in my app I need to capture image and show up in imageview and then I will post it to server. But I'm having a problem, the captured image is not showing in imageview. Here is my code:
private void onCaptureImageResult(Intent data) {
Bitmap thumbnail = (Bitmap) Objects.requireNonNull(data.getExtras()).get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
assert thumbnail != null;
thumbnail.compress(Bitmap.CompressFormat.PNG, 90, bytes);
File destination = new File(Environment.getExternalStorageDirectory() + "/storage/emulated/0/Download/"
+ new Date().getTime(), System.currentTimeMillis() + ".png");
FileOutputStream fo;
try {
destination.createNewFile();
fo = new FileOutputStream(destination);
fo.write(bytes.toByteArray());
fo.close();
} catch (IOException e) {
e.printStackTrace();
}
if (photoMekanik) {
imageView.setImageBitmap(thumbnail);
photoMekanik = false;
} else if (photoElektonik) {
imageView2.setImageBitmap(thumbnail);
photoElektonik = false;
}
}
Image is stored, but I want to access directly after capturing the image. What I'm missing here.

Do this to save image. Replace your method with this
public Uri getLocalBitmapUri(ImageView imageView) {
imageview.buildDrawingCache();
Bitmap bm = imageview.getDrawingCache();
OutputStream fOut = null;
Uri outputFileUri;
try {
File root = new File(Environment.getExternalStorageDirectory()
+ File.separator + "folder_name" + File.separator);
root.mkdirs();
File imageFile = new File(root, "myPicName.jpg");
outputFileUri = Uri.fromFile(imageFile);
fOut = new FileOutputStream(imageFile);
} catch (Exception e) {
e.printStackTrace();
}
try {
bm.compress(Bitmap.CompressFormat.PNG, 100, fOut);
fOut.flush();
fOut.close();
return outputFileUri;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
I am building an Android app that takes photos, then uploads them to a Rails API.
The api expects the base64 encoded raw file bytes, to be stored as a temp file representing the image in JPG format.
However, the API is rejecting the uploaded file with this error message:
<Paperclip::Errors::NotIdentifiedByImageMagickError:
This seems to be due to a failure of encoding on the part of the Android app.
The base64 image bytes that I'm sending up look like this:
Which appears invalid just by looking at it.
The image is created in android by taking a pic with the Camera API and base64 encoding the resulting byteArray:
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
Anyone know what I'm doing wrong here?
On button click for capturing an image from a camera use this
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
((Activity) context).startActivityForResult(intent, Constants.REQUEST_IMAGE_CAPTURE);
and on activityResult of the activity implement the following code:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
final ImageView uploadArea = (ImageView) attachmentDialog.findViewById(R.id.uploadArea);
Bitmap bitmap;
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
File f = new File(Environment.getExternalStorageDirectory().toString());
for (File temp : f.listFiles()) {
if (temp.getName().equals("temp.jpg")) {
f = temp;
break;
}
}
try {
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
bitmap = BitmapFactory.decodeFile(f.getAbsolutePath(),
bitmapOptions);
Matrix matrix = new Matrix();
matrix.postRotate(-90);
Bitmap rotatedBitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
rotatedBitmap.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream);
byte[] attachmentBytes = byteArrayOutputStream.toByteArray();
String attachmentData = Base64.encodeToString(attachmentBytes, Base64.DEFAULT);
uploadArea.setImageBitmap(rotatedBitmap);
String path = android.os.Environment
.getExternalStorageDirectory()
+ File.separator
+ "CTSTemp" + File.separator + "default";
f.delete();
OutputStream outFile = null;
File file = new File(path, String.valueOf(System.currentTimeMillis()) + ".jpg");
try {
outFile = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, outFile);
outFile.flush();
outFile.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
I hope this will help you, and for any farther info, please ask
I was Developing an application which will have image on image view .
My need:
What i need is When i click the button then it should store the image that exist in the image view to the sd card(emulator).
Here is how i used:(but no expected results)
Button btnWriteSDFile = (Button) findViewById(R.id.btnWriteSDFile);
btnWriteSDFile.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
ImageView myImage = (ImageView) findViewById(R.id.imageView1);
BitmapDrawable drawable = (BitmapDrawable) myImage.getDrawable();
Bitmap bitmap = drawable.getBitmap();
File sdCardDirectory = Environment.getExternalStorageDirectory();
File image = new File(sdCardDirectory, "image.png");
boolean success = false;
// Encode the file as a PNG image.
FileOutputStream outStream;
try {
outStream = new FileOutputStream(image);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();
success = true;
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
if (success) {
Toast.makeText(getApplicationContext(), "Image saved with success",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(),
"Error during image saving", Toast.LENGTH_LONG).show();
}
}
});
In my above code i didnt get any error
It simply Shows that "save file in mnt/sd/image.png" but no images found.
It would be appreciable if some one helps me to get me out from this rid.
**
"Found out where the exact issues": My program was running perfectly
# 1st time if i click button and check in gallery means there is no
image but once i close and open the emulator then there is a image.But
i need to see the image as soon as updated how to do this any ideas?

