I am trying to create an application that captures an image and stores it into my internal storage. When I change my codefrom File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES); to File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM); (due to absence of SD card on my phone), it does not open the camera and a file is stored in my DCIM folder. The file stored will be have an error "File format isn't supported or files are corrupted". If I use Environment.DIRECTORY_PICTURES instead it shows a preview of the camera and imageView but no files will be stored.
I am new and any help is greatly appreciated. Thanks in advance.
My code is as shown below
public static final int REQUEST_IMAGE_CAPTURE =1;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1) {
File imgFile = new File(mCurrentPhotoPath);
if (imgFile.exists()) {
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
ImageView myImage = (ImageView) findViewById(R.id.imageViewID);
myImage.setImageBitmap(myBitmap);
}
}
}
String mCurrentPhotoPath;
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
//File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
static final int REQUEST_TAKE_PHOTO = 1;
void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"com.example.android.fileprovider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
}

private static final int CAMERA_REQUEST = 1337;
private void showCamera() {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra("category", "camera");
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
I used this code to pick an image from the camera. and this is my activity result
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST ) {
filePath = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), filePath);
imageView.setImageBitmap(bitmap);
Toast.makeText(this, data.getDataString(), Toast.LENGTH_SHORT).show();
} catch (IOException e) {
e.printStackTrace();
}
}
else if (requestCode == CAMERA_REQUEST) {
filePath = data.getData();
Log.i("hello", "REQUEST cALL");
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), filePath);
imageView.setImageBitmap(bitmap);
} catch (Exception e) {
Log.i("hello", "Exception" + e.getMessage());
}
}
the camera is fine. and I can capture it
but why imageview cant pick the photos from camera?
but if I am picking from storage the imageview can change the image.
can you see the false code?
To use image file path you have to do like below
1) Write a method to create an image file
String currentPhotoPath;
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
currentPhotoPath = image.getAbsolutePath();
return image;
}
2) Call camera intent
private void showCamera() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"com.example.android.fileprovider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
3) Now, you need to configure the FileProvider. In your app's manifest, add a provider to your application:
<application>
...
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths"></meta-data>
</provider>
...
</application>
4) create a resourse file res/xml/file_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images"
path="Android/data/com.example.package.name/files/Pictures" />
</paths>
Note: Make sure that you replace com.example.package.name with the actual package name of your app.
5) Obtain the imageFilePath
if (requestCode == CAMERA_REQUEST) {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), currentPhotoPath);
imageView.setImageBitmap(bitmap);
// or you can use Glide to show image
Glide.with(this).load(currentPhotoPath).into(imageView);
}
Hope it works as you expect. for details you can see google Official documents!
Try this, Hope it will help you.
if (requestCode == CAMERA_REQUEST) {
Bitmap bitmap= (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(bitmap);
}
data.getData();
This one doesnt give you a filepath of the captured image
You can follow this one
Getting path of captured image in Android using camera intent
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
//get the URI of the bitmap from camera result
Uri uri = getImageUri(getApplicationContext(), photo);
// convert the URI to its real file path.
String filePath = getRealPathFromURI(uri);
}
This method gets the URI of the bitmap that you can use to convert it to a file path
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}
this method converst a URI to a file path
public String getRealPathFromURI(Uri uri) {
String path = "";
if (getContentResolver() != null) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
if (cursor != null) {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
path = cursor.getString(idx);
cursor.close();
}
}
return path;
}
I am developing an app that can take pictures using intents and save it to storage. After taking 10 to 15 pictures the app is gets very slow. Code for taking picture is as follows:
private void capturePhoto() {
File root = new File(Environment.getExternalStorageDirectory(), "Feedback");
if (!root.exists()) {
root.mkdirs();
}
File file = new File(root, Constants.PROFILE_IMAGE_NAME + ".jpeg");
Uri outputFileUri = Uri.fromFile(file);
Intent photoPickerIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
photoPickerIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
photoPickerIntent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
photoPickerIntent.putExtra("return-data", true);
photoPickerIntent.putExtra("android.intent.extras.CAMERA_FACING", 1);
startActivityForResult(photoPickerIntent, requestCode);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (this.requestCode == requestCode && resultCode == RESULT_OK) {
File file = new File(root, Constants.PROFILE_IMAGE_NAME+".jpeg");
checkFlowIdisPresent(file);
displayPic();
}
}
private void displayPic() {
String filePath = Environment.getExternalStorageDirectory()
.getAbsolutePath() + File.separator + "/Feedback/" + Constants.PROFILE_IMAGE_NAME + ".jpeg";
// Bitmap bmp = BitmapFactory.decodeFile(filePath);
//Bitmap scaled = Bitmap.createScaledBitmap(bmp, 300, 300, true);
File imgFile = new File(filePath);
Bitmap bmp = decodeFile(imgFile);
if (imgFile.exists()) {
dispProfilePic.setImageBitmap(bmp);
} else {
dispProfilePic.setBackgroundResource(R.drawable.user_image);
}
}
Edited DisplayPic() method is shown above
You need to use a image loading library to load the images.
