Expected behavior

Many people who love to draw have a habit of rotating their canvas inorder to draw easily. This should also be possible on the 'Draw app' without any glitch, hence drawing on landscape would fit into portrait during rotation and vise versa.

Actual behavior

Rotating the device when it is set to 'Auto rotate' changes the rotation of the screen, thereby displacing the image on the workspace. Sometimes a part is hidden, and someime the whole of it.

How to reproduce

• Set the device screen orientation to "Auto rotate"
• Launch the "Simple Draw App.
• make a drawing on its workspace
  *Tilt the phone to 180° to use a different orientation
• And the bug should be visible.

Testing Environment

• Browser: Google Chrome
• Operating system: Android version 7 (nougat)
• App Version: Draw v3.1.4

Recording Of The Bug

Is it possible to insert a 'ruled' background enabling a easier note taking as used in write (see https://play.google.com/store/apps/details?id=com.styluslabs.write&hl=en)

Please, add an ability to rotate the image;

Or, in alternative, change the position of the color box (for example on the bar)

The simplemobile calendar widget is great; swiping to get a screen that has a full calendar is so useful.

I'd love to get a similar widget for draw, where it has a full screen canvas. Just swipe and draw, basically. It would be even more excellent for taking notes, or quickly creating a diagram for help explaining something complex in conversations.

Expected behavior

I expected after drawing and saving even after erasing the drawing pad to draw another image, I'd be able to open the saved drawing and either edit or continue drawing.

Actual behavior

The Saved drawing is opened into the drawing pad with stains of traces from the eraser tool, with the background colour as trace colour. Totally hiding what was drawn and saved.

How to reproduce

• Download the app.

• change the default white background to any colour of your choice.

• draw and save the image in png.

• delete the drawn object then try opening the saved file.

• Device: Tecno K7

• Operating system: Android 7.0

• App Version: 3.1.6

Could you add a rubber mode to quickly erase?
This should be a simple button that sets pen color as background and increases a bit the thickness.

As in title.

Sometimes you want to briefly minimize S or L while preserving the current hue.

Thank you.

it would be nice if the app supported multi-touch for drawing

Following flow i wish for the app:

1. It should be possible to draw something in the canvas
2. User can scroll the canvas to see more white space
3. Users's previous drwaing/work should be scrolled with the sreen flow
4. export all the work as .png or .pdf

Expected behavior

I opened image in app to draw something on image. After opening image file, if i rotate my device from portrait to landscape or landscape to portrait, the app needs to keep the opened image not to remove them from my canvas.

Actual behavior

I opened image in app to draw something on image. Now the image is on my canvas, if i rotate my device from portrait to landscape or landscape to portrait, the image just disappears from my canvas.

How to reproduce

To reproduce the bug, follow the following steps :-

• Download app from playstore or f-droid.
• Open app and click on three dots on top right of app nav bar. A menu will appear, now select open file from menu and choose any image from your device gallery.
• Now you see your image is on canvas. Now rotate your screen from portrait to landscape or landscape to portrait and the image got disappears and don't came back.

* Device:  Samsung J7 Prime
* Operating system: Android 7.0 Nougatt
* App Version: v3.1.5

I do not know if this fits with the aim of being simple. Here is a description of what I have in mind.

Fingers crossed!

I think the UI could be simplified, with every tool being in the menu bar.
Also, the "C" button could be in the "more" menu, as it's in my opinion better if it's not to easy to access, to avoid deleting current drawing by accident.

Also it seems that the title "Draw" is not really necessary and could let space to have more tools in toolbar, or to make them distant and more easily clickable.
It could look like the following picture.

Maybe an even better option would be to have the drawing full screen and all tools in a sidemenu.

What do you think?

Changing the thickness would dramatically enhance the types of use.

I'd like to integrate Kontalk with your app, in such a way that I can send an intent to invoke your app, the user draws something and, when finished, the output is returned to Kontalk so it can be sent as a message. What do you think? The intent can be used by other apps as well of course.

You could use (along with your custom intent name) the IMAGE_CAPTURE intent so the interface would be standard.

Dear developers,

We have recently developed a state-of-the-art static analysis tool for uncovering API compatibility issues in Android apps. Applying this tool to open source apps on F-droid, we have exposed a few instances of compatibility issues and submitting them to development teams for a fix.

For your app, we have found that this project has accessed the following APIs which are available only on an API level higher than the declared minSdkVersion and which are accessed without proper protection. In other words, if those APIs get called at runtime, it will trigger a NoSuchMethodError and thus result in a crash of the running application.

<android.app.Activity: void onRequestPermissionsResult(int,java.lang.String[],int[])>:[23,25]

Note that, because of the nature of the static analysis, we cannot confirm whether the flagged APIs would actually be called at runtime (e.g., unreachable code). However, we still believe that those APIs, which may cause compatibility issues, should not be accessed or at least be accessed with proper protections.

In addition to the aforementioned APIs (i.e., backward-compatibility), which could cause app crashes if accessed, we have also identified that this project has also accessed some APIs that have been removed from the latest public SDK, making the app possibly suffer from forward-compatibility issues.

