I am trying to save an image taken from camera and then storing it on sdCard along with its Thumb also showing this thumb on an imageView.
However it gives error at Null pointer
imageBitmap = Bitmap.createScaledBitmap(imageBitmap, 40, 40, false);
What is wrong?

It's probably because of the decodeStream method.
Bitmap imageBitmap = BitmapFactory.decodeStream(is2, null, options);
You parsed null at the when it asks for a Rectangle and when you tried to create a scaled bitmap it was not valid.
i found my error Bitmap imageBitmap = BitmapFactory.decodeStream(is2, null, options); decoding twice

I currently successfully uploaded an image inside my mobile app to the server.
I am trying to figure out how to resize the image and potentially created a thumbnail before I send this to the server. I have tried many methods I found online but none work.
Below is my code so far.
filePath = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
imageView.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
public void uploadMultipart() {
SessionHandler mySession = new SessionHandler(this);
User user = mySession.getUserDetails();
String title = editText.getText().toString().trim();
String path = getPath(filePath);
String studentid = user.studentid;
String email = user.email;
String firstname = user.firstname;
//Toast.makeText(this, firstname, Toast.LENGTH_SHORT).show();
try {
String uploadId = UUID.randomUUID().toString();
uploadReceiver.setDelegate(this);
uploadReceiver.setUploadID(uploadId);
new MultipartUploadRequest(this, uploadId, Constants.UPLOAD_URL)
.addFileToUpload(path, "image")
.addParameter("title", title)
.addParameter("studentid", studentid)
.addParameter("firstname", firstname)
.addParameter("email", email)
//.setNotificationConfig(new UploadNotificationConfig())
.setMaxRetries(2)
.startUpload();
} catch (Exception exc) {
Toast.makeText(this, exc.getMessage(), Toast.LENGTH_SHORT).show();
}
}
To compress your image write this method on your activity
public void compressImage(String filePath) {
try {
OutputStream outStream = null;
Log.i("filePath",filePath);
outStream = new FileOutputStream(filePath);
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bmOptions.inSampleSize = 8;
bitmap = BitmapFactory.decodeFile(filePath ,bmOptions);
bitmap.compress(Bitmap.CompressFormat.JPEG, 50, outStream);
outStream.flush();
outStream.close();
Log.i("file path compress", filePath);
} catch (Exception e) {
Log.i("exception", e.toString());
}
}
and call it in your on activity result
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == TAKE_PHOTO){ //your request code
filePath = data.getData();
try {
compressImage(filePath);
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
imageView.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
}
You can compress your image as much as you want on the compressImage method.
public Bitmap resizeBitmap(Bitmap bitmap, int newWidth, int newHeight) {
int width = bitmap.getWidth();
int height = bitmap.getHeight();
float scaleWidth = ((float) newWidth) / width;
float scaleHeight = ((float) newHeight) / height;
Matrix matrix = new Matrix();
matrix.postScale(scaleWidth, scaleHeight);
Bitmap resizedBitmap = Bitmap.createBitmap(
bitmap, 0, 0, width, height, matrix, false);
bitmap.recycle();
return resizedBitmap;
}
I have an issue with my code. When I take a photo from my app, it is rotating 90ยบ to show. But, when I choose gallery option to select my photo, it is showing normal.
Can someone help me??
Code bellow:
Adapter.java
public void onBindViewHolder(#NonNull final ProdutosListaViewHolder holder, final int i){
Produto prod = produtos.get(i);
File foto = mPicture.getImageProduto(prod.codProd);
if(foto == null || foto.exists()){
holder.foto.setImageResource(R.drawable.sem_foto_icon);
}else{
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.RGB_565;
Bitmap bitmap = BitmapFactory.decodeFile(foto.getAbsolutePath(), options);
holder.foto.setImageBitmap(bitmap);
}
}
PictureManager.java
if the camera selected to take the photo
Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
i.putExtra(MediaStore.EXTRA_OUTPUT, FileProvider.getUriForFile(ctx, ....));
((Activity) ctx).startActivityForResult(i, 999);
if the gallery selected to take the photo
Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
((Activity) ctx).startActivityForResult(i, 998);

if(foto != null){

}
}catch(Exception e){
e.printStackTrace();
}
}else if(requestCode==998){
try{
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };

int codigo = produtoSelecionado.codProd;
File foto = (new PictureManager(FOTO_PRODUTO, ctx)).salvarFoto(file, codigo, 1);

