Research direction
Start at App.onCreate and follow the reported path through PatchManager.loadPatch, AndFixManager.fix, and SecurityChecker.verifyApk/check in SecurityChecker.java. Reproduce the failure with /data/data/amoy.com.test1/files/apatch/first.apatch and inspect the signature-verification inputs. Done means the cause of the wrong signature length is identified and the patch-loading flow is verified without this exception.
