Hello,Bitcoin address transfer problem starting with 3 about bitcoinj

[HelpDesk-Ai]

Hello,If you use a Bitcoin address starting with 3 and transfer to an address starting with 1, how should you sign and broadcast? No need for multi-signature functionality.

How can I be of help

Use the Bitcoin address 3MtvkwxXtjK99GTvRKCMrfcPfb1CKd4FR5 to transfer to 1EN8KQzVYaZXWx8cZtWjxJUCQgfanNRnuU, and finally get the signature 0200000001f8bd6b068efceba07871dd6618baca979bd791a19f44ab7e7afc17590ed0ba6301000000610047304402205ab2526d9b4cd8062ae0e33d8809adc423e7e099f89c8f8638120291a3e5592a02200340607fb2bc371d377ffde32076f771ac82dc18b8d6a2f3850162fb2b304bbd0117a914dda33200ed8fd8ae42b3b415b82450f11a1061f587ffffffff02e8030000000000001976a91492987a8ca45b556f3e7f99b5cf4060accede7b3088acb9ff06000000000017a914dda33200ed8fd8ae42b3b415b82450f11a1061f58700000000

Use this signature to broadcast and report an error {"result":null,"error":{"code":-26,"message":"mandatory-script-verify-flag-failed (Script evaluated without error but finished with a false /empty top stack element)"},"id":null}
