When I start the application, I upload an image using Picasso to imageview. I'm trying to make the user upload their own image. If I take a picture or select it from the gallery, I can display it in an imageview. But I would like to use SharedPreferences to display the image the next time I load the application, which I unfortunately can't do.
Here is my code.
private void showImageOptionDialog(){
final String[] options = getResources().getStringArray(R.array.image_options);
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle(R.string.alert_dialog_title)
.setItems(options, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
switch (which){
case 0:
Intent cameraIntent = new Intent();
cameraIntent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 11);
break;
case 1:
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, 9);
break;
case 2:
SaveSharedPreference.setAvatar(context, "none");
recreate();
break;
}
}
});
AlertDialog dialog = builder.create();
dialog.show();
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
//Check if the intent was to pick image, was successful and an image was picked
if(requestCode == 9 && resultCode == RESULT_OK && data != null){
//Get selected image uri from phone gallery
Uri selectedImage = data.getData();
//Display selected photo in image view
//head_image.setImageURI(selectedImage);
assert selectedImage != null;
SaveSharedPreference.setAvatar(context, selectedImage.toString());
}
//Handle camera request
else if(requestCode == 11 && resultCode == RESULT_OK && data != null){
//We need a bitmap variable to store the photo
Bitmap bitmap = (Bitmap) Objects.requireNonNull(data.getExtras()).get("data");
//Display taken picture in image view
head_image.setImageBitmap(bitmap);
}
recreate();
}
Then I try to load using
Picasso.get()
.load(SaveSharedPreference.getAvatar(context))
.placeholder(R.mipmap.ic_launcher)
.transform(new CropCircleTransformation())
.into(head_image);
Thank you for your help
(application runs on Android 7.0+)
It's NOT a good idea to save a photo using SharedPreferences. Try caching it or use a local Database or File system to store and/or restore them

I have an app where a user is registered and can have a profile image. In the realtime database I have these information saved. Now I want to be able to change the informatiom, particulary profile image. Here is my realtime database:
When the user clicks on his/hers image the camera intent starts:
private void startCamera() {
//start the camera
Intent cInt = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cInt,REQUEST_IMAGE_CAPTURE);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_IMAGE_CAPTURE) {
if (resultCode == RESULT_OK) {
//picture as image
Bitmap bp = (Bitmap) data.getExtras().get("data");
mProfileRoundedImageView.setImageBitmap(bp);
//here I want to save Image uri and update my firebase with the new uri...
}
}
}
How can I do that?? I have searched alot how to convert captured image to uri and then update imageurl but with no luck. Please help.
BTW I do not want to save the image to the sd, just convert to uri and update firebase...
You can use the below function.
public Uri getImageUri(Context inContext, Bitmap inImage) {
Bitmap OutImage = Bitmap.createScaledBitmap(inImage, 1000, 1000,true);
String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), OutImage, "Title", null);
return Uri.parse(path);
}
Just call it in the onActivityResult() after you extract bitmap
Feel free to ask if something is unclear
I am using the library https://github.com/Yalantis/uCrop provided here.
I want to open gallery intent directly when a button is clicked with crop option facility but how do I do it??
Currently, am doing this
public void onclickbutton (View view) {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
if (checkPermissionREAD_EXTERNAL_STORAGE(this)) {
startActivityForResult(intent, GALLERY_INTENT);
}
}
in Onactivity result
if (requestcode == GALLERY_INTENT && resultcode == RESULT_OK)
{
uri = data.getData();
UCrop.of(uri, uri)
.withAspectRatio(16, 9)
.withMaxResultSize(500, 500)
.start(this);
}
Again in onactivity result
if (resultcode == RESULT_OK && requestcode == UCrop.REQUEST_CROP) {
final Uri resultUri = UCrop.getOutput(data);
Toast.makeText(this, resultUri.toString(), Toast.LENGTH_SHORT).show();
} else if (resultcode == UCrop.RESULT_ERROR) {
final Throwable cropError = UCrop.getError(data);
}
Please help me where I am going wrong..
