I have a image uri and I want to edit that image and obtain the new Image uri. After some searching I found this piece of code and tries to apply.
Intent editIntent = new Intent(Intent.ACTION_EDIT);
editIntent.setDataAndType(uri, "image/*");
editIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivityForResult(Intent.createChooser(editIntent, null), 222);
When I try to receive in callbacks I get null in data.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
System.out.println("REQUEST_CODE: " + requestCode + " " + resultCode + " " + data.getData());
}
So how to get the new image uri or is there any other way to do this?
ACTION_EDIT is not designed for use with startActivityForResult(), as there is no result. See the documentation, particularly the "Output: nothing" portion.
What the other app does with the Uri is up to the other app. It might save changes to the original content identified by the Uri that you gave it, or it might not. If it elects to save changes to some new content, there is no means for you to find out where those changes were saved.

I am trying to fetch a file this way:
final Intent chooseFileIntent = new Intent(Intent.ACTION_GET_CONTENT);
String[] mimetypes = {"application/pdf"};
chooseFileIntent.setType("*/*");
chooseFileIntent.addCategory(Intent.CATEGORY_OPENABLE);
if (chooseFileIntent.resolveActivity(activity
.getApplicationContext().getPackageManager()) != null) {
chooseFileIntent.putExtra(Intent.EXTRA_MIME_TYPES, mimetypes);
activity.startActivityForResult(chooseFileIntent, Uploader.PDF);
}
Then in onActivityResult :
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
}
According to many threads I'm supposed to fetch the file name from the intent with data.getData().getPath(), the file name I'm expecting is my_file.pdf, but instead I'm getting this :
/document/acc=1;doc=28
So what to do? Thanks for your help.

Not with that code. That code is asking the user to pick a piece of content. This may or may not be a file.

That was never correct, though it tended to work on older versions of Android.
So what to do?
Well, that depends.
If you wish to only accept files, integrate a file chooser library instead of using ACTION_GET_CONTENT. (UPDATE 2019-04-06: since Android Q is banning most filesystem access, this solution is no longer practical)
If you are willing to allow the user to pick a piece of content using ACTION_GET_CONTENT, please understand that it does not have to be a file and it does not have to have something that resembles a filename. The closest that you will get:
If getScheme() of the Uri returns file, your original algorithm will work
If getScheme() of the Uri returns content, use DocumentFile.fromSingleUri() to create a DocumentFile, then call getName() on that DocumentFile — this should return a "display name" which should be recognizable to the user
To get the real name and to avoid getting a name that looks like "image: 4431" or even just a number, you can write code as recommended by CommonsWare.
The following is an example of a code that selects a single pdf file, prints its name and path to the log, and then sends the file by email using its uri.
private static final int FILEPICKER_RESULT_CODE = 1;
private static final int SEND_EMAIL_RESULT_CODE = 2;
private Uri fileUri;
private void chooseFile() {
Intent fileChooser = new Intent(Intent.ACTION_GET_CONTENT);
fileChooser.setType("application/pdf");
startActivityForResult(Intent.createChooser(fileChooser, "Choose one pdf file"), FILEPICKER_RESULT_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == FILEPICKER_RESULT_CODE) {
if (resultCode == RESULT_OK) {
fileUri = data != null ? data.getData() : null;
if (fileUri != null) {
DocumentFile d = DocumentFile.fromSingleUri(this, fileUri);
if (d != null) {
Log.d("TAG", "file name: " + d.getName());
Log.d("TAG", "file path: " + d.getUri().getPath());
sendEmail(fileUri);
}
}
}
}
}
private void sendEmail(Uri path) {
String email = "example#gmail.com";
Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setType("application/octet-stream");
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "PDF file");
String[] to = { email };
intent.putExtra(Intent.EXTRA_EMAIL, to);
intent.putExtra(Intent.EXTRA_TEXT, "This is the pdf file...");
intent.putExtra(Intent.EXTRA_STREAM, path);
startActivityForResult(Intent.createChooser(intent, "Send mail..."), SEND_EMAIL_RESULT_CODE);
}
hope it helps.

