[Android] Remove duplicate receiver in manifest and remove class definition

[YorkShen]

Remove duplicate receiver in manifest and remove class definition

• globalEvent demo, work as before.
• globalEvent Documentation
• As there is no intent-filter for the receiver in the manifest, the receiver in the manifest is useless. Actually, the receiver is registered in code with an intent.
