android调用本地录制程序获取录制文件路径的问题（摘）

I use the MediaStore.ACTION_VIDEO_CAPTURE intent class to capture the video, the video stored in default location(gallery),i want to store the video in specific location with specific name.

I use MediaStore.EXTRA_MEDIA_TITLE and MediaStore.EXTRA_MEDIA_OUTPUT but I don`t get the video at correct location, at least I need the path of recorded video.

 方案一：

Trick is to insert media into database before recording:

String fileName ="captureTemp.mp4";    ContentValues values =newContentValues();    values.put(MediaStore.Video.Media.TITLE, fileName);    cameraVideoURI = getContentResolver().insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, values);      Intent intent =newIntent(MediaStore.ACTION_VIDEO_CAPTURE);    intent.putExtra(MediaStore.EXTRA_OUTPUT, cameraVideoURI);    intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY,0);  intent.putExtra(MediaStore.EXTRA_SIZE_LIMIT, MAXIMUM_VIDEO_SIZE);                 startActivityForResult(intent, CAPTURE_VIDEO_INTENT);  

and then onActivityResult() use saved cameraVideoUri to reference recorded video:

       String[] projection ={MediaStore.Video.Media.DATA,MediaStore.Video.Media.SIZE  };          Cursor cursor = managedQuery(cameraVideoURI, projection,null,null,null);          int column_index_data = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);          int column_index_size = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.SIZE);          cursor.moveToFirst();          String recordedVideoFilePath = cursor.getString(column_index_data);         int recordedVideoFileSize = cursor.getInt(column_index_size);  

方案二：

The solution from Zelimir doesn't work in my case (the videos were at the right location but had a size of zero bytes). So i've found another solution:

protectedvoid onActivityResult(int requestCode,int resultCode,Intent intent){    super.onActivityResult(requestCode, resultCode, intent);      if(resultCode != RESULT_OK)return;      try{      AssetFileDescriptor videoAsset = getContentResolver().openAssetFileDescriptor(intent.getData(),"r");      FileInputStream fis = videoAsset.createInputStream();      File tmpFile =newFile(Environment.getExternalStorageDirectory(),"VideoFile.3gp");       FileOutputStream fos =newFileOutputStream(tmpFile);        byte[] buf =newbyte[1024];      int len;      while((len = fis.read(buf))>0){          fos.write(buf,0, len);      }             fis.close();      fos.close();    }catch(IOException io_e){      // TODO: handle error    }  

}

The MediaStore.EXTRA_OUTPUT and the Uri aren't necessary in this case.
