Camera Intent destroys Activity

I am posting this question after several days of fighting with this problem. I have Floating Action Button and onClick listener calls takePhoto() method, where I obviously want to take a photo and save its Bitmap, which I will use later to save it in Database. But that's not the main problem. I start onActivityResult (...) to get data of taken photo. When I take photo and click save, the activity is simply destroyed (I used Log.v (...) to check if it actually is destroyed) I tried almost everything including overriding onSaveInstanceState (...) and so on. Here is my Android manifest file and part of that code.

Manifest:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.alexparunov.collegemascots" >

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".account.SignIn"
              android:label="@string/title_activity_login">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".account.SignUp"
              android:label="@string/title_activity_register"/>
    <activity
        android:name=".profile.MainProfile"
        android:configChanges="orientation|keyboardHidden|screenSize"
        android:screenOrientation="portrait"
        android:noHistory="true"/>
</application>

Java: private static final int REQUEST_IMAGE_CAPTURE = 1;

private void takePhoto(){
    if(ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED){
        ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.CAMERA},1);
    }
    Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if(cameraIntent.resolveActivity(getPackageManager()) != null) {
        startActivityForResult(cameraIntent, REQUEST_IMAGE_CAPTURE);
    }
    Image finalImage = new Image();
    if(user != null && imageBitmap != null) {
        finalImage.setImageOwner(user.getUsername());
        finalImage.setImageName(generateName());
        finalImage.setImage(ImageUtils.getBytesFromBitmap(imageBitmap));

        try {
            ImageDatabase imageDatabase = new ImageDatabase(this);
            imageDatabase.open();
            finalImage.setImageId(imageDatabase.createImage(finalImage));
            Log.v("TakeImage",""+finalImage.getImageId());
            imageDatabase.close();
            images.add(finalImage);
            user.setImages(images);
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if(requestCode == REQUEST_IMAGE_CAPTURE && resultCode == Activity.RESULT_OK) {
        Bundle extras = data.getExtras();
        imageBitmap = (Bitmap) extras.get("data");
    }
}

private String generateName(){
    String name = user.getName()+"_";
    if(images != null) {
        name += images.size() + ".png";
    }
    return name;
}
