I can load the picture to the background then I have also been able to "sketchify" it but when I try to save it so that I can email it as an attachment I can only figure out haw to grab the original image and what I have here makes the activity close
public void startCamera(View v) {
Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
seek.setVisibility(View.GONE);
if (takePicture.resolveActivity(getPackageManager()) != null) {
picSpot = new File(Environment.getExternalStorageDirectory(),
"sketch.png");
outputFileUri = Uri.fromFile(picSpot);
takePicture.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(takePicture, REQUEST_IMAGE_CAPTURE);
}
}
public void sendPic(View v) {
Intent sharePic = new Intent(Intent.ACTION_SEND);
if (didsketch == false) {
sharePic.setType("image/png");
sharePic.putExtra(Intent.EXTRA_STREAM, outputFileUri);
sharePic.putExtra(Intent.EXTRA_SUBJECT, "Check This Out!");
sharePic.putExtra(Intent.EXTRA_TEXT,

startActivity(Intent.createChooser(sharePic, "Send Email"));
} else {
try {

back.compress(Bitmap.CompressFormat.PNG, 90, out);

back is the modified bitmap i am trying to eventually attach to the email
Thanks!!!
Create Folder Directory and Save image into it: create directory where you want to save your images. Suppose the folder name is ImageFolder.
String location = Environment.getExternalStorageDirectory() + "/ImageFolder/";
//Creating Folder Directory
File imageDir = new File(location);
dir.mkdirs();
//Creating Image file
String imageName = "sketch.png";
File imageFile = new File(imageDir, imageName);
//If image file already exists then delete it.
if (imageFile.exists()) {
imageFile.delete();
}
//Writing the image to SDCard
try {
FileOutputStream out = new FileOutputStream(imageFile);
back.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}

I checked storage permission, but storage permission have no problem.
Can anyone help me out..?
So the app I have, takes a photograph (or uses from library) and brings the captured photo into an editing view. The code for the camera capture is;
public void cameraClicked(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 2);
}
The camera view opens, allows me to take a photo, but when it moves to EditorActivity.class the photo is not there, just a black screen. The editor view is fine, but it does not seem to be taking what I capture with the camera. I have set the correct permissions, this works fine in versions prior to Level 23
SDK version.
Edit - updated code methods below;
boolean SaveImage(Bitmap finalBitmap) {
String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
Random generator = new Random();

n = generator.nextInt(n);
String fname = "Image-" + n + ".jpg";
File file = new File(myDir, fname);
if (file.exists())
file.delete();
try {