Your code looks good, but in order to write something to external storage, you should have the following permission declared in the manifest:
android.permission.WRITE_EXTERNAL_STORAGE
if you use some thing like
ImageView myImage = (ImageView) findViewById(R.id.imageView1);
myImage .setDrawingCacheEnabled(true);
myImage .buildDrawingCache();
Bitmap bitmap = myImage .getDrawingCache();
File sdCardDirectory = Environment.getExternalStorageDirectory();
File image = new File(sdCardDirectory, "image.png");
boolean success = false;
// Encode the file as a PNG image.
FileOutputStream outStream;
try {
outStream = new FileOutputStream(image);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();
success = true;
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
if (success) {
Toast.makeText(getApplicationContext(), "Image saved with success",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(),
"Error during image saving", Toast.LENGTH_LONG).show();
}
}
});
and please set the following permission in androidManifest.xml
android.permission.WRITE_EXTERNAL_STORAGE
Try below code to take a screenshot
private static Bitmap takeScreenShot()
{
Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();
return bitmap;
}
For saving
private File saveBitmap(Bitmap bitmap)
{
File snapShot=null;
try
{
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
File f = new File(Environment.getExternalStorageDirectory()
+ File.separator + "test.jpg");
f.createNewFile();
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
fo.close();
} catch (Exception e)
{
e.printStackTrace();
}
return snapShot;
}
Need to give permission
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
I have an ImageButton, when I press it I can take a picture with my phone. When I take the picture the ImageButtons gets the picture as its source. But the problem is, is that the image doesn't scale down to the dimensions of the ImageButton. It just shows a part of the image in the Imagebutton instead of scaling down. After doing a bit of research I saw you have to use a draw 9 patch. But that is not possible in this case, because the image aren't in my resources, they are made by the user itself.
Can someone help me with this?
My code:
if (requestCode == REQUEST_CAMERA) {
File f = new File(Environment.getExternalStorageDirectory().toString());
for (File temp : f.listFiles()) {
if (temp.getName().equals("temp.jpg")) {
f = temp;
break;
}
}
try {
Bitmap bm;
BitmapFactory.Options btmapOptions = new BitmapFactory.Options();
bm = BitmapFactory.decodeFile(f.getAbsolutePath(),btmapOptions);
// bm = Bitmap.createScaledBitmap(bm, 70, 70, true);
btnImg.setImageBitmap(bm);
String path = android.os.Environment.getExternalStorageDirectory() + File.separator + "Phoenix" + File.separator + "default";
f.delete();
OutputStream fOut = null;
File file = new File(path, String.valueOf(System.currentTimeMillis()) + ".jpg");
try {
fOut = new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
fOut.flush();
fOut.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
else if (requestCode == SELECT_FILE) {
Uri selectedImageUri = data.getData();
String tempPath = getPath(selectedImageUri, MainActivity.this);
Bitmap bm;
BitmapFactory.Options btmapOptions = new BitmapFactory.Options();
bm = BitmapFactory.decodeFile(tempPath, btmapOptions);
btnImg.setImageBitmap(bm);
}
Use ImageView's method setScaleType. Pass ScaleType.CENTER_INSIDE as parameter.
btnImg.setImageBitmap(bm);
btnImg.setScaleType(ScaleType.CENTER_INSIDE);
I am using ImageView in my android application here i show the images from webservice so i am using UrlImageViewHelper. i want to store this image into android Gallery files.
my images like:
String Images = dataExtra.get("images").toString();
System.out.println("image URL"+Images);
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(Images);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
i tried like this.. but its not working. Any one can help me how to store these Images into Android Gallery?
i got solution for this problem, Here my answer
private void saveImagesIntoGallery(){
BitmapDrawable drawable = (BitmapDrawable) imageView.getDrawable();
Bitmap bitmap = drawable.getBitmap();
// File sdCardDirectory = Environment.getExternalStorageDirectory();// its stores under sdcard not in a specific path
String sdCardDirectory = Environment.getExternalStorageDirectory().toString()+"/Pictures/";
String url = arrayForImages[i].toString();
String file = url.substring(url.lastIndexOf('/')+1);
System.out.println("PATH NAME"+sdCardDirectory);
File image = new File(sdCardDirectory, file);
boolean success = false;
// Encode the file as a PNG image.
FileOutputStream outStream;
try {
outStream = new FileOutputStream(image);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream);
/* 100 to keep full quality of the image */
outStream.flush();
outStream.close();
success = true;
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
if (success) {
Toast.makeText(getApplicationContext(), "Image saved with success",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(),
"Error during image saving", Toast.LENGTH_LONG).show();
}
}
Are you sure that the gallery is the best place to store images of webservice?
If you wanted to save to internal storage:
public void saveBitmap(String name, Bitmap bitmap){
if(bitmap!=null && name!=null){
FileOutputStream fos;
if(bitmap!=null){
try {
fos = openFileOutput(name, Context.MODE_PRIVATE);
bitmap.compress(CompressFormat.JPEG, 90, fos);
} catch (FileNotFoundException e) {}
}
}
}
To gallery, i have not examples here. But search a little;)