I getting an URI when try to pick a file :
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent,FILE_MANAGER_REQUEST_CODE);
In ActivityOnResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d("FilePick", "request code = " + requestCode + ", resultCode = " + resultCode);
Log.d("FilePick", "Intent = " + data != null ? data.getData().getPath() : null);
super.onActivityResult(requestCode, resultCode, data);
}
When i pick a file data.getData().getPath() returns
/external/file/15499
How i convert it to real file path?
Note: I read this topics :
Get filename and path from URI from mediastore
Get real path from URI, Android KitKat new storage access framework
But i think it's accessible onl;y for media content. Not for files.
There is no "real file path". A Uri is not a File.
Please use ContentResolver and methods like openInputStream() to consume the content.
I have been researching on this but I am not able to find an answer for this.
I am picking an image from the gallery using media store intent and I am able to get the image file path in onActivityResult method. (I know how to get the URI in the intent and filepath).
I am passing in some intent extras on starting the activity (startActivityForResult) but all the intent extras are null.
Code snippets (in case):
This is my onActivityResult code which is working and i get the image path
/* On activity result from image button */
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
System.out.println("Result Code" + resultCode);
if(requestCode == FavoriteListAdapter.IMAGE_PICK_CODE && data != null && data.getData() != null && resultCode == FragmentActivity.RESULT_OK) {
Uri _uri = data.getData();
//User had pick an image.
Cursor cursor = getContentResolver().query(_uri, new String[] { android.provider.MediaStore.Images.ImageColumns.DATA }, null, null, null);
cursor.moveToFirst();
//Link to the image
String imageFilePath = cursor.getString(0);
System.out.println("imagefilepath" + imageFilePath);
System.out.println(data.getStringExtra("exp"));
cursor.close();
}
}
I am starting my activity with startActivityForResult
Intent imageIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
imageIntent.setType("image/*");
imageIntent.putExtra("exp", "testing");
((FragmentActivity)view.getContext()).startActivityForResult(imageIntent, IMAGE_PICK_CODE);
I should be able to get the string "testing" in onActivityForResult but all I get is null.
Any ideas and suggestions will be appreciated. THnkas a lot.
Actually I figured it out .. When you are sending an intent to a system activity like MediaStore or the camera etc... the onActivityResult will not have the intent extras you sent while calling the activity.
This is probably by design and will only contain the extras given by the system activity. For instance after picking an image from the gallery, the returning intent from the gallery will only the URI containing the image path.
Same goes to camera or any system activites.
There's lots of questions on the same topic, however none of them provided me an answer.
I've tried a lot of solutions, yet none of them is working for me so far.
I'm invoking the camera intent in a fragment and inserting uri to the newly created file where I want the picture to be stored and then on activityresult I'm passing the uri to a new activity where I want to show it in an imageview and then proceed to upload it.
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File mImageFile = new File(Environment.getExternalStorageDirectory().getPath()+"/DCIM/" + "Camera/" + File.separator+System.currentTimeMillis()+".jpg");
imageUri = Uri.fromFile(mImageFile);
Log.d("camera", "imageUri: " + imageUri.toString());
intent.putExtra(MediaStore.EXTRA_OUTPUT,imageUri);
startActivityForResult(intent, CAMERACODE);
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode){
case CAMERACODE:{
if (resultCode == Activity.RESULT_OK) {
Intent intent = new Intent(getActivity(), SubmitActivity.class);
intent.putExtra("imageuri", imageUri.toString());
getActivity().startActivity(intent);
and in SubmitActivity:
Bundle extras = getIntent().getExtras();
imageUri = extras.getString("imageuri"); <-- imageUri has the correct path, and the actual file is created and the photo is there. The photo is not showing up on gallery for some reason though, only when browsing the folders. What is the reason for this?
iv = (ImageView) findViewById(R.id.selectedpicture);
iv.setImageURI(Uri.parse(imageUri)); <-- this line causes a NullPointerException.
Can anyone explain the reason for why the setImageURI fails? Any alternative way of doing this? I'm using Samsung Galaxy S3
I believe iv is null and there is no problem with imageuri.
Check whether you have done setContentView and check if the layout has selectedpicture imageView.
Edit:
The photo is not showing up on gallery for some reason though
Gallery uses MediaStore to get all the photos on the sdcard. But when you take a picture MediaStore db would not have been updated. For the pic to show up in gallery MediaScanning should be run. Check this post
