How to retrieve saved image from database?

I have created a profile. Now, I can save a profile pic but I don't know how to retrieve an image. I have tried but didn't get any solution?
I have made some changes now after uploading an image when I visit profile again the image view gets invisible. please review my code, where did I have mistake?
I have tried to get image from shared preferences still doesn't work properly...
Here is my code:

here is my xml code
<de.hdodenhof.circleimageview.CircleImageView

android:layout_width="150dp"
android:layout_height="150dp"
android:src="#drawable/useree1"
app:civ_border_width="2dp"
app:civ_border_color="#FF000000"
android:elevation="10dp"
android:scaleType="centerCrop"
android:layout_below="#+id/header_cover_image"
android:layout_centerHorizontal="true"
android:layout_marginTop="-80dp"/>
<de.hdodenhof.circleimageview.CircleImageView

try this way :
SharedPreferences sharedPreferences = getPreferences(MODE_PRIVATE);
String profileImage = sharedPreferences.getString("profile_image", "");
Bitmap bitmap = decodeToBase64(profileImage);
public static Bitmap decodeToBase64(String str) {
byte[] decodedByte = Base64.decode(str, 0);
return BitmapFactory.decodeByteArray(decodedByte, 0, decodedByte.length);
}

I'd recommend the Glide image handling library...
Makes this a lot easier...
https://github.com/bumptech/glide
ImageView imgView = findViewById(R.id.imageview);
Glide
.with(context)
.load(imageBytes)
.centerCrop()
.into(imgView);

How do I make that different button, different imageview will be affected

I'm very new to this coding thing and I hope that anyone of you can help me out on this. Basically I have three different buttons with different image view and I would like to upload them to my MySQL. However when I press all three button at different times, it will only affect the 1 of the image views. Appreciate if you could help.

I think you should change request codes for each gallery intent on each button click.
btnuploadvl.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent gallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(gallery, "request code for btnuploadvl");
}
});
btnuploaddl.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent gallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(gallery, "request code for btnuploaddl");
}
});
btnupadloadnric.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent gallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(gallery, "request code for btnupadloadnric");
}
});
And then check request code detecting which button is clicked on onActivityResult.

image taken from gallery is unable to set in image view

I am taking image from camera as well as from gallery,after getting the image, I want to show the image in imageview.
Image that is captured by camera successfully is shown in imageview but when I want to select it from gallery it does not show the image and it also does not show any error. It was working properly but later I add camera feature in activity, it's not working well.

}
}

selectedImage = BitmapFactory.decodeStream(imageStream);
You should check if selectedImage -the bitmap- is null.
I bet selectedImage==null.
This happens if the bitmap would become too big for available memory.
You should scale it down while loading from stream.
Remember: from the camera you only obtain a thumbnail. Thats the difference.

In your code, try to add createScaledBitmap to resize your photo like this:
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
//add this line and use the new bitmap resized
Bitmap imageBitmapResized = Bitmap.createScaledBitmap(imageBitmap , 120, 120, false);
iv.setImageBitmap(imageBitmapResized );
image = encode(imageBitmapResized );//this line is added to encode
} else if (requestCode == PHOTO_FROM_MEMORY_REQUESTED && resultCode == RESULT_OK) {
updateSelectedPicture(data.getData());
}

Does Service needs another parser?

I have already been fetched data from instagram api. But i cannot reach that data to use it on my service. I have tried all methods that i know.
**Here is my main object: ** If my followers count is increases or decreases, notify, And check that for every 5 min.(I am still working on it. There are lots of misses yet.)
**Here is my main question: ** Do i really have to create a new parser to fetch data that i already have or what should i build?
If you have any sample or Articles for this case, that would be useful.
I heard about Csv file. Is that can be useful to import ?
PS: I learned java and android studio yet. I am pretty newbie.

The only solution that i found is the adding parser to your service to reach data from api. None of the the method can access to reach data from service to activity.
I added this class to reach api data on service.
public void lilParser() throws IOException, JSONException{
URL url = new URL(API_URL + "/users/" + mSession.getId()
+ "/?access_token=" + mAccessToken);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setDoInput(true);
urlConnection.connect();
String response = Utils.streamToString(urlConnection
.getInputStream());
System.out.println(response);
JSONObject jsonObj = (JSONObject) new JSONTokener(response).nextValue();
JSONObject data_obj = jsonObj.getJSONObject("data");
JSONObject counts_obj = data_obj.getJSONObject("counts");
String name = jsonObj.getJSONObject("data").getString("full_name");
String bio =jsonObj.getJSONObject("data").getString("bio");
String counts=jsonObj.getJSONObject("data").getString("counts");
userInfoHashmap.put(TAG_FOLLOWED_BY,counts_obj.getString(TAG_FOLLOWED_BY));
Log.i(TAG,"followedby=>[" + counts + "]");
}
And, Here is my onCreate. You can check The data if it is changed or not.
#Override
public void onCreate() {
Toast.makeText(this,"Service Started", Toast.LENGTH_LONG).show();
myTimer = new Timer();
myTimer.schedule(new TimerTask() {
#Override
public void run() {
String fo = userInfoHashmap.get(TAG_FOLLOWED_BY);
try {
lilParser();
}
catch (IOException e) {e.printStackTrace();}
catch (JSONException e) {e.printStackTrace();}
if(new String(userInfoHashmap.get(TAG_FOLLOWED_BY)).equals(fo)==true){}
else {
getnotification();
}
}
}, 0, 30000);
}
PS: I published my code, that may help someone else. I am still newbie.

Class variable not changing in IF or Switch statements

Seems simple, but I can't get it to work. I have a public class string variable that should change within a if or switch statement. I haven't declared the variable inside the statement so it should change given the scope, no? But it only reads "FROM" and when I do go to change it in the if statement that applies, it does change to "TO" but only in that instance and reverts back to "FROM". I would pass it along the methods, but the full code is more cluttered and I don't think it's possible to do so.
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
String typeOfText = "FROM";
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantRequest) {
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public void onClick(View view) {
if (view.getId() == R.id.faboptions_favorite) {
Toast.makeText(MainActivity.this, "FROM", Toast.LENGTH_SHORT).show();
typeOfText = "FROM";
cameraSource.takePicture(null, new CameraSource.PictureCallback() {
#Override
public void onPictureTaken(byte[] bytes) {
Bitmap bmp = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);
cropPicFile(bmp);
}
});
} else if (view.getId() == R.id.faboptions_textsms) {
Toast.makeText(MainActivity.this, "TO", Toast.LENGTH_SHORT).show();
typeOfText = "TO";
Log.d("VARIABLE","" + typeOfText);
cameraSource.takePicture(null, new CameraSource.PictureCallback() {
#Override
public void onPictureTaken(byte[] bytes) {
Bitmap bmp = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);
cropPicFile(bmp);
}
});
} else {
typeOfText = "FROM";

The reason the code keeps reverting is because the call to readImage() is in onActivityResult() which recreates the activity when called. So basically, you are getting a fresh object, and the onTypeText() is reinitialized. onActivityResult() is basically a callback from your previous activity.

Your onClick() is not being called due you don't assign clicklistener to R.id.faboptions_favorite and the other View
in onCreate add :
findViewById(R.id.faboptions_favorite).setOnClickListener(this);
and same for the other view.
