How to create folder in internal storage and save captured image

I want to capture image and save it to specific folder in internal storage. Currently i am able to open intent and get thumbnail of captured image. I dont want to user extrnal stotage as now mostly users use their internal storage and not sd card.
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (intent.resolveActivity(getPackageManager()) != null){
startActivityForResult(intent,1);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
if (requestCode == 1 && resultCode == RESULT_OK){
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
LayoutInflater inflater = LayoutInflater.from(LeaveApplicationCreate.this);
final View view = inflater.inflate(R.layout.item_image,attachView, false);
ImageView img = view.findViewById(R.id.img);
AppCompatImageView btnRemove = view.findViewById(R.id.btnRemove);
img.setImageBitmap(imageBitmap);
btnRemove.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
attachView.removeView(view);
}
});
attachView.addView(view);
File directory = new File(Environment.getExternalStorageDirectory(),"/Digimkey/Camera/");
if (!directory.exists()) {
directory.mkdir();
}
File file = new File(directory, System.currentTimeMillis()+".jpg");
try (FileOutputStream out =new FileOutputStream(file)) {
imageBitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
} catch (IOException e) {
e.printStackTrace();
}
}
}

First gain Write Permissions.
File directory = new File(Environment.getExternalStorageDirectory(), dirName);
if (!directory.exists()) {
directory.mkdirs();
}
File file = new File(directory, fileName);
if (!file.exists()) {
file.createNewFile();
}
try (FileOutputStream out =new FileOutputStream(file)) {
bmp.compress(Bitmap.CompressFormat.PNG, 100, out);
} catch (IOException e) {
e.printStackTrace();
}
There are two types of storage.
1) Internal ex. "/root/.."
Unless you have rooted device, we can't access. this path.
2) External ex. "/storage/emuated/0"
Environment.getExternalStorageDirectory()
By using this path, we are able to create a directory/file.

Use to method to save your bimap in local storage. Pass bimap image as parameter i.e saveToInternalStorage(imageBitmap)
private String saveToInternalStorage(Bitmap bitmapImage){
//set image saved path
File storageDir = new File(Environment.getExternalStorageDirectory()
+ "MyApp"+ "/Files");
if (!storageDir.exists()) {
storageDir.mkdirs();
}
File mypath=new File(storageDir,"bitmap_image.jpg");
FileOutputStream fos = null;
try {
fos = new FileOutputStream(mypath);
bitmapImage.compress(Bitmap.CompressFormat.PNG, 100, fos);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return directory.getAbsolutePath();
}
Required permissions in Manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Android - How to store and retrieve the image from internal storage

I want to take image from camera and store it and view it from internal storage.
I use this code to take image from camera.
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, TAKE_PIC);
I tried the following to save the bitmap in internal storage.
public String saveToInternalSorage(Bitmap bitmapImage, String fileName){
File file = new File(createBasePath(), fileName + ".png");
FileOutputStream fos = null;
try {
fos = new FileOutputStream(file);
bitmapImage.compress(Bitmap.CompressFormat.PNG, 100, fos);
fos.close();
} catch (Exception e) {
e.printStackTrace();
}
return file.getName();
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == TAKE_PIC && resultCode == RESULT_OK) {
Intent i=new Intent(Intent.ACTION_VIEW);
i.setDataAndType(Uri.fromFile(output), "image/png");
startActivity(i);
}
}
My path is /data/user/0/com.dev/app/1454351400000/33352/capture_Image1.png
But here I am facing one issue. The bit map size is very small. I want exact image what I taken from camera.
Then I found one solution. Set the path before intent. So I tried like this.
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
output = new File(createBasePath(), "capture_Image1" + ".png");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(output));
startActivityForResult(intent, TAKE_PIC);
When I use this code the image is not showing. on onActivityResult the resultCode showing -1.
If I use the following code
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File dir= Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
output=new File(dir, "CameraContentDemo.png");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(output));
startActivityForResult(intent, TAKE_PIC);
This code is working fine. After taking the image it showing image.
So please let me know store and retrieve the image from internal db with original quality.

