I have three Activities
Hobbies
Language
Add Photo
What my goal: I get value of the hobby and language activity and also photo one and send it to the other activity and with that knowledge i create PDF file
Problem since i have 3 activities if user first go to Hobby activity and fill fields and then go to the language activity and fill all fields and at the end user go to the photo activity and fetch the photo from phone media and then create PDF file by doing this way I get the data as well as picture in PDF .Here my code works perfect USER SELECT PHOTO AT THE END AFTER FILLING DATA IN OTHER ACTIVITIES but Problem occur when and if he selects image first and then fills data and create PDF what happens I only get data in my PDF no sign of picture !!
I wanna put all the code but that too much code
Sending picture
private void getting_data_from_fields_and_sending_on_click_listner() {
Intent i = new Intent (Add_Picture_Activity.this , Selecting_Activity.class) ;
ByteArrayOutputStream b = new ByteArrayOutputStream() ;
resultBmp.compress(Bitmap.CompressFormat.JPEG , 100 , b);
byte[] bytes = b.toByteArray();
i.putExtra("UserImage" , bytes);
startActivity(i);
}
receiving Picture
public void gettingInfoFromTheAddPictureActivity() {
bitmap = (Bitmap) getIntent().getParcelableExtra("UserImage");
byte [] bytes = getIntent().getByteArrayExtra("UserImage");
bitmap = BitmapFactory.decodeByteArray(bytes , 0 , bytes.length);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG , 100 , stream);
userImage = null ;
try {
userImage = Image.getInstance(stream.toByteArray());
}catch (Exception c){
}
}
try {
gettingInfoFromTheAddPictureActivity();
userImage.scaleToFit(80 , 80);
userImage.setAbsolutePosition(0,0) ;
p.getDirectContent();
document.add(userImage);
}catch (Exception x){
}
Some How i solved the problem
First i get the path of the user selected image and store it in pref and then use that path to create a bitmap in other activity and then with the bitmap i load image to the PDF File ..
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK){
Uri imageUri = data.getData( );
picturePath = getPath( Add_Picture_Activity.this, imageUri );
Log.d("Picture Path", picturePath);
}else{
Toast.makeText(this, "You have not select image", Toast.LENGTH_SHORT).show();
}
}
public static String getPath(Context context, Uri uri ) {
String result = null;
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = context.getContentResolver( ).query( uri, proj, null, null, null );
if(cursor != null){
if ( cursor.moveToFirst( ) ) {
int column_index = cursor.getColumnIndexOrThrow( proj[0] );
result = cursor.getString( column_index );
}
cursor.close( );
}
if(result == null) {
result = "Not found";
}
return result;
}
private void getting_data_from_fields_and_sending_on_click_listner() {
Intent sendingPicPath = new Intent (Add_Picture_Activity.this , Selecting_Activity.class);
editor = pref.edit() ;
editor.putString("IMAGEPATH" , picturePath);
editor.apply();
startActivity(sendingPicPath);
}
on other activity
String imagePath = user_image.getString("IMAGEPATH" ,"");
Bitmap bitmap = BitmapFactory.decodeFile(imagePath);

