Store image location after cropping into the app folder in android

Store image location after cropping into the app folder in android - android

I have an activity in which when a user clicks the ImageView a dialog appears and he can choose pick from gallery or camera. I was a success in writing all the code and was able to replace the ImageView with the new image. I have converted the image in base64 and stored the image in shared preference. Is there is any way to store the image location after cropping in the shared preference I have added my code here? Thank you in Advance

Camera is giving very big size image on device

In my project, I am capturing image from the camera. I am taking the full-size image from the app (instead of taking thumbnail). Captured image is of very big size which is 7 to 18 mb. When I have taken image from my default camera app, the size was roughly 2.5 mb only. As well as it's taking lot of time(6-10 seconds) to load and save to the folder. This happening only when I am using the android device, on emulator it's working good. This is my code:

Something you could do is download an available API online, or, if need be, dowload the source code of some online compressor. Then you could use it as a model. Never directly use the source code. One that is widely supported across languages is: https://optimus.keycdn.com/support/image-compression-api/

I am taking the image from the camera and getting the File. So, I am saving the image directly in file location which I generated using getOutputMediaFile() method. For that I am overloading saveImage() method like this:
private void saveImage(File mediaImage) {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(mediaImage);
mediaScanIntent.setData(contentUri);
getContext().sendBroadcast(mediaScanIntent);
}
This method will put the image in the desired file location and also accessible to the Gallery for other apps. This method is same as galleryAddPic() method on this link Taking Photos Simply
But In the case of picking a photo from the Gallery, I will have to create the File in the desired location and write the bytes of the picked image into that file, so the old saveImage() method will not change.
In onActivityResult method, this is how I used overloaded saveImage() method:
else if (requestCode == CAMERA) {
saveImage(imageFile);
Bitmap bitmap = BitmapFactory.decodeFile(imageFile.getAbsolutePath());
loadImage.setImageBitmap(bitmap);
Toast.makeText(getContext(), MESSAGE_IMAGE_SAVED, Toast.LENGTH_SHORT).show();
imageTextMessage.setVisibility(View.INVISIBLE);
}

How to select an image from the gallery and convert it to Base64? [duplicate]

sorry for asking silly question.but it solved yet my me.please help i had tried all codes on stackoverflow and follow other tutorial but it wont help at all.i am taking image from galary and convert to base64 it works perfectly fine when taking image on camera but why it dont work on galary i dont know please help me.;(
This is the code to select the image
private void selectImage() {
final CharSequence[] items = { "Take Photo", "Choose from Library",
"Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(TestFragment.this);
builder.setTitle("Add Photo!");
builder.setItems(items, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
boolean result= Utility.checkPermission(TestFragment.this);
if (items[item].equals("Take Photo")) {
userChoosenTask ="Take Photo";
if(result)
cameraIntent();
} else if (items[item].equals("Choose from Library")) {
userChoosenTask ="Choose from Library";
if(result)
galleryIntent();
} else if (items[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}
After this
private void galleryIntent()
{
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);//
startActivityForResult(Intent.createChooser(intent, "Select File"),SELECT_FILE);
}
private void cameraIntent()
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == SELECT_FILE)
onSelectFromGalleryResult(data);
else if (requestCode == REQUEST_CAMERA)
onCaptureImageResult(data);
}
}
private void onCaptureImageResult(Intent data) {
bitmap = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
File destination = new File(Environment.getExternalStorageDirectory(),
System.currentTimeMillis() + ".jpg");
FileOutputStream fo;
try {
destination.createNewFile();
fo = new FileOutputStream(destination);
fo.write(bytes.toByteArray());
fo.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
imgvcomp.setImageBitmap(bitmap);
String img=getStringImage(bitmap);
Log.v(TAG,"base64"+img);//perfectly string base64 to image
}
#SuppressWarnings("deprecation")
private void onSelectFromGalleryResult(Intent data) {
if (data != null) {
try {
bitmap = MediaStore.Images.Media.getBitmap(getApplicationContext().getContentResolver(), data.getData());
} catch (IOException e) {
e.printStackTrace();
}
}
imgvcomp.setImageBitmap(bitmap);
String img=getStringImage(bitmap);
Log.v(TAG,"base64"+img);//checking in log base64 string to image cropeed image found
}
public String getStringImage(Bitmap bmp){
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 90, baos);
byte[] imageBytes = baos.toByteArray();
String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);
return encodedImage;
}
private void showToastMessage(String message) {
Log.v(TAG, String.format("showToastMessage :: message = %s", message));
// Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG).show();
}
why i found the cropped image after selecting from galary?there is no error in error log here is the logcat

You can use following code:
public static String encodeTobase64(Bitmap image) {
Bitmap immagex=image;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
immagex.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] b = baos.toByteArray();
String imageEncoded = Base64.encodeToString(b,Base64.DEFAULT);
Log.e("LOOK", imageEncoded);
return imageEncoded;
}
Use below code in onActivityResult()
InputStream imageStream = null;
try {
imageStream = this.getContentResolver().openInputStream(selectedImage);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Bitmap yourSelectedImage = BitmapFactory.decodeStream(imageStream);
encodeTobase64(yourSelectedImage);