You need to change your Onactivity result
you are passing same uri you must pass source uri and destination uri. like shown below
UCrop.of(sourceUri, destinationUri)
.withAspectRatio(16, 9)
.withMaxResultSize(maxWidth, maxHeight)
.start(context);
I want to call the android's native camera and don't save it in the storage, because I save it myself after processing image. It works almost for all devices, except Motorola XT1032 (Android 5.1, API 22). So is there a way to tell the camera not to save the picture?
Here is how I call the camera intent.
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) + File.separator + "image_"+System.currentTimeMillis()+".jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
((Activity) mContext).startActivityForResult(intent, 1001);
Create the request code variable:
private static final int REQUEST_CAMERA = 1;
Open the camera:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);
and in case you want to show it to the user:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQUEST_CAMERA:
if (resultCode == RESULT_OK) {
// successfully captured the image
Bitmap mBitmap = (Bitmap) data.getExtras().get("data");
if (mBitmap != null) {
imageView.setImageBitmap(mBitmap);
}
}
}
I'm making an app that will let users password-protect photos. So far, the user can take a photo and the photo gets displayed. However, all the photos get saved to camera roll. How can I save them to the app instead of camera roll so they can be private, but still be able to access them from their uri (which I will save to SharedPreferences) ?
int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 0;
Uri imageUri;
public void takePic(View view){
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
imageUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "filename_" +
String.valueOf(System.currentTimeMillis()) + ".jpg"));
intent.putExtra("data", imageUri);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
Bundle extras = data.getExtras();
Log.e("URI", imageUri.toString());
Bitmap bmp = (Bitmap) extras.get("data");
ImageView imageView = (ImageView) findViewById(R.id.imageView);
imageView.setImageBitmap(bmp);
}
else if (resultCode == RESULT_CANCELED) {
Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT);
}
}
}
create a file named (.nomedia) in the folder, then all the photos in this folder will not be shown!
OR
Save your photos on Internal storage.
I am new to Android programming and I'm writing an application in Java that opens the camera take a photo and save it. I made it via Intents but I can't see onActivityResult running.
I have tested it into my phone (Samsung Galaxy S) and when I take the photo I receive a preview of that photo having two buttons one Save and the other Cancel. I haven't added something to my code to do this so I think it's something that camera does. I want after capturing the image to run onActivityResult (after I press the Save button on the preview).
But how I'm going to return a result to start onActivityResult after pressing the Button Save on the preview?
I FORGOT to tell that after i press save my entire app is terminated.
Here is my Code
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TakePicButton = (Button) findViewById(R.id.TakePicture);
TakePicButton.setOnClickListener((android.view.View.OnClickListener) this);
}
#Override
public void onDestroy(){
super.onDestroy();
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
// Image captured and saved to fileUri specified in the Intent
Toast.makeText(this, "Image saved to:\n" + data.getData(), Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_CANCELED) {
Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT);
} else {
Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT);
}
}
public void onClick(View v) {
// TODO Auto-generated method stub
if(v.getId() == R.id.TakePicture){
// create Intent to take a picture and return control to the calling application
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
// start the image capture Intent
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
}
try the below code, you will have to modify it a bit, it will help you get From Library and From Camera both, the SELECT_PICTURE is used for getting image from library
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case SELECT_PICTURE:
Uri selectedImageUri = data.getData();
filemanagerstring = selectedImageUri.getPath();
selectedImagePath = getPath(selectedImageUri);
if (selectedImagePath != null)
myFile = new File(selectedImagePath);
else if (filemanagerstring != null)
myFile = new File(filemanagerstring);
if (myFile != null) {
Bitmap bmp_fromGallery = decodeImageFile(selectedImagePath);
break;
case CAMERA_REQUEST:
Bitmap bmp_Camera = (Bitmap) data.getExtras().get("data");
break;
default:
break;
}
}
