Fingertip drawing applications on Android? - java

I'm a new user to this interesting forum!
I want start developing an application for android and before starting i want learn about some android features...
The first android feature is how to correlate finger motion on the screen with java...
Are there any source code examples that show how to draw with your finger on an android screen?
Can you suggest a good place for me to download an example?
thanks

The ApiDemos that come with the SDK have an example called TouchPaint that does exactly this... it's a simple little finger drawing app. The source is actually very easy to read and it shows all of the basics.

Check out this tutorial on drawing with a canvas in Android. There are some source code examples there for you as well.
Also, the Android developer's guide and tutorials on the Google site are great. That's what I started with.

Can I start Android App not in FullScreen mode?

I saw that youtube app can minimize to small window that displays over all other windows.
I want to do the same with my app.
What strings in manifest (or any other string) do it?
Thanks,
I am about this:
Take a look at google documentation about this topic, it is called picture-in-picture
You need to add the first two lines to your activity which will handle Picture in Picture (PIP) mode.
The third line needs to be added so that your activity will not relaunch once layout changes occur, such as device screen rotation.
android:resizeableActivity="true"
android:supportsPictureInPicture="true"
android:configChanges="screenSize|smallestScreenSize|screenLayout|orientation"
You can find more information about this in the android documentation.
Here is a tutorial on how to implement it.
You can refer to the following tutorials which are nice to understand

Android Camera preview with funhouse mirror effect

I created a android small app that uses the front facing camera to shoot a selfie. But what i want to accomplish is a funhouse mirror effect.
I searched the internet trying to find a solution or a way to do this but i am guessing i am searching for the wrong terms here:
Sample Image
Can someone push me in the right direction or how this is made? I searched for morphing, distortion etc.
What i have right now:
A basic camera app wich is saving a taken photo using the Camera2 API in Android SDK 23
Just only Camera2 API are not enough to develop an app which is like mentioned you. You should use computer vision libraries such as OpenCV or OpenGL.
First of all, please check it out for creating theoretical background.
Here is an example application which is using OpenCV and it is about funny effects.
This can be another reference application which is about fun house effects and it was developed by using GLSL.
Also this post can be helpful for you.
Moreover, you can check it and it out. And, you can use "image warping" term to search to find solutions for your problem on internet.

3d effects in android and Iphone

We have a lot of days of research but can't find a solution for the following project. We need to convert a flux project to IOS and android native app. But as flux supports flash scripting it has easily implementing some 3d effects like shadow, emboss gradient etc. Please check the link here for seeing the swf file we have. We need to convert all this features into a native IOS and android app. We have research some area and found that most of the item we can implement except one icon here. The fourth icon have some 3d effects, shadow effects, border, emboss, contour and gradient etc. Can anybody check on this and guide us whether this can be implemented in IOS and android. I am pasting the entire url here again http://projects.zoondia.org/signfabcreator/signCreator.swf. Please check and let me know if this is possible. Let me if this is possible or not. If yes it will be helpful for me if anybody can give me a clue about implementing those in both android and ios
Very interesting! But I'm afraid you have to reimplement all this functionality by yourself. Don't be upset. There are good news for you - OpenGL ES and GLSL are extremely portable. So you can reuse 100% of your shaders. What is even better now you can share the other code too and stay native. Not long ago Intel announced the Multi-OS Engine. It enables you to develop native mobile applications for iOS and Android with Java. There are a bunch of tutorials inside installation package. One of them is especially dedicated to cross-platform OpenGL capabilities. Please check out my OpenGLBox sample.

How to build an Android widget that plays video

I'm wanting to build an Android widget for my phone that streams a video from a link on button click. I've searched tutorials on Google but I'm still having difficulty understanding how I'd achieve this.
Does anybody have an example of something similar to this or know of any good tutorials to get me started?
Cheers
You can use android native VideoView. It can even play online streaming videos.

Directing to a Second Menu on Android

I'm very new to Android programming and working on Android Studio. I want to go to a second menu by clicking on a button and I will need these kind of stuff during my development. Is there any good tutorial that you know for Java for Android? Android's own tutorial is not very sufficient and there are lots of tutorials about android but all of them are very complex. I'm looking for something like android for dummies or something :)
Thank you very much.
Android has the concept of Fragments and Activites for different views.
The Android training guide by google is really superb for the basics and have the sample code too, you should start from there
For the different views, here is a guide for that using fragments