Try this...
public String getStringImage(Bitmap bmp){
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);
return encodedImage;
}

Here is a similar code. I have implemented the same thing in my app. You can select images from either gallery or camera and You can convert it as a base 64. Try this Its working for me. Hope it work for you too

This is how I do it on my onActivityResult of my gallery intent.
String imagePath = ImageUtil.getRealPathFromURI(getActivity(), data.getData());
Then converting the whole thing to bitmap.
Bitmap bitmap = BitmapFactory.decodeFile(imagePath);
Here is my getRealPathFromURI method from ImageUtil Class.
public static String getRealPathFromURI(Context context, Uri contentURI) {
String result = null;
String[] projection = {MediaStore.Images.Media.DATA};
try {
Cursor cursor = context.getContentResolver().query(contentURI, projection, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(projection[0]);
result = cursor.getString(columnIndex);
cursor.close();
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
And here is my conversion from bitmap to base64.
public static String getBase64(Bitmap bitmap) {
if (bitmap != null) {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
return Base64.encodeToString(baos.toByteArray(), Base64.DEFAULT);
}
return null;
}

calling another class functions from one class on button click in android

I am making an app with various activities and each activity uses the camera function which is defined in another class. I want that in each activity when the camera button is clicked the camera class is called.
This is my main class:-
package com.example.ishan.complainbox;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import java.lang.String;
public class Crime extends MainActivity implements View.OnClickListener
{
camera cam=new camera();
EditText str,city,pn,det;
Button save,pic;
crimeDBHandler dbHandler;
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_crime);
// Get References of Views
str = (EditText) findViewById(R.id.str);
city = (EditText) findViewById(R.id.city);
pn = (EditText) findViewById(R.id.pin);
det = (EditText) findViewById(R.id.detail);
save = (Button) findViewById(R.id.save);
pic=(Button) findViewById(R.id.uploadpic);
dbHandler = new crimeDBHandler(this, null, null, 1);
}
public void onClick(View view) {
String street = str.getText().toString();
String cty = city.getText().toString();
String pin = pn.getText().toString();
String detail = det.getText().toString();
// check if any of the fields are vaccant
if(str.equals("")||city.equals("")||pn.equals("")||det.equals(""))
{
Toast.makeText(getApplicationContext(), "Field Vacant",
Toast.LENGTH_LONG).show();
return;
}
// check if both passwords match
else
{
// Save the Data in Database
dbHandler.insertEntry(street,cty,pin,detail);
Toast.makeText(getApplicationContext(), "Complaint Successfully
Filed ", Toast.LENGTH_LONG).show();
}
}
};
.....and this is the camera class..:-
package com.example.ishan.complainbox;

This can be achieved through regular inter-activity communication mechanisms like passing intents or using broadcast receivers. I would suggest using intents - Refer this basic example from Android doc: https://developer.android.com/training/basics/firstapp/starting-activity.html
EDIT
Response to OP's question in comment-
You have to save the image file to FS in your Camera Class and pass the file name as an Extra with the intent to your Crime class. Since you are dealing with storage your Apps's manifest now would need additional permissions. I would recommend you go through this thread: Camera is not saving after taking picture

Take image from gallery and convert to base64 issue

sorry for asking silly question.but it solved yet my me.please help i had tried all codes on stackoverflow and follow other tutorial but it wont help at all.i am taking image from galary and convert to base64 it works perfectly fine when taking image on camera but why it dont work on galary i dont know please help me.;(
This is the code to select the image
private void selectImage() {
final CharSequence[] items = { "Take Photo", "Choose from Library",
"Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(TestFragment.this);
builder.setTitle("Add Photo!");
builder.setItems(items, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
boolean result= Utility.checkPermission(TestFragment.this);
if (items[item].equals("Take Photo")) {
userChoosenTask ="Take Photo";
if(result)
cameraIntent();
} else if (items[item].equals("Choose from Library")) {
userChoosenTask ="Choose from Library";
if(result)
galleryIntent();
} else if (items[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}
After this
private void galleryIntent()
{
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);//
startActivityForResult(Intent.createChooser(intent, "Select File"),SELECT_FILE);
}
private void cameraIntent()
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);
}

