By adopting the technical scheme, the cold start of the application program is executed in an asynchronous loading mode by utilizing the characteristic of multi-core of the mobile terminal processor, and the resource component is loaded in advance in the starting process, so that the aims of accelerating the loading speed and the starting speed of the application program are fulfilled.)

1. A layout file preloading method under an Android platform is characterized by comprising the following steps:

responding to the click of the user, and cold starting the application program;

creating a main process of the application program, wherein the main process comprises a first thread;

creating a second thread in the main process according to the number of resource assemblies to be analyzed, wherein the second thread analyzes the resource assemblies;

and the first thread loads the resource assembly analyzed and completed by the second thread to complete the cold start of the application program.

2. The method for preloading a layout file according to claim 1, wherein the creating a host process of the application program, the host process including a first thread, further comprises:

the first thread creates and initializes Application;

the first thread calls the onCreate function to create and initialize MainActivity.

3. The method for preloading a layout file according to any one of claims 1 to 2, wherein the creating of the second threads in the main process according to the number of resource components to be resolved is specifically to create the same number of second threads according to the number of resource components;

optionally, the second thread parsing the resource component further comprises,

setting the PRIORITY of the second THREAD as a visible THREAD read _ PRIORITY _ DISPLAY;

setting a class loader ClassLoader of the second thread, which is used for loading a corresponding loading class in the resource component;

creating the resource assembly analyzer, analyzing the resource assembly and obtaining the corresponding View;

and putting the corresponding View obtained by analyzing the resource component into a memory.

4. The method of any of claims 1 to 3, wherein the loading of the resource component parsed by the second thread by the first thread further comprises the onCreat function reading the View from memory;

optionally, the onCreat function reading the View from memory further comprises,

the onCreat function calls a setContentView function to construct a DecorView;

and reading the second thread View from the memory, and adding the View to the DecorView.

5. The layout file preloading method of any one of claims 1 to 4, wherein the completing the application cold start further comprises:

and adding the DecorView added with the View into the Window to finish the cold start of the application program.

6. The layout file preloading device under the Android platform is characterized by comprising:

the response module is used for responding to the click of the user and cold starting the application program;

the first thread creating module is used for creating a main process of the application program, and the main process comprises a first thread;

the second thread creating module is used for creating a second thread in the main process according to the number of the resource assemblies to be analyzed, and the second thread analyzes the resource assemblies;

and the first thread loads the resource assembly analyzed and completed by the second thread to complete the cold start of the application program.

7. The layout file preloading device according to claim 6, wherein creating a main process of the Application program, the main process including a first thread further comprises the first thread creating and initializing Application;

the first thread calls the onCreate function to create and initialize MainActivity.

8. The layout file preloading device according to any one of claims 6 or 7, wherein the creating of the second threads according to the number of resource components to be resolved is specifically to create the same number of second threads according to the number of resource components;

optionally, the second thread parsing the resource component further comprises,

setting the PRIORITY of the second THREAD as a visible THREAD read _ PRIORITY _ DISPLAY;

setting a class loader ClassLoader of the second thread, which is used for loading a corresponding loading class in the resource component;

creating the resource assembly analyzer, analyzing the resource assembly and obtaining the corresponding View;

putting the corresponding View obtained by analyzing the resource component into a memory;
