public ShadowCryptoObject()

Method Details

getOpId

@Implementation
@HiddenApi
protected final long getOpId()

The shadow method of CryptoObject#getOpId.

The CryptoObject#getOpId implementation in AOSP calls javax.crypto.CipherSpi#getCurrentSpi to retrieve javax.crypto.Cipher, but this API is added by Android JDK implementation, and not supported by OpenJDK. To avoid this issue, we shadow CryptoObject#getOpId to intercept call-chain early. Related issue: java.lang.NoSuchMethodError: 'javax.crypto.CipherSpi javax.crypto.Cipher.getCurrentSpi().

Returns:

0L as default value.
