I have developed a camera application with default camera. This application works in all other Android phones but some problem with Samsung Galaxy S
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
This code is giving a result and I am getting a bitmap image. But I couldn't retrieve an image path from this.
When I give EXTRA_OUTPUT, Galaxy S returning a null value. So that I couldn't define file path and name before calling camera intent. When we take picture using this application, Galaxy S is saving this picture in default location and not saving to pre defined location.
If anybody has solution for this, please help me.
What I've done for this is define a location for EXTRA_OUTPUT as a Uri, cache that in a static or member variable, and then in onActivity result use the cached location to retrieve the image. I had the same problem you were describing, and this seems to work fine. The only drawback is having 2 copies of the image, one in the location you defined in EXTRA_OUTPUT, and one in the default location.
Found answer here is the best example which is it self bothering about the device!

I have 3 activities say A, B and C.
A calls B.
When B doesn't call C it returns to A. But when B calls C it doesn't return to A, the app stops.
Now the real problem is, from activity A I want to call an image picker and crop the image. That's Activity B which crops and calls C for picking image.
Activity A:
iv_profile_pic.setOnClickListener(new View.OnClickListener() {//iv_profile_pic is an ImageView
#Override
public void onClick(View view) {
Intent i=new Intent(MainActivity.this,profile_pic_chooser.class);
i.setFlags(0);
MainActivity.this.startActivityForResult(i, 999);
Toast.makeText(getApplicationContext(),"Reached",Toast.LENGTH_SHORT).show();
}
});
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == 999) {
Bitmap image=data.getParcelableExtra("picture");
iv_profile_pic.setImageBitmap(image);
}
}
Activity B:
It has 2 buttons. Load and Crop. Load when clicked calls ImageChooserIntent and chooses an image which is opened in B with guidlines to crop.
Crop when clicked should return back to A the cropped image.
If crop is called without calling load, it returns to A with null, of-course.
But if Load is clicked first and then Crop is called, the app simply stops.
public void onLoadImageClick(View view) {
startActivityForResult(getPickImageChooserIntent(), 200);
}
public void onCropImageClick(View view) {
Bitmap cropped = mCropImageView.getCroppedImage(500, 500);
if (cropped != null) {
mCropImageView.setImageBitmap(cropped);
iv.setImageBitmap(cropped);
Intent returnIntent = new Intent();
returnIntent.putExtra("picture", cropped);
setResult(Activity.RESULT_OK, returnIntent);
finish();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK) {
Uri imageUri = getPickImageResultUri(data);
// For API >= 23 we need to check specifically that we have permissions to read external storage,
// but we don't know if we need to for the URI so the simplest is to try open the stream and see if we get error.
boolean requirePermissions = false;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M &&
checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED &&
isUriRequiresPermissions(imageUri)) {
// request permissions and handle the result in onRequestPermissionsResult()
requirePermissions = true;
mCropImageUri = imageUri;
requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, 0);
}
if (!requirePermissions) {
mCropImageView.setImageUriAsync(imageUri);
}
}
}
I got a workaround. The most probable problem I was facing was:
I was using an external library for cropping the image. This library did 2 things.
First, selected an image using imageChooser intent.
Second, Cropped that image.
After the library cropped the image, it wasn't saving the cropped image in local/external storage. But I was trying to pass it back to parent directory.
There's the problem. The file doesn't exist and still I am trying to use it. The application terminates.
So my workaround was,
• Save the bitmap in storage
• Pass the Uri to parent
• Extract that Uri from child
• Make bitmap from that Uri
• Apply on the ImageView
So Activity B had:
public void onCropImageClick(View view) {
Bitmap cropped = mCropImageView.getCroppedImage(500, 500);
if (cropped != null) {
mCropImageView.setImageBitmap(cropped);
iv.setImageBitmap(cropped);
File externalStorageDirectory = Environment.getExternalStorageDirectory();
externalStorageDirectory= new File(externalStorageDirectory , "FOLDERNAME");
if(!createDirIfNotExists(externalStorageDirectory)){
Toast.makeText(this,"Failed creating Directory!",Toast.LENGTH_SHORT).show();
}else{
File filename=new File(externalStorageDirectory, String.valueOf(Calendar.getInstance().getTimeInMillis())+".PNG");
FileOutputStream out = null;
try {
out = new FileOutputStream(filename);
cropped.compress(Bitmap.CompressFormat.PNG, 100, out); // cropped is your Bitmap instance
// PNG is a lossless format, the compression factor (100) is ignored
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
Intent returnIntent = new Intent();
returnIntent.putExtra("picture", Uri.fromFile(filename));
setResult(RESULT_OK, returnIntent);
finish();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
//Toast.makeText(this,mCropImageUri.toString(),Toast.LENGTH_SHORT).show();
}
And Activity A had:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == 999 && resultCode==RESULT_OK) {
Uri path=data.getParcelableExtra("picture");
Bitmap bitmap=null;
try {
bitmap= MediaStore.Images.Media.getBitmap(this.getContentResolver(), path);
} catch (IOException e) {
e.printStackTrace();
}
Toast.makeText(this,path.toString(),Toast.LENGTH_SHORT).show();
if (bitmap!=null){
iv_profile_pic.setImageBitmap(bitmap);
}
}
Maybe my problem statement is wrong, but workaround works. Any edits/suggestions
are 100% welcome. Just in-case someone like me gets stuck, this might help!
