Camera Crop-Code does not work on Android 7.0

My Code works on all devices Android 4 till Android 6.x
But after I have updated my device on Android 7.0, the camera code does not work more. I get black screen !
I can make capture from camera but after that i get back screen if I want to crop the image
may be the crop funktion does not get the corect path of the bitmap
screen
any Idea? here is the code :
img = (ImageView) findViewById(R.id.imageView);
img_original = (ImageView) findViewById(R.id.imageView_original);
}
public void Capture(View view) {
Capture_Cam();
}
private void Capture_Cam() {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 1);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1 && resultCode == RESULT_OK && data != null) {
picUri = data.getData();
try {
// bitmap2 = MediaStore.Images.Media.getBitmap(this.getContentResolver(), picUri); // bitmap2 = original before cur
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse("file://"+picUri));
img_original.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
performCrop();
} else if (requestCode == 2) {
bitmap2=(Bitmap) data.getExtras().get("data");
img.setImageBitmap(bitmap2);
}else{
super.onActivityResult(requestCode, resultCode, data);
}
}
private void performCrop(){
try {
Intent cropIntent = new Intent("com.android.camera.action.CROP");
//indicate image type and Uri
cropIntent.setDataAndType(picUri, "image/*");
cropIntent.putExtra("crop", "true");
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
cropIntent.putExtra("outputX", 100);
cropIntent.putExtra("outputY", 100);
cropIntent.putExtra("scale", true);
cropIntent.putExtra("return-data", true);
startActivityForResult(cropIntent, 2);
Toast toast = Toast.makeText(this, "Done", Toast.LENGTH_SHORT);
}
catch(ActivityNotFoundException anfe){
//display an error message
String errorMessage = "Whoops - your device doesn't support the crop action!";
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
}

android- performing crop image is not working properly

I'm working with android crop image , this is my code for cropping image :
private void performCrop() {
try {
Intent cropIntent = new Intent("com.android.camera.action.CROP");
//indicate image type and Uri
cropIntent.setDataAndType(picUri, "image/*");
//set crop properties
cropIntent.putExtra("crop", "true");
//indicate aspect of desired crop
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
//indicate output X and Y
cropIntent.putExtra("outputX", 500);
cropIntent.putExtra("outputY", 500);
//retrieve data on return
cropIntent.putExtra("return-data", true);
//start the activity - we handle returning in onActivityResult
startActivityForResult(cropIntent, PIC_CROP);
} catch (ActivityNotFoundException anfe) {
//display an error message
String errorMessage = "err";
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
}
I have tested this code on android 4.2 , 4.3 and the was no problem , but on android 5,6 , it's returning null pointer exception and I don't know why .
what is wrong with this code ? how can I make it compatible with all version of android ?

You can use according to Build SDK
if (android.os.Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP) {
performCrop(fileUri);
} else {
performCropImage(fileUri);
}
// code for device below 5
private boolean performCropImage(Uri mFinalImageUri) {
Uri mCropImagedUri;
try {
if (mFinalImageUri != null) {
//call the standard crop action intent (the user device may not support it)
Intent cropIntent = new Intent("com.android.camera.action.CROP");
//indicate image type and Uri
cropIntent.setDataAndType(mFinalImageUri, "image/*");
//set crop properties
cropIntent.putExtra("crop", "true");
//indicate aspect of desired crop
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
cropIntent.putExtra("scale", true);
// cropIntent.p
//indicate output X and Y
cropIntent.putExtra("outputX", 200);
cropIntent.putExtra("outputY", 200);
//retrieve data on return
cropIntent.putExtra("return-data", false);
File f = createNewFile("CROP_");
try {
f.createNewFile();
} catch (IOException ex) {
Log.e("io", ex.getMessage());
}
mCropImagedUri = Uri.fromFile(f);
cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, mCropImagedUri);
//start the activity - we handle returning in onActivityResult
startActivityForResult(cropIntent, PIC_CROP);
return true;
}
} catch (ActivityNotFoundException anfe) {
//display an error message
String errorMessage = getString(R.string.crop_not_supported);
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
return false;
}
return false;
}
// code for 5 or 6
private void performCrop(Uri picUri) {
try {
Intent cropIntent = new Intent("com.android.camera.action.CROP");
// indicate image type and Uri
cropIntent.setDataAndType(picUri, "image/*");
// set crop properties
cropIntent.putExtra("crop", "true");
// indicate aspect of desired crop
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
// indicate output X and Y
cropIntent.putExtra("outputX", 200);
cropIntent.putExtra("outputY", 200);
// retrieve data on return
cropIntent.putExtra("return-data", true);
// start the activity - we handle returning in onActivityResult
startActivityForResult(cropIntent, PIC_CROP);
}
// respond to users whose devices do not support the crop action
catch (ActivityNotFoundException anfe) {
// display an error message
String errorMessage = getString(R.string.crop_not_supported);
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
}
On ActivityResult put this code
Uri imageUri = data.getData();
try {
Bitmap selectedBitmap;
if (android.os.Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP) {
Bundle extras = data.getExtras();
selectedBitmap = extras.getParcelable("data");
} else {
selectedBitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
}
// I hope you this code help you

Have a user crop an image

I Currently have it where a user pics an image from gallery. It is then converted to a bitmap and displayed in a imageview and sent to my server. The way I currently have it being cropped is bellow. However, I want the user to have a 300x300 box they can move around and when they press upload it will upload what is within that 300x300 view
if (bitmap.getWidth() >= bitmap.getHeight()){
bitmap = Bitmap.createBitmap(
bitmap,
0,
0,
bitmap.getHeight(),
bitmap.getHeight()
);
}else{
bitmap = Bitmap.createBitmap(
bitmap,
0,
0,
bitmap.getWidth(),
bitmap.getWidth()
);
}
This is my first application so I am still earning the ropes. Thank you for your time and patience ahead of time.

