Abstract
The invention discloses a kind of prioritization scheme of android applications cold start-up, including following key step：Step one：A drawable file of entitled shape_launch.xml is created in windowBackground property files folder in theme；Step 2：Topic style in modification windowBackground property file folders in styles.xml files；Step 3：Amended topic style is set to the Activity for starting.Several seconds even more long white screens of the appearance that experience is needed in first time cold start-up or blank screen time is applied to enter the problem of main interface present invention optimizes android, after user is clicked on app icons, customized pattern or logo figures can quickly be loaded out, app applications are caused to start sensation quickly in use, it is possible to strengthen the propagation of brand.
Description
Technical field
The present invention relates to Android application Starting mode, specifically a kind of prioritization scheme of android applications cold start-up.
Background technology
Cold start-up is the important Starting mode of Android application, in Android system, system be each operation application extremely
A process (multi-process application application multiple process) is distributed less.From process angle, cold start-up is exactly to apply preceding in startup,
There is no the people of the application and progress information in system (including Activity, Service etc.).Applied after such as device power-up
One-shot, system kills application process (such as：Installed System Memory be critical initiation kill and user actively produce kill) after
It is again started up.Under so naturally this mode, the startup time of application is more long,
During using cold start-up occurring, system needs to complete following three tasks：
1. start to load and start application；
2. after application starts, a starting-window for blank is shown；
3. application process information is created；
After system creation application process information, application will complete following operation：
1) object (work in such as Application) in initialization application；
2) main thread (UI threads) is started；
3) first Activity is created；
4) loading content view (Inflating)；
5) position typesetting (Layingout) of the view on screen is calculated；
6) drawing view (draw).
Only when application completes first time drawing view, the blank background of system current presentation can just disappear, just can quilt
The content view of Activity is replaced.Namely this when, user could start interaction with our application.
, it is necessary to complete two establishment work after system creation application process information, respectively in the first step
Establishment Activity in Application and the 3rd step.Above-mentioned two establishment work is before drawing view.So,
In using customized Application classes and first Activity class, because the presence for creating work twice causes cold opening
The time of dynamic consumption is more long.
How to reduce the long problem of time loss in Cold Start, at present using more prioritization scheme be exactly
In Application and first Activity, the workload of creation method is reduced, so as to shorten the time of cold start-up.It is a kind of
Mode is some the third party SDK being embedded in the application, and some initial works are done in Application, and developer one
As take the form of lazy loading to remove this partial code, and it is real need to use third party SDK when initialized again, so
Can cause user that white screen or blank screen are can be appreciated that in cold start-up.It is exactly to be set by theme that another processing mode is more simple and crude
Put, white screen background during startup is not shown.Under cold start-up mode, user clicks on desktop icons, does not have any reaction, when crossing one section
Between using just opening.Merely just by white screen background transparent or stash in fact.User can so be caused in point
After hitting application, to wait for a period of time to start, so as to cause using experience extreme difference in use.
The content of the invention
It is an object of the invention to provide a kind of prioritization scheme of android applications cold start-up, to solve above-mentioned background skill
The problem proposed in art.
To achieve the above object, the present invention provides following technical scheme：
A kind of prioritization scheme of android applications cold start-up, mainly includes the following steps that：
Step one：An entitled shape_ is created in windowBackground property files folder in theme
The drawable files of launch.xml；
Step 2：Topic style in modification windowBackground property file folders in styles.xml files；
Step 3：Amended topic style is set to the Activity for starting.
Compared with prior art, the beneficial effects of the invention are as follows：
Applied present invention optimizes android needed in first time cold start-up several seconds of appearance of experience it is even more long
White screen or blank screen time could enter the problem of main interface, after user is clicked on app icons, can quickly load out customized sample
Formula or logo scheme, and cause app applications to start sensation quickly in use, it is possible to strengthen the propagation of brand.
Specific embodiment
Technical scheme is described in more detail with reference to specific embodiment.
A kind of prioritization scheme of android applications cold start-up, comprises the following steps：
Step one：An entitled shape_ is created in windowBackground property files folder in theme
The drawable files of launch.xml；Its specific code is as follows：
Step 2：Topic style in modification windowBackground property file folders in styles.xml files；Its
Specific code is as follows：
<Style name=" LaunchStyle " parent=" AppTheme ">
<Item name=" android:windowBackground">@drawable/shape_launch</item>
</style>
Step 3：Amended topic style is set to the Activity for starting；Its specific code is as follows：
Better embodiment of the invention is explained in detail above, but the present invention is not limited to above-mentioned embodiment party
Formula, in the ken that one skilled in the relevant art possesses, can also be on the premise of present inventive concept not be departed from
Various changes can be made.
