When using Floating Bubble as a Background Service to take a screenshot of Live Screen. Getting two Errors

Question

enter code here BackgroundService-

    private void addNewBubble ()//ERROR , Expression expected and Missing ';' token{


        windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
        //here is all the science of params
        final WindowManager.LayoutParams myParams = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
                WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                        | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
                        | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
                PixelFormat.TRANSLUCENT
        );
        BubbleLayout bubbleView = (BubbleLayout) LayoutInflater.from(BackgroundService.this).inflate(R.layout.bubble_layout, null);
        bubbleView.setLayoutParams(myParams);

        bubbleView.setOnBubbleRemoveListener(new BubbleLayout.OnBubbleRemoveListener() {
            @Override
            public void onBubbleRemoved(BubbleLayout bubble) {
            }
        });
        bubbleView.setOnBubbleClickListener(new BubbleLayout.OnBubbleClickListener() {

            @Override
            public void onBubbleClick(BubbleLayout bubble) {


                Bitmap b = Screenshot.takescreenshotOfRootView(imageView);
                imageView.setImageBitmap(b);
                main.setBackgroundColor(Color.parseColor("#999999"));

                //Toast.makeText(getApplicationContext(), "Clicked !",
                //   Toast.LENGTH_SHORT).show();
            }
        });
        bubbleView.setShouldStickToWall(true);
        bubblesManager.addBubble(bubbleView, 60, 20);
    }
}

private void initializeBubblesManager() {
    bubblesManager = new BubblesManager.Builder(this)
            .setTrashLayout(R.layout.bubble_trash_layout)
            .setInitializationCallback(new OnInitializedCallback() {
                @Override
                public void onInitialized() {
                    addNewBubble();// ERROR
                }
            })
            .build();
    bubblesManager.initialize();
}

}

This is the OnStart method which includes all the methods to create the floating bubble and to make it clickable to take a screenshot. Only addNewBubble is showing errors , whereas when the Floating Bubble code is run on the MainActivity without the creation of BackgroundService it runs fine without any errors. Any suggestions as to what to do ?

I am new to stackoverflow , please help me. I have checked here and cant seem to find a similar error. — Yohanelly, Sep 20 '17 at 18:54

Yes I have read this , the error is similar. But my code is drastically different , I have used compile 'com.txusballesteros:bubbles:1.2.1' — Yohanelly, Sep 20 '17 at 19:22
Hi Yohanelly, Stack Overflow isn't just a technical support forum. Show us specifics. Anyway, you might want to look [here](https://stackoverflow.com/questions/7569937)? — Nadav S., Sep 20 '17 at 21:13
Yes thank you , but i have added the android.permission.SYSTEM_ALERT_WINDOW in the manifest. Is there any other solution? — Yohanelly, Sep 21 '17 at 05:26
Sorry guys I am new to android studio , I keep getting down voted. I dont mean to be so naive. Im sure this is a silly error to you guys. Id really appreciate some patience and help. Thank you — Yohanelly, Sep 21 '17 at 07:06
hey @Yohanelly , please can you share a source code on how you were able to resolve ? — Ayodele Kayode, Dec 03 '20 at 21:37

Thank you so much , the application opens now. Although , the first time I opened it , it worked perfectly.I closed the app and ran it again. The app opens but the ADD BUBBLE button does not create a bubble again. Did this happen when you ran it? — Yohanelly, Sep 21 '17 at 10:35
I forget to do the else part in checkDrawOverlayPermission(), I have edited the code .. just check it — Saneesh, Sep 21 '17 at 10:41
So I used another emulator. Ive realized , it works the first time since when the app opens the first time it asks for permission. Then the bubble is created. However , opening the app for the second time , it does not ask for permission and so the app opens but the Add bubble button does not create a new bubble. Any way around this ? — Yohanelly, Sep 21 '17 at 10:45
My apologies. It works. Thank you being so helpful and more importantly thanks for being so patient with me. — Yohanelly, Sep 21 '17 at 10:49
Hey @Saneesh so OnBubbleClick i want to take a screenshot of the view , Instead of showing a Toast message. Do you have any suggestions? — Yohanelly, Sep 21 '17 at 11:23
Refer this one: https://stackoverflow.com/questions/2661536/how-to-programmatically-take-a-screenshot-in-android — Saneesh, Sep 21 '17 at 11:35
Thsnk you , but this seems a little confusing. I want to make my bubble take a screenshot of the live screen. It doesnt matter if it is saved to the sd card or not. Can you please help me out if you have the time? — Yohanelly, Sep 21 '17 at 13:42
I am now able to take a screenshot. But the screenshot only works within the application activity. I need to take a live screenshot. I need to create a background service which displays the floating bubble using the window manager. But being a novice, this task seems quite tough. Could you help me out? @Saneesh — Yohanelly, Sep 21 '17 at 15:58
Hey I have come a long way since you last saw my code. I have created a background service and add all the bubble code to the OnStart() method. And only the permissions code remains in the MainActivity. Inside the checkDrawOverlayPermission() else statement I have put startService(new Intent(this, BackgroundService.class)); — Yohanelly, Sep 22 '17 at 07:54
But I am getting only two errors. They seem simple enough to solve but I am Unable to do so. They are compile errors. Please could you have a look at the code? I will Edit the question and post the MainActivity and the BackgroundService code there. — Yohanelly, Sep 22 '17 at 07:55

Call addNewBubble() function in UiThread

runOnUiThread(new Runnable() {
      public void run() {
         addNewBubble()
      }
   });

like this.

Okay sir i will do that. But in which part of my MainActivity.java do i enter this code? – Yohanelly Sep 21 '17 at 08:54
findViewById(R.id.add).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { runOnUiThread(new Runnable() { public void run() { addNewBubble() } }); } }); – Saneesh Sep 21 '17 at 08:57
Thank you so much , i will update my app and let you know. I am currently downloading an sdk, Will update you as soon as it is done. – Yohanelly Sep 21 '17 at 09:11
My target sdk is 26. Is there anything else i can do ? Please help – Yohanelly Sep 21 '17 at 09:27
Should I send you a github link? Or what other way is there to show the manifest file , it is too long to post in the comments section. – Yohanelly Sep 21 '17 at 09:36
just post the users permission code in the question – Saneesh Sep 21 '17 at 09:38

Did that help ? This is the link to the updated MainActivity.java with the UiThread https://github.com/yohanelly/My-Application/blob/master/src/MainActivity.java – Yohanelly Sep 21 '17 at 09:54
