I need to access the specific folder depending on the name of the created project. In Main_Activity the name of this project is filled and new folder is created. Thus, Camera_Activity saves the photos taken in that folder. Next I access Gallery_Activity, but it never goes to the folder of the created project. How can I access to that folder?
An example: Name of the created folder: Proj_1, but user select the photos from another one that opens by default, the uri that comes out is:

Can someone advise me on how I can solve this problem?
It is clear that I could leave things as they are and tell the user to check the folder where he selects the photos. But I would like it to be something more fluid and intuitive.
Thanks in advance.
private ArrayList<File> m_list = new ArrayList<File>();
String folderpath = Environment.getExternalStorageDirectory()
+ File.separator + "folder_name/";
File dir = new File(folderpath);
m_list.clear();
if (dir.isDirectory()) {
File[] files = dir.listFiles();
for (File file : files) {
if (!file.getPath().contains("Not_Found"))
m_list.add(file);
}
}

I would like to add that after the emotionInfo.
I guess detectWithStream is you want.

From Java SDK, the List<DetectedFace> object will return if successful.
So I am populating my Bitmap ArrayList (photos) by adding images through gallery and camera photos and then saves the array of names into database and images into the storage. In the ImageAdapter class if I remove an image from the array list then without saving the list it successfully removes the image from the storage but if I click the save button then it did not remove the image from my internal phone storage as my Bitmap ArrayList (photos) does not update. How can I update my Arraylist of Bitmap in the main class (fragment) before saving?

my ImageAdapter Delete bitmap class
public void showDeletePictureDialog(){
AlertDialog.Builder builder;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
builder = new AlertDialog.Builder(Imagecontext);
} else {
builder = new AlertDialog.Builder(Imagecontext);
}
builder.setTitle("Delete photo")
.setMessage("Are you sure you want to delete this photo?")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
ImageFileArrayAfterDelete = EditorFragment.loadImageStrings;
String folder_main = "MyImages";
File f = new File(Environment.getExternalStorageDirectory().toString(), folder_main);
z = new File(f.toString(), Uri.parse(String.valueOf(ImageFileArrayAfterDelete.get(currentPosition))) + ".jpg");
ImageName = z.getName();
Log.d("TAG_", "Position is: " + currentPosition + " File name is: " + ImageName);
bpAdapter.remove(currentPosition);
ImageFileArrayAfterDelete.remove(currentPosition);
toSingleString();
notifyItemRemoved(currentPosition);
notifyItemRangeChanged(currentPosition, bpAdapter.size());
z.delete();
}
})
You can achieve this just by doing this after deleting the item from your list
myList.removeAt(position)
myAdapter.notifyDataSetChanged()
So I'm working on a project where I take in an image from either gallery or camera and get a series of statistics from the image (brightness, contrast, sharpness, etc). Currently I have this working from gallery. I can open gallery, pull an image, and if a face is detected it will be cropped in a 2nd imageview. The stats are gathered from the cropped image ( see showimage(bitmap) in the gallery button area ). I've been struggling for the last week trying to get the same thing to work from the camera.
I'm currently using the following open source projects for getting the image from gallery and for cropping the face from the image:
https://github.com/hanscappelle/SO-2169649
https://github.com/lafosca/AndroidFaceCropper
I've made some advancements, and then backtracked a lot because I think I was trying to do it wrong. Here is my current working code for JUST gallery:
public class MainActivity extends AppCompatActivity {
// this is the action code we use in our intent,
// this way we know we're looking at the response from our own action
private static final int SELECT_SINGLE_PICTURE = 101;
public static final String IMAGE_TYPE = "image/*";
/* Get the reference to the text label */
TextView label = null;
private ImageView selectedImagePreview;
private ImageView imageViewFace;
void showImage(Bitmap image)
{
/* Get the starting time */
long startTime = 0;
startTime = System.nanoTime();
/* Get the image statistics */
ImageStats imageStats = new ImageStats(image);
System.out.println("Execution time: " + (((double)(System.nanoTime() - startTime))/1000000000.0) + " seconds!");
/* Get the image statistics */
double[] stats = imageStats.getStats();
/* Decide whether or not the image is of good quality */
String results = imageStats.result;
/* Create the labels */
String[] labels = new String[]{"Standard Luminosity: ", "Contrast: ", "Face orientation: ", "Sharpness: "};
/* The string of statistics */
StringBuffer strStatsBuff = new StringBuffer();
/* Go through all the statistics */
for(int statIndex = 0; statIndex < stats.length; ++statIndex)
{
/* Add the statistics */
strStatsBuff.append(labels[statIndex]);
strStatsBuff.append(String.valueOf(stats[statIndex]));
strStatsBuff.append("\n");
}
/* Add the file name */
strStatsBuff.append("\n");
strStatsBuff.append(results);
/* Set the label and show the cropped image */
label.setText(strStatsBuff.toString());
FaceCropper mFaceCropper = new FaceCropper();
mFaceCropper.setEyeDistanceFactorMargin(0);
image = mFaceCropper.getCroppedImage(image);

