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 usingopenInputStream()to work with aUri, 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 usingopenInputStream()to work with aUri, 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.
