Acquisition file size method, and record the size of Android application program file.
S106 judges whether the storage size of free time is less than the size of Android application program file, if so, enters
S104；If it is not, entering S107.
If the storage size of free time, cannot be by Android application program less than the size of Android application program file
File copy can only point out SD card partitioned storage space full in SD card subregion, need to delete the partial data in SD card subregion
Operated again.
S107 judges whether the size of Android application program file is 0, if so, into S108；If it is not, entering S109.
If the All Files size under the file of Android application program is more than 0, false (vacation), table are directly returned
There are data in the file for showing Android application program.
If being 0 without file or All Files size under the file of Android application program, true (true) can be returned,
Represent that Android application program file does not have data.
S108 shows Android application program file in mobile client for sky, end.
If Android application program file is sky, then avoid the need for carrying out any extraction operation, in mobile client
Directly eject information and inform developer, inside Android application program file, there is no any data, Android application program file
For empty information.
S109 is created for storing the catalogue of Android application program file in SD card subregion.
Creating in SD card subregion includes obtaining Android application program for the catalogue for storing Android application program file
Bag name, detects all catalogues in SD card subregion, deletes the bag name identical catalogue of title and Android application program, and in SD card
Create in subregion for storing the catalogue of Android application program file.Comprise the following steps that：
If whether Android application program file is not sky, then next can judge SD card subregion before stored mistake
Android application program file.
A) Android application program bag name is obtained, Android application program bag name is the unique identifier of Android application program, its
Real is exactly a string special character strings, and usual naming method is similar to the forms such as com.douyu.tv.air.Obtain ARIXTRA application journey
Sequence bag name is the function getPackageName by calling Android operation system to provide, and getPackageName functions are to obtain
The function of bag name, it becomes possible to obtain the bag name of the Android application program.
B) all catalogues of searching loop SD card subregion, obtain the directory name character string of all catalogues of SD card subregion, lead to
Whether cross equals methods identical with Android application program bag name to compare the directory name of all catalogues of SD card subregion.equals
Method is character string comparison function, and character string is identical to be returned very, differs return false.
C) if it find that there is the bag name identical catalogue of title and Android application program on SD card subregion, illustrate to grasp at this
An Android application program file was copied before making once, what the inside was deposited is the historical data of Android application program file,
We should carry out deletion action to historical data first, can delete the catalogue file by calling remove methods, delete
After completing, the corresponding catalogue of mkdir function creation bag names is called manually.Remove methods are for the function that deltrees
Method, mkdir functions are the functions for createing directory.
If d) there is no the bag name identical catalogue of title and Android application program on SD card subregion, mkdir is directly invoked
Function is creating the corresponding catalogue of Android application program bag name.
The present invention can obtaining Android application program file and before being stored in SD card subregion, SD card subregion it is full and
In the case that Android application program file is for sky, points out developer to delete the partial data in SD card subregion, and ARIXTRA should
It is not space-time with program file, then enters to be about to the operation that Android application program file is stored in SD card subregion, it is to avoid loses time, enter
One step improves the development efficiency of Android application program.
S200 from the data subregions of mobile client obtains Android application program file and is stored in the SD of mobile client
Card subregion.

Any one file, in order to be hereinafter described conveniently, this document is named as file, shown in Figure 3, and concrete operations are as follows：
S201 reads the data for being less than predefined size from file f ile as current data.
Current data is stored in buffer zone by S202, and the ARIXTRA application journey created under SD card subregion is write from buffer zone
In the corresponding catalogue of sequence bag name.
Whether S203 includes the end mark of file f ile in judging current data, if so, terminate；If it is not, entering S204.
If current data includes the end mark of file f ile, then this when is all by what is read in buffer zone
All in write file files, so the reading of this file f ile and ablation process are just completed data.
S204 data less than predefined size after current data are read from file f ile as renewal after work as
Front data, into S202.
If the end mark in current data not including file f ile, the reading and storage of the data of supporting paper file do not have
There is end, continue repeat step S202 and S203, circulation execution is gone down.
The benefit of the buffer zone of predefined size can be to be effectively reduced frequently I/O operation (read-write operation of file),
Expire when buffer zone can just carry out I/O operation, if no buffer zone, then be written to SD card point after reading data at once
Area, causes I/O operation very frequent, as I/O operation is, than relatively time-consuming operation, to ultimately result in acquisition Android application program file
And be stored in SD card subregion process it is less efficient.
The present invention creates buffer zone in the internal memory of mobile client, by buffer zone by application file
Data are stored in SD card subregion, it is to avoid frequently I/O operation, improve reading and the storage efficiency of data.
