Obtain said daily record process recorded logs through the log acquisition function that calls said daily record process object instance.
Further, said method is specially:
Obtain process through the host process starting log, said log acquisition process through when operation interface function obtain the object instance of the daily record process that Android operating system carries;
The log acquisition function that said log acquisition process is at first called said daily record process object obtains all log records that said daily record process has generated, and sends the log record that obtains to said host process;
After said log acquisition process is obtained the log record of having preserved, monitor said daily record process in real time and whether generate new log record, when new log record produces, send the log record that newly produces to said host process.
Further, said method also comprises:
Said log record is filtered, judge whether comprise specified services and/or key in application word in every log record,, otherwise abandon this log record if comprise then obtain this log record.
Further, after said host process was receiving said log record, said method also comprised:
Show said log record, said log record is stored on the storage card through menucommand.
Further, the daily record process that carries of described Android operating system is the logcat process.
Based on said method, the present invention also proposes a kind of Android terminal and obtains the device of daily record, and this device comprises:
Log acquisition process module, be used for through when operation interface function obtain the object instance of the daily record process that Android operating system carries, and obtain said daily record process recorded logs through the log acquisition function that calls said daily record process object instance;
The host process module is used to start said log acquisition process module, receives the log record that said log acquisition process module transmits.
Further, the log acquisition function that said log acquisition process module is at first called said daily record process object obtains all log records that said daily record process has generated, and sends the log record that obtains to said host process module;
Said log acquisition process module also is used for monitoring in real time said daily record process and whether generates new log record, when new log record produces, sends the log record that newly produces to said host process module.
Further, said log acquisition process module also is used for the log record that obtains is filtered, and judges whether comprise specified services and/or key in application word in every log record, if comprise then keep this log record, otherwise abandons this log record; Send the log record that filters out to said host process module at last.
Further, also be used to show said log record, and provide menucommand to store said log record in said host process module.
The present invention through when operation interface function obtain the object instance of the daily record process that Android operating system carries; And obtain said daily record process recorded logs through the log acquisition function that calls said daily record process object instance, after obtaining log record, show and store through host process.The present invention can realize checking of log record that system and/or application program produce and show that the technical matters that need carry out program debug by PC of solution has improved development efficiency on the terminal.

Fig. 1 obtains the method flow diagram of daily record for the present invention;
Fig. 2 obtains the device process flow diagram of daily record for the present invention.
Embodiment
For making the object of the invention, technical scheme and advantage clearer, below lift embodiment and with reference to accompanying drawing, to further explain of the present invention.
Fig. 1 is the method flow diagram that on the terminal, obtains daily record provided by the invention, and this method comprises:
Step 100, obtain the object instance of the daily record process (logcat) that Android operating system carries;
Interface (Runtime) obtains the object instance of the daily record process that Android operating system carries during operation that the log acquisition process provides through Android operating system; It is the logcat object instance; The logcat process is a system process, is used for obtaining in real time operating system and application log information.
The method instance that obtains said logcat object instance is following:
Runtime.getRuntime().exec(“logcat”)
Step 102, after getting access to the logcat object instance, the member function through the logcat object obtains the log record that system has produced;
Can obtain log information through the member function GetInputStream () that obtains inlet flow of logcat object;
Step 104, log acquisition process are filtered the log information that gets access to, and obtain the log record of specified services and/or application, send host process to;
The method of filtering can adopt following method: the log information that obtains is input in the tabulation class; Search function through the tabulation class judges whether comprise specified services and/or key in application word in every log record; If comprise then obtain this log record, otherwise abandon this log record.
Step 106, host process show log obtain the log record that process transmits, and can preserve the log record that obtains through the menucommand that provides for the user.
Preferably, the method for the invention also comprises the steps:
Whether step 108, said log acquisition the process said logcat process of monitoring in real time produce new log record; If produce new log record; Then it is filtered; If the log record of said new generation satisfies filtercondition, the log record that then will newly produce is real-time transmitted to host process, and host process shows after receiving the log record of new generation in real time.
In order to realize above-mentioned method embodiment, other embodiment of the present invention also provide a kind of Android terminal to obtain the device of daily record, and are as shown in Figure 2.What need at first explanation is; Because following embodiment is for realizing aforesaid method embodiment; So the module in this base station controller all is to establish for each step that realizes preceding method; But the present invention is not limited to following embodiment, and any device of said method and module of realizing all should be contained in protection scope of the present invention.And in the following description, the content identical with preceding method omitted at this, to practice thrift length.