NONE

We would be very much appreciated if you can acknowledge to us that those reported APIs are indeed problematic for the project’s long-term stability. please let us know if you need any more information relating to this issue report.

It's possible to embed images on .svg files, as the following "example" shows:

<image
    y="0"
    x="0"
    xlink:href="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgA…"
    preserveAspectRatio="none"
    height="568"
    width="512" />

This is what inkscape saves.

Could you add a button to redo something you've undone?
(To clarify this should be like CTRL-Y)

Hey, below are the apk test result from Hybrid Analysis.
Hybrid Analysis Link : HERE

Saving the picture as .svg would allow to edit it easily afterwards

When you try to save a drawing for the first time, if you don't change the folder or create the default one manually, it fails with "An unknown error occurred."

Consider providing a more useful error or, better yet, create this folder if it doesn't exist.

Android 8.1 arm64, OnePlus 5, LineageOS 15.1 official 20180305 Nightly

I can see the picture taken with simple camera in file manger.

When i click in File manager on the .png than open with "Draw" i get the notification : Invalid file format"

S8 with OS 8.0.0

First of all, thanks for this great app!
I was searching for a JetDraw FOSS replacement for a long time and now I finally found this nice app. Although its still missing some features, its already one of my favorite apps – not bloated, following the KISS principle...
However, I'm quite confused by the app name: F-Droid lists it as "Draw", here it's name is "Simple Draw". Is there a reason for this non-consistent app name? Otherwise I would suggest to stick to one name, so it can be found on all platforms (e.g. F-Droid and GitHub) easily.
Merry Christmas! 🎅

Hi @tibbi

I found this app called Drawing Easy Draw On Screen on the Google Play Store. This guy just took your source code, added some ads in it and put it on the Store, without warning this is free software...

As you are the owner of the source code, feel free to open a request to google here to remove this copy from the Store, if it's your wish ;)

Don't forget to tell Google that:

• The app is licensed under Apache v2 license and this guy is violating it;
• He is falsely claiming he made the app;
• Provide some screenshots of your own app.

currently the clear action cannot be undone, so if you hit the button accidentally, all is lost...

I tried changing the directory and no folders where showing under /Internal (perhaps this bug should go to the common repository which holds these utilities, like the select folder dialog)

System version: Marshmallow. It didn't ask me for internal storage permissions so that's probably the cause.

Edit: Without changing the directory (default to Internal/Simple Draw), it shows a toast saying "An unknown error occured" for both .png and .svg.

Expected behavior

while drawing , click on setting, activate 'show brush size tool' from the setting, then return to my drawing and continue were i stopped

Actual behavior

while drawing , clicked on setting, activate 'show brush size tool', then return to my drawing and all my work cleared.

How to reproduce

download simple draw version 3.1.5 from F-Droid on this address https://f-droid.org/packages/com.simplemobiletools.draw/ . install and run, draw anything on the draw board, click on the 3 dotted line at the top right hand side of the app, then select setting from the drop down menu, activate 'show brush size tool' by clicking on it, then return to your work/drawing by clicking the return key at the top left hand side. the bug will be reproduced .

• Browser: Simple Draw version 3.1.5
• Operating system: Android 5.1.1 Lollipop. Infinix hot 3 LTE

Recording Of The Bug

There is no browse icon, edit icon, or any other visual indicator that the save path can be changed by tapping or through any other method. When combined with another current issue (default save location doesn't exist, causing "unknown error"), the user finds themselves unable to save their drawing.

Simple-Draw is listed on f-droid (only) under 'System' where I found it by accident.
It should be listed under 'Graphics' and 'Writing'.

BR

Expected behavior

Users should be able to save the drawings made with the draw app.

Actual behavior

When trying to engage a save operation, the process ends up with an error report "Unexpected error occured".

How to reproduce

• Launch Simple Draw application .
• Make a drawing
• Attempt saving with the diskette icon just at the top of the workspace.

Testing Environment

• Browser: Google Chrome
• Operating system: Android version 7 (Nougat)
• App Version: Draw v3.1.4

Hello. Is it OK that this app croping images horizontally from bottom and above?

Expected behavior

When a file is inserted or imported to the app to work on, it should be on the screen whether I'm portrait of landscape view.

Actual behavior

The imported /inserted file disappears totally when screen orientation is changed either from portrait to landscape of vice versa.

How to reproduce

1. Download the latest version of simple draw.
2. Launch the app
3. Click on menu (3 dots on the top right corner)
4. Click on open file and select a file (picture or document) to import
5. Set phone to auto rotation
6. Tilt of rotate phone from portrait view to landscape of vice versa.

Could work like the zoom of the F-droid app Markers, but needs to support bigger images and have a (temporary) ruler to better judge the zoom.

Hello, the simplicity of this app is amazing. Would it be possible to allow for a transparent background? It would be handy for producing hand written signatures to save to file.

As simple as replacing:

new AmbilWarnaDialog(this, color, new AmbilWarnaDialog.OnAmbilWarnaListener() {

with

new AmbilWarnaDialog(this, color, true, new AmbilWarnaDialog.OnAmbilWarnaListener() {
//                                ^ note the true

Is there any reason why this wasn't done yet? It gives the "brush" a marker-like feel.