}
}
}
}
}
Camera always gives you the picture according to camera orientation. I have tried the below code to change orientation
public static Bitmap rotateImageOrientation(String photoFilePath) {
// Create and configure BitmapFactory
BitmapFactory.Options bounds = new BitmapFactory.Options();
bounds.inJustDecodeBounds = true;
BitmapFactory.decodeFile(photoFilePath, bounds);
BitmapFactory.Options opts = new BitmapFactory.Options();
Bitmap bm = BitmapFactory.decodeFile(photoFilePath, opts);
// Read EXIF Data
ExifInterface exif = null;
try {
exif = new ExifInterface(photoFilePath);
} catch (IOException e) {
e.printStackTrace();
}
String orientString = exif.getAttribute(ExifInterface.TAG_ORIENTATION);
int orientation = orientString != null ? Integer.parseInt(orientString) : ExifInterface.ORIENTATION_NORMAL;
int rotationAngle = 0;
if (orientation == ExifInterface.ORIENTATION_ROTATE_90) rotationAngle = 90;
if (orientation == ExifInterface.ORIENTATION_ROTATE_180) rotationAngle = 180;
if (orientation == ExifInterface.ORIENTATION_ROTATE_270) rotationAngle = 270;
// Rotate Bitmap
Matrix matrix = new Matrix();
matrix.setRotate(rotationAngle, (float) bm.getWidth() / 2, (float) bm.getHeight() / 2);
return Bitmap.createBitmap(bm, 0, 0, bounds.outWidth, bounds.outHeight, matrix, true);
// Return result
}
I am trying to get an image from gallery or take one using camera in android. taking one using camera app works so fine but getting an image from gallery returs a nullpointer when compressing. below shows my code for sellecting from gallery and camera

image_String = SessionManager.encodeTobase64(bm);
Log.d("bm", image_String.toString());
profile_pic.setImageBitmap(bm);
}
}
}
and here is my mothhod to perform the encoding of the imgage i just got
public static String encodeTobase64(Bitmap img){
Bitmap image = img;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
image.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] b = baos.toByteArray();

return imageEncoded;
}
can't figure out the encode method signals an error when compresing the bitmap taken from gallery of device. Please help me out

To improve the image quality you should change compression to PNG, or change the second parameters to 100 (PNG is lossless and will ignore second params).
b.compress(Bitmap.CompressFormat.PNG, 100, out);
To change external into internal just change
File outputFile = new File(Environment.getExternalStorageDirectory(), "photo_" + currentDate + ".jpg");
into
File outputFile = new File(context.getFilesDir(), "photo_" + currentDate + ".jpg");
The image you are trying to save returns you jest the thumbnail of the actual image that is why you are getting low quality image. You should pass the image name to the intent to save the high quality image when it is captured
Following Helper class that I use for image capture may be of some help to you

After follow the tutorial, I have changed my code to

matrix.setRotate(rotationAngle, (float) bm.getWidth() / 2, (float) bm.getHeight() / 2);
Bitmap rotatedBitmap = Bitmap.createBitmap(bm, 0, 0, bitmapOptions.outWidth, bitmapOptions.outHeight, matrix, true);
Global.img = bitmap;
b.setImageBitmap(bitmap);
String path = android.os.Environment
.getExternalStorageDirectory()
+ File.separator
+ "Phoenix" + File.separator + "default";
//p = path;
f.delete();
OutputStream outFile = null;
File file = new File(path, String.valueOf(System.currentTimeMillis()) + ".jpg");
setRotate in matrix.setRotate cannot be solved.
I get a red line underneath (bm, 0, 0, bitmapOptions.outWidth, bitmapOptions.outHeight, matrix, true); (cannot resolved method createBitmap )

I guess you imported the wrong Matrix class, you should import android.graphics.Matrix, not android.opengl.Matrix, please double check.
