I am implementing file uploading concept through gallery,camera and filemanager.
Here is the code
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
// CALL THIS METHOD TO GET THE URI FROM THE BITMAP
Uri tempUri = getImageUri(getApplicationContext(), photo);
// CALL THIS METHOD TO GET THE ACTUAL PATH
File finalFile = new File(getRealPathFromURI(tempUri));
suppdocs.setText(strPath);
} else if (requestCode == 2) {
Bitmap bm=null;
if (data != null) {
try {
bm = MediaStore.Images.Media.getBitmap(getApplicationContext().getContentResolver(), data.getData());
} catch (IOException e) {
e.printStackTrace();
}
}
Uri tempUri = getImageUri(getApplicationContext(), bm);
File finalFile = new File(getRealPathFromURI(tempUri));
suppdocs.setText(strPath);
} else if (requestCode == 3) {
Uri uri = data.getData();
strPath= getPath(getApplicationContext(),uri);
suppdocs.setText(strPath);
}
}
}
Here is the code to get path for selected file from filemanager

I tried to upload images to server through camera,gallery and filemanager its working properly but when i select pdf file through filemanage i am getting SSL Exception.
Expected output:
If i select pdf files through file manager it should upload pdf files properly

I'm trying to get a pdf file from my android storage, but everytime it returns null.
It already works with image files, but when i try to get a pdf file it always returns null.
I'm already able to select the pdf file. On onActivityResult i'm able to get the uri from data, but the path is wrong ("content://com.android.providers.media.documents/document/document%3A140"), so i'm trying to get the full path using getPath method, but like i said before, it always returns null.
This code must work with android version >= Android 6.0 (Sdk 23).

Thanks for the answers.
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.
#Override
public void onActivityResult(int req, int res, Intent imageIntent) {
super.onActivityResult(req, res, imageIntent);
switch (req) {
case SELECT_ICON:
if (res == RESULT_OK) {
try {
final Uri iconUri = imageIntent.getData();
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 used these methods to get path from URI
private String getActualFilePath(Context context, Uri fileUri) throws URISyntaxException{
Uri uri = Uri.parse(fileUri);
final boolean needToCheckUri = Build.VERSION.SDK_INT >= 19;
String selection = null;
String[] selectionArgs = null;
// Uri is different in versions after KITKAT (Android 4.4), we need to
// deal with different Uris.

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);
}
}
Please help me where I am wrong.

I need to read a file selected by user, so I use this code:
//This code is called by a button to ask the permission
private void startUpload(){
if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, WRITE_PERMISSION_GRANTED);
} else {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, WRITE_PERMISSION_GRANTED);
}
}
}//startUpload
I put the relative permission in the manifest too:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
I read the file in this way:
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case WRITE_PERMISSION_GRANTED: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
try {
FileInputStream stream = new FileInputStream(toUpload.getCanonicalFile());
byte[] data = new byte[(int) toUpload.length()];
stream.read(data);
stream.close();
Log.e("FUNZIONA!!!!", "OK!");
}catch (Exception e){
Log.e("ECCEZIONE", e.getMessage());
}
} else {
Log.e("PERMISSION", "DEINED");
}
return;
}
// other 'case' lines to check for other
// permissions this app might request
}
}
(toUpload is a file selected by the user with the file manager, in this case a downloaded image)
With the code I get this exception:
/data/data/com.android.browser/cache/2016-04-25-17-17-49-1205395195.jpg: open failed: EACCES (Permission denied)
I don't know what the problem is.
I add some details:

You are not the author of the com.android.browser app. You cannot access that app's files on internal storage. Your permissions are for external storage.
ok, I solved it! The problem was in part the emulator ... I post the code for those who had the same problem (thanks to CommonsWare for help):

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));

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
