I am getting null when I display in TOAST.
I am running Lollipop.
Please could someone explain in detail on how to do this.
I am able to get the URI without any problems but my only issue is to not being able to convert it to a real path to store in my database.
Thanks
This problem occurs mainly for google native devices such as Nexus because in these devices the only image library is google photos. In google photos you get to choose not only those images which are present on your device but also those photos which are stored on cloud storage too. Try the below mentioned updated code of yours and let me know if it worked or not.
Your intent should have action as Intent.ACTION_GET_CONTENT
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == ATTACHMENT_PHOTO_GALLERY && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
nameView.setText(selectedImage.toString());
String realPath = getRealPathFromURI(this, selectedImage);
Toast.makeText(MainActivity.this, realPath, Toast.LENGTH_LONG).show();
}
}
public String getRealPathFromURI(Context context, Uri contentUri) {
Cursor cursor = null;
String path = null;
try {
String[] proj = {MediaStore.Images.Media.DATA};
cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
path = cursor.getString(column_index);
} finally {
if (cursor != null) {
cursor.close();
}
}
//The above code will fail to get file path if the file is selected from google photos.
//Then this will be the alternative approach
if (path == null && contentUri.toString().startsWith("content://com.google.android.apps.photos.content")) {
Bitmap requiredImage = null;
//Below key should be used for saving the newly downloaded image path as
//photoIdentificationKey as Key parameter and newly generated path as Value.
//An additional check should be implemented on your storage that whether any local
//path exists for corresponding photoIdentificationKey, if yes then use the existing
//local path else download new image.
String photoIdentificationKey = Uri.parse(contentUri.getLastPathSegment()).getLastPathSegment();
BitmapFactory.Options options = new BitmapFactory.Options();
InputStream inputStream;
try {
inputStream = getApplication().getContentResolver().openInputStream(contentUri);
requiredImage = BitmapFactory.decodeStream(inputStream, null, options);
//Save the newly downloaded image to your isolated storage and return the path
//on which this new image has been saved.
inputStream.close();
path = saveAndReturnPathForSavedImage(requiredImage);
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
return path;
}
private String saveAndReturnPathForSavedImage(Bitmap bmp) {
String path = Environment.getExternalStorageDirectory().toString();
OutputStream out = null;
File file = new File(path, "IMAGE"+ Calendar.getInstance().getTime()+".jpg"); // the File to save to
try {
out = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.PNG, 100, out);
} catch (FileNotFoundException e) {
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
return file.getPath();
}
If your Intent data data is not null then you can try this.
I've used this code to get image path from gallery, and its working in all devices.
Uri selectedImage = data.getData();
String[] filePath = {MediaStore.Images.Media.DATA};
Cursor c = getContentResolver().query(selectedImage, filePath, null, null, null);
c.moveToFirst();
int columnIndex = c.getColumnIndex(filePath[0]);
String picturePath = c.getString(columnIndex);
c.close();
Bitmap thumbnail = (BitmapFactory.decodeFile(picturePath));
Log.e("path of image from gallery......******************.........", picturePath + "");
Note: Be sure your data should not be null otherwise it will give NullPointerException.

how to get image from gallery which supports for API>=19 & API<19 both...
This code'll solve the problem for SDK < API11, SDK >= 11 && SDK < 19 and SDK > 19

