Store bitmap image in Firebase android

I have a problem. I am making an app with backend firebase and i want to save the image in firebase. Is there any way to store the bitmap images in Firebase. I didn't get the right tutorial.. Please help.
here is code where I get the images and want to save that images in Firebase
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
File f = new File(Environment.getExternalStorageDirectory().toString());
for (File temp : f.listFiles()) {
if (temp.getName().equals("temp.jpg")) {
f = temp;
break;
}
}
try {
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
bitmap = BitmapFactory.decodeFile(f.getAbsolutePath(),
bitmapOptions);
mImageCapture.setImageBitmap(bitmap);
mTextImage.setVisibility(View.GONE);
String path = android.os.Environment
.getExternalStorageDirectory()
+ File.separator
+ "Phoenix" + File.separator + "default";
f.delete();
OutputStream outFile = null;
File file = new File(path, String.valueOf(System.currentTimeMillis()) + ".jpg");
try {
outFile = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, outFile);
outFile.flush();
outFile.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
} else if (requestCode == 2) {
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));
mImageCapture.setImageBitmap(thumbnail);
mTextImage.setVisibility(View.GONE);
}
}
}
And this is the code where I save the name , phone no and location in Firebase
if(isOnline()){
User myData = new User();
myData.setUsername(name);
myData.setPhoneno(phone);
myData.setLocation(location);
ref.child("DataBase").push().setValue(myData);
Toast.makeText(BasicInformation.this, "Data saved", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(BasicInformation.this, HomePage.class);
startActivity(intent);
finish();
}else{
openDialog();
}

For storing image into your database, you can either save image path or can save Base64 image into your database
Here, we are storing image path into database
private void captureImage() {
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_CAPTURE_IMAGE_REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// if the result is capturing Image
if (requestCode == CAMERA_CAPTURE_IMAGE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
settingImaePath(fileUri);
}
}
if (requestCode == PICK_IMAGE && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri filePath = data.getData();
try {
//Getting the Bitmap from Gallery
Log.i("file path", "" + filePath);
final Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
//Setting the Bitmap to ImageView
Date now = new Date();
android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);
File imageFile = null;
String mPath = null;
try {
// image naming and path to include sd card appending name you choose for file
mPath = Environment.getExternalStorageDirectory().toString() + "/" + now.getTime() + ".jpg";
imageFile = new File(mPath);
FileOutputStream outputStream = new FileOutputStream(imageFile);
int quality = 100;
bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
outputStream.flush();
outputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
UserProfile userProfile = new UserProfile();
userProfile.setImagePath(mPath);
ProfileTable.getInstance().add(signupBean); // Here setting gallery image path into ProfileTable
userImage.setImageBitmap(bitmap); // userImage is an Imageview
} catch (IOException e) {
e.printStackTrace();
}
}
public void settingImaePath(Uri fileUri) {
String filePath = fileUri.getPath();
if (filePath != null) {
// Displaying the image or video on the screen
previewMedia(filePath);
}
}
private void previewMedia(String filePath) {
// Checking whether captured media is image or video
Log.i("file path", "" + filePath);
// bimatp factory
BitmapFactory.Options options = new BitmapFactory.Options();
// down sizing image as it throw s OutOfMemory Exception for larger

options.inSampleSize = 8;
final Bitmap bitmap = BitmapFactory.decodeFile(filePath, options);
Date now = new Date();
android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);

Save image to custom folder android on onPictureTaken

i need to save an image to a custom folder in my phone.
my code is
#Override
public void onPictureTaken(byte[] data, Camera camera) {
if (data != null) {
FileOutputStream outStream = null;
try {
Random generator = new Random();
int n = 0000;
n = generator.nextInt(n);
String fName = "Image" + n + ".jpg";
outStream = new FileOutputStream(String.format(fName));
outStream.write(data);
outStream.close();
} catch (Exception e) {
e.printStackTrace();
}
camera.startPreview();
}
not working

#Override
public void onPictureTaken(byte[] data, Camera camera) {
if (data != null) {
Bitmap bitmap = BitmapFactory.decodeByteArray(data , 0, data .length);
if(bitmap!=null){
File file=new File(Environment.getExternalStorageDirectory()+"/dirr");
if(!file.isDirectory()){
file.mkdir();
}
file=new File(Environment.getExternalStorageDirectory()+"/dirr",System.currentTimeMillis()+".jpg");
try
{
FileOutputStream fileOutputStream=new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG,100, fileOutputStream);
fileOutputStream.flush();
fileOutputStream.close();
}
catch(IOException e){
e.printStackTrace();
}
catch(Exception exception)
{
exception.printStackTrace();
}
}
}
}
Dont forget to add permission:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

