Saving images to a file android - android

I need help with my issue of saving a picture . I am using adobe photo sdk to edit my image. Documentation link(https://creativesdk.adobe.com/docs/android/#/articles/imageediting/index.html). They say use .withOutput(Uri) to save the image which i created but get my image with an error.

The Image Editor developer guide currently says that you should pass a Uri to withOutput(), but this is incorrect.
Try passing a File:
/* 1) Change the argument to your desired location */
File file = new File(Environment.getExternalStorageDirectory() + File.separator + "test.jpg");
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
Intent imageEditorIntent = new AdobeImageIntent.Builder(this)
.setData(imageUri)
.withOutput(file) /* 2) Pass the File here */
.build();
Your argument to the File constructor should be altered to whatever location you desire.

i capture image from camera it work fine but when i open again my app image not save

I have an app in which I try to capture user images from camera and also from gallery. The image capture works fine and the image is visible in the ImageView but when I restart the app the image disappears as if it wasn't saved.

While restart the app image is not showing becuase of all variable initialize again, for showing that you have to store it path locally.

Radio button unchecks itself after radiobutton.setChecked(false)

In my activity onCreate I set a onCheckedChangeListener to a radio group.
At some point I need to programmatically uncheck any checked radio button within the radio group so I unset the listener, uncheck the button, and set the listener back to prevent it from firing when programmatically unchecking the button.
When first checking the radio button, it takes a photo trough an intent. In the onActivityResult part, I uncheck the button if the user didn't take a photo. After doing this, the radio button unchecks itself whenever it's checked. How can I fix this problem?
This is my code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_checklist_vestuarios);
instanciar_objetos();
instanciar_listeners();
}
private void instanciar_objetos(){

listener_radio_groups = new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup radioGroup, int i) {
last_rg = radioGroup;
seleccionar_radio((RadioButton) findViewById(last_rg.getCheckedRadioButtonId()));
}
};
rg_1.setOnCheckedChangeListener(listener_radio_groups);
}
private void seleccionar_radio(RadioButton rb){
String tag = (String) rb.getTag();
String[] s = tag.split("_");
seccion = s[0];
item = s[1];
radio = s[2];
if(radio.equalsIgnoreCase("1")){
//MARCÓ SI, MANDARLE CON LA FOTO

try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File

}
// Continue only if the File was successfully created
if (photoFile != null) {
try{
Uri photoURI = FileProvider.getUriForFile(ctx,
BuildConfig.APPLICATION_ID + ".provider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, 1);
}
catch (Exception e){
e.printStackTrace();
}
}
}
}
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("ddMMyyyy_HHmmss").format(new Date());
String imageFileName = timeStamp;
String root = Environment.getExternalStorageDirectory().toString() + "/hrtech/hites/originales";
File storageDir = new File(root, "/"+seccion+"/"+item);
storageDir.mkdirs();
File image = File.createTempFile(