I have been making paint app
it has a save option and load, but every time I save another image go to gallery
i want to 'save on save' option too, to load image change and save on it.
the code save:
drawView.setDrawingCacheEnabled(true);
//attempt to save
String ima= MediaStore.Images.Media.insertImage(
getContentResolver(), drawView.getDrawingCache(),
UUID.randomUUID().toString() + ".png", "drawing");
//feedback
if (ima != null) {
Toast savedToast = Toast.makeText(getApplicationContext(),
"Drawing saved to Gallery!", Toast.LENGTH_SHORT);
savedToast.show();
} else {
Toast unsavedToast = Toast.makeText(getApplicationContext(),
"Oops! Image could not be saved.", Toast.LENGTH_SHORT);
unsavedToast.show();
}
drawView.destroyDrawingCache();
}
saveDialog.show();
the load code:
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
saveDialog.show();
}
}
#Override
protected void onActivityResult ( int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
columnIndex = cursor.getColumnIndex(filePathColumn[0]);
temp = cursor.getString(columnIndex);
cursor.close();
a= BitmapFactory.decodeFile(temp);
Drawable d = new BitmapDrawable(getResources(), a);
drawView.setBackgroundColor(Color.WHITE);
drawView.startNew();
drawView.setBackground(d);
Rather than trying to have a save on save method, perhaps try instead of loading a default image you load the image you would like to edit. The file path exists since you are saving them in the drawable area and you are able to access the images in your drawable.
I'm creating a simple app to take a picture. this is my code
Button b1;
ImageView iv;
String TAG = "MAIN ACTIVITY";
File photo;
private Uri mImageUri;
private File createTemporaryFile(String part, String ext) throws Exception {
File externalStorageDirectory = Environment.getExternalStorageDirectory();
File tempDir = new File(externalStorageDirectory + "/cameratest/");
if (!tempDir.exists()) {
tempDir.mkdir();
}
return File.createTempFile(part, ext, tempDir);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b1 = (Button) findViewById(R.id.button);
iv = (ImageView) findViewById(R.id.imageView);
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
try {
// place where to store camera taken picture
photo = createTemporaryFile("picture", ".jpg");
photo.delete();
} catch (Exception e) {
Log.v(TAG, "Can't create file to take picture!");
Toast.makeText(getApplicationContext(), "Please check SD card! Image shot is impossible!",
Toast.LENGTH_SHORT).show();
}
mImageUri = Uri.fromFile(photo);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri);
startActivityForResult(intent, 0);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0 && resultCode == RESULT_OK) {
Log.d(TAG, mImageUri.toString());
Bitmap bitmap = BitmapFactory.decodeFile(mImageUri.toString());
iv.setImageBitmap(bitmap);
}
}
as you can see i've added eLog.d(TAG, mImageUri.toString()); at the end and in the logcat (as well as the FileNotFoundException) i see this direcory:
03-27 00:43:30.498 30526-30526/myapplication.example.falcoleo.cameratest1 D/MAINÂ ACTIVITY: file:///storage/emulated/0/cameratest/picture459838058.jpg
03-27 00:43:30.499 30526-30526/myapplication.example.falcoleo.cameratest1 E/BitmapFactory: Unable to decode stream: java.io.FileNotFoundException: file:/storage/emulated/0/cameratest/picture459838058.jpg: open failed: ENOENT (No such file or directory)
guess if this directory exists?
spoler alert, it does. And it's not like the image is created after the BitmapFactory.decodeFile. I really do not understand what i'm doing wrong. Everything works fine except when it actually has to display the photo, then it just does not display it. just blank. Like WTF m8 i'm just trying to do my job no need to go crazy, you know.
Replace mImageUri.toString() with mImageUri.getPath().
decodeFile expects a path, not an uri string.
file:///storage/emulated/0/cameratest/picture459838058.jpg
Remove file:// because the decodeFile() expects a file system path.
/storage/emulated/0/cameratest/picture459838058.jpg
Use BitmapFactory.decodeStream instead of BitmapFactory.decodeFile.
try ( InputStream is = new URL( file_url ).openStream() ) {
Bitmap bitmap = BitmapFactory.decodeStream( is );
}

Ok for me it was the file path was wrong so I needed to get the real filepath.
First
File file = new File(getPath(uri));
public String getPath (Uri uri)
{
String[] projection = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(uri,
projection,
null,
null,
null);
if (cursor == null)
return null;
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String s = cursor.getString(column_index);
cursor.close();
return s;
}
Then Back To Uri
Uri newUri = Uri.fromFile(file);
This conversion to file and back to uri did the trick for me. I was receiving simple data from action.SEND.
In my costum camera app I need to transfer a bitmap and a Uri from one activity to another. For some reason I'm getting the FAILED BINDER TRANSACTION error on most phones(I get the error on newer phones but don't on Nexus4 and Galaxy3). I get the same error even when I only try to transfer the Bitmap through an intent(I also tried transfering only the Uri and got the error). From what I've read online the error comes from a memory problem but I don't know how to fix it. I would appreciate any kind of help.
My first Activity:
...
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
tv.setVisibility(View.INVISIBLE);
btn.setVisibility(View.INVISIBLE);
selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
img.setImageURI(selectedImageUri);
ok.setVisibility(View.VISIBLE);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}

