我目前正在編寫一個應用程序,它使用NFC在兩個設備之間發送文本。我有兩臺Nexus S手機,一臺運行冰淇淋三明治,一臺運行薑餅2.3.6。Android NFC Gingerbread到ICS NDEF推不工作
程序推NDEF消息,使用例如谷歌代碼正確形成,到前臺等待被拾起,那個小的代碼片段是在這裏:
/**
* Push an NDEF to the foreground with the given text.
* @param message The text to be put in the message that will be pushed.
*
*/
public void pushNDEFwithText(String text)
{
NdefRecord ndefRec = createTextRecord(text, Locale.ENGLISH, true);
NdefMessage message = new NdefMessage(new NdefRecord[]{ ndefRec });
nfcAdapter.enableForegroundNdefPush(this, message);
Log.i("NDEF", "Pushed an NDEF message containing the text: "+text);
}
程序正常工作時,我有Gingerbread Nexus將標籤推到前臺,ICS很好地採用它,並且我正在使用NFCTagInfo來讀取它。
問題:當我有ICS Nexus將標籤推到前面時,薑餅人似乎沒有把它拿起來。由於ICS使用SNEP和Gingerbread使用NPP,我認爲我遇到了一些問題,有沒有辦法迫使ICS使用NPP?或者如果有人認爲這不是問題,他們會是什麼?
注意:理想情況下,我只是喜歡獨家使用ICS,但Google因爲缺陷而停止播出,並且因爲ICS更新打破了Nexus上的USB調試,所以我不得不通過互聯網安裝測試應用程序,並通過查看設備上的日誌,並不理想,所以我只是開發薑餅。這也是爲什麼我不能張貼從ICS的日誌,但在這裏從當NDEF在ICS前景的薑餅之一,薑餅正在接收(它不工作):

我不認爲我有梁轉身,我已經得到「解決」它另一個ICS電話。 – Peanut 2012-03-05 18:47:12
