IntentSanitizer

Added in 1.9.0

class IntentSanitizer

This class is used to make a sanitized copy of an Intent. This could be used when UnsafeIntentLaunchViolation is detected. This class is thread safe and the object created is safe to be reused. Typical usage of the class: 

Intent intent = new  IntentSanitizer.Builder()
     .allowComponent(“com.example.ActivityA”)
     .allowData(“com.example”)
     .allowType(“text/plain”)
     .build()
     .sanitizeByThrowing(intent);
 At least one of the allowPackage, allowComponent must be called unless implicit intent is allowed. In which case, allowAnyComponent must be called and caution has to be taken to protect your private data.

Summary

Nested types
