当使用Floating Bubble作为后台服务拍摄实时屏幕截图时。 遇到两个错误

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 ?

Answer 1

Call addNewBubble() function in UiThread

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

like this.