This is a sample function to crop a image of desired size.Please do check it.you can call this 'performCrop()' function from onActivityResult().
public void performCrop() {
try {
// call the standard crop action intent (the user device may not
// support it)
Intent cropIntent = new Intent("com.android.camera.action.CROP");
// indicate image type and Uri
cropIntent.setDataAndType(selectedImageUri, "image/*");
// set crop properties
cropIntent.putExtra("crop", "true");
// indicate aspect of desired crop
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
// indicate output X and Y
cropIntent.putExtra("outputX", 300); //your desired size here
cropIntent.putExtra("outputY", 300); //your desired size here
// retrieve data on return
cropIntent.putExtra("return-data", true);
File f = createNewFile("CROP_");
try {
f.createNewFile();
} catch (IOException ex) {
} catch (NullPointerException ex) {
}
CropImagedUri = Uri.fromFile(f);
cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, CropImagedUri);
// start the activity - we handle returning in onActivityResult
startActivityForResult(cropIntent, 2);
} catch (ActivityNotFoundException anfe) {
// display an error message
String errorMessage = "Whoops - your device doesn't support the crop action!";
Toast toast = Toast
.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
PerformCrop();
// Img.setImageURI(selectedImageUri);
} else if (requestCode == 2) {
CropImagePath = getRealPathFromURI(CropImagedUri);
}
}

Android crop photo from camera

i want crop photo that i take from camera, so far i try do it like this but with no success
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));
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("outputX", 200);
intent.putExtra("outputY", 200);
getActivity().startActivityForResult(intent, REQUEST_CAMERA);
is it possible to do it without any 3th part libraries.?
i checked https://github.com/biokys/cropimage
but it doesnt gave me any results
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
String path = data.getStringExtra(CropImage.IMAGE_PATH);
// if nothing received
if (path == null) {
return;
}
// cropped bitmap
Bitmap bitmap = BitmapFactory.decodeFile(path);
((ImageView) findViewById(R.id.userpicture)).setImageBitmap(bitmap);
}

is it possible to do it without any 3th part libraries.?
Not reliably. Android does not have a CROP Intent.
i checked https://github.com/biokys/cropimage but it doesnt gave me any results
Perhaps you did not integrate it properly. In addition to the libraries mentioned in my blog post (linked to above), the Android Arsenal has a few options.

try this
private void performCrop(Uri picUri) {
try {
Intent cropIntent = new Intent("com.android.camera.action.CROP");
// indicate image type and Uri
cropIntent.setDataAndType(picUri, "image/*");
// set crop properties
cropIntent.putExtra("crop", "true");
// indicate aspect of desired crop
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
// indicate output X and Y
cropIntent.putExtra("outputX", 128);
cropIntent.putExtra("outputY", 128);
// retrieve data on return
cropIntent.putExtra("return-data", true);
// start the activity - we handle returning in onActivityResult
startActivityForResult(cropIntent, PIC_CROP);
}
// respond to users whose devices do not support the crop action
catch (ActivityNotFoundException anfe) {
// display an error message
String errorMessage = "Whoops - your device doesn't support the crop action!";
Toast toast = Toast.makeText(getActivity(), errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
}
declare:
final int PIC_CROP = 1;
at top.
In onActivity result method, writ following code:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PIC_CROP) {
if (data != null) {
// get the returned data
Bundle extras = data.getExtras();
// get the cropped bitmap
Bitmap selectedBitmap = extras.getParcelable("data");
imgView.setImageBitmap(selectedBitmap);
}
}
}

Image quality decreases after cropping image

*I am working on an application in which i have to take image,crop it and then proceed to further implementation.When i capture image and save it to sdcard it's quality is good but when i try to save image after cropping,It's quality is worst.
Below is my code
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
if (arg0.getId() == R.id.captureimage) {
try {
//use standard intent to capture an image
final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA_CAPTURE);
}
catch(Exception e){ String errorMessage = "your device doesn't support capturing images!";
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();}
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_CAPTURE) {
Uri picUri = data.getData();
performCrop(picUri);
}
else if(requestCode == PIC_CROP){this.finish();
Intent i=new Intent(getApplicationContext(),display.class);
i.putExtra("jao", "jao");
startActivity(i);}
else {
Log.v("", "User cancelled");
}
}private void performCrop(Uri picUri) {
// TODO Auto-generated method stub
Intent cropIntent = new Intent("com.android.camera.action.CROP");
//indicate image type and Uri
cropIntent.setDataAndType(picUri, "image/*");
//set crop properties
cropIntent.putExtra("crop", "true");
//indicate aspect of desired crop
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
//indicate output X and Y
cropIntent.putExtra("outputX", 256);
cropIntent.putExtra("outputY", 256);
File file = new File(_path);
Uri outputFileUri = Uri.fromFile(file);
cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
//retrieve data on return
cropIntent.putExtra("return-data", true);
//start the activity - we handle returning in onActivityResult
startActivityForResult(cropIntent, PIC_CROP);
}
Please guide me how can i make my cropped image quality better because with bad quality image i cannot do my other tasks....
