The step that record data transmission, is saved in the mobile phone memory is as follows:
1) starts recording, set up file and file storage directory;
2) judge and to set up the whether success of file and file storage directory that if the unsuccessful step of setting up file and file storage directory of returning, if success, the recording thread writes recording data by the data input channel to cyclic buffer;
3) judge whether the recording data are saved in the cyclic buffer of pipeline;
4) if preserve recording data to the cyclic buffer failure, then judge whether deadlock, if be judged as deadlock then the storage of recording is failed; If judging does not have deadlock, the data output stream is read recording data from pipeline;
If successfully preserve recording data to cyclic buffer, then the data output stream is read recording data to pipeline;
5) recording data in the cyclic buffer is preserved recording data in the mobile phone memory immediately by storage recording thread;
6) judge whether storage space has expired or power down, if storage space, is then returned the recording thread writes the recording data to cyclic buffer by data input stream step less than also not power down;
If storage space is full or power down occurs, then finish recording.
Further, read operation and the write operation in the cyclic buffer of described interim preservation recording data all separated.

2, data can safely, in time and effectively transmission between two threads.
Description of drawings
Fig. 1 be the present invention record data transmission, be saved in the flow chart of steps in the mobile phone memory.
Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Recording data quick storage method in the Android of the present invention system, at the inner data pipe of setting up the data instantaneous transmission that is used to record of recording system, data pipe comprises data input channel and data output channel, on the data pipe basis, set up pipeline data stream mode, pipeline data stream comprises pipeline data inlet flow and pipeline data output stream, recording data in the recording thread are as the pipeline data inlet flow, be kept at by the data input channel in the cyclic buffer of system, recording data in the cyclic buffer are as the pipeline data output stream, pass to recording storage thread by the data output channel, be kept at immediately in the storer of mobile phone by the recording storage thread data of will recording.
As shown in Figure 1, the step that record data transmission, is saved in the mobile phone memory is as follows:
1) starts recording, set up recording file and recording file storage directory; To start recording thread and recording storage thread when starting recording simultaneously.
2) judge and to set up the whether success of recording file and recording file storage directory, if the unsuccessful step of setting up file and file storage catalogue of returning,
If success, the recording thread writes recording data by the data input channel to cyclic buffer;
3) judge whether the recording data are saved in the cyclic buffer of pipeline;
4) if preserve recording data to the cyclic buffer failure, then judge whether deadlock, if be judged as deadlock then the storage of recording is failed; If judging does not have deadlock, read recording data by the data output channel;
If successfully preserve the recording data to cyclic buffer, then read the recording data from the data output channel;
5) recording data of reading in the cyclic buffer is preserved recording data in the mobile phone memory immediately by storage recording thread;
6) judge whether storage space has expired or power down, if storage space, is then returned the recording thread writes the recording data to cyclic buffer by data input stream step less than also not power down;
If storage space is full or power down occurs, then finish recording.
The recording of startup mobile phone, recording thread and recording storage thread start simultaneously, and interior read operation and the write operation of cyclic buffer of temporarily preserving recording data all separates.By pipeline data stream mode, recording on one side, on one side the real-time storage data, under the full situation of mobile phone power down or storage space, automatically stop recording, but the recording data under recording before mobile phone power down or storage space are full all have been kept in the storer, have avoided the recording loss of data that completely causes because of power down or storage space, and this preserving type does not consume the space, storage time is short, and the efficient height need not fringe cost.If run into recording by improper interruption, the recording substance of front still is kept at interim cyclic buffer, does not affect data output channel reading out data and pass to the recording storage thread in the extra buffer.Recording thread and two threads of recording storage thread guarantee that data can safely, in time and effectively transmission between it.
Wherein two data pipelines will be realized data transfer between recording thread and the storage recording thread, rather than between a thread the transmission of data because between a thread, carry out the transmission of data, might cyclic buffer be filled and completely cause thread deadlock; Have in the buffering area restricted portion read operation and write operation are separated, be convenient to so final sense data, and pass to storage recording thread.