Glide is my fav one.
its setup is very simple:
put this n your build.gradle
dependencies {
compile 'com.github.bumptech.glide:glide:3.7.0'
}
Then your method will be
private void displayPic() {
String filePath = Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "/Feedback/" + Constants.PROFILE_IMAGE_NAME + ".jpeg";
Glide.with(context).load(filePath).override(300, 300).into(dispProfilePic);
}
You can find more informatin and usage details here.

Are you running this on marshmallow? Because if you are, the permission structure has changed. And you should read the documentation # http://developer.android.com/training/permissions/index.html .
The user must grant the permission explicitly.
you need to add user permission to androidmanifest.xml
<uses-permission android:name="android.permission.CAMERA" />
if you need to store the image to storage you have to add :
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
I'm trying to build an app that when a button is pressed the camera intent is launched and the user takes a picture that is then displayed in my app. The problem I am having is that in onActivityResult the resultCode is -1 and the intent is null. I've based my code off this sample from google
My code looks like this:
private static final int CAMERA_PIC_REQUEST = 1337;
private String mCurrentPhotoPath;
public void cameraClick(View view){
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if(cameraIntent.resolveActivity(getPackageManager()) != null){
File photo = null;
try{
photo = createImageFile();
}
catch (IOException e){
e.printStackTrace();
}
if(photo != null){
//cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
}
}
private File createImageFile() throws IOException {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
return image;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
if(requestCode == CAMERA_PIC_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null){
//do image setting here
}
}
I'm trying to store a newly captured image through the Camera on my Storage and then display the image on an imageview. However, the image does not get stored.
My code:
private SurfaceView mSurfaceView;
private SurfaceHolder mSurfaceHolder;
private Camera mCamera;
......more code...
captureImage.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mCamera.takePicture(null, null, new PictureCallback() {
#Override
public void onPictureTaken(byte[] data, Camera camera) {
File pictureFile;
pictureFile = new File(String.format("/sdcard/%d.jpg", System.currentTimeMillis()));
try {
FileOutputStream fos = new FileOutputStream(pictureFile);
fos.write(data);
fos.close();
}
catch (Exception e) {
Log.d("ERR",e.toString());
}
//Display
Uri uri = Uri.fromFile(pictureFile);
imageViewer.setImageURI(uri);
}
});
}
});
Is my code correct for writing and displaying the image? I do not see any image on my storage and the imageview doesn't get populated by the image either. What am I doing wrong?
Create folder where you want to keep your photos.
Give full path name to create file .
//in this example MyImages is folder where you will keep your photos
File storageDir = new File(Environment.getExternalStorageDirectory() + "/", "MyImages");
if (!storageDir.exists()) {
storageDir.mkdirs();//directory created
}
// get the current timestamp
String timest = new SimpleDateFormat("yyyyMMdd_HHmmss")
.format(new Date());
//Create your picture file
File pictureFile;
pictureFile = new File(storageDir.getPath()+File.separator+ "IMG_" + timeStamp + ".jpg");
1- make sure you have what it takes Permissions
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
2- Create a directory on your mobile
public static void createDirectory(Context context) {
String directoryPath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).getAbsolutePath() + "/YOURDIRECTORYNAME";
try {
File directory = new File(directoryPath);
if (!directory.exists()) {
directory.mkdirs();
}
} catch (Exception e) {
e.printStackTrace();
}
}
3- This method used to take the photo and create file.
private void takePictures() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null) {
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
}
if (photoFile != null) {
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}
4- Creates the file and save it in the folder.
private File createImageFile() throws IOException {
Calendar c = Calendar.getInstance();
SimpleDateFormat timeData = new SimpleDateFormat("dd-MMM-yyyy-HH:mm:ss");
//TODO declared global variables datePicture and imageFileName
datePicture = timeData.format(c.getTime());
imageFileName = Config.IMAGE_NAME_DEFOULT + datePicture;
File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES + "/YOURDIRECTORYNAME");
File image = File.createTempFile(imageFileName, ".png", storageDir);
Log.v("test_photo" ,image.getName());
//TODO declared global variables fileName and mCurrentPhotoPath
fileName = image.getName();
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
5- Get the picture reveal it in your imageView and save in your DB.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_IMAGE_CAPTURE) {
if (resultCode == getActivity().RESULT_OK) {
//show directly
Bundle extras = data.getExtras();
Bitmap bitmap = extras.get("data");
youtImageView.setImageBitmap(bitmap);
/* here show in your imageView directly or
insert into database variables fileName and mCurrentPhotoPath
then you'll have to get it if you want to display from the DB */
} else if (resultCode == getActivity().RESULT_CANCELED) {
}
}
}
I hope it helps!
First, does your app's manifest contain the necessary permission to write to the SD card?
<manifest ...>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
...
</manifest>
and second, I'm not sure that you have the correct path to the SD card. The API docs suggest:
File sdPath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
String filename = Long.toString(System.currentTimeMillis())+".jpg";
File pictureFile;
pictureFile = new File(sdPath, filename);
EDIT: To display the image using the URL, you could try:
FileInputStream inputStream = new FileInputStream(pictureFile);
Drawable d = Drawable.createFromStream(inputStream, pictureFile.getName());
imageViewer.setImageDrawable(d);
