活动有时会从 NfcService 中删除。如何检测从 NfcService 中删除我的活动？以及如何将我的活动重新注册到 NfcService？

▼我的设置如下。

NfcAdapter m_NFC;

@Override
protected void onPause() {
    if (isFinishing()) {
        if (m_NFC != null) {
            m_NFC.disableForegroundDispatch(this);
        }
    }
    super.onPause();
    return;
}

@Override
protected void onResume() {
    super.onResume();
    m_NFC.enableForegroundDispatch(this,PendingIntent.getActivity(this, 0, new Intent(this, getClass()), 0),null,null);
    return;
}

▼启动模式

android:launchMode="singleTask" or "singleTop"

▼日志如下...
