I am trying to upload a PDF file to server but am getting a Null toast according to my method , i tested the file path in a TextView is visible but when it comes to uplaoding it seems not seeing the PDF file , am using ion library. Below is my code sample.
public void uploadFile(final String selectedFilePath){
final ProgressDialog pd;
pd = new ProgressDialog(MainActivity.this);
pd.setMessage("Uploading ...");
pd.setCancelable(false);
pd.show();
//File file = new File(this.getFilesDir().getAbsolutePath() + "/thesubdirectory/the.zip");
File f = new File(getApplicationContext().getFilesDir().getAbsolutePath()+selectedFilePath);
try {
RandomAccessFile rf = new RandomAccessFile(f, "rw");
rf.setLength(1024 * 1024 * 2);
} catch (Exception e) {
System.err.println(e);
}
File echoedFile = getFileStreamPath("echo");
Ion.with(MainActivity.this)
.load(SERVER_URL)
.uploadProgressDialog(pd)
.setMultipartFile("uploaded_file",f)
.write(echoedFile)
.setCallback(new FutureCallback<File>() {
#Override
public void onCompleted(Exception e, File result) {
try {
Toast.makeText(MainActivity.this, " " + result, Toast.LENGTH_LONG).show();
System.out.println("Error " + result);
pd.dismiss();
} catch (Exception e1) {
System.out.println("Error " + e1);
}
pd.dismiss();
}
});
}
This is the rest of code.

This is the filepath class which returns file path of Gallery image/ Document / Video / Audio
That class is a piece of junk. It will not work for many Uri values on any Android device, let alone those devices where the "rules" encoded in that class have changed, due to manufacturer alterations or OS updates.
Moreover, none of those locations are inside of getFilesDir().
Use the Uri properly: use a ContentResolver and openInputStream() to get an InputStream on the content identified by the Uri. Either pass that InputStream to Ion (if it supports uploading from a stream), or use the stream to make a local copy of the content (e.g., into getCacheDir()), then upload the local copy.

I want to get the path of a file(pdf in this case).
I tried myFile.getAbsolutePath() and uri.getPath() but instead of returning /storage/emulated/0/Download/dummy.pdf it returns /com.android.providers.downloads.documents/document/8 .
I couldn't find a working solution for this problem so instead I used FilePath.getPath(context, uri) .
It was working perfectly fine but after a few runs it stopped working and gave me exception :
java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1, result=-1, data=Intent { dat=content://com.android.providers.downloads.documents/document/msf:31 flg=0x1 }} to activity {com.example.pm/com.example.pm.UploadFileActivity}: java.lang.NumberFormatException: For input string: "msf:31"
And that's why I don't like using FilePath.
Anybody have any Idea why in the first place I'm not getting the correct path (it worked before) and how can I fix this problem? If not is there any other way that I can get the file path being 100% sure that it always works?
I would appreciate your help in advance. thanks.

I have a code to get an image if I click the button, in my problem, I wanna get the URI/path of the image and send it into the database, after that I wanna show it in ImageView. And this is my code.

switch (req) {

final String imgUri = iconUri.toString();
final InputStream iconStream = getContentResolver().openInputStream(iconUri);
final Bitmap selectedIcon = BitmapFactory.decodeStream(iconStream);
imageView.setImageBitmap(selectedIcon);
saveButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
String tname = text1.getText().toString();
String date = textView.getText().toString();
String priority = spinner1.getSelectedItem().toString();
String notes = text2.getText().toString();
String path = imgUri;
dbHelper.addTask(new Task(tname, date, priority, notes, path));
Toast.makeText(getApplicationContext(), "Success!!!", Toast.LENGTH_LONG).show();
TaskListActivity.tasklist.RefreshList();
finish();
}
});
} catch (FileNotFoundException err) {
err.printStackTrace();

You can use String strUri = uri.toString() to convert Uri to String save this strUri to database and while retrieving from database you can use Uri uri = Uri.parse(strUri) for converting string back to Uri

I am trying to read a PDF file but it's throwing a NoSuchFileException. I have seen some solution for this but nothing seems to work in my case. I want to read the PDF file. Below is my code:
private void requestForResume() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
Intent chooser = Intent.createChooser(intent, "Upload PDF File");
startActivityForResult(chooser, REQUEST_CODE);
}
Here is how I am converting to file:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE) {
Uri uri = data.getData();
String fileName = uri.getLastPathSegment();
File resumeFile=new File(uri.getPath());
try {
PDDocument pdfResume=PDDocument.load(resumeFile);
PDFTextStripper stripper=new PDFTextStripper();
String resumeText=stripper.getText(pdfResume);
Log.d("location",resumeText);
} catch (IOException e) {
Log.d("location","unable to load pdf"+e.toString());
}
fileEditText.setText(fileName);
}
}

