how can I upload a photo from the gallery to parse.com?

I am trying to upload a photo from the gallery into my parse cloud but I can't figure it out here's my code and what I've done so far .
I've looked everywhere still can't find a solution , can't upload the photo :\
help me please.
public void loadImagefromGallery(View view) {
// Create intent to Open Image applications like Gallery, Google Photos
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
// Start the Intent
startActivityForResult(galleryIntent, RESULT_LOAD_IMG);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
// When an Image is picked
if (requestCode == RESULT_LOAD_IMG && resultCode == RESULT_OK
&& null != data) {
// Get the Image from data
Uri selectedImage = data.getData();
myBitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImage);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
myBitmap.compress(Bitmap.CompressFormat.JPEG, 100, bos);
byte[] scaledData = bos.toByteArray();
photoFile = new ParseFile("my_photo.jpg", scaledData);
photoFile.saveInBackground(new SaveCallback() {
public void done(ParseException e) {
if (e != null) {
Toast.makeText(getApplicationContext(),
"Error saving: " + e.getMessage(),
Toast.LENGTH_LONG).show();
} else {
// do something
}
}
});

Save ParseObject in the background
// Create the ParseFile
ParseFile file = new ParseFile("androidbegin.png", image);
// Upload the image into Parse Cloud
file.saveInBackground();
// ParseObject
ParseObject pObject = new ParseObject("ExampleObject");
// Create a column named "ImageName" and set the string
pObject.put("ImageName", "image name here");
// Create a column named "ImageFile" and insert the image
pObject.put("ImageFile", file);
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;
}
}
});

android finish sometimes restarting app

I'm working on an app which allows user to choose a picture from gallery and then I start a activity to crop it.
I want to send the cropped image back to calling activity.
Both activities extend AppCompatActivity.
Calling activity:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
// start image crop activity
String dataString = data.getDataString();
Intent intent=new Intent(this, CropPhotoActivity.class);
intent.putExtra("SELECTED_PICTURE_FOR_CROP", dataString);
startActivityForResult(intent, CROP_PICTURE);
}
else if(requestCode == CROP_PICTURE) {
// get cropped bitmap
Bitmap bitmap = (Bitmap) data.getParcelableExtra("CROPPED_IMAGE");
profilePhoto.setImageBitmap(bitmap);
}
}
}
In the crop image activity, I have a button, which on click should return back to calling activity:
Button okButton = (Button)findViewById(R.id.ok_button);
okButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent returnIntent = new Intent();
returnIntent.putExtra("CROPPED_IMAGE", cropped_bitmap);
setResult(RESULT_OK, returnIntent);
finish(); // sometimes restarts app
}
});
Sometimes the bitmap gets returned correctly whereas sometimes it does not and the app gets restarted without error. Why is this happening? Does putExtra have anything to do with bitmap size or anything else?

You could try substituting
AppcompatActivity.this.finish()
(where AppcompatActivity is your class name)
for:
finish(); // sometimes restarts app
Or, create a method in the calling Activity:
public static void cropComplete(Activity activity)
{
activity.startActivity(activity, AnotherActivity.class);
activity.finish();
}

Theres's a limit for data length passed as extra in a intent. Try not passing the dataString value; instead you should save the image as a temporary file, pass the path in the intent and then load the image from your calling activity (or you can just save the dataString in a static helper class).
In the crop activity (saving bitmap code from Save bitmap to location):
// Save bitmap
String filename = "tempImage.png";
File sd = Environment.getExternalStorageDirectory();
File dest = new File(sd, filename);
FileOutputStream out = null;
try {
out = new FileOutputStream(dest);
bmp.compress(Bitmap.CompressFormat.PNG, 100, out); // bmp is your Bitmap instance
// PNG is a lossless format, the compression factor (100) is ignored
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (out != null)out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
// Get image file path
String path = dest.getAbsolutePath();
// Set result with image path
Intent returnIntent = new Intent();
returnIntent.putExtra("CROPPED_IMAGE_PATH", path);
setResult(RESULT_OK, returnIntent);
finish();
In the caller activity:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if(requestCode == CROP_PICTURE) {
// Get image file path
String imagePath = data.getStringExtra("CROPPED_IMAGE_PATH");
// Load image
Bitmap bitmap = BitmapFactory.decodeFile(imagePath);
}
}

