Accessibility service dispatchGesture swiping the screen not tapping

I have been trying to make the accessibility service dispatchGesture with a click and not a swipe.
This code is just swiping down on the screen, and not actually clicking on the x,y cords.
What I have tried.
Path clickPath = new Path();
clickPath.moveTo(Float.intBitsToFloat(x), Float.intBitsToFloat(y));
GestureDescription.Builder gestureBuilder = new GestureDescription.Builder();
gestureBuilder.addStroke(new GestureDescription.StrokeDescription(clickPath, 0, 1));
dispatchGesture(gestureBuilder.build(), null, null);
I have also tried replaced the clickPath.moveTo to add clickPath.addCircle, and clickPath.addRect, But both of those just crash the application.

I know this question was a few months ago, but from what I've seen, your duration is too short. I wasn't able to get touch events to register with a duration of less than 50ms. I also passed a custom handler:
val handler = Handler(Looper.myLooper()!!)
It's possible that one or both of these could be the source of the reason it wasn't working for you. In general, you seem to be doing the same thing that I am, and I'm having some success with it.

How to open an application inside another application within the latters boundaries in android?

How to open an application inside another application within the latters boundaries in android? ie., similar to what iframe does in HTML.

You basically can't. It goes against the rules of Android. The most you can do is open a web page as part of an app. This is done using the webView. You can control the boundaries of the screen by setting the bounds of the webview in the xml file for the Webview.
public class WebViewFragment extends Fragment {
public static final String ARG_SECTION_NUMBER = "section_number";
public WebViewFragment() {
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View mainView = inflater.inflate(R.layout.fragment_facebook,
container, false);
WebView webView = (WebView) mainView.findViewById(R.id.webView1);
webView.setWebViewClient(new MyWebViewClient());
webView.getSettings().setSupportZoom(false);
webView.getSettings()
.setJavaScriptCanOpenWindowsAutomatically(true);
webView.getSettings().setAllowFileAccess(true);
webView.getSettings().setDomStorageEnabled(true);
webView.loadUrl(""); //URL needs to be entered in this line
return mainView;
}
}
Hope this helps :)

This is not possible because of security reasons. Previous versions of Android allowed this with System-grade permissions (ones that most developers will never get to use), but it was rarely used and is not in the SDK anymore as far as I know.
Some manufacturers implement additional functionalities like Samsung's Mini Apps (if I remember the name correctly) which may be opened in a floating window above other apps. You can also draw your own app over another using a service (like Facebook messenger does). But there is no way to force a third party app to do any of these things.
However, every time you open an application from your application, the process of the new one will have the invoker's process assigned as parent. This allows you, to some extend, check if this other app was opened from your app.
Also, your app will not die when opening a new one, but will simply be "below it". If you need some kind of data from the other app, you may start it forResult. This way the other app will "know" you are expecting a defined result from it, so it will process some data and pass it back to your app (which will reappear after the other one is finished preparing the result).

It could be possible if use the android property
android:launchMode="singleTask while declaring your activity in the AndroidManifest.xml (inside the activity element).
If you so so, if you minimize your app and launch it again (from background or from app icon from the list of apps), it would still show you the new app.
I am not sure if the result would be as per your desired effect.

Having application running above other app

I want to make an activity that can be opened above ANY app.
Normally, even when the activity is set as dialog, when you switch to my app, you see my app, and in the background you see the launcher:
BUT, I want the app will go above any app like this: (made in photoshop):
I did see this question Creating a system overlay window (always on top), but in ICS there is no functionallity to the layout.
Furthermore, I want to give a dialog box from my app without minimizing the other app...

