Android allows applications to communicate between processes through intents, which not only provides convenience for data sharing but also brings many hidden dangers. If developers do not properly dispose of intents transmitted between processes, it may lead to security vulnerabilities such as information leakage, permission escalation, and arbitrary code execution.

This article mainly introduces the security issues that may arise from the transfer of intent between activities, helping developers and security testers to correctly understand such issues. The transfer of intent between activities is mainly achieved through startActivityForeresult and setResult.
