Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method for storing the playing information based on the android system can be applied to terminals. The terminal may be, but is not limited to, various personal computers, notebook computers, mobile phones, tablet computers, vehicle-mounted computers, and portable wearable devices. The terminal of the invention adopts a multi-core processor. The processor of the terminal may be at least one of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a Video Processing Unit (VPU), and the like.
The invention provides a method for storing playing information based on an android system, which comprises the following steps of:
and S100, starting a preset monitoring program to monitor the application installation process of the intelligent terminal and judging whether the intelligent terminal is provided with a third-party application.
Step S200, when the fact that a third-party application is installed on the intelligent terminal is monitored, whether the third-party application is a video playing application is judged, and when the third-party application is the video playing application, the video playing application is matched with an Android system with a source code of a native player modified in advance.
Step S300, when the video playing application is monitored to play the video and the playing is finished, playing information is obtained through a player callback interface, and the playing information is stored in a historical database.
In specific implementation, since the video playing application pre-installed in the system (i.e., the video playing application carried by the intelligent terminal when the system leaves the factory) is pre-adapted to the history database in the intelligent terminal system, the video watched by the user last time is stored in the history database of the system. However, after the user uses the intelligent terminal, the third-party video playing application installed by the user himself does not store the video watched by the user last time in the history collection application because the third-party video playing application is not adapted to the history database in the intelligent system in advance, so that the user does not leave the history watching record in the history database after watching the video by using the third-party video playing application every time, the user cannot find the video watched before in the history database when watching the video next time, and inconvenience is brought to the user. In order to solve the above problem, this embodiment provides a method for storing playing information based on an android system, where a native player source code is modified in advance, and when it is monitored that a third-party video playing application is installed in an intelligent terminal, the third-party video playing application is adapted to be compatible with a historical database, so that when the playing of the third-party video playing application is finished, the playing information is stored in the historical database, so that a user can continue to watch the playing information.
Specifically, in this embodiment, a monitor is set in the Android system in advance, and is used to monitor whether the intelligent terminal installs the third-party application. Preferably, the Android platform-based application installation method can be divided into two types, one type is interface installation, and the other type is non-interface installation. The installation with the interface is actually used, a user can see the installation application interface popped up by the system, and the installation without the interface is realized by a developer through a command. The embodiment aims at installing a third-party application in the using process, namely, the method corresponds to a bounded surface installation mode. The interface installation mode is the Package Installer Activity interface in the Android native system, and the source code positions are as follows:
Packages/apps/PackageInstaller/src/com/android/packageinstaller/PackageInstallerActivity.java。
in the embodiment, a monitor is mainly set in an onCreate function in a source code position of an interface of the Android native system Package lnstar Activity to monitor whether a user installs a third-party application, and when the user starts the Android system, the monitor is automatically monitored so as to monitor whether the user installs the third-party application in time. Preferably, in this embodiment, the monitoring program may be automatically started at preset time intervals for monitoring, or the monitoring program may be set to be started for a long time. Preferably, in order to solve the problem that, in the prior art, when a user installs a third-party application on an intelligent platform, an Android system of an intelligent terminal cannot be adapted to the newly installed third-party application in advance, especially when the third-party application is a video playing application, since the newly installed video playing application is not adapted to the Android system of the intelligent terminal, a history watching record of a video watched by the user using the newly installed video playing application cannot be left in a history database, and the user cannot watch the video continuously next time. Therefore, in the embodiment, the native player source code of the Android system is modified in advance, and the modified content includes: the method comprises the steps of adding a monitoring playing interface in a native player of the Android system, adding a playing information member object in the native player of the Android system, modifying a playing video source function and modifying a playing ending scene in a message processing function of the native player of the Android system.
The specific modification steps are as follows:
1) a monitoring and playing interface is added in a source code of the native player of the Android system and used for monitoring whether a newly installed video playing application plays a video or not;
the pseudo code may be referred to as follows:
public interface OnPlayListener{
void onPlay (LinkedList<HashMap<String, String>>playInfo);
}
wherein the parameter playInfo is playing information;
2) adding a play information member object in a source code of an Android system native player
The pseudo code may be referred to as follows:
private LinkedList<HashMap<String, String>>mPlayInfo;
3) modifying the play video Source function, i.e. set Data Source (streaming path) function, it is known that when a certain video needs to be played, the play Data Source can be set by the Android native Media Player object set Data Source (Context, Uri) function. In this embodiment, the Android native player changes the playing video Source function set Data Source (Context, Uri) into set Data Source (Context, Uri, onplaylistenerplaylnfo), and stores the incoming On playlistener interface object in the playing information member object mplaylnfo in the above step 2), so as to store the playing Data conveniently;
4) modifying the end of Play scene
Modifying a playing ending scene in a message processing function in a source code of the Android system native player for inserting playing related information into a history database, wherein the pseudo code can refer to the following:
public void handle Message(Message msg) {
switch(msg.what) {
case MEDIA_PLAYBACK_COMPLETE:
if (mOn CompletionListener != null)
mOnCompletionListener.onCompletion(mMediaPlayer);
return;
}
}
wherein, MEDIA _ playlist _ COMPLETE is a CASE for processing the end of play, and is defined as follows:
private static final int MEDIA_PLAYBACK_COMPLETE = 2。
in addition, in this embodiment, a player play callback interface is further added to the native player of the Android system, and the play callback interface is used for acquiring play video information in subsequent steps and inserting the information into a system preset history collection application database.