You can find ans from below code
#Override
public void onPictureTaken(byte[] data, Camera camera) {
if (data != null) {
Bitmap m_bitmap = BitmapFactory.decodeByteArray(data , 0, data .length);
String destinationPath = Environment.getExternalStorageDirectory() + "/" + "Image.jpg";
if (m_bitmap != null || destinationPath != null)
{
FileOutputStream m_out = new FileOutputStream(destinationPath);
m_bitmap.compress(Bitmap.CompressFormat.JPEG, 100, m_out);
}
}
Hope this code helps you

You first have to create the destination folder you want to save the file into. So, in your Android sdk folder, you create the MediaFiles folder. In this folder you can then create your file.
Here's some code you can try.
#Override
public void onPictureTaken(byte[] data, Camera camera) {
if (data != null) {
FileOutputStream outStream = null;
try {
Random generator = new Random();
int n = 0000;
n = generator.nextInt(n);
String fName = "Image" + n + ".jpg";
outStream = new FileOutputStream(GetPathForFileName(fName));
outStream.write(data);
outStream.close();
} catch (Exception e) {
e.printStackTrace();
}
camera.startPreview();
}
private String GetPathForFileName(String fileName)
{
try
{
String savePath = GetSaveFolderFromConfiguration();
File file = new File(savePath + "/" + fileName);
return savePath + "/" + fileName;
}
catch (Exception ex)
{
ExceptionForm.ShowException(ex);
}
return null;
}
public static String GetSaveFolderFromConfiguration() throws Exception
{
String path = Environment.getExternalStorageDirectory().toString() + "/MediaFiles";
File f = new File(path);
if (f.exists())
return path;
else
f.mkdir();
return path;
}

Captured image is not stored in the specific folder in android

I have created a program to capture the image and that is getting stored into sdcard/dcim/camera folder. Now I am trying to save the captured image in my own directory created in sdCard, say "/somedir".
I am able to make the directory programmatically but the image file is not getting stored in it.
Can anybody tell me where I am doing wrong here??
Here is the code....
File folder = new File(Environment.getExternalStorageDirectory() + "/abc");
Bitmap mybitmap1; //mybitmap1 contain image. So plz dont consider that I don't have image in mybitmap1;
if(!folder.exists())
{
success = folder.mkdir();
Log.i("Log", "folder created");
}
else
{
Log.i("Log", "Folder already present here!!");
}
String fname = date +".jpg";
file = new File( folder,fname);
if (file.exists ())
file.delete ();
capturedImageUri = Uri.fromFile(file);
FileOutputStream out;
byte[] byteArray = stream.toByteArray();
try {
out = new FileOutputStream(file);
mybitmap1.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
MediaStore.Images.Media.insertImage(getContentResolver(), mybitmap1, file.getName(), file.getName());
//MediaStore.Images.Media.insertImage(getContentResolver(),file.getAbsolutePath(),file.getName(),file.getName());
} catch (Exception e) {
e.printStackTrace();
}

Refer the below code
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode == RESULT_OK && requestCode == 1 ) {
final Uri selectedImage = data.getData();
try {
bitmap = Media.getBitmap(getContentResolver(),selectedImage);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
File f = new File(Environment.getExternalStorageDirectory()
+ File.separator
+ filename);
f.createNewFile();
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

You are settings the wrong file name for the file. Just use this method if you want to use time in the name of image file.
private Uri getImageUri() {
// Store image in dcim
String currentDateTimeString = getDateTime();
currentDateTimeString = removeChar(currentDateTimeString, '-');
currentDateTimeString = removeChar(currentDateTimeString, '_');
currentDateTimeString = removeChar(currentDateTimeString, ':');
currentDateTimeString = currentDateTimeString.trim();
File file = new File(Environment.getExternalStorageDirectory()
+ "/DCIM", currentDateTimeString + ".jpg");
Uri imgUri = Uri.fromFile(file);
return imgUri;
}
private final static String getDateTime() {
DateFormat df = new SimpleDateFormat("yyyy-MM-dd_hh:mm:ss");
df.setTimeZone(TimeZone.getTimeZone("PST"));
return df.format(new Date());
}
public static String removeChar(String s, char c) {
StringBuffer r = new StringBuffer(s.length());
r.setLength(s.length());
int current = 0;
for (int i = 0; i < s.length(); i++) {
char cur = s.charAt(i);
if (cur != c)
r.setCharAt(current++, cur);
}
return r.toString();
}