It is not a memory problem, it's a problem with transferring your image with your intent. You see, Bundle has a limit of how much data it can transfer from one end to the other, currently it's only 1MB. You will problems on all modern phones with a decent camera, as the image exceeds 1MB limit, some old phones with low end camera will work. You need to rethink on how you are going to be transfering the image.
You can
Save it to a file first, send the only the path to it (that's how selecting an image from the gallery works)
Save it to SQL and retrive it on the other end
Make a hodler class with a static variable of image (the most simple)
Make a custom class of Application and put it there for the time being.
Downscale and compress the image before it's transferred
I am developing an application in which i want to capture the image from the camera and display it in another activity in an image view, my problem is that able to capture the image but after capturing i am redirected to first activity instead to second one.
Here is my Code..
PictureOptions.java
public void buttonCameraOpen(View view)
{
// 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);
}
private static Uri getOutputMediaFileUri(int type){
return Uri.fromFile(getOutputMediaFile(type));
}
/** Create a File for saving an image or video */
private static File getOutputMediaFile(int type){
// To be safe, you should check that the SDCard is mounted
// using Environment.getExternalStorageState() before doing this.
File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES), "Easy Heal");
// This location works best if you want the created images to be shared
// between applications and persist after your app has been uninstalled.
// Create the storage directory if it does not exist
if (! mediaStorageDir.exists()){
if (! mediaStorageDir.mkdirs()){
Log.d("MyCameraApp", "failed to create directory");
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
File mediaFile;
if (type == MEDIA_TYPE_IMAGE){
mediaFile = new File(mediaStorageDir.getPath() + File.separator +
"IMG_"+ timeStamp + ".jpg");
} else {
return null;
}
return mediaFile;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Bitmap selectedphoto = null;
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE && resultCode == RESULT_OK && null!=data) {
// Image captured and saved to fileUri specified in the Intent
//selectedphoto = (Bitmap) data.getExtras().get("data");
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 filePath = cursor.getString(columnIndex);
File f =new File(filePath);
String filename = f.getName();
cursor.close();
selectedphoto = BitmapFactory.decodeFile(filePath);
Intent intent = new Intent(PictureOptions.this,ShowImage.class);
//intent.putExtra("data", selectedphoto);
intent.setData( selectedImage );
startActivity(intent);
} else if (resultCode == RESULT_CANCELED) {
// User cancelled the image capture
} else {
// Image capture failed, advise user
}
}

imageview.setImageURI(imageUri);
}

I finally found an awesome solution
This library is used to capture image from camera or select from gallery and return back image in File format in onActivityResult method, which can be used further in the application.
Use
EasyImage Library
Uri uriSavedImage=Uri.fromFile(new File("/sdcard/flashCropped.png"));
camera.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(camera, 1);
After clicking the image, check whether it exists or not. Then send the path to the image file to the next activity and display it via Bitmap.
Call the camera intent
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
then on activity for result use this
'case REQUEST_IMAGE_CAPTURE:
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
saveBitmap(imageBitmap);
mimageView1.setImageBitmap(imageBitmap);
mIntent.putExtra("ACTIVITY_CODE", 1);
startActivity(mIntent);
break;
the add this method in ur same class
public void saveBitmap(Bitmap bmp)
{
String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() +"/DCIM";
try
{
File dir = new File(file_path);
if(!dir.exists())
dir.mkdirs();
File file = new File(dir, "time");
cameraUrl=file.getAbsolutePath();
FileOutputStream fOut = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.PNG, 100, fOut);
fOut.flush();
fOut.close();
}
catch (Exception e) {
Log.e("errr in ","inserting the image at parictular location");
}
}
then call this in ur another activity where u want the image
String valueC = getIntent().getExtras().getString("CAMERA");
Log.v("imageBitmap", ""+valueC);
Bitmap yourSelectedImageC = BitmapFactory.decodeFile(valueC);
mImgV_image.setImageBitmap(yourSelectedImageC);
I have same problem after spending 2 days finally i got the anwer
First activity
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK && data != null) {
Uri uri = data.getData();
Intent intent= new Intent(this,SecondActivity.class);
selfiSrc.putExtra("imgurl", uri );
startActivity(intent);
}
SecondActivity
Imageview iv_photo=(ImageView)findViewById(R.id.iv_photo);
Bundle extras= getIntent().getExtras();
if(extras!=null)
{
path = (Uri) extras.get("imgurl");
iv_photo.setImageURI(path);
}
Another way see my answer
Android - how can i transfer ImageView from one activity to another activity?
I am new to Android. I have just created an AVD with 256 MB android-SDcard in it in Android 2.1. And I have inserted two images into it. I have done this using the DDMS perspective. And the images are now stored into a folder 100ANDRO in the DCIM folder of SDcard. Now I want to create an application that allows the user to select the images through browsing the folders and need to save the corresponding image to the database android-sqlite.
Can someone help me to find an appropriate method for this? Thanks in advance.
I have found one method for this.
I have created a button for UPLOAD and on the click action I have set like this.
upload.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v) {
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, 1);
}
});
And I have overrided this method along with the same class as below.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 1:
{
if (resultCode == RESULT_OK)
{
Uri photoUri = data.getData();
if (photoUri != null)
{
try {
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(photoUri, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = cursor.getString(columnIndex);
cursor.close();
Bitmap bitmap = BitmapFactory.decodeFile(filePath);
imgView.setImageBitmap(bitmap);
int size = bitmap.getWidth() * bitmap.getHeight();
ByteArrayOutputStream out = new ByteArrayOutputStream(size);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
try {
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();}
String bb = out.toString();
byte[] x = out.toByteArray();
image_value.setTag(x);
image_value.setText(filePath);
}catch(Exception e)
{}
}
}
}
Here image_value represents a hidden text view in the xml file.
I have passed the value of the image location and bytes as text view's value and tag.
And later on I have saved this bytes into the database for later display. Its working fine.
Thanks to all.
