You can use this scale down function
public static Bitmap scaleDown(Bitmap your_image, float YOUR_SIZE,boolean filter) { //filter false = Pixelated, true = Smooth
float ratio = Math.min( YOUR_SIZE/ your_image.getWidth(),
YOUR_SIZE/ your_image.getHeight());
int width = Math.round( ratio * your_image.getWidth());
int height = Math.round( ratio * your_image.getHeight());
Bitmap newBitmap = Bitmap.createScaledBitmap(your_image, width, height,
filter);
return newBitmap;
}

You already have the mechanism for compressing in your code:
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
See the documentation:
https://developer.android.com/reference/android/graphics/Bitmap.html#public-methods_1
Basically you need to change 100 to a lower number in order to compress the image.

URI Location to save a photo

How to create URI Location to save a photo captured by a camera?
I created a intent to start camera to captured photo. I want to pass URI location through the EXTRA_OUTPUT extra. How to generate such URI.

I created PictureUtils class for capture image from camera and Gallery. Here is below code

Now you can call camera intent using below way on click of any button.
Global Declaration : Uri fileUri;
PictureUtils images = new PictureUtils(ArtistAddEditMembers.this);
fileUri = images.openCameraIntent(REQUEST_OPEN_CAMERA);
You can handel the result in onActivityResult method using below way.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == REQUEST_OPEN_CAMERA) {
try {
PictureUtils images = new PictureUtils(ArtistAddEditMembers.this);
PictureUtils.ImagesData imagesData = images.resultFromCamera(data);
imageFile = imagesData.getImageFile();
finalBitmap = imagesData.getBitmap();
displayImagePreview(finalBitmap);
} catch (Exception e) {
e.printStackTrace();
}
} else if (requestCode == REQUEST_OPEN_GALLERY) {
try {
PictureUtils images = new PictureUtils(ArtistAddEditMembers.this);
PictureUtils.ImagesData imagesData = images.imageFromGallery(data);
imageFile = imagesData.getImageFile();
finalBitmap = imagesData.getBitmap();
displayImagePreview(finalBitmap);
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
For Display image in imageview
public void displayImagePreview(Bitmap bitmap) {
Glide.with(mContext).load(bitmap).into(ivUserProfile);
}
or you can simply set image bitmap in imageview without using glide.
I handeled below case in above example.
If version is >= N, the I am using FileProvider.getUriForFile and Uri.fromFile for lower version.
Display right rotation of Image instead of Display image after rotate.
Add below code in AndroidManefest.xml file under application tag for file provider
<application
......>
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/filepaths" />
</provider>
</application>
Create filepaths.xml file under xml resource directory
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path name="external_files" path="."/>
</paths>
Make sure you popup and handel runtime permission for Camera and Write Internal Storage permission before call camera intent.

Use this code for generate and call that file into camera intent
File imagefile = null;
try {
imagefile = createImageFile();
} catch (IOException ex) {
// Error while creating the File
Log.i(TAG, "IOException");
}
if (imagefile != null) {
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
startActivityForResult(cameraIntent, REQUEST_IMAGE_CAPTURE);
}
here is code of generate Imagefile
private File createImageFile() throws IOException {
String imageFileName = "JPEG_" + System.currentTimeMillis() + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, // prefix
".jpg", // suffix
storageDir // directory
);
return image;
}

private void SaveImage(Bitmap finalBitmap) {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-"+ n +".jpg";
File file = new File (myDir, fname);
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}

Taking photo fails with "requires android:camera"

Im taking a photo with the following code
Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File photoPath = new File(getExternalFilesDir(null), "postcard.jpg");
takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photoPath));
log.debug("start camera for {}", photoPath.getAbsolutePath());
startActivityForResult(takePhotoIntent, REQUEST_TAKE_PHOTO);
...
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_TAKE_PHOTO) {
if (resultCode == RESULT_OK) {
log.debug("photo successfully created");
} else {
log.error("problem to take photo resultCode={}", resultCode);
}
} else {
log.debug("not my request: {}", requestCode);
}
}
This works fine on Android 5, but fails on Android 6 with resultCode=0 (RESULT_CANCELED) and the logcat error message:

21309:censored.package.name.here/u0a136} (pid=21309, uid=10136)
requires android:camera
I have the following in the Android Manifest:
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
I also check if the application really has the camera permission, this check passes.
checkSelfPermission(Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED
Also worth noting, I include an aar in the project that also uses the camera. This included library has this in the manifest:
<uses-feature android:name="android.hardware.camera" android:required="false"/>
<uses-feature android:name="android.hardware.camera.front" android:required="false"/>
<uses-feature android:name="android.hardware.camera.autofocus" android:required="false"/>
<uses-feature android:name="android.hardware.camera.flash" android:required="false"/>
<uses-feature android:name="android.hardware.screen.landscape" android:required="false" />
<uses-feature android:name="android.hardware.wifi" android:required="false"/>
Does anybody have an idea what the error message means or how to fix this? Google wasn't helpful in this case.
Up to now, I wasn't successful to reproduce the problem with a small example. It seems to be some interaction with another app part.

After more than a day experimenting and debugging it works now. The code is still exactly the same.
I guess, retracting the camera permission via the settings and then re-enabling it did the trick but I am not completely sure.
Posting this as an answer if somebody runs into the same problem.

Camera and picture selection crashes sometimes

I inserted on my application a section to take and select pictures, but unfortunately, sometimes, when I take a photo or I select a picture to save on my server, the application crashes. Is really weird because my application only crashes sometimes.
I'm receiving this error:
ViewRootImpl #2 Surface is not valid.
How can I check if the photo is null and prevent my application from crashing?
My code:
private void selectImage() {
final CharSequence[] options = {"Take photo","My gallery","Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(PhotosActivity.this);
builder.setTitle("Adicionar foto!");
builder.setItems(options, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("My gallery"))
{
Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 2);
}
else if (options[item].equals("Take photo")){
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));
startActivityForResult(intent, 1);
}

}
}
