how change quality of croped image in android

I made an android app that can take a picture from the gallery or camera.
Everything is fine, but when I crop the image, its size goes to 160px*160px.
I'm confused as to why it has changed the size of my picture....
private void doCrop() {
final ArrayList<CropOption> cropOptions = new ArrayList<CropOption>();
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setType("image/*");
List<ResolveInfo> list = getActivity().getPackageManager().queryIntentActivities(intent, 0);
int size = list.size();
if (size == 0) {
Toast.makeText(getActivity(), "no app for crop", Toast.LENGTH_SHORT).show();
return;
} else {
intent.setData(mImageCaptureUri);
// intent.putExtra("crop", "false");
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("outputX", 800);
intent.putExtra("outputY", 800);
intent.putExtra("scale", false);
intent.putExtra("return-data", true);
if (size == 1) {
Intent i = new Intent(intent);
ResolveInfo res = list.get(0);
i.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
startActivityForResult(i, CROP_FROM_CAMERA);
// mUploadMessage.onReceiveValue( mImageCaptureUri);
} else {
for (ResolveInfo res : list) {
final CropOption co = new CropOption();
co.title = getActivity().getPackageManager().getApplicationLabel(res.activityInfo.applicationInfo);
co.icon = getActivity().getPackageManager().getApplicationIcon(res.activityInfo.applicationInfo);
co.appIntent = new Intent(intent);
co.appIntent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
cropOptions.add(co);
}
CropOptionAdapter adapter = new CropOptionAdapter(getActivity().getApplicationContext(), cropOptions);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("app for crop?");
builder.setAdapter(adapter, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
startActivityForResult(cropOptions.get(item).appIntent, CROP_FROM_CAMERA);
}
});
AlertDialog alert = builder.create();
alert.show();
}
}
}

Call to system Camera returns null in fragment,but in activity it's ok

Intent openCameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
openCameraIntent.putExtra("return-data", true);
Uri imageUri = Uri.fromFile(new File(path));
openCameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
activity.startActivityForResult(openCameraIntent, CROP);
The code is in a ImageView click handler. When the view is in an activity, it's ok.
But when the view is in a fragment, the onActivityResult data is null

Whenever you specified MediaStore.EXTRA_OUTPUT, the image taken will be written to that path, and no data will given to onActivityResult. You can read the image from what you specified.
Otherwise to get data from result callback write your intent without specifying the Output uri as
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CROP);
You can take a look at this answer also

Intent intent = new Intent(
MediaStore.ACTION_IMAGE_CAPTURE);
private Uri mImageCaptureUri = Uri.fromFile(new File(
Environment
.getExternalStorageDirectory(),
"tmp_avatar_"
+ String.valueOf(System
.currentTimeMillis())
+ ".jpg"));
intent.putExtra(
android.provider.MediaStore.EXTRA_OUTPUT,
mImageCaptureUri);
try {
intent.putExtra("return-data", true);
startActivityForResult(intent,
PICK_FROM_CAMERA);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
then on activityresult put
if(requestCode==PICK_FROM_CAMERA)
{
doCrop();
}
else if(requestCode==CROP_FROM_CAMERA)
{
Bundle extras = data.getExtras();
Log.e("extras received from crop", extras.toString() + "yes yes");
if (extras != null) {
Bitmap photo = extras.getParcelable("data");
}
File f = new File(mImageCaptureUri.getPath());
if (f.exists())
f.delete();
}
here's do crop method
private void doCrop() {
final ArrayList<CropOption> cropOptions = new ArrayList<CropOption>();
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setType("image/*");
List<ResolveInfo> list = getActivity().getPackageManager()
.queryIntentActivities(intent, 0);
int size = list.size();
if (size == 0) {
Toast.makeText(getActivity(), "Can not find image crop app",
Toast.LENGTH_SHORT).show();
return;
} else {
intent.setData(mImageCaptureUri);
intent.putExtra("outputX", 200);
intent.putExtra("outputY", 200);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("scale", true);
intent.putExtra("return-data", true);
if (size == 1) {
Intent i = new Intent(intent);
ResolveInfo res = list.get(0);
i.setComponent(new ComponentName(res.activityInfo.packageName,
res.activityInfo.name));
startActivityForResult(i, CROP_FROM_CAMERA);
} else {
for (ResolveInfo res : list) {
final CropOption co = new CropOption();
co.title = getActivity().getPackageManager()
.getApplicationLabel(
res.activityInfo.applicationInfo);
co.icon = getActivity().getPackageManager()
.getApplicationIcon(
res.activityInfo.applicationInfo);
co.appIntent = new Intent(intent);
co.appIntent
.setComponent(new ComponentName(
res.activityInfo.packageName,
res.activityInfo.name));
cropOptions.add(co);
}
CropOptionAdapter adapter = new CropOptionAdapter(
getActivity(), cropOptions);
AlertDialog.Builder builder = new AlertDialog.Builder(
getActivity());
builder.setTitle("Choose Crop App");
builder.setAdapter(adapter,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
startActivityForResult(
cropOptions.get(item).appIntent,
CROP_FROM_CAMERA);
}
});
builder.setOnCancelListener(new DialogInterface.OnCancelListener() {
#Override
public void onCancel(DialogInterface dialog) {
if (mImageCaptureUri != null) {
getActivity().getContentResolver().delete(
mImageCaptureUri, null, null);
mImageCaptureUri = null;
}
}
});
AlertDialog alert = builder.create();
alert.show();
}
}

