Android working with MediaStore - android

How can I open a file that I stored in gallery? I used this method to put my file there:
MediaStore.Images.Media.insertImage()
According to documentation it returns String url to the newly created file. However when I trying to open this file it fails. Getting file not found exception.
What am I missing? Any ideas?

It returns the String url or the content uri string back. To get the actual file path from the uri you need to use something like
protected String convertMediaUriToPath(Uri uri) {
String [] proj={MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(uri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String path = cursor.getString(column_index);
cursor.close();
return path;
}
You can convert the string url that you get to the Uri using Uri.parse(url);

How to get path of media files in android

I want paths of files shared through share intent from any app. I do get path of files like zip, apk, pdf, etc. with code ShareCompat.IntentReader.from(this).getStream().getPath();.
But but I don't get path for image, video and audio files I get content://media/external/video/media/40666, How to get real path of files of this type?
If all you want is the path, you can use the following code
public String getRealPathFromURI(Context context, Uri contentUri) {
Cursor cursor = getContentResolver().query(contentUri, null, null, null, null);
cursor.moveToFirst();
String document_id = cursor.getString(0);
document_id = document_id.substring(document_id.lastIndexOf(":")+1);
cursor.close();
cursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,null
, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null);
cursor.moveToFirst();
String path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
cursor.close();
return path;
}
It basically uses he ContentResolver to get the data of the file.
You can change the query parameters to get what you want.
Or you can use
getContentResolver().openInputStream(uri)
If you want the entire file

Get filename and path from URI from mediastore in Nought and Oreo device

I have image uri like this :"content://com.iceburgapp.provider/external_files/.pkgName/File1.jpg"
Now whenever I get path it give me : "/external_files/.pkgName/File1.jpg"
I want to get RealPathFrom content Uri.
I got solution from stackoverflow and I tried below code but not working for me :
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();
}
}
}
AnyOne know How to do this? I got below error for using above code.
java.lang.IllegalArgumentException: column '_data' does not exist. Available columns: []
It's only not working in the Nought and oreo device because of contentUri using file provider.
Use a ContentResolver and openInputStream() to get an InputStream on the content identified by the Uri. Ideally, just use that stream directly, for whatever it is that you are trying to do. Or, use that InputStream and some FileOutputStream on a file that you control to make a copy of the content, then use that file.
This is working properly in devices before Android N

Convert content:// uri into a file path

I am having problems converting a uri to a path because of the content tag. So I am trying to select any file type from the Android storage, and I am able to select a file but when I grab the data and try to convert it to a string path my app crashes.
My code to convert the uri looks like
String path = data.getData().getPath();
I've looked around and some say to use a Content provider and content resolver, but I'm not sure how to use them. Any help would be great thanks.
Display it/ upload it to an s3 bucket. When I mean display it, I mean if it's a photo, or video to show it and if it's an audio file I'd like to be able to play it and the same with other files, like PDF and so on.
This method returns the Path as String
private String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(uri, projection, null, null,null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}

How to get a File from a URI?

I select an image from the image gallery in my app. In the onActivityResult it returns an Intent object and I execute the getData() method on it. I get the image URI back. I am now trying to convert that in to a File so I can send it to AWS S3.
This is what I have been trying but it just returns null:
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = context.getContentResolver().query(contentUri, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = cursor.getString(columnIndex);
cursor.close();
I also try
File file = new File(imageURI.getPath())
also null. Is this impossible or can somebody help?
supposing your onActivityResult checks in with the Intent object being ReturnedIntent you can do
File f = new File(ReturnedIntent.getData());
or get an inputstream and use it
getContentResolver().openInputStream(ReturnedIntent.getData())
//returns inputstream
what is the essence of this String object String filePath ?

Convert real path format to Uri in android

for example
real path is mnt/sdcard/image_1.jpg
Uri path is content://media/external/images/media/140 like this
Uri photoUri =Uri.parse("content://media/external/images/media/140");
Log.d("selectedphoto",""+photoUri);
selectedImagePath = getPath(photoUri);
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
In above code I convert Uri to real path but dnt know how to convert real path to Uri
Try this:
Uri.fromFile(new File("/sdcard/cats.jpg"));
This will get the file path from the MediaProvider, DownloadsProvider, and ExternalStorageProvider, while falling back to the unofficial ContentProvider method you mention.
