Currently I'm trying to retrieve the location of an image in my gallery and convert it into a File so that I can upload it to the internet. But I received this error instead. The error happened when I open the gallery and on selecting the image it crash instead. I'm not so well versed in android and still consider myself a beginner. So if you decided to vote down my question please tell me the reason why so that I can learn. Thank you.

The code that I used to retrieved the image is down below:-
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.DATA);
result = cursor.getString(idx); // getting error here ; it returns -1
cursor.close();
}
return result;
}
You have to add column name MediaStore.Images.Media.DATA with query.
Update getRealPathFromURI() as below:
private String getRealPathFromURI(Uri contentURI) {
String result;
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(contentURI, filePathColumn, 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(filePathColumn[0]);
result = cursor.getString(idx);
cursor.close();
}
return result;
}
In you onActivityResult() method:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
// When an Image is picked
if (requestCode == YOUR_REQUEST_CODE && resultCode == RESULT_OK
&& null != data) {
// Get the Image from data
Uri selectedImage = data.getData();
// Get real path
String imageRealPath = getRealPathFromURI(selectedImage);
// Do something
}
} catch (Exception e) {
Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
.show();
}
}
Make sure you have added permission:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
Here is a good tutorial. Hope this will help~