Below is code to save the image to internal directory.
private String saveToInternalStorage(Bitmap bitmapImage){
ContextWrapper cw = new ContextWrapper(getApplicationContext());
// path to imageDir
File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);
// Now Create imageDir
File mypath=new File(directory,"abc.jpg");
FileOutputStream foss = null;
try {
foss = new FileOutputStream(mypath);
// Using compress method on the BitMap object to write image to the OutputStream
bitmapImage.compress(Bitmap.CompressFormat.PNG, 100, foss);
} catch (Exception e) {
e.printStackTrace();
} finally {
foss.close();
}
return directory.getAbsolutePath();
}
Use below code for Reading a file from internal storage
private void loadImageFromStorage(String path)
{
try {
File f=new File(path, "abc.jpg");
Bitmap b = BitmapFactory.decodeStream(new FileInputStream(f));
ImageView img=(ImageView)findViewById(R.id.imgPicker);
img.setImageBitmap(b);
}
catch (FileNotFoundException e)
{
e.printStackTrace();
}
}

void openMultiSelectGallery() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri =getOutputMediaFile();
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
/* start activity for result pass intent as argument and request code */
startActivityForResult(intent, CAMERA_REQUEEST_CODE);
}
/**
* This method set the path for the captured image from camera for updating
* the profile pic
*/
private Uri getOutputMediaFile() {
File mediaStorageDir = new File(
Environment.getExternalStorageDirectory(), "."
+ Constants.CONTAINER);
// Create the storage directory if it does not exist
if (!mediaStorageDir.exists()) {
mediaStorageDir.mkdirs();
}
File mediaFile = new File(mediaStorageDir.getPath() + File.separator
+ "IMG_" + System.currentTimeMillis() + ".png");
Uri uri = null;
if (mediaFile != null) {
uri = Uri.fromFile(mediaFile);
}
return uri;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK
&& requestCode == CAMERA_REQUEEST_CODE) {
String path =fileUri.getPath();
//decode the path to bitmap here
}
}

Fragment of SlideTabLayout: store Bitmap

i am using the API21 SlidingTabLayout and SlidingTabStrips for my application.
I am saving an .tmp file of my intent camera photo. that works fine and i can see it on my phone package directory but i can store this .tmp file as .png ( i want to change the resolution because i need <1mb files instead of the 3mb files from the photo API intent)
i tried so many things in the last two hours and i can't solve it.
here is my code:
starting the intent with: takeAPicture
private void takeAPicture(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile(getView().getContext())));
startActivityForResult(intent, TAKE_PHOTO_CODE);
}
the path of my .tmp file: getTempFile
private File getTempFile(Context context){
final File path = new File(Environment.getExternalStorageDirectory(), getView().getContext().getPackageName());
if(!path.exists()){
path.mkdir();
}
return new File(path, "test.tmp");
}
at least i handle the ActivityResult:
public void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.i(TAG, "onActivityResult: Joined");
if(resultCode == Activity.RESULT_OK){
switch (requestCode){
case TAKE_PHOTO_CODE:
final File file = getTempFile(getView().getContext());
Toast.makeText(getActivity().getApplicationContext(), "Uri: " + Uri.fromFile(file), Toast.LENGTH_LONG);
try{
Bitmap captureBmp = MediaStore.Images.Media.getBitmap(getActivity().getApplicationContext().getContentResolver(), Uri.fromFile(file));
FileOutputStream fos = new FileOutputStream(new File(new File(Environment.getExternalStorageDirectory(), getView().getContext().getPackageName()),"done.png"));
captureBmp.compress(Bitmap.CompressFormat.PNG, 90, fos);
fos.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
break;
}
}
}
The fact is, the .tmp file is stored and the uri for
Bitmap captureBmp = MediaStore.Images.Media.getBitmap(getActivity().getApplicationContext().getContentResolver(), Uri.fromFile(file));
is correct.
hope someone can help me