Hope this will solve your Problem.
I'm trying to select image from gallery then convert this image to File and send it via HttpPost but I'm getting always FileNotFoundException. This my Code :
Selecting the photo
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK) {
if (requestCode == 1) {
// currImageURI is the global variable I’m using to hold the content:
currImageURI = data.getData();
//Save the currImageUri (URI type) to global variable.
photosHolder.getInstance().setOneIm(currImageURI);
}
}
}
Converting the photo
// First Try
File myFile = new File((photosHolder.getInstance().getOneIm()).toString());
params.put("visit_report[photos_attributes][0][file]",myFile); **The exception Raised here
// second try
File myFile2 = new File((photosHolder.getInstance().getOneIm()).getPath());
params.put("visit_report[photos_attributes][1][file]",myFile2); ** Also here
And those are myFiles Value while debuging :
mFile : content:/com.android.providers.media.documents/document/image%3A19143
myFile2 : /document/image:19143
So any help ?
Update
I have tried this solution also :
//get The real path from uri then save it (and then use it to create the file)
photosHolder.getInstance().setUriString(getRealPathFromURI(currImageURI));
//Convert the image URI to the direct file system path of the image file
private String getRealPathFromURI(Uri contentURI) {
String result = "";
try {
Cursor cursor = getActivity().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.DATA);
result = cursor.getString(idx); // Exception raised HERE
cursor.close(); }
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
But I got java.lang.IllegalStateException: Couldn't read row 0, col -1 from CursorWindow. Make sure the Cursor is initialized correctly before accessing data from it and the idx var == to -1
Also I have tried #Praneeth Kalluri Solution but it returns always null as result.
Uri currImageURI = data.getData();
printing currImageURI will give you some thing like this:
content://media/external/images/media/47
But what we need is the absolute path of that particular image . So we need to get real path from uri
public String getRealPathFromURI(Context context, Uri contentUri) {
Cursor cursor = null;
try {
String[] proj = { MediaStore.Images.Media.DATA };
cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} finally {
if (cursor != null) {
cursor.close();
}
}
}
Now modifiy your code like
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK) {
if (requestCode == 1) {
// currImageURI is the global variable I’m using to hold the content:
currImageURI = data.getData();
//Save the currImageUri (URI type) to global variable.
photosHolder.getInstance().setOneIm(getRealPathFromURI(getActivity(),currImageURI));
}
}
}
public String getRealPathFromURI(Context context, Uri contentUri) {
Cursor cursor = null;
try {
String[] proj = { MediaStore.Images.Media.DATA };
cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} finally {
if (cursor != null) {
cursor.close();
}
}
}
I've been trying to get the absolute image path of a image selected in the gallery on KitKat but it doesn't seem to be working out. My variable IMAGE_FILEPATH is always "" after whatever I do. Here's the code for my onActivityResult()
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode != Activity.RESULT_OK) return;
if (null == data) return;
Uri originalUri = null;
if (requestCode == 1) {
//JB!!!
Uri uri = data.getData();
if (uri != null) {
try {
// User had pick an image.
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver()
.query(uri,
filePathColumn, null, null, null);
cursor.moveToFirst();
IMAGE_FILEPATH = cursor.getString(0);
cursor.close();
} catch (Exception e) {
Crouton.makeText(this, "Failed to get image", Style.ALERT).show();
}
}
} else if (requestCode == 2) {
//KK!!!
Uri uri = data.getData();
if (uri != null) {
try {
if( uri == null ) {
IMAGE_FILEPATH = uri.getPath();
} else {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if( cursor != null ){
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
IMAGE_FILEPATH = cursor.getString(column_index);
} else {
IMAGE_FILEPATH = uri.getPath();
}
}
} catch (Exception e) {
Crouton.makeText(this, "Failed to get image", Style.ALERT).show();
}
}
}
Resource.toast(IMAGE_FILEPATH);
super.onActivityResult(requestCode, resultCode, data);
}
What's going wrong? I've tried multiple solutions and nothing seems to work.
In KitKat the Gallery returns an URI like this : content://com.android.providers.media.documents/document/image:1
instead of :
content://media/external/images/media/1
So, here is what you can write under KK to make it works :
if (uri != null) {
try {
if( uri == null ) {
IMAGE_FILEPATH = uri.getPath();
} else {
// get the id of the image selected by the user
String wholeID = DocumentsContract.getDocumentId(data.getData());
String id = wholeID.split(":")[1];
String[] projection = { MediaStore.Images.Media.DATA };
String whereClause = MediaStore.Images.Media._ID + "=?";
Cursor cursor = getContentResolver().query(getUri(), projection, whereClause, new String[]{id}, null);
if( cursor != null ){
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
if (cursor.moveToFirst()) {
IMAGE_FILEPATH = cursor.getString(column_index);
}
cursor.close();
} else {
IMAGE_FILEPATH = uri.getPath();
}
}
} catch (Exception e) {
Crouton.makeText(this, "Failed to get image", Style.ALERT).show();
}
}
And the function I used :
private Uri getUri() {
String state = Environment.getExternalStorageState();
if(!state.equalsIgnoreCase(Environment.MEDIA_MOUNTED)) {
return MediaStore.Images.Media.INTERNAL_CONTENT_URI;
}
return MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
}
These posts helped me : retrieve absolute path when select image from gallery kitkat android and Get real path from URI, Android KitKat new storage access framework
moveToFirst returns a boolean indicating if moving to that position resulted in data.
boolean haveData;
haveData = cursor.moveToFirst();
if (haveData) {
cursor.getString(.....
That's what you should be doing, which is just good, defensive programming. Now, why your cursor is empty, that's going to take more digging to your contentResolver.
I am doing an Android application which need to open camera and display picture on screen and take that picture absolute path.

values.put(MediaStore.Images.Media.TITLE, "ircms");
imgUri = getContentResolver().insert(

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

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:

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
