BitmapFactory: Unable to decode stream: java.io.FileNotFoundException even when file IS actually there

I'm creating a simple app to take a picture. this is my code

Button b1;
ImageView iv;
String TAG = "MAIN ACTIVITY";

File photo;
private Uri mImageUri;


private File createTemporaryFile(String part, String ext) throws Exception {


    File externalStorageDirectory = Environment.getExternalStorageDirectory();
    File tempDir = new File(externalStorageDirectory + "/cameratest/");
    if (!tempDir.exists()) {
        tempDir.mkdir();

    }
    return File.createTempFile(part, ext, tempDir);
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    b1 = (Button) findViewById(R.id.button);
    iv = (ImageView) findViewById(R.id.imageView);

    b1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

            try {
                // place where to store camera taken picture
                photo = createTemporaryFile("picture", ".jpg");
                photo.delete();
            } catch (Exception e) {
                Log.v(TAG, "Can't create file to take picture!");
                Toast.makeText(getApplicationContext(), "Please check SD card! Image shot is impossible!",
                        Toast.LENGTH_SHORT).show();

            }

            mImageUri = Uri.fromFile(photo);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri);

            startActivityForResult(intent, 0);
        }
    });
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);


    if (requestCode == 0 && resultCode == RESULT_OK) {



        Log.d(TAG, mImageUri.toString());
        Bitmap bitmap = BitmapFactory.decodeFile(mImageUri.toString());
        iv.setImageBitmap(bitmap);

    }


}

as you can see i've added eLog.d(TAG, mImageUri.toString()); at the end and in the logcat (as well as the FileNotFoundException) i see this direcory:

03-27 00:43:30.498 30526-30526/myapplication.example.falcoleo.cameratest1 D/MAIN ACTIVITY: file:///storage/emulated/0/cameratest/picture459838058.jpg
03-27 00:43:30.499 30526-30526/myapplication.example.falcoleo.cameratest1 E/BitmapFactory: Unable to decode stream: java.io.FileNotFoundException: file:/storage/emulated/0/cameratest/picture459838058.jpg: open failed: ENOENT (No such file or directory)

guess if this directory exists? spoler alert, it does. And it's not like the image is created after the BitmapFactory.decodeFile. I really do not understand what i'm doing wrong. Everything works fine except when it actually has to display the photo, then it just does not display it. just blank. Like WTF m8 i'm just trying to do my job no need to go crazy, you know.

Ok for me it was the file path was wrong so I needed to get the real filepath.

First

File file = new File(getPath(uri));

public String getPath (Uri uri)
{
    String[] projection = {MediaStore.Images.Media.DATA};
    Cursor cursor = getContentResolver().query(uri,
                                               projection,
                                               null,
                                               null,
                                               null);
    if (cursor == null)
        return null;
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    String s = cursor.getString(column_index);
    cursor.close();
    return s;
}

Then Back To Uri

Uri newUri = Uri.fromFile(file);

This conversion to file and back to uri did the trick for me. I was receiving simple data from action.SEND.

Use BitmapFactory.decodeStream instead of BitmapFactory.decodeFile.

try ( InputStream is = new URL( file_url ).openStream() ) {
  Bitmap bitmap = BitmapFactory.decodeStream( is );
}

Replace mImageUri.toString() with mImageUri.getPath().

decodeFile expects a path, not an uri string.

file:///storage/emulated/0/cameratest/picture459838058.jpg

Remove file:// because the decodeFile() expects a file system path.

/storage/emulated/0/cameratest/picture459838058.jpg
