I am creating my first project using Android Studio, I am aiming to create an app where you can load photos in from the phones memory and display them so people can see.
I've managed to get it working sort of how I want it to, the pictures in the gallery stay where they should do when I close out of the app and then reopen it - however if I close the app restart it and then try and add a new photo it overwrites the gallery and deletes the pictures I orginally put in. Does anyone have any ideas on how I can fix this? I tried playing with when I create the images ArrayList but that didn't help.
Code:
Main Activity
public class MainActivity extends AppCompatActivity {
private static final int PERMISSION_REQUEST = 0;
private static final int RESULT_LOAD_IMAAGE = 1;
public static final String MyPREFERENCES = "MyPrefs" ;
public static final String Name = "nameKey";
ImageView imageView;
Button uploadButton;
Button savedPhotos;
List<String> images;
String imageCreated;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(Build.VERSION.SDK_INT > Build.VERSION_CODES.M && checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED){
requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, PERMISSION_REQUEST);
}
imageView = (ImageView) findViewById(R.id.imageView);
uploadButton = (Button) findViewById(R.id.button);
savedPhotos = (Button) findViewById(R.id.button2);
SharedPreferences sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedpreferences.edit();
images = new ArrayList<>();
uploadButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAAGE);
SharedPreferences sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString(imageCreated, "Complete");
}
});
savedPhotos.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
openPage2();
}
});
}
public void openPage2()
{
Intent intent = new Intent(this, SavedPhotos.class);
startActivity(intent);
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
switch(requestCode)
{
case PERMISSION_REQUEST:
if(grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
Toast.makeText(this, "Permission Granted", Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(this, "Permission Not Granted", Toast.LENGTH_SHORT).show();
finish();
}
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
switch(requestCode)
{
case RESULT_LOAD_IMAAGE:
if(resultCode == RESULT_OK)
{
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
images.add(picturePath);
StringBuilder stringBuilder = new StringBuilder();
for(String i : images)
{
stringBuilder.append(i);
stringBuilder.append(",");
}
SharedPreferences sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString("images", stringBuilder.toString() );
editor.commit();
}
}
}}
And SavedPhotos
public class SavedPhotos extends AppCompatActivity {
public static final String MyPREFERENCES = "MyPrefs" ;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_saved_photos);
SharedPreferences sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedpreferences.edit();
String wordsString = sharedpreferences.getString("images", "");
String[] itemWords = wordsString.split(",");
List<String> items = new ArrayList<String>();
LinearLayout layout = (LinearLayout) findViewById(R.id.linear);
for(int i = 0; i < itemWords.length; i++) {
ImageView imageView = new ImageView(this);
imageView.setId(i);
imageView.setPadding(2, 2, 2, 2);
imageView.setImageBitmap(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher_foreground));
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
layout.addView(imageView);
items.add(itemWords[i]);
imageView.setImageBitmap(BitmapFactory.decodeFile(items.get(i)));
}
}}

I actually run to same issues before until i met a well made library and requires nothing and made my code much good looking, FastSave: https://github.com/yehiahd/FastSave-Android.

I am developing a gallery application, I display all the icons from the external storage into my application. I followed the tutorial from the below link and it is working.
https://deepshikhapuri.wordpress.com/2017/03/20/get-all-images-from-gallery-in-android-programmatically/
Now in addition to this, I provide an option for the user to take a picture from the application and save it to the gallery. When the picture is taken using the Camera intent, the image gets actually saved in the gallery. But I have to intent to another fragment and come back to the Gallery to see the picture I have taken.
To see the changes immediately, onActivityResult() of the Camera intent, I am recreating the fragment. But the problem occurs when we click the back button. The recreated fragment stays in the backstack forever. I am brain faded searching for answers. Any help is appreciated.

The exact problem of what is happening
Any help is appreciated.
I am building an app in which I want when the user clicks the imageview, the device camera app to launch and take a picture and set it to the imageview. I have accomplished that!!! But when I exit the app and re-open it the image has been deleted. How can I do it so the image is permanent?
My code:
private SessionManager session;
private static final int REQ_CODE = 1152;
public static final int MEDIA_TYPE_IMAGE = 1;
public static final int MEDIA_TYPE_VIDEO = 2;
private Uri file;
private String fileName = "ImageTaken";
private ImageView imagePhoto;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_data);
session = new SessionManager(getApplicationContext());
session.checkLogin();
HashMap<String, String> user = session.getUserDetails();
Toolbar tb = (Toolbar)findViewById(R.id.topBar);
setSupportActionBar(tb);
String name = user.get(SessionManager.KEY_NAME);
TextView watersName = (TextView)findViewById(R.id.waitersName);
TextView date = (TextView)findViewById(R.id.date);
TextView time = (TextView)findViewById(R.id.time);
watersName.setText(Html.fromHtml("<b>" + name + "</b>"));
Calendar c = Calendar.getInstance();
SimpleDateFormat dateFormat = new SimpleDateFormat("dd" + "/" + "mm" + "/" + "yyyy");
String text = dateFormat.format(c.getTime());
date.setText(text);