Further, the problem to be solved in the present embodiment is that the video playing newly installed by the user should be adapted to the Android system, so that the video watched by the user using the newly installed video playing application can leave a history watching record in the history database. Therefore, in this embodiment, after the user monitors that the third-party application is installed in the intelligent terminal, it is necessary to determine whether the third-party application is a video playing application. Specifically, in the starting process of the Android system, an application management Service, Package Manager Service, is started, and this Service is responsible for scanning a specific directory in the system and finding out an application file therein. After the monitoring intelligent terminal installs the third-party application, the application program management service can find an application program file taking apk as suffix, analyze the application program file and acquire an interface name of the newly installed third-party application; decompiling the application program files by adopting an apktool tool, generating a smali file under a decompiling engineering directory, traversing and analyzing the smali code file carrying the application interface name in a smali folder according to the obtained application interface name, obtaining an interface of a newly installed third party application, and then judging whether the interface carries a playing interface. Since the application based on the Android system is used for playing a video by calling a native Player (Media Player), and there is a related call of a Player (Media Player) interface in a playing interface, if a playing interface of a newly installed third-party application is found, it is determined that the third-party application is a video playing application.
Among them, the smali pseudo code of the native Player (Media Player) is as follows:
invoke-virtual {v0, v1},
Landroid/widget/VideoView;->setOnErrorListener(Landroid/media/MediaPlayer$OnErrorListener;) V //
and if the smali code file is checked to contain Landoroid/media/MediaPlayer keywords, judging that the interface is the playing interface.
Further, after the third-party application is judged to be the video playing application, the related information of the video playing application is obtained, and the related information is stored in the playing information member object of the native player with the source code modified in advance. In this embodiment, after the playing interface of the installation application is obtained, an interface for calling the native player is obtained, a playing video source function of the video playing application is modified, and a playing video source is set. For example, the original video playing Source function setData Source (Context, Uri) is modified into set Data Source (Context, Uri, onplaylist), when the user uses the video playing application to play video, the function can be used to obtain the packet names of the video playing application and the playing interface, play the information of the movie, and store the information in the parameter playInfo of the onPlay function,
the pseudo code may be referred to as follows:
MediaPlayer.setDataSource(Context, Uri，new OnPlayListener () {
@Override
public void onPlay(LinkedList<HashMap<String, String>>playInfo){ }
}。
preferably, after a playing interface of the installation application is acquired, a playing ending monitor is set for a MediaPlayer object of the installation application by calling a setOnCompletionListener function of the Android native player, and the playing ending monitor can monitor whether playing is ended in real time; and when the monitor for playing ending is set and the video source is modified to be played, automatically recompiling and installing the video playing application. Preferably, in this embodiment, when a play end listener is set for the video application, in a native player of an Android system, a modified code in a play end scene is run to implement that the play listener is added to the video play application.
In specific implementation, when a user plays a video by using a newly installed video playing application, the Android system monitors playing through a monitoring playing interface, after the playing is finished, a code in a playing finishing scene in the source code of the Android player runs, playing related information is obtained through a playing video source function, and the playing related information including the current playing progress, the packet name of the playing application, the packet name of the playing interface, playing movie information and the like is inserted into a historical database.
When a user opens the historical database, all stored playing information can be searched from the historical database, the playing information is displayed in a preset historical viewing interface, the historical database is opened, when the user wants to continue to view the last video next time, a playing instruction is input, after the intelligent terminal receives the corresponding playing instruction, the name of an application package played by the video is obtained according to the playing information in the historical viewing page, the package name and the playing information of the video playing interface can be opened by starting the interface through the Android interface, and therefore the user can enter the playing interface from the historical interface.
In order to better understand the technology of the present invention, the present invention further provides a specific application example, as shown in fig. 2, which specifically includes the following steps.
Step 202, the native player modifies the playing ending scene.
And step 204, analyzing the newly installed interface of the third-party application.
And step 208, monitoring that the playing is finished.
And step 209, acquiring the playing information.
And step 211, finishing.
Based on the above embodiment, the present invention further provides an intelligent terminal, and a schematic block diagram thereof may be as shown in fig. 3. The intelligent terminal comprises a processor, a memory, a network interface, a display screen and a temperature sensor which are connected through a system bus.