there are plenty of apps that show a floating view on top of everything like : airbrowser , LilyPad , Stick it , AirTerm , Smart Taskbar , aircalc ...
anyway , in order to achieve this feature , you must have a special permission called "android.permission.SYSTEM_ALERT_WINDOW" , and use something like that:
final WindowManager.LayoutParams param=new WindowManager.LayoutParams();
param.flags=WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
final View view=findViewById(R.id.my_floating_view);
final ViewGroup parent=(ViewGroup)view.getParent();
if(parent!=null)
parent.removeView(view);
param.format=PixelFormat.RGBA_8888;
param.type=WindowManager.LayoutParams.TYPE_SYSTEM_ALERT;
param.gravity=Gravity.TOP|Gravity.LEFT;
param.width=parent!=null?LayoutParams.WRAP_CONTENT:view.getLayoutParams().width;
param.height=parent!=null?LayoutParams.WRAP_CONTENT:view.getLayoutParams().height;
final WindowManager wmgr=(WindowManager)getApplicationContext().getSystemService(Context.WINDOW_SERVICE);
wmgr.addView(view,param);
// TODO handle overlapping title bar and/or action bar
// TODO you must add logic to remove the view
// TODO you must use a special permission to use this method :android.permission.SYSTEM_ALERT_WINDOW
// TODO if you wish to let the view stay when leaving the app, make sure you have a foreground service running.

I'm one of the developers of the Tooleap SDK, and we also dealt with this issue.
Basically, you don't need to use the SYSTEM_ALERT_WINDOW to display an activity on top of another one. You can just display a regular "shrinked" Activity with a transparent background.
To make a "shrinked Activity, change the activity window layout params of height and width:
WindowManager.LayoutParams params = getWindow().getAttributes();
params.x = ...;
params.y = ...;
params.width = ...;
params.height = ...;
this.getWindow().setAttributes(params);
To make a transparent background add to your activity definition in the manifest file:
android:theme="#android:style/Theme.Translucent"
That way, you can create the illusion of a floating activity:
Note that only the foreground activity will be resumed, while the background one is paused. But for most apps this shouldn't be an issue.
Now all that remains is when to launch the floating activity.
Here is an example of a "floating" calculator app using a regular activity. Note that the activity below the calculator belongs to another app.

I want to run the application in background of mobile without any GUI in mobile using J2ME?

I am developing the network application in which I want to run my J2ME MIDP application in background without any GUI so that is any way to construct the application is such manner.

try this
set your current Display to null. so there will not be any form or alert running on the screen. But however your code will be running in the background.
Display display = Display.getDisplay(this); // here 'this' points to Midlet
display.setCurrent(null);

it easy just have a code of line on any event for example in the click of button
Display.getDisplay (this).setCurrent (null);
and return back the control via
Display.getDisplay (this).setCurrent (mycanvas);

Yes this code works Good,
display = Display.getDisplay(this);
public void startApp()
{
display.setCurrent(form);
}
public void pauseApp()
{
}
public void hide()
{
Display.getDisplay (this).setCurrent (null);
}
This is will work like, make a button can after clicking it call hide Function, or you call this hide function in constructor so it will hide itself when app start, can you keep unHide statement in appStart() so if you Tab the program then it will unHide app again.
NOTE: you said you are working on Network app, but some mobile will turn off the Internet Connection, when the Mobile screen Turn Off. please check this. and If you found any solution It will be Good to share here.

How to make a J2ME application run in Background?

I have a written a J2ME application which uses Bluetooth and search a file within the peer mobile and download it. I would like to make my application run in background , whenever I get a call , or message and later resume after few seconds , Has anybody worked on this please share your experience . Is there any way to run a Midlet in background ?

to set a j2me app to the background use the following in your midlet class:
Display.getDisplay (this).setCurrent (null);
to get the screen back use the following:
Display.getDisplay (this).setCurrent (myCanvas);
Where myCanvas is your canvas instantiation
R
p.s. You can still use a thread or timer to do things in the background while your midlet is hidden.
p.s.2: this does not work on all models. (Works on Nokia s60, SonyEricsson, but not on Nokia s40, Samsung and some others.

A device's ability to run an application in the background depends on its ability to multitask. Therefore, more expensive, PDA-type devices are more likely to support background execution than lower-cost devices.
For in background :-
private Display display = Display.getDisplay(this);
private Displayable previousDisplayable;
public void toBack() {
previousDisplayable = display.getCurrent();
display.setCurrent(null);
}
And to come in Fore ground :-
public void toFront() {
display.setCurrent(previousDisplayable);
}
But be aware that it not supports every device.(Works on Nokia s60, SonyEricsson, but not on Nokia s40, Samsung and some others).
