to get a current screen view from my own application

Question

I am running one external application from my own application and when this application opens, i want to get a view of that external application in my own application. So that i can capture a screenshot of it. Please help me in this.

Answer 1

I dont think thats possible. The communication between applications or even activities is limited to passing data to each other through intents. I don't think sharing references to objects across applications is possible. Please correct me.

Such a thing would be possible if they allowed you to launch an external application in your own window.

Answer 2

I did some search and it is quite likely it may not be possible, however I have found a possible way. Take a look at this link, which states that

Or If you want to take a ScreenShot of your current device screen (any application) then you have to root permission, and read framebuffer for that which will give raw data of current screen then convert it to bitmap or any picture file you can do it in your service.

Which means that whenever your application starts an application you will need to create a service that reads the framebiffer, but if an activity is used for taking the screenshot then it will not be useful because the screenshot will then be of that activity.

See this and this, these links are related to your question as well. And see if it works.

Hope this helps.