how to extract URI from the crop file?

I am able to crop a picture from the camera or the gallery and put it on an ImageView and it is correctly displayed.
But when I try to upload the picture to a server, the original picture was uploaded instead of the cropped one.
How do I get the URI of the cropped picture? I think I am missing something in CROP_FROM_CAMERA:
Pls help. Thanks very much.
My crop and onstartactivity is as follows:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// super.onActivityResult(requestCode, resultCode, data);
if (resultCode != RESULT_OK) return;
switch (requestCode) {
case PICK_FROM_CAMERA:
doCrop();
break;
case PICK_FROM_FILE:
mImageCaptureUri = data.getData();
doCrop();
break;
case CROP_FROM_CAMERA:
Bundle extras = data.getExtras();
if (extras != null) {
Bitmap photo = extras.getParcelable("data");
mImageView.setImageBitmap(photo);
// mImageCaptureUri = mImageView.;
}
// File f = new File(mImageCaptureUri.getPath());
// mImageCaptureUri = data.getData();
// if (f.exists()) f.delete();
break;
}
}
private void doCrop() {
final ArrayList<CropOption> cropOptions = new ArrayList<CropOption>();
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setType("image/*");
List<ResolveInfo> list = getPackageManager().queryIntentActivities( intent, 0 );
int size = list.size();
if (size == 0) {
Toast.makeText(this, "Can not find image crop app", Toast.LENGTH_SHORT).show();
return;
} else {
intent.setData(mImageCaptureUri);
intent.putExtra("outputX", 200);
intent.putExtra("outputY", 200);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("scale", true);

if (size == 1) {
Intent i = new Intent(intent);

final CropOption co = new CropOption();
co.title = getPackageManager().getApplicationLabel(res.activityInfo.applicationInfo);
co.icon = getPackageManager().getApplicationIcon(res.activityInfo.applicationInfo);
co.appIntent= new Intent(intent);
co.appIntent.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
cropOptions.add(co);
}
CropOptionAdapter adapter = new CropOptionAdapter(getApplicationContext(), cropOptions);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Choose Crop App");

Best practice is to save the cropped bitmap and get that file name you saved.

I have actually searched a bit on this . Actually I wanted to crop an image , Right now am using this piece of code.
Actually I wanted to put one more button in between 'SAVE' and 'DISCARD' like ' PROCEED WITHOUT CROPPING' .How can I do this . Should I create acustom class for this. If then, please tell how can i make that.Thanks in advance.
final ArrayList<CropOption> cropOptions = new ArrayList<CropOption>();

You can simply modify this library android-cropimage by adding and removing the buttons you need.