You can use my code:
public static boolean saveImage(Context context, byte[] image, String filename) {
Bitmap bitmapImage = BitmapFactory.decodeByteArray(image, 0, image.length);
return saveImage(context, bitmapImage, filename);
}
public static boolean saveImage(Context context, Bitmap image, String filename) {
try {
FileOutputStream fos = context.openFileOutput(filename,Context.MODE_PRIVATE);
imagem.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.close();
File file = context.getFileStreamPath(filename);
} catch (Exception e) {
return false;
}
return true;
}

capture photo inside app with original resolution in android

I'm using camera intent to capture image inside my android app. After capturing I save pics into mobile internal/External storage in a specific folder. The problem is that these pics are not being saved in that resolution which camera has normally, their resolution is very low.
here is my code
Intent intent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 0);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
Bitmap bp = (Bitmap) data.getExtras().get("data");
/*********** Load Captured Image And Data Start ****************/
String extr = Environment.getExternalStorageDirectory().toString()
+ File.separator + "ScannerMini";
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss")
.format(new Date());
imageName = timeStamp + ".jpg";
if (Environment.MEDIA_MOUNTED.equals(state)) {
// We can read and write the media
myPath = new File(getExternalFilesDir(filepath), imageName);
//File myPath = new File(extr, imageName);
}
else{
myPath = new File(extr, imageName);
}
FileOutputStream fos = null;
try {
fos = new FileOutputStream(myPath);
bp.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
MediaStore.Images.Media.insertImage(getApplicationContext()
.getContentResolver(), bp, myPath.getPath(), imageName);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
can anybody tell me that what should i do to save image in original resolution. Any help would be much appreciated. Thank You :)

Bitmap bp = (Bitmap) data.getExtras().get("data");
By doing this you will only get a thumbnail image. You need to specify MediaStore.EXTRA_OUTPUT option in your capture intent. This is a path where captured image will be stored. Refer to android docs Taking Photos Simply

Save bitmap from selected file as new file into my own app folder

I just want to know on how can I save the image I selected from the gallery into my own folder as well as rename it but all the properties should remain in tact. Well I already have this method which came from a tutorial from vogella where you can select from gallery and display it as a preview. But instead of preview I just wanted do the thing I mentioned above. Here's the code:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
/*this method is used for getting and selecting image from gallery and display it in the imageView*/
InputStream stream = null;
if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK)
try {
if (bitmap != null) {
bitmap.recycle();
}
stream = getContentResolver().openInputStream(data.getData());
bitmap = BitmapFactory.decodeStream(stream);
preview.setImageBitmap(bitmap);
//instead setting it in preview, save it in your image folder and rename it
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
Well I do know some parts about saving a file but I'm really lost with this one so hope someone can help me. Thanks in advance.

private String saveToInternalSorage(Bitmap bitmapImage){
ContextWrapper cw = new ContextWrapper(getApplicationContext());
File directory = cw.getDir("directoryName", Context.MODE_PRIVATE);
File mypath=new File(directory,"profile.jpg");
FileOutputStream fos = null;
try {
// fos = openFileOutput(filename, Context.MODE_PRIVATE);
fos = new FileOutputStream(mypath);
// Use the compress method on the BitMap object to write image to the OutputStream
bitmapImage.compress(Bitmap.CompressFormat.PNG, 100, fos);
fos.close();
} catch (Exception e) {
e.printStackTrace();
}
return directory.getAbsolutePath();
}

Do this
public String writeFileToInternalStorage(Context context, Bitmap outputImage) {
String fileName = Long.toString(System.currentTimeMillis()) + ".png";
final FileOutputStream fos = openFileOutput(fileName, Context.MODE_PRIVATE);
outputImage.compress(CompressFormat.PNG, 90, fos);
}