if (resultCode == Activity.RESULT_OK) {
if (requestCode == SELECT_FILE)
onSelectFromGalleryResult(data);
else if (requestCode == REQUEST_CAMERA)
onCaptureImageResult(data);
}
}
private void onCaptureImageResult(Intent data) {
bitmap = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
File destination = new File(Environment.getExternalStorageDirectory(),
System.currentTimeMillis() + ".jpg");
FileOutputStream fo;
try {
destination.createNewFile();
fo = new FileOutputStream(destination);
fo.write(bytes.toByteArray());
fo.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
imgvcomp.setImageBitmap(bitmap);
String img=getStringImage(bitmap);
Log.v(TAG,"base64"+img);//perfectly string base64 to image
}
#SuppressWarnings("deprecation")
private void onSelectFromGalleryResult(Intent data) {
if (data != null) {
try {
bitmap = MediaStore.Images.Media.getBitmap(getApplicationContext().getContentResolver(), data.getData());
} catch (IOException e) {
e.printStackTrace();
}
}
imgvcomp.setImageBitmap(bitmap);
String img=getStringImage(bitmap);
Log.v(TAG,"base64"+img);//checking in log base64 string to image cropeed image found
}
public String getStringImage(Bitmap bmp){
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 90, baos);
byte[] imageBytes = baos.toByteArray();
String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);
return encodedImage;
}
private void showToastMessage(String message) {
Log.v(TAG, String.format("showToastMessage :: message = %s", message));
// Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG).show();
}
why i found the cropped image after selecting from galary?there is no error in error log here is the logcat

You can use following code:
public static String encodeTobase64(Bitmap image) {
Bitmap immagex=image;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
immagex.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] b = baos.toByteArray();
String imageEncoded = Base64.encodeToString(b,Base64.DEFAULT);
Log.e("LOOK", imageEncoded);
return imageEncoded;
}
Use below code in onActivityResult()
InputStream imageStream = null;
try {
imageStream = this.getContentResolver().openInputStream(selectedImage);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Bitmap yourSelectedImage = BitmapFactory.decodeStream(imageStream);
encodeTobase64(yourSelectedImage);

Try this...
public String getStringImage(Bitmap bmp){
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);
return encodedImage;
}

Here is a similar code. I have implemented the same thing in my app. You can select images from either gallery or camera and You can convert it as a base 64. Try this Its working for me. Hope it work for you too

}

This is how I do it on my onActivityResult of my gallery intent.
String imagePath = ImageUtil.getRealPathFromURI(getActivity(), data.getData());
Then converting the whole thing to bitmap.
Bitmap bitmap = BitmapFactory.decodeFile(imagePath);
Here is my getRealPathFromURI method from ImageUtil Class.
public static String getRealPathFromURI(Context context, Uri contentURI) {
String result = null;
String[] projection = {MediaStore.Images.Media.DATA};
try {
Cursor cursor = context.getContentResolver().query(contentURI, projection, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(projection[0]);
result = cursor.getString(columnIndex);
cursor.close();
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
And here is my conversion from bitmap to base64.
public static String getBase64(Bitmap bitmap) {
if (bitmap != null) {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
return Base64.encodeToString(baos.toByteArray(), Base64.DEFAULT);
}
return null;
}

Problems when loading cameraimages in imageView

When I take a picture, the picture will saved on the SD.(This works very well)
But the picture won´t shows in the imageView. Do you have any idea?

public class Cam extends Activity {
private Uri fileUri;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.b_cam);
Button button2 = (Button) findViewById(R.id.photo);
button2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Start ActivityTwo
/*
* Intent intent = new Intent(getApplicationContext(),

*/
try {
PackageManager packageManager = getPackageManager();
boolean doesHaveCamera = packageManager
.hasSystemFeature(PackageManager.FEATURE_CAMERA);
if (doesHaveCamera) {
// start the image capture Intent
Intent intent = new Intent(
MediaStore.ACTION_IMAGE_CAPTURE);
// Get our fileURI
fileUri = getOutputMediaFile();
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(intent, 100);
}
} catch (Exception ex) {
Toast.makeText(getApplicationContext(),
"There was an error with the camera.",
Toast.LENGTH_LONG).show();
}
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
if (requestCode == 100) {
if (resultCode == RESULT_OK) {
if (intent == null) {
// The picture was taken but not returned
Toast.makeText(
getApplicationContext(),
"The picture was taken and is located here: "
+ fileUri.toString(), Toast.LENGTH_LONG)
.show();
}else {
// The picture was returned
Bundle extras = intent.getExtras();
ImageView imageView1 = (ImageView) findViewById(R.id.imageView1);
imageView1.setImageBitmap((Bitmap) extras.get("data"));
}
}
}
}
private Uri getOutputMediaFile() throws IOException {
File mediaStorageDir = new File(
Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
"DayTwentyNine");
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss")
.format(new Date());
File mediaFile;
mediaFile = new File(mediaStorageDir.getPath() + File.separator
+ "IMG_" + timeStamp + ".jpg");
if (mediaFile.exists() == false) {
mediaFile.getParentFile().mkdirs();
mediaFile.createNewFile();
}
return Uri.fromFile(mediaFile);
}
}
In the manifest I have are the following:
uses-feature android:name="android.hardware.camera" android:required="false"
uses-permission android:name="android.permission.CAMERA"
uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"

Here I have this peace of code that works fine the first function open the camera and take the picture and the second one place the image you took into an image view...
public void takePictu(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data){
if(requestCode == CAMERA_REQUEST && resultCode == RESULT_OK){
photo3 = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo3);
imageView.buildDrawingCache();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
photo3.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bm is the bitmap object
byte[] b = baos.toByteArray();
encodedImage = android.util.Base64.encodeToString(b, android.util.Base64.DEFAULT);
}
}
