Method and apparatus for collecting information, and method and apparatus for releasing memory

An apparatus for collecting information, comprising:

• at least one processor;
• and
• a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions instruct the at least one processor to perform the following operations:
• when a quantity of times of invoking a target method in a running lifecycle of a target program increases, obtaining, based on a method identifier of the target method, the quantity of times of invoking the target method, wherein the target program is any running program, and the target method is any one of at least one method invoked by the target program;
• recording method information of the target method based on a first threshold, a second threshold, and the quantity of times of invoking the target method, wherein the first threshold and the second threshold are positive integers, and the second threshold is greater than 0 and less than the first threshold;
• and
• setting a method status of the target method based on the first threshold, the second threshold, and the quantity of times of invoking the target method, wherein the method status is used to indicate a status of the method invoked by the target program and corresponding to the method status, the method status is a first state or a second state, the first state corresponds to the first threshold, and the second state corresponds to the second threshold.