I am attempting to take a captured image and display to the Activity. When the image is set, it gets rotated to the right 90 degrees. I'm not sure what I am doing wrong. I capture the image by using MediaStore.ACTION_IMAGE_CAPTURE and saved it and set it with a URI. Here's the code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_selectusername);
confirm = (Button) findViewById(R.id.confirm_select);
confirm.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
takePhoto();
}
});
}
private void takePhoto() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File photo = new File(Environment.getExternalStorageDirectory(), "temp.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
//This is for photo editing purposes
inputURI = Uri.fromFile(photo);
outputURI = Uri.fromFile(new File(getCacheDir(), photoname));
//Cropping, Resizing, etc. takes place
startActivityForResult(intent, TAKE_PICTURE);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent result) {
super.onActivityResult(requestCode, resultCode, result);
if(requestCode == TAKE_PICTURE && resultCode == RESULT_OK){
ImageView imageView = (ImageView) findViewById(R.id.profilepicture_select);
imageView.setImageURI(outputURI);
}else{
Log.d("TEST", "Something went wrong!");
}
}
I can show more code and clarify if necessary. All Help is appreciated!
Your code looks fine. It's likely a problem with the device's camera. This is a known issue for the Galaxy S4. Some devices output strange exif data which results in the image being off when you display it. How do you fix it?
Here's a lead for you:
Android camera/picture orientation issues with Samsung Galaxy S3, S4, S5
I am displaying image from the sdcard. I searched a lot in google and got the following code
I have a button, on click of that I am calling camera feature.
public void onClick(View arg0) {
// create intent with ACTION_IMAGE_CAPTURE action
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File photo = new File(Environment.getExternalStorageDirectory(), "Pic.jpg");
photoPath = Uri.fromFile(photo);
intent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(photo));
System.out.println(photoPath);
startActivityForResult(intent, TAKE_PICTURE);
}
and I have wriiten following code in onActivityResult function.
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (requestCode == TAKE_PICTURE && resultCode == RESULT_OK) {
System.out.println("after activity"+photoPath);
Uri selectedImage = photoPath;
getContentResolver().notifyChange(selectedImage, null);
ivThumbnailPhoto = (ImageView) findViewById(R.id.ivThumbnailPhoto);
ContentResolver cr = getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media
.getBitmap(cr, selectedImage);
ivThumbnailPhoto.setImageBitmap(bitmap);
Toast.makeText(this, selectedImage.toString(),
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
.show();
Log.e("Camera", e.toString());
}
}
}
Problem is I am getting photoPath value as null and it ends up with nullpointer exception. Please help me to find out issue.
Thanks in advance
You are passing a value of file path as intent extra, this is the correct behavior.
intent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(photo));//here save this uri you are passing as extra.
in onActivityResult, if RESULT_CODE is OK use above URI which you passed in as EXTRA_OUTPUT, you will get null intent/data from camera, so don't use it.
EDIT:- as you are going out of activity and coming back there can be chances of your PhotoPath variable to become NULL, you have two solution here.
1) Make photopath/uri static.
2) Use below code to save it when going out and get the value when coming into the activity.
/**
* Here we store the file url as it will be null after returning from camera
* app
*/
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
// save file url in bundle as it will be null on scren orientation
// changes
outState.putParcelable("file_uri", photopath);
}
/*
* Here we restore the fileUri again
*/
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
// get the path
photoPath = savedInstanceState.getParcelable("file_uri");
}
I have an app published and one of the fundamental features is to allow the user to take a picture, and then save that photo in a specific folder on their External Storage.