Upload image to server from gallary or camera android

i have a Activity for Upload image from gallary or camera to server.image upload from camera is fine but upload from gallary is not done.i have a error showing
BitmapFactory﹕ Unable to decode stream: FileNotFoundException
i want to do when i pick up the image from gallary it is shown in other Activity on image view.
i don't know how to get fileuri for gallary please help me.
my code:
loadimage = (ImageView) findViewById(R.id.profilpic);
loadimage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
/* Intent i = new Intent(Tab1.this, ImageMain.class);
startActivity(i);*/
// selectImageFromGallery();
AlertDialog.Builder builder = new AlertDialog.Builder(Tab1.this);
builder.setMessage("Select Image From")
.setCancelable(true)
.setPositiveButton("camera", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
// start the image capture Intent
startActivityForResult(intent, CAMERA_REQUEST);
}
})
.setNegativeButton("gallary", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, RESULT_LOAD_IMAGE);
}
});
AlertDialog alert = builder.create();
alert.show();
}
});
Hear is my onActiivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// if the result is capturing Image
if (requestCode == CAMERA_REQUEST) {
if (resultCode == RESULT_OK) {
launchUploadActivity(true);
} else if (resultCode == RESULT_CANCELED) {
// user cancelled Image capture
Toast.makeText(getApplicationContext(),
"User cancelled image capture", Toast.LENGTH_SHORT)
.show();
} else {
// failed to capture image
Toast.makeText(getApplicationContext(),
"Sorry! Failed to capture image", Toast.LENGTH_SHORT)
.show();
}
}
else if(requestCode==RESULT_LOAD_IMAGE){
if (resultCode==RESULT_OK){
launchUploadActivity(true);
}
}
}
private void launchUploadActivity(boolean isImage){
Intent i = new Intent(Tab1.this,UploadAvtivity.class);
i.putExtra("filePath", fileUri.getPath());
i.putExtra("isImage", isImage);
startActivity(i);
}

Here is the Code piece for Taking a Picture through Default Camera (here I implemented Intent to to fetch the image). After that store it to SD card(here a new file will be created and the newly taken image will be stored ); and if you don't want to store then remove the saving part from code. After that you can use the file path for your upload purpose. You can then refer it and change to get the path as your wish.
In the class area put these lines
final int TAKE_PHOTO_REQ = 100;
String file_path = Environment.getExternalStorageDirectory()
+ "/recent.jpg";//Here recent.jpg is your image name which will going to take
After that invoke the camera by putting these line in calling method.
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, TAKE_PHOTO_REQ);
then add this method in your Activity to get the picture and save it to sd card and you can invoke your upload method from here to upload the image by knowing its path.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case TAKE_PHOTO_REQ: {
if (resultCode == TakePicture.RESULT_OK && data != null) {
Bitmap srcBmp = (Bitmap) data.getExtras().get("data");
// ... (process image if necesary)
imageView.setImageBitmap(srcBmp);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
srcBmp.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
// you can create a new file name "test.jpg" in sdcard folder.
File f = new File(file_path);
try {
f.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// write the bytes in file
FileOutputStream fo = null;
try {
fo = new FileOutputStream(f);
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
fo.write(bytes.toByteArray());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// remember close de FileOutput
try {
fo.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.e("take-img", "Image Saved to sd card...");
// Toast.makeText(getApplicationContext(),
// "Image Saved to sd card...", Toast.LENGTH_SHORT).show();
break;
}
}
}
}
Hope this will be helpful for you and others too .. thanks

Populating listview from sdcard images

I would like to add images from my sdcard to my listview. Currently I can choose picture from my sdcard by the button click on my UI. The implementation to choose picture is this:
sendPicture.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mybyte=null;
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),1);
}
});
The onActivityResult of this implementation is:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
currImageURI = data.getData();
myvariable=getRealPathFromURI(currImageURI);
try {
mybyte=fileToByteArray(myvariable);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
My aim is convert "mybyte", which is a byte[] variable, to an image and put the image on my listview.
Any help is appreciated.

With such an implimentation,transforming byte[] to Bitmap and store Bitmaps in your adapter source list, you will get an OutOfMemmory error. Will be better to store in your ArrayList not the Bitmap but the path to it, you get it from cursor after chosing bitmap from galery, and load the Bitmap in an AsyncTask in the getView method of your CustomAdapter.Google has a good example on how to do a fancy ListView with ImageViews HERE

why my file type is not supporting to send taken picture as MMS