I am creating an app which uploads a selected image from the gallery and uploads it to a web service. The webservice requires the filename of selected image plus a base64 encoding of the file contents. I have managed to achieve this with a hardcoded file path. However, I am struggling to get the real filepath of the image. I have read around the web and have this code, but it does not work for me:
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
String[] projection = {MediaStore.Images.Media.DATA};
try {
Cursor cursor = getContentResolver().query(selectedImageUri, projection, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(projection[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
Log.d("Picture Path", picturePath);
}
catch(Exception e) {
Log.e("Path Error", e.toString());
}
}
}
I get this error:
java.lang.NullPointerException
EDIT
Forgot to mention I am using Kitkat. It looks like my problem is KitKat related. I found this (see below) which helped me get my app working:
Android Gallery on KitKat returns different Uri for Intent.ACTION_GET_CONTENT
A little late to the party but here's my code, hope this helps.
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData( );
String picturePath = getPath( getActivity( ).getApplicationContext( ), selectedImageUri );
Log.d("Picture Path", picturePath);
}
}
public static String getPath( Context context, Uri uri ) {
String result = null;
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = context.getContentResolver( ).query( uri, proj, null, null, null );
if(cursor != null){
if ( cursor.moveToFirst( ) ) {
int column_index = cursor.getColumnIndexOrThrow( proj[0] );
result = cursor.getString( column_index );
}
cursor.close( );
}
if(result == null) {
result = "Not found";
}
return result;
}
Use below code,
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
String s = getRealPathFromURI(selectedImageUri);
editText1.setText(s);
}
}
and below is your getRealPathFromURI function,
public String getRealPathFromURI(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
#SuppressWarnings("deprecation")
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
Try this:
Uri selectedImageURI = data.getData();
imageFile = new File(getRealPathFromURI(selectedImageURI));
And
private String getRealPathFromURI(Uri contentURI) {
Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null) { // Source is Dropbox or other similar local file path
return contentURI.getPath();

If you are like me and you dont have a local file ready, for instance you want to give user a chance to take a picture and then upload the picture this is how to do it.
I am a noob in java but i have allot of experience in coding.
Stackoverflow helped me allot so now it is my time to do something back.
Under class activity you have to declare these two items.
asuming you have a working upload class and php script.
NOTE i am not taking any consideration about all the different API's
out there. I am using java compiler 1.7 and a API range of 10 to 18.
public class Yourproject extends Activity {
File imageFile;
File imageFileName;
//This part is needed for decoding the path adres.
private String getRealPathFromURI(Uri contentURI) {
String result;
Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null) { // Source is Dropbox or other similar local file path
result = contentURI.getPath();
} else {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME);
result = cursor.getString(idx);
cursor.close();
}
return result;
}
//This is needed for the path name, now you might just want to use one decoding script depending on //your class in total.
//In my case this was the way to go.
//To use one single addres use this line ImageColumns.DATA in the int idx declaration.
private String getRealPathFromNAME(Uri contentNAME) {
String result;
Cursor cursor = getContentResolver().query(contentNAME, null, null, null, null);
if (cursor == null) { // Source is Dropbox or other similar local file path
result = contentNAME.getPath();
} else {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DISPLAY_NAME);
result = cursor.getString(idx);
cursor.close();
}
return result;
}
//Then under protected void onCreate(Bundle savedInstanceState) you place this code to get
//the image and process it.
#Override
protected void onCreate(Bundle savedInstanceState) {
//declare the ImageView
final ImageView inputPicture = (ImageView) findViewById(R.id.imageView2);
inputPicture.setImageURI((Uri) getIntent().getExtras().get("picture"));
//here where recieve the image from last page "Putextra" method
try {
//here we will get the data and proces it trough to get the real
//address for uploading.
//This is send from a other activity with a Intent.EXTRA_STREAM
//The code looks like this:
/*********"Putextra"*********/
//final ImageView iv = (ImageView) findViewById(R.id.imageView1);
//final Uri thumb = (Uri) getIntent().getExtras().get(Intent.EXTRA_STREAM);
//iv.setImageURI(thumb);
//Sending it to the next activity
//it.putExtra("picture", thumb);
/*********"Putextra"*********/
Uri fileUri = (Uri) getIntent().getExtras().get("picture");
//get
//Uri fileName = (Uri) getIntent().getExtras().get("picture");
//get
imageFile = new File(getRealPathFromURI(fileUri));
//send
imageFileName = new File(getRealPathFromNAME(fileUri));
//send
//i got a exeption Uri fileName, use fileUri twice..
} catch (Exception e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
}
//here we will declare the name for furter processing.
final File uploadFilePath = imageFile;
final File uploadFileName = imageFileName;
}
And the rest i will leave up to u, if you got this far, I am pretty sure you will finish.
Try this,
file = new File(getPath(outputFileUri));
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
#SuppressWarnings("deprecation")
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
Hope this helps you