Hers is what you need to do:
instead of
File folder = new File(Environment.getExternalStorageDirectory() + "/abc");
do this
File folder = new File(Environment.getExternalStorageDirectory().getPath() + "/abc");
if(folder.exists()){
//save your file then
}
else{
folder.mkdirs();
//save your file then
}
Make sure you use the neccessary permissions in your Manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Android, can't read images I saved to data folder

My app uses the following piece of code to write out images I have resized into the app's data folder:
private void writeImage(Bitmap bmp, String filename)
{
try
{
FileOutputStream stream = openFileOutput(filename, MODE_WORLD_WRITEABLE);
bmp.compress(CompressFormat.PNG, 100, stream);
stream.flush();
stream.close();
}
catch(Exception e)
{
e.printStackTrace();
}
}
I am able to read them in a file browser (ddms) and can confirm they appear to have been written.
However, any attempt to load the images results in non-null bitmaps with width and height of -1. I am using the following code to load them:
imageList = getFilesDir().list();
Bitmap bmp = null;
for(String img : imageList)
{
try {
bmp = BitmapFactory.decodeStream(openFileInput(img));
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
EDIT: On further inspection, it seems, after conversion the images are of density 160 (and not 240 as they should be) also, after testing a working application it seems the -1 mWidth and -1 mHeight on the bitmaps is irrelevent.

I had same problem.my data folder given smallest image.and cursor return null pointer exception on my getDestination method.then i fixed like it
public void captureNewPhoto() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
targetFile = getOutputMediaFile(MEDIA_TYPE_IMAGE);
targetUri = Uri.fromFile(targetFile);
intent.putExtra(MediaStore.EXTRA_OUTPUT, targetUri);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, 12);
}
And i use like in onActivityResult();
BitmapFactory.Options options = new BitmapFactory.Options();
networkBitmap = BitmapFactory.decodeFile(targetUri.getPath(),
options);
//ImageDialog(networkBitmap);
//String path = getRealPathFromUri(this, Uri.parse(targetUri.getPath()));
String myDeviceModel = android.os.Build.MODEL;
deviceName = Build.MANUFACTURER;
if (myDeviceModel.equals("GT-I9500")) {
} else if (deviceName.contains("samsung")) {
} else {
exif = ReadExif(targetUri.getPath());
if (exif.equals("6")) {
matrixx.postRotate(90);
} else if (exif.equals("7")) {
matrixx.postRotate(-90);
} else if (exif.equals("8")) {
matrixx.postRotate(-90);
} else if (exif.equals("5")) {
matrixx.postRotate(-90);
}
//matrixx.postRotate(-90);
}
networkBitmap = Bitmap.createBitmap(networkBitmap, 0, 0, networkBitmap.getWidth(), networkBitmap.getHeight(), matrixx, true);
Log.e("Taget File ", "Size " + targetFile.length());
if (networkBitmap != null) {
ImageSetting(networkBitmap, System.currentTimeMillis() + filename);
}
public void ImageSetting(Bitmap imageBitmap, final String fileName) {
networkBitmap = imageBitmap;
organizator(networkBitmap, fileName);
networkBitmap = null;
}` public void tamamlandiOndenFoto(Bitmap turnedBitmap, String filename) {
frontFotoFile = storeBitmap(networkBitmap, filename);
ondenFotoPath = ondenFoto.getAbsolutePath();
ondenFotoImageView.setImageBitmap(turnedBitmap);
}`
public File storeBitmap(Bitmap bp, String fileName) {
File sd = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
File dest = new File(sd, fileName);
if (bp != null) {
try {
FileOutputStream out = new FileOutputStream(dest);
bp.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
Log.e("Alinan hata ", " Catch hata ", e);
}
return dest;
} else {
return null;
}
}
I hope give you any idea for your problem.
