The code below uploads a file for an user. How can I fix it? I selected a file from my drive and data.getData() is not null, but get real path does not work:



protected void onActivityResult(int requestCode, int resultCode, Intent data) 
 if (resultCode == RESULT_OK) 
 Uri uri = data.getData();
 Log.i("errorCheck","L: "+getPath(this, uri));
 


public static boolean isExternalStorageDocument(Uri uri) 
 return "com.android.externalstorage.documents".equals(uri.getAuthority());
 
 public static boolean isDownloadsDocument(Uri uri) 
 return "com.android.providers.downloads.documents".equals(uri.getAuthority());
 
 public static boolean isMediaDocument(Uri uri) 
 return "com.android.providers.media.documents".equals(uri.getAuthority());
 

 public static String getDataColumn(Context context, Uri uri, String selection,
 String selectionArgs) 

 Cursor cursor = null;
 final String column = "_data";
 final String projection = 
 column
 ;

 try 
 cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs,
 null);
 if (cursor != null && cursor.moveToFirst()) 
 final int column_index = cursor.getColumnIndexOrThrow(column);
 return cursor.getString(column_index);
 
 finally 
 if (cursor != null)
 cursor.close();
 
 return null;
 

 public static String getPath(final Context context, final Uri uri) 

 final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
 Log.i("errorCheck", "KIT: "+isKitKat);
 // DocumentProvider
 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) 
 if (DocumentsContract.isDocumentUri(context, uri)) 
 // ExternalStorageProvider
 if (isExternalStorageDocument(uri)) 
 final String docId = DocumentsContract.getDocumentId(uri);
 final String split = docId.split(":");
 final String type = split[0];

 if ("primary".equalsIgnoreCase(type)) 
 return Environment.getExternalStorageDirectory() + "/" + split[1];
 

 // TODO handle non-primary volumes
 
 // DownloadsProvider
 else if (isDownloadsDocument(uri)) 

 final String id = DocumentsContract.getDocumentId(uri);
 final Uri contentUri = ContentUris.withAppendedId(
 Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));

 return getDataColumn(context, contentUri, null, null);
 
 // MediaProvider
 else if (isMediaDocument(uri)) 
 final String docId = DocumentsContract.getDocumentId(uri);
 final String split = docId.split(":");
 final String type = split[0];

 Uri contentUri = null;
 if ("image".equals(type)) 
 contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
 else if ("video".equals(type)) 
 contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
 else if ("audio".equals(type)) 
 contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
 

 final String selection = "_id=?";
 final String selectionArgs = new String 
 split[1]
 ;

 return getDataColumn(context, contentUri, selection, selectionArgs);
 
 
 else if ("content".equalsIgnoreCase(uri.getScheme())) 
 return getDataColumn(context, uri, null, null);
 else if ("file".equalsIgnoreCase(uri.getScheme())) 
 return uri.getPath();
 

 return null;


But it always returns null.

    Perhaps you should write a Stack Overflow question where you provide a Minimal, Complete, and Verifiable example showing what you tried with respect using openInputStream() to work with a Uri, explaining how you have demonstrated that "none of them work" and asking for help. Or, if you only want to work with files, use a file chooser library.

    Perhaps you should write a Stack Overflow question where you provide a Minimal, Complete, and Verifiable example showing what you tried with respect using openInputStream() to work with a Uri, explaining how you have demonstrated that "none of them work" and asking for help.
