File not found error for no apparent reason?

My application should save a piechart as a png on the external storage. However this error appears:
java.io.FileNotFoundException: /storage/emulated/0/SAVE IMAGE EXAMPLE/myimage.png (No such file or directory)
I followed the instructions to add this kind of functionality very closely (From this tutorial), but yet the error appears. The app has the permission to write to external storage, I added the permission in my android_manifest.xml.
Can you guys spot the error? Because i can not.
If you also can't find the error, can you recommend any other way to do this?
Im using MPAndroidChart, but i don't really think it has to do with this, because i could try to save any other object and the error remains.
The code is
final PieChart piechart = (PieChart) findViewById(R.id.piechart);
button2.setOnClickListener(new View.OnClickListener() {
public void onClick (View v) {
Toast.makeText(Main.this, "Chart Saved", Toast.LENGTH_SHORT).show();
piechart.setCenterText("Test");
Bitmap bitmap;
OutputStream output;
bitmap = BitmapFactory.decodeResource(getResources(),R.id.piechart);
File filepath = Environment.getExternalStorageDirectory();
File dir = new File(filepath.getAbsolutePath()+"/SAVE IMAGE EXAMPLE");
dir.mkdirs();
File file = new File(dir, "myimage.png");
try {
output = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, output);
output.flush();
output.close();
}catch(Exception e){
e.printStackTrace();
}
}
});

You need to implement Runtime Permission model to get Storage Permission from user from marshmallow and above.
See the example here for storage permission

android sending files using socket

I am using wifi direct to send file between two android phones.
sender code:
OutputStream outputStream = null;
InputStream inputStream = null;
try {
outputStream = socket.getOutputStream();
inputStream = new FileInputStream(exportTempFile);
byte[] buf = new byte[socket.getSendBufferSize()];
int len = 0;
while ((len = inputStream.read(buf)) != -1) {
outputStream.write(buf, 0, len);
}
outputStream.flush();
return 0;
} catch (IOException e) {
e.printStackTrace();
} finally {
if (socket != null) {
if (socket.isConnected()) {
try {
if (outputStream != null) {
outputStream.close();
}
if (inputStream != null) {
inputStream.close();
}
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
receiver code:
OutputStream outputStream = null;
InputStream inputStream = null;
try {
tempDir = new File(context.getCacheDir(), "temp");
if (!tempDir.exists()) {
tempDir.mkdir();
}
File file = new File(tempDir, "temp.zip");
file.createNewFile();
outputStream = new FileOutputStream(file);
inputStream = socket.getInputStream();
byte[] buf = new byte[socket.getReceiveBufferSize()];
int len = 0;
while ((len = inputStream.read(buf)) != -1) {
outputStream.write(buf, 0, len);
outputStream.flush();
}
return file;
} catch (IOException e) {
e.printStackTrace();
} finally {
if (socket != null) {
if (socket.isConnected()) {
try {
if (outputStream != null) {
outputStream.close();
}
if (inputStream != null) {
inputStream.close();
}
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
However, I always get "W/System.err" at the receiver side when running bytestream.copy . I wonder if I did something wrong. Did I close socket too early so the other side can not get data?

file writing is not performing in android

I need to write the registration credentials into a file during registration and during login will check that file for credentials. but on registration button click nothing is performing.
Manifest file contains this permission:

I'm a newbie to android and java..please help me to find the error.

1) Add android.permission.WRITE_EXTERNAL_STORAGE in AndroidManifest.xml file.
2) Always check for the availability of external storage before writing/reading by :
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
// Can read and write the media
} else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
// Can only read the media
} else {
// Can't read or write
}
3) Create a directory, then make your file in it.
File dir = new File (Environment.getExternalStorageDirectory().getAbsolutePath() + "/myapp");
dir.mkdirs();
File file = new File(dir, "userregister.txt");
NOTE :
If you are using Android 4.4 KitKat, Apps are not allowed to write to secondary external storage devices, except in their package-specific directories
The reason from http://source.android.com/devices/tech/storage/index.html
The WRITE_EXTERNAL_STORAGE permission must only grant write access to the primary external storage on a device. Apps must not be allowed to write to secondary external storage devices, except in their package-specific directories as allowed by synthesized permissions. Restricting writes in this way ensures the system can clean up files when applications are uninstalled.

Button not creating a file and showing email provider option menu when pressed

I've created a button that creates a file then sends it as an attachment to an email,
it grabs the text from one of the textviews, saves it to a .txt and sends it. A small email service option selector should show up too. The code is meant to create a file path if one is not already there. This code is above the onCreate method and in a regular activity.
i keep getting this in the logcat (specific message marked by (-->)):

A few details seem relevant:
First you check the existence of the dir:
File DataDir = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+File.separator+"/LocationData");
if(!DataDir.exists())
{
try
{
DataDir.mkdir();
}
catch (Exception e)
{
e.printStackTrace();
}
}
according to the documentation, your try{}catch(Exception e){} aren't needed. You just would need to check whether the directory actually exists. There's the additional problem that you seem to create a subdirectory of another subdirectory. So, you might want to exchange it to mkdirs() instead.
Afterwards, you try to create the File if it doesn't exist
try {
line 76 ----> Data.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
Take a look at the documentation for this method. You might note that it tells you
This method is not generally useful. For creating temporary files, use
createTempFile(String, String) instead. For reading/writing files, use
FileInputStream, FileOutputStream, or RandomAccessFile, all of which
can create files.
but maybe, if you've included the proper permissions, the changes I suggested above will help to make your code work.

this code keeps coming out with the FileNotFoundException, but the file is there, if you follow the url you can see it.
does it have to be hosted in a specific way? or is it something wrong with the way im getting it
EDIT: this is the logcat message
