がどのように見えますビデオキャプチャはファイルuriのみで動作し、コンテンツuriでは動作しません。

同じ問題がありますか？あなたはいくつかの一般的な解決策を提案できますか？

Answer 1

これは、私を助け：

Uri uri; 
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { 
     uri = FileProvider.getUriForFile(context, context.getApplicationContext().getPackageName() + ".provider", f); 
    } else { 
     uri = Uri.fromFile(f); 
    } 
    intent.putExtra(MediaStore.EXTRA_OUTPUT, uri); 

Answer 2

これは私のために働いています。

private void launchCamera() { 

    Intent captureVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); 
    if (captureVideoIntent.resolveActivity(getPackageManager()) != null) 
    { 
     Uri videoUri = null; 
     try { 
      videoUri = getOutputMediaFileUri(); 
     } catch (Exception ex) { 
      // Error occurred while creating the File 
      ex.printStackTrace(); 
     } 

     // Continue only if the File was successfully created 
     if (videoUri != null) { 
      captureVideoIntent.putExtra(MediaStore.EXTRA_OUTPUT, videoUri); 
      startActivityForResult(captureVideoIntent, REQUEST_CAMERA); 
     } 
    } 
} 

/** 
* Creating file uri to store image/video 
*/ 
private Uri getOutputMediaFileUri() { 
    if(Build.VERSION.SDK_INT >= 24) { 
     // For android N you need to use the file provider 
     return FileProvider.getUriForFile(this, getResources().getString(R.string.file_provider_name), getOutputMediaFile()); 
    } else { 
     return Uri.fromFile(getOutputMediaFile()); 
    } 
} 


/** 
* returning file to store image/video 
*/ 
private File getOutputMediaFile() { 
    // External sdcard location 
    File mediaStorageDir = new File(
      Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), 
      "DirectoryNameWhereYouWantToStore"); 

    // Create the storage directory if it does not exist 
    if (!mediaStorageDir.exists()) { 
     if (!mediaStorageDir.mkdirs()) { 
      Log.d(TAG, "Oops! Failed to create directory"); 
      return null; 
     } 
    } 

    // Create a media file name 
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date()); 
    return new File(mediaStorageDir.getPath() + File.separator + "IMG_" + timeStamp + ".mp4"); 
}