My "closest to working" method pulled an image from the camera, but both the original imageview and the imageview that should have been cropped to face both just showed the original image.
I had the following included under oncreate -
findViewById(R.id.buttonCamera).setOnClickListener(new View.OnClickListener(){
public void onClick(View arg0 ){
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
});
and this included in onactivityresult -
else if (requestCode==CAMERA_REQUEST && resultCode == RESULT_OK){
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
selectedImagePreview.setImageBitmap(bitmap);
showImage(bitmap);
}
Welcome to any suggestions! If you need any more info or I haven't provided something obvious, let me know. I'm new to stackoverflow, java, and android. Thanks!
I have a solution now. If anyone needs to do the same or similar here's what mine looks like:

// this is the action code we use in our intent,
// this way we know we're looking at the response from our own action
private static final int SELECT_SINGLE_PICTURE = 101;
private static final int CAMERA_REQUEST = 102;

/* Get the reference to the text label */

ImageView selectedImagePreview;
ImageView imageViewFace;
void showImage(Bitmap image)
{
imageViewFace.setImageBitmap(null);
FaceCropper mFaceCropper = new FaceCropper();
mFaceCropper.setMaxFaces(1);
mFaceCropper.setEyeDistanceFactorMargin(0);
image = mFaceCropper.getCroppedImage(image);
String faceFound;
if (mFaceCropper.faceDetected==true){
faceFound = "Face Detected!";
}else faceFound ="No face detected!";
/* Get the starting time */
long startTime = 0;
startTime = System.nanoTime();
/* Get the image statistics */
ImageStats imageStats = new ImageStats(image);
System.out.println("Execution time: " + (((double)(System.nanoTime() - startTime))/1000000000.0) + " seconds!");
/* Get the image statistics */
double[] stats = imageStats.getStats();
/* Decide whether or not the image is of good quality */
String results = imageStats.result;
/* Create the labels */
String[] labels = new String[]{"Standard Luminosity: ", "Contrast: ", "Face orientation: ", "Sharpness: "};
/* The string of statistics */
StringBuffer strStatsBuff = new StringBuffer();
/* Go through all the statistics */
for(int statIndex = 0; statIndex < stats.length; ++statIndex)
{
/* Add the statistics */
strStatsBuff.append(labels[statIndex]);
strStatsBuff.append(String.valueOf(stats[statIndex]));
strStatsBuff.append("\n");
}
/* Add the file name */
strStatsBuff.append(faceFound);
/* Set the label and show the cropped image */
label.setText(strStatsBuff.toString());
if (mFaceCropper.faceDetected == true)
{
imageViewFace.setImageBitmap(image);
}
}

I just bought a puzzle game source code from codecanyon yesterday and its not what I expected. User have to choose a image from gallery to start the puzzle, but I want it changed in this way > activity "Choose Puzzle" then user has to choose an image listed in that activity(not from gallery, from drawables).
Im 90% sure this is the "choose from gallery" button function code

Do you add the dropbox-android-sdk.jar in your buildPath and in a correct way ?
The DropboxAPI JAR file should be in the libs/ folder, not lib/.
Try this and tell me if it works now ...
PS: I'm working with DropboxAPI for android, and their code works very well for me and their documentation is really good to do your own application.
