a third processing module, configured to, when the first function is detected, scan a shared library including the first function, so as to detect a second function paired with the first function;
the fourth processing module is used for determining that no thread leakage exists in the thread running the application program package when the second function is detected;
wherein the scanning the shared libraries called by any one of the plurality of shared libraries except for any one of the shared libraries comprises:
traversing the shared libraries except any shared library through a plug-in program, and inquiring external symbols called by the shared libraries except any shared library;
wherein the first function comprises a thread-created function and the second function comprises at least one of:
a thread separation state function and a thread recycle function.
6. The apparatus of claim 5, comprising:
a fourth processing module, configured to determine that a thread leakage exists in a thread running the application package and determine information of any shared library when the second function is not detected; and repairing the thread leakage according to the information of any shared library.
7. An electronic device, comprising: a processor, a memory;
the memory for storing a computer program;
the processor, configured to execute the method for detecting a thread according to any one of claims 1 to 4 by calling the computer program.
8. A computer-readable medium, in which a computer program is stored which, when being executed by a processor, is adapted to carry out the method of detecting a thread according to any one of claims 1 to 4.
