Android: get uri realpath return null










0














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.