Everything seems to be working fine, but I've gotten two reports now that claim that after taking a photo, and clicking "Done" to exit the camera (and return back to the Activity), the app is Forced Closed, bringing the user back to the home screen.
This happens on a Samsung Nexus S and the Galaxy Tab. Below I've posted my code to show I set up my intent and how I handle saving and displaying the photo in onActivityResult(). Any guidance on what might be causing it to crash after they click "Done" to exit the camera app, would be greatly appreciated!
Again, this seems to be working fine on most devices but I was wondering if their is a more efficient, universal approach I should be taking. Thank you
How I'm firing the Camera Intent
case ACTION_BAR_CAMERA:
// numbered image name
fileName = "image_" + String.valueOf(numImages) + ".jpg";
output = new File(direct + File.separator + fileName); // create
// output
while (output.exists()) { // while the file exists
numImages++; // increment number of images
fileName = "image_" + String.valueOf(numImages) + ".jpg";
output = new File(outputFolder, fileName);
}
camera = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
uriSavedImage = Uri.fromFile(output); // get Uri of the output
camera.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage); //pass in Uri to camera intent
startActivityForResult(camera, 1);
break;
default:
return super.onHandleActionBarItemClick(item, position);
}
return true;
}
How I'm setting up onActivityResult()
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) { // If data was passed successfully
Bundle extras = data.getExtras();
//Bundle extras = data.getBundleExtra(MediaStore.EXTRA_OUTPUT);
/*ad = new AlertDialog.Builder(this).create();
ad.setIcon(android.R.drawable.ic_menu_camera);
ad.setTitle("Save Image");
ad.setMessage("Save This Image To Album?");
ad.setButton("Ok", this);
ad.show();*/
bmp = (Bitmap) extras.get("data"); // Set the bitmap to the bundle
// of data that was just
// received
image.setImageBitmap(bmp); // Set imageview to image that was
// captured
image.setScaleType(ScaleType.FIT_XY);
}
}
First lets make it clear - we have two options to take image data in onActivityResult from Camera:
1. Start Camera by passing the exact location Uri of image where you want to save.
2. Just Start Camera don't pass any Loaction Uri.
1 . IN FIRST CASE :
Start Camera by passing image Uri where you want to save:
String imageFilePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/picture.jpg";
File imageFile = new File(imageFilePath);
Uri imageFileUri = Uri.fromFile(imageFile); // convert path to Uri
Intent it = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
it.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, imageFileUri);
startActivityForResult(it, CAMERA_RESULT);
In onActivityResult receive the image as:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (RESULT_OK == resultCode) {
iv = (ImageView) findViewById(R.id.ReturnedImageView);
// Decode it for real
BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
bmpFactoryOptions.inJustDecodeBounds = false;
//imageFilePath image path which you pass with intent
Bitmap bmp = BitmapFactory.decodeFile(imageFilePath, bmpFactoryOptions);
// Display it
iv.setImageBitmap(bmp);
}
}
2 . IN SECOND CASE:
Start Camera without passing image Uri, if you want to receive image in Intent(data) :
Intent it = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(it, CAMERA_RESULT);
In onActivityResult recive image as:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (RESULT_OK == resultCode) {
// Get Extra from the intent
Bundle extras = data.getExtras();
// Get the returned image from extra
Bitmap bmp = (Bitmap) extras.get("data");
iv = (ImageView) findViewById(R.id.ReturnedImageView);
iv.setImageBitmap(bmp);
}
}
*****Happy Coding!!!!*****
On the camera button click event you can try this:
final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(getTempFile(this)));
startActivityForResult(intent, TAKE_PHOTO_CODE);
declare TAKE_PHOTO_CODE globally as:
private static final int TAKE_PHOTO_CODE = 1;
Add getTempFile Function in the code which will help to save the image named myImage.png you clicked in the sdcard under the folder named as your app's package name.
private File getTempFile(Context context) {
final File path = new File(Environment.getExternalStorageDirectory(),
context.getPackageName());
if (!path.exists()) {
path.mkdir();
}
return new File(path, "myImage.png");
}
Now on OnActivityResult function add this:
if (requestCode == TAKE_PHOTO_CODE) {
final File file = getTempFile(this);
try {
Uri uri = Uri.fromFile(file);
Bitmap captureBmp = Media.getBitmap(getContentResolver(),
uri);
image.setImageBitmap(captureBmp);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
in case you get Memory issues than add below code:
#Override
protected void onPause() {
image.setImageURI(null);
super.onPause();
}
I hope this will help you
I suspect 3 posible problems may have created your issue:
Some devices return null when you call extras.get("data"); in onActivityResult method so your problem may be a NullPointerException. To solve this, you need to pass the exact URI location to tell the camera app where you want it to store and use it in onActivityResult to retrieve the image as a Bitmap.
