I want to develop an application on android phone regarding voice recorder. I have to record a sound for about 30 seconds and then stop and save the recorded sound in gallery. Can anyone post the code if you have please?

推荐答案

还有就是的如何在Android开发者文档使用 MediaRecorder 做音频捕捉的例子。

There is an example of how to do audio capture using MediaRecorder in the Android Developer Documentation.

我会建议节省SD卡中的文件，然后让您的画廊code。检查SD卡，看看哪些文件显示。您可以使用获得SD卡的目录中的<一个href="http://developer.android.com/intl/de/reference/android/os/Environment.html#getExternalStorageDirectory%28%29"><$c$c>Environment.getExternalStorageDirectory()法。这将是最好的保存在SD卡根目录下的子目录文件。

I would recommend saving the files on the SD Card and then have your gallery code check the SD card to see which files to display. You can get the directory of the SD Card using the Environment.getExternalStorageDirectory() method. It would be best to save your files in a subdirectory of the SD Card root directory.

请确保您给你的应用程序的权限就需要 。至少，这将需要<一个href="http://developer.android.com/intl/de/reference/android/Manifest.permission.html#RECORD_AUDIO"><$c$c>RECORD_AUDIO和<一href="http://developer.android.com/intl/de/reference/android/Manifest.permission.html#WRITE_EXTERNAL_STORAGE"><$c$c>WRITE_EXTERNAL_STORAGE.

Make sure you give your applications the Permissions it will need. At the very least it will need RECORD_AUDIO and WRITE_EXTERNAL_STORAGE.