First of All make sure you have declared the "Access External Storage" and "Access Hardware Camera" permissions in "AndroidManifest" and if you are using Android version 23 or 23+ then you have to take permissions on run-time.
If this is not the problem then use this code given below, it's working fine for me.
For Camera:
Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, ACTION_REQUEST_CAMERA);
For Gallery:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
Intent chooser = Intent.createChooser(intent, "Choose a Picture");
startActivityForResult(chooser, ACTION_REQUEST_GALLERY);
OnActivityResultMethod:
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
switch (requestCode) {
case ACTION_REQUEST_GALLERY:
Uri galleryImageUri = data.getData();
try{
Log.e("Image Path Gallery" , getPath(getActivity() , galleryImageUri));
selectedImagePath = getPath(getActivity() , galleryImageUri);
} catch (Exception ex){
ex.printStackTrace();
Log.e("Image Path Gallery" , galleryImageUri.getPath());
selectedImagePath = galleryImageUri.getPath();
}
break;
case ACTION_REQUEST_CAMERA:
// Uri cameraImageUri = initialURI;
Uri cameraImageUri = data.getData();
Log.e("Image Path Camera" , getPath(cameraImageUri));
selectedImagePath = getPath(cameraImageUri);
break;
}
}
}
Method to get path of Image returned from Camera:
/**
* helper to retrieve the path of an image URI
*/
public String getPath(Uri uri) {
// just some safety built in
if( uri == null ) {
// TODO perform some logging or show user feedback
return null;
}
// try to retrieve the image from the media store first
// this will only work for images selected from gallery
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = getActivity().managedQuery(uri, projection, null, null, null);
if( cursor != null ){
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
// this is our fallback here
return uri.getPath();
}
I've written a method that creates a directory in my apps cache directory and then prompts the user to take a photo or select a photo from the gallery.
if the user takes a new photo, the photo is saved to the cache as profile.jpg
I'm trying to get the intent that returns a photo from the gallery to save the returned photo in the cache directory of my app as profile.jpg.
I'm having trouble achieving this.
public void selectImage(View v) {
File newDir = new File(getExternalCacheDir(), "RecruitSwift");
if(!newDir.isDirectory())
newDir.mkdirs();
else
Toast.makeText(this, "Dir already exist", Toast.LENGTH_LONG).show();
if(newDir.canWrite())
imageFile = new File(newDir, "profile.jpg");
else
Toast.makeText(this, "Dir not writable", Toast.LENGTH_LONG).show();
final CharSequence[] options = { "Take Photo", "Choose from Gallery","Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(UserProfileInterviewScreenActivity.this);
builder.setTitle("Add Photo!");
builder.setItems(options, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("Take Photo")){
Intent takeProfileImage = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takeProfileImage.resolveActivity(getPackageManager()) != null) {
Uri imageUri = Uri.fromFile(imageFile);
takeProfileImage.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(takeProfileImage, 1);
}
}
else if (options[item].equals("Choose from Gallery")){
Intent takeProfileImage = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
Uri selectedImage = takeProfileImage.getData();
imageFile = selectedImage;
startActivityForResult(takeProfileImage, 2);
}
else if (options[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}
If you want to take a photo or pick a picture, you need to call startActivityForResult and then override onActivityResult. Here are some codes to take a photo, take a look:
startActivityForResult:
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
intent.putExtra("return-data", false);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(AVATAR_FILE_TMP));
intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
intent.putExtra("noFaceDetection", true);
startActivityForResult(intent, CODE_TAKE_PHOTO);
then override onActivityResult:
if (resultCode == Activity.RESULT_OK) {
if (requestCode == CODE_TAKE_PHOTO) {
cropImage(Uri.fromFile(AVATAR_FILE_TMP));
}
}
As pointed out by #greenapps the intent it's self doesn't return anything, you have to get the returned content provider path in your onActivityResult method and convert it into a file system path.
This is the code I wrote in the end:
Uri selectedImage = data.getData();
String[] filePath = { MediaStore.Images.Media.DATA };
Cursor c = getContentResolver().query(selectedImage,filePath, null, null, null);
c.moveToFirst();
int columnIndex = c.getColumnIndex(filePath[0]);
String picturePath = c.getString(columnIndex);
c.close();
Bitmap thumbnail = (BitmapFactory.decodeFile(picturePath));
Log.w("path of profileImage.setImageBitmap(thumbnail);
try{
String file_path = getExternalCacheDir() + "/MyWebsiteDir";
File dir = new File(file_path);
if(!dir.exists())
dir.mkdirs();
File file = new File(dir, "profile.jpg");
FileOutputStream fOut = new FileOutputStream(file);
thumbnail.compress(Bitmap.CompressFormat.PNG, 85, fOut);
fOut.flush();
fOut.close();
}
catch (Exception e) {
e.printStackTrace();
}
When I take a picture with my device, this code is crashing on the inputStream = line with an error of java.lang.NullPointerException
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Uri uriImage;
InputStream inputStream = null;
ImageView imvCover = (ImageView)this.findViewById(R.id.imvCover);
if ((requestCode == CAPTURE_IMAGE) && resultCode == Activity.RESULT_OK) {
uriImage = data.getData();
try {
inputStream = getContentResolver().openInputStream(uriImage);
Bitmap bitmap = BitmapFactory.decodeStream(inputStream, null, null);
imvCover.setImageBitmap(bitmap);
} catch (NullPointerException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
imvCover.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
imvCover.setAdjustViewBounds(true);
}
}
Any ideas why?
This is the code I am using to open the camera to take a picture:
Button btnTakePicture = (Button)this.findViewById(R.id.btnTakePicture);
btnTakePicture.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAPTURE_IMAGE);
}
});
try this..
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File out = Environment.getExternalStorageDirectory();
out = new File(out, "newImage.jpg");
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(out));
startActivityForResult(i, 1);
and this is onActivity result..
#Override
protected void onActivityResult(int requestCode, int resultcode, Intent intent)
{
super.onActivityResult(requestCode, resultcode, intent);
File out = new File(Environment.getExternalStorageDirectory(), "newImage.jpg");
if(!out.exists())
{
Log.v("log", "file not found");
Toast.makeText(getBaseContext(),
"Error while capturing image", Toast.LENGTH_LONG)
.show();
return;
}
Log.v("log", "file "+out.getAbsolutePath());
File f = new File(out.getAbsolutePath());
try {
ExifInterface exif = new ExifInterface(out.getAbsolutePath());
orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);
//Toast.makeText(getApplicationContext(), ""+orientation, 1).show();
Log.v("log", "ort is "+orientation);
} catch (IOException e)
{
e.printStackTrace();
}
Bitmap photo =decodeFile(f,400,400);
}
and this is decodeFile Function...
public static Bitmap decodeFile(File f,int WIDTH,int HIGHT){
try {
//Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(new FileInputStream(f),null,o);
//The new size we want to scale to
final int REQUIRED_WIDTH=WIDTH;
final int REQUIRED_HIGHT=HIGHT;
//Find the correct scale value. It should be the power of 2.
int scale=1;
while(o.outWidth/scale/2>=REQUIRED_WIDTH && o.outHeight/scale/2>=REQUIRED_HIGHT)
scale*=2;
//Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize=scale;
return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
} catch (FileNotFoundException e) {}
return null;
}
This approach may not work for all devices. Instead, you can specify where the new image would be saved, and then you can use that pre-determined file path to work with the new image.
File tempFolder = new File(Environment.getExternalStorageDirectory().getAbsolutePath()
+ "/your_folder");
tempFolder.mkdir();
file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()
+ "/your_folder", String.valueOf(System.currentTimeMillis()) + ".jpg");
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
startActivityForResult(intent, TAKE_PICTURE);