Android onclick radio button camera intent not working

i have a radio button. when i click on radio button camera intent is opened after taking a image using camera. image is not updating to image view.
i have used all permissions in my manifest file.
RB_PhotoStatus
.setOnCheckedChangeListener(new android.widget.RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group,
int checkedId) {
switch (checkedId) {
case R.id.yes:
//photoCollected = "Yes";
// create intent with ACTION_IMAGE_CAPTURE action
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 0);
break;
case R.id.no:
photoCollected = "No";
break;
}
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Bitmap bp = (Bitmap) data.getExtras().get("data");
imageView1.setImageBitmap(bp);
}
Taking Photos Simply!
This answer explains how to capture photos using an existing camera application.
<manifest ... >
<uses-feature android:name="android.hardware.camera"
android:required="true" />
...
</manifest>
Request for camera application.
static final int REQUEST_IMAGE_CAPTURE = 1;
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
Camera return intent with data on Activity override function onActivityResult as bellow:-
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
mImageView.setImageBitmap(imageBitmap);
}
}
For more info follows this link given bellow:
http://developer.android.com/training/camera/photobasics.html
It doesn't work because Camera Intent won't return the entire BitMap, but only the reference (Uri) to the created file.
Uri selectedImage = data.getData();
From this Uri you may re-load the BitMap using BitmapFactory.decodeFile
On radiobuttonclick();
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
onActivityResult();
Uri originalUri = data.getData();
imageview.setImageURI(originalUri);
And If you want to get bitmap then
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), originalUri);
private String mCurrentPhotoPath;
final String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
final File image = create_directory();
// Save a file: path for use with ACTION_VIEW intents
try {
mCurrentPhotoPath = image.getAbsolutePath();
} catch (Exception e) {
e.printStackTrace();
}
final Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
if (image != null) {
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(image));
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
} else {
snackbar = Snackbar.make(findViewById(android.R.id.content), "An error has occurred", Snackbar.LENGTH_SHORT);
snackbar.setAction("Dismiss", clickListener);
snackbar.show();
}
}
}
public File create_directory() {
// Create an image file name
final String imageFileName;
final String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.ENGLISH).format(new Date());
final String user_id = "1_";
imageFileName = user_id + timeStamp + "_";
final String proj_name = "test";
final String folder_timeStamp = new SimpleDateFormat("yyyyMMdd", Locale.ENGLISH).format(new Date());
final String path = "/TEST/" + proj_name + "/" + folder_timeStamp;
final File dr = new File(Environment.getExternalStorageDirectory().getAbsolutePath(), path);
if (!dr.exists()) {
dr.mkdirs();
}
File image = null;
try {
image = File.createTempFile(imageFileName, ".jpg", dr);
} catch (IOException e) {
e.printStackTrace();
}
return image;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE) {
if (resultCode == RESULT_OK){
//do something with the image which is stored in mCurrentPhotoPath
}
}

The problem is with the parameter fileUri.getPath()
May be this is not properly initialized and as a result its value is null
Check the value of fileUri variable value before passing it to the function.
This will solve your problem

This looks like it will be a problem:
if(requestCode==FILECHOOSER_RESULTCODE)
{
if (requestCode == GALLERY_PICTURE)
unless FILECHOOSER_RESULTCODE and GALLERY_PICTURE are the same ints then statement will never pass.
It may be possible to use request code to distinguish between "types" of photos i.e.
protected static final int MY_FACE_PHOTO = 0;
protected static final int MY_CAR_PHOTO = 1;
protected static final int MY_HOUSE_PHOTO = 2;
And you may use Intent.putExtra(String name, String value) when you create Intents before starting new activity, like:
#NonNls protected static final String STRING_EXTRA = "string_extra";
#NonNls protected static final String CAMERA = "camera";
#NonNls protected static final String GALLERY = "gallery";
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
MediaStore.Images.Media.EXTERNAL_CONTENT_URI
cameraIntent.putExtra(STRING_EXTRA, CAMERA);
galleryIntent.putExtra(STRING_EXTRA, GALLERY)
startActivityForResult(takePicture,
MY_FACE_PHOTO /* put here your desired request code */)
After that in onActivityResult() method you may use them:
protected void onActivityResult (int requestCode, int resultCode, Intent intent)
{
super.onActivityResult(requestCode, resultCode, intent);
if(intent != null)
{
if(resultCode == Activity.RESULT_OK)
{
String extraString = intent.getStringExtra(STRING_EXTRA);
if(extraString.equals(CAMERA))
{
// ... i. e.
switch (requestCode)
{
case MY_FACE_PHOTO:
{
// ...
break;
}
case MY_CAR_PHOTO:
{
// ...
break;
}
case MY_HOUSE_PHOTO:
{
// ...
break;
}
default:
{
// ...
break;
}
}
}
else if(extraString.equals(GALLERY))
{
// ...
}
}
else
{
// ...
}
}
}
