android調用本地錄制程序獲取錄制文件路徑的問題(摘) – Android移動開發技術文章_手機開發 Android移動開發教學課程

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.
Trick is to insert media into database before recording:
String fileName = "captureTemp.mp4";  
ContentValues values = new ContentValues();  
values.put(MediaStore.Video.Media.TITLE, fileName);  
cameraVideoURI = getContentResolver().insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, values);  
Intent intent = new Intent(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); 
       String recordedVideoFilePath = cursor.getString(column_index_data);
       int recordedVideoFileSize = cursor.getInt(column_index_size);
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:
protected void 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 = new File(Environment.getExternalStorageDirectory(),"VideoFile.3gp"); 
    FileOutputStream fos = new FileOutputStream(tmpFile);
    byte[] buf = new byte[1024];
    int len;
    while ((len = > 0) {
        fos.write(buf, 0, len);
  } catch (IOException io_e) {
    // TODO: handle error
The MediaStore.EXTRA_OUTPUT and the Uri aren't necessary in this case.