#Override
public void onClick(View v) {
DialogMessageDisplay.displayInfoMessage(UserData.this, "Payment Details", "There was no order made. \n Make an order and then tap the payment button.", AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);
}
});
imagePhoto = (ImageView)findViewById(R.id.waiterPhoto);
imagePhoto.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
file = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

}
OnActivityResult
#Override

if(requestCode == REQ_CODE){
if(resultCode == RESULT_OK){
imagePhoto.setImageURI(file);
editor.putString(fileName, file.toString());
editor.commit();
Toast.makeText(UserData.this, "Your file has been saved at " + file, Toast.LENGTH_SHORT).show();
}else if(resultCode == RESULT_CANCELED){
Toast.makeText(UserData.this, "Action Cancelled", Toast.LENGTH_SHORT).show();
}
}
}
Thanks in advance!!!
Try this:
1) Initialize these:
private SharedPreferences sharedPreferences;
private SharedPreferences.Editor editor;
2) Modify your onCreate() like:
sharedPreferences = getSharedPreferences(fileName, MODE_PRIVATE);
editor = sharedPreferences.edit();
imagePhoto = (ImageView)findViewById(R.id.waiterPhoto);
String commited = sharedPreferences.getString(fileName, null);
if(commited != null) {
imagePhoto.setImageURI(Uri.parse(commited));
}
3) Modify your onActivityResult() like:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == REQ_CODE){
if(resultCode == RESULT_OK){
imagePhoto.setImageURI(file);
editor.putString(fileName, file.toString());
editor.commit();
}else if(resultCode == RESULT_CANCELED){
Toast.makeText(UserData.this, "Action Cancelled", Toast.LENGTH_SHORT).show();
}
}
}
And then you will have your desired effect. Hope it helps!!!
SharedPreferences are not meant for holding quantities of data such as imagery. They are meant for holding information about where an image is, or other small selections that the user has chosen.
If you want to save an image off, then you should do just that. Save the image within a local file within the application and then retrieve it later. You can save the location of that file in a SharedPreference object if you would like for you when you return. If it is only one, then you can replace it with the next one in the same file name the next time a picture is taken. This way you always have the latest image available since the last time that picture is taken; even after you shut down and restart the phone.
I'm trying to store a photo in SharedPreferences that it took from inside my app.
but i cant find any code that will help me with that.
can you help me with it please ?

and how can i can get the code out in other activity ?
The way I'm using to store images using SharedPreferences is to encode your image bitmap to a String then store that string, and then when needing the image retrieve that String and decode it again to a bitmap:
// declaring the sharedPreferences
SharedPreferences sharedPreferences = PreferenceManager
.getDefaultSharedPreferences(this);
// encoding image bitmap to String
int size = userImage.getWidth() * userImage.getHeight();
ByteArrayOutputStream stream = new ByteArrayOutputStream(
size);
userImage.compress(Bitmap.CompressFormat.JPEG, 50,
stream);
byte[] b = stream.toByteArray();
Editor editor = sharedPreferences.edit();
editor.putString("userImage", encodedImage);
editor.commit();
stream.close();
stream = null;
// then when needing that image again from the SharedPreferences
String decoded_image = sharedPreferences.getString("userImage", "default");
try{
byte[] decodedString = Base64.decode(decoded_image, Base64.DEFAULT);
Bitmap stored_userImage = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
// do whatever you want with it now
}catch(OutOfMemoryError oom){
}
I'm trying to take a photo from gallery on a Dialog but I couldn't. I cannot call startActivityResult() method to override on Dialog. Does anybody know a way to do it on Dialog?
Here is my code. (I need to do it in buttonG.setOnClickListener())
public class AddBirthdayDialog extends Dialog {

public AddBirthdayDialog(final Context context) {
super(context);
this.context = context;
setCanceledOnTouchOutside(false);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.addbirthday_layout);
myDB = new DB(context);
textName = (EditText) findViewById(R.id.editTextname);
textSname = (EditText) findViewById(R.id.editTextsname);
birthDate = (DatePicker) findViewById(R.id.datePicker);
Button buttonG = (Button) findViewById(R.id.buttonUploadG);
buttonG.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
**//Need to call gallery and take a photo's bitmap or byte[] here.**
}
});
Button buttonC = (Button) findViewById(R.id.buttonUploadC);
buttonC.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
Button cancelButton = (Button) findViewById(R.id.cancelbutton);
cancelButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {

}
});
Button save = (Button) findViewById(R.id.buttonadd);
save.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
name = textName.getText().toString();
sname = textSname.getText().toString();
day = birthDate.getDayOfMonth();
month = birthDate.getMonth()+1;
year = birthDate.getYear();
final String dayStr = String.valueOf(day);
final String monthStr = String.valueOf(month+1);
final String yearStr = String.valueOf(year);
person.setName(name);
person.setSname(sname);
person.setDay(day);
person.setMonth(month);
person.setYear(year);
person.setDateStr(dayStr + "/" + monthStr + "/" + yearStr);
myDB.addBirthday(person);
if(context instanceof MainActivity)
((MainActivity)context).onResume();
dismiss();
}
});
}
}
