How to upload an image in parse server using parse api in android

I want to upload an image in parse cloud server in android. But I am unable to do so.

I have tried the following code:

Drawable drawable = getResources().getDrawable(R.drawable.profilepic) ;
Bitmap bitmap = (Bitmap)(Bitmap)drawable()
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] data = stream.toByteArray();                

ParseFile imageFile = new ParseFile("image.png", data);
imageFile.saveInBackground();

Please let me know how can I do it.

After struggling for several hours here is code segment works for me.

1. Data Member of activity class

Bitmap bmp;
Intent i;
Uri BmpFileName = null;

2. Starting the camera. Goal is to start camera activity and BmpFileName to store the referrence to file

String storageState = Environment.getExternalStorageState();
if (storageState.equals(Environment.MEDIA_MOUNTED)) {

String path = Environment.getExternalStorageDirectory().getName() + File.separatorChar + "Android/data/" + this.getPackageName() + "/files/" + "Doc1" + ".jpg";

File photoFile = new File(path);
try {
if (photoFile.exists() == false) { 
photoFile.getParentFile().mkdirs();
photoFile.createNewFile();
}
} 
catch (IOException e) 
{
Log.e("DocumentActivity", "Could not create file.", e);
}
Log.i("DocumentActivity", path);
BmpFileName = Uri.fromFile(photoFile);
i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, BmpFileName);
startActivityForResult(i, 0);

3. Reading contents from Camera output by overriding onActivityResult. Goal is to get bmp variable valuated.

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
try {
bmp = MediaStore.Images.Media.getBitmap( this.getContentResolver(), BmpFileName);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {

// TODO Auto-generated catch block
e.printStackTrace();
}
// Myocode to display image on UI - You can ignore
if (bmp != null)
IV.setImageBitmap(bmp);
}
}

4. On Save event

// MUST ENSURE THAT YOU INITIALIZE PARSE
Parse.initialize(mContext, "Key1", "Key2");

ParseObject pObj = null;
ParseFile pFile = null ;
pObj = new ParseObject ("Document");
pObj.put("Notes", "Some Value");

// Ensure bmp has value
if (bmp == null || BmpFileName == null) {
Log.d ("Error" , "Problem with image"
return;
}

ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(CompressFormat.PNG, 100, stream);
pFile = new ParseFile("DocImage.jpg", stream.toByteArray());
try 
{
pFile.save();
pObj.put("FileName", pFile);
pObj.save();
_mParse.DisplayMessage("Image Saved");
} 
catch (ParseException e) 
{
// TODO Auto-generated catch block
_mParse.DisplayMessage("Error in saving image");
e.printStackTrace();
}

// Finish activity in my case . you may choose some thing else finish();

So here are key difference from others

  • I called initialize parse. You may laugh about it but folks have spent hour's debugging code without realize that parse was not initialized
  • Use Save instead of SaveInBackground. I understand that it may hold the activity but that is desired behavior for me and more importantly it works

Let me know if it does not work

Save ParseObject in the background

// ParseObject
  ParseObject pObject = new ParseObject("ExampleObject");
  pObject.put("myNumber", number);
  pObject.put("myString", name);
  pObject.saveInBackground(); // asynchronous, no callback

Save in the background with callback

pObject.saveInBackground(new SaveCallback () {
   @Override
   public void done(ParseException ex) {
    if (ex == null) {
        isSaved = true;
    } else {
        // Failed
        isSaved = false;
    }
  }
});

Variations of the save...() method include the following:

    saveAllinBackground() saves a ParseObject with or without a callback.
    saveAll(List<ParseObject> objects) saves a list of ParseObjects.
    saveAllinBackground(List<ParseObject> objects) saves a list of ParseObjects in the 
    background.
    saveEventually() lets you save a data object to the server at some point in the future; use 
    this method if the Parse cloud is not currently accessible.

Once a ParseObject has been successfully saved on the Cloud, it is assigned a unique Object-ID. This Object-ID is very important as it uniquely identifies that ParseObject instance. You would use the Object-ID, for example, to determine if the object was successfully saved on the cloud, for retrieving and refreshing a given Parse object instance, and for deleting a particular ParseObject.

I hope you will solve your problem..

Parse.initialize(this, "applicationId", "clientKey");

     byte[] data = "Sample".getBytes();    //data of your image file comes here

     final ParseFile file = new ParseFile(data);
     try {

Use it like this

 //Convert Bitmap to Byte array --For Saving Image to Parse Db. */

 Bitmap profileImage= "your bitmap";

 ByteArrayOutputStream blob = new ByteArrayOutputStream();

 profileImage.compress(CompressFormat.PNG, 0 /* ignored for PNG */,blob);

 imgArray = blob.toByteArray();

 //Assign Byte array to ParseFile
 parseImagefile = new ParseFile("profile_pic.png", imgArray);

 parseUser.getCurrentUser().put("columname in parse db", parseImagefile);
 parseUser.getCurrentUser().saveInBackground();

I hope this will help you..
