I'm trying to upload a image to php, for that I need to send a File to the server. So I am trying to create a file from the data parameter.
But I got this error Cannot resolve constructor File
Here's my code:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
// Get the url from data
Uri selectedImageUri = data.getData();
if (null != selectedImageUri) {
// File
File imageFilePath = new File(selectedImageUri);
You can try this;
try {
Uri uri = data.getData();
String selectedFilePath = FilePath.getPath(getActivity(), uri);
final File file = new File(selectedFilePath);
new UploadFileToServer().execute(file);
}
catch (Exception e)
{
e.printStackTrace();
}
and define FilePath
class like this;

The appropriate way is to getContentResolver().openInputStream(uri_of_your_file);
and using a FileOutputStream
to your desired path and then use that file.
As from Commonsware answer
You can use ContentResolver and openInputStream() to get an InputStream on the content represented by the Uri. You can create a FileOutputStream on some file that you control. And, you can use Java I/O to copy from the InputStream to the OutputStream, making your own copy of the content in a file that you control.
Sample code for doing that,
InputStream in = getContentResolver().openInputStream("your_uri_here");
OutputStream out = new FileOutputStream(new File("your_file_here"));
byte[] buf = new byte[1024];
int len;
while((len=in.read(buf))>0){
out.write(buf,0,len);
}
out.close();
in.close();
