I've been learning alot from this wonderful website, and I'd like to ask my first question on Android; For security reasons, would there be any way I could prevent any other apps from starting my own app? Thank you very much

When an app is calling another app, it usually uses startActivity or startActivityForResult.

If the call is made with startActivity, there is nothing than can get you the sender information (http://stackoverflow.com/questions/4789155/how-to-find-intent-source-in-android) : 

private String mAction;
private Uri mData;
private String mType;
private String mPackage;
private ComponentName mComponent;
private int mFlags;
private HashSet<String> mCategories;
private Bundle mExtras;

If it uses, startActivityForResult, it creates an intent that you can get through getIntent() and eventually retrieves the original intent and do a kill if you're in this case.

So in short, you're not 100% sure it will work.