Some other devices return a full size Bitmap when extras.get("data"); in onActivityResult. If the bitmap is too large that can result in an OutOfMemmoryError, so maybe you need to decode your image in a smaller size to not take so much memmory heap. This two links can help you in this situation:
http://developer.android.com/training/displaying-bitmaps/load-bitmap.html
BitmapFactory OOM driving me nuts
Maybe your activity is destroyed by the GC so you have to use onSavedInstanceState and onRestoreInstanceState to save your Activity's data. See the answer of this previous post for more information.
I don't know if you already have dealt with these issues.
Hope that helps:)
First, make sure to check request code, you might be catching someone else's result there. Second, don't use the intent's data Bitmap - if anything, it's small, but since you provide the path to store captured image, it shouldn't even be there (see here). So, store the url you provided as output file path and read Bitmap from there when you've received RESULT_OK for your request:
...
// save your file uri, not necessarily static
mUriSavedImage = Uri.fromFile(output);
startActivityForResult(camera, MY_REQUEST_CODE);
/* Make a String like "com.myname.MY_REQUEST_CODE" and hash it into int to give it
a bit of uniqueness */
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
Bitmap bmp = BitmapFactory.decodeFile(mUriSavedImage);
if (bmp != null) {
image.setImageBitmap(bmp); // Set imageview to image that was
// captured
image.setScaleType(ScaleType.FIT_XY);
} else {
Toast.makeText(this, "Something went wrong", Toast.LENGTH_SHORT).show();
}
}
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}
For Samsung devices add below one line in your AndroidManifest.xml File
android:configChanges="orientation|screenSize"
i hope this will work for you
I faced the same issue. Apparently the fix is to make the uriSavedImage as static. Not sure if this is the best way. But this works for me.
Follow the steps given on this link. Hope this is useful for you.
OR
Fetching Your Image Without Crashing
Write the below code in MainActivity
// Storage for camera image URI components
private final static String CAPTURED_PHOTO_PATH_KEY = "mCurrentPhotoPath";
private final static String CAPTURED_PHOTO_URI_KEY = "mCapturedImageURI";
// Required for camera operations in order to save the image file on resume.
private String mCurrentPhotoPath = null;
private Uri mCapturedImageURI = null;
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
if (mCurrentPhotoPath != null) {
savedInstanceState.putString(CAPTURED_PHOTO_PATH_KEY, mCurrentPhotoPath);
}
if (mCapturedImageURI != null) {
savedInstanceState.putString(CAPTURED_PHOTO_URI_KEY, mCapturedImageURI.toString());
}
super.onSaveInstanceState(savedInstanceState);
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
if (savedInstanceState.containsKey(CAPTURED_PHOTO_PATH_KEY)) {
mCurrentPhotoPath = savedInstanceState.getString(CAPTURED_PHOTO_PATH_KEY);
}
if (savedInstanceState.containsKey(CAPTURED_PHOTO_URI_KEY)) {
mCapturedImageURI = Uri.parse(savedInstanceState.getString(CAPTURED_PHOTO_URI_KEY));
}
super.onRestoreInstanceState(savedInstanceState);
}

I have a problem on my Android app. I'm using MediaStore.ACTION_IMAGE_CAPTURE intent to take picture from camera. It worked all most of devices but I got the following crash errors on DroidX device from android market.
I think imageCaptureUri can not be null in this case. So it is not the cause.
Do you have any ideas? Is it a firmware error?

Are you sure that image crop mode forcing
intent.putExtra("return-data", true);
works correctly for the device you use. Correct me if I am wrong, but it is not safe and not well documented approach. Here you can find example of working code without cropping.
UPDATE: Issue you are facing with has long history, also at SO:
https://stackoverflow.com/questions/3904685/unable-to-find-com-android-camera-cropimage-activity-in-android
Issue I experienced was using crop immediatelly after image was taken by the camera. Also, it is not compatible through different Android versions, so if you get it working for 1.5 maybe it will not work for 2.3. Definitely something is wrong, as may be concluded from the Android Developer Group posts:
