intent-filter action name? ?
Android.intent.action.SEARCH can jump with the file manager search interface
With com.mediatek.filemanager.DOWNLOAD_LOCATION can jump to download the file manager interface
You can skip to increase with com.mediatek.filemanager.ADD_FILE file (paste) interface
So have tried ......
However, the file manager can not be the main interface!

So it

 Intent mIntent = new Intent (); 
ComponentName comp = new ComponentName ("com.mediatek.filemanager", "com.mediatek.filemanager.FileManagerOperationActivity"); 
mIntent.setComponent (comp); 
mIntent.setAction ("android.intent.action.VIEW"); 
startActivity (mIntent); 

May need to set mIntent.flag to new_task, you try it
