File not found exception (Path from URI)
I'm trying to get a FileInputStream object for the picture a user selects from their gallery and when I'm trying to open the file from the URI I receive, it keeps saying FileNotFoundException...
Here's the code I'm using to fire off the intent for picking an image from the gallery:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
And here's the code I use for catching onActivityResult:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri uri = data.getData();
File myFile = new File(uri.getPath());
FileInputStream fiStream = new FileInputStream(myFile);
...
}
}
Right on the creation of the FileInputStream, I get the folloiwng error upon choosing one of my photos via the emulator:
W/System.err: java.io.FileNotFoundException: /document/image:26171: open failed: ENOENT (No such file or directory)
Maybe I'm retrieving the file from the URI incorrectly??? Any help here would be greatly appreciated, thanks!!
Solution
I ended up using https://android-arsenal.com/details/1/2725 It's very easy to use!
Answer
I had the exact same issue.
My problem I was using this code
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null){
Uri uri = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), uri);
until when I found out it could not handle a bigger image. I had to change and use another method to get the image.
Using InputStream
File file= new File(uri.getPath());
FileInputStream inputStream= new FileInputStream(file);
This gives a file not found exception for the path format is the reason
As Knossos said
"The Uri that you are attempting to open is content://document/image:26171. You need to access it with a ContentProvider
Thanks to Paul Burke with his library aFileChooser http://github.com/iPaulPro/aFileChooser
To make it simple just create a class I called it FileChooser.java

Then we can simply access it in our activity result
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null){
Uri uri = data.getData();
try {
InputStream in = new FileInputStream(FileChooser.getPath(getContext(),uri));
As I wanted to resize the image before using it there is the full code... I hope it helps someone...;) Thanks to blubl
@Override

try {
/*Bitmap bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), uri);*/
InputStream in = new FileInputStream(FileChooser.getPath(getContext(),uri));
int dstWidth = 1980;
int dstHeight = 960;
int inWidth, inHeight;
//get image size
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;

float[] values = new float[9];
m.getValues(values);
