Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

an embodiment of the present invention provides a method for starting an application, which can be applied to devices such as a mobile phone, a tablet computer, and a PC, and the embodiment is described by taking an application to an android mobile phone as an example, as shown in fig. 1, the method includes the following steps:
s1, a task manager is generated according to the codes of the application program, and the application program is started.
S2, carrying out logic judgment according to the codes of the application program, and judging whether each third-party framework needs to be initialized; if yes, adding the initialization task of the third-party framework into a task set created according to the application program code, and if not, distributing the loading task of the third-party framework into the sub-thread for execution; tasks executed in the child thread do not affect the main thread. This screens out third party frameworks that need to be initialized.
And S3, dividing the initialization tasks in the task set into a first type of initialization task and a second type of initialization task according to the execution logic sequence of the initialization tasks, adding the first type of initialization task to the task manager, and adding 1 to the count of the task counter.
The first type of initialization task comprises the following steps: when an application program is started, an initialization task which needs to be executed preferentially is needed; the second type of initialization tasks includes: and the initialization task is executed after the first type task initialization task is executed. The first type of initialization task is executed in the main thread, and the second type of initialization task is executed in the sub-thread. This allows the initialization task of the third-party framework with the higher priority to be preferentially executed.
S4, sorting the first type of initialization tasks in the task manager according to the executed logic sequence, in this embodiment, sorting is performed by using a directed acyclic graph topology sorting method. For example, A, B, C, D four tasks, the logical order of execution is that A needs to be executed after B and C needs to be executed after D, then A, B, C, D four tasks may be ordered as (B, A), (D, C), or (D, C), (B, A).
And S5, adding synchronous locks to the main thread according to the number of the first type of initialization tasks in the task manager, wherein the number of the synchronous locks is equal to that of the first type of initialization tasks in the task manager, and the synchronous locks can ensure that the processor processes the tasks in the main thread preferentially. When the main thread executes tasks, the tasks are sequentially executed in the order of step S4.
And S6, starting distributing tasks, traversing all the first-class initialization tasks in the task manager, and judging whether the first-class initialization tasks need to be executed in the main thread. If so, after the main thread executes the task, unlocking the synchronous lock, and simultaneously subtracting 1 from the count of the task counter; if not, the method is distributed to the sub-thread for execution, and the main thread is not influenced. Therefore, the first type of initialization tasks are subdivided again, the first type of initialization tasks with higher priority are put into the main thread to be executed, and the initialization logic of a third-party framework is further optimized.
S7, judging whether the count of the task counter is 0, if yes, indicating that all third-party frameworks needing initialization are initialized, and starting the application program; if not, steps S5 and S6 continue until the task counter count is 0.
In this embodiment, a third-party framework to be initialized is first screened out, then the initialization task of the third-party framework is divided into a first-class initialization task and a second-class initialization task, the first-class initialization task is executed by calling the main thread, and the second-class initialization task is executed by the sub-thread, so that the utilization efficiency of the main thread of the processor can be improved, the initialization task of the third-party framework with a high priority is executed preferentially, unnecessary waste of processor resources is reduced, the execution logic of the initialization of the third-party framework is optimized, and the starting efficiency of the application program is improved.
