Android 库：是否可以将 Intent 传递到我的库中以检索 ParcelableExtra 的

Question

I want to use the ParcelableExtra function of an Intent to retrieve an android.nfc.Tag Object

nfcTag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);

In the newIntent function this code works. But now I want to write an Android Library which uses the same android.nfc.Tag Object.

Is it possible and state of the art to pass an Intent into an Android Library?

Answer 1

It is not "state of the art" to pass an Intent object to a library, while this might be technically possible because because an Intent is just an instance of a standard type Java class that can be passed between methods whether inside the App code or in a library.

The reason why you should not uses the Intent Object is because the newer and better NFC API of enableReaderMode does not use Intent s it just gets passed the Tag Java Object directly when a Tag is discovered.
Thus it is better for your library to accept a Tag object as input as then it could be used with the older and newer (better) NFC API's
