can't go back to the previous activity

This is how my app opens a page in default browser
Intent i = Intent.parseUri("http://www.google.com", Intent.URI_INTENT_SCHEME);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
Once the browser activity is active, I can't navigate back to my app using back button. It goes the activity before my app. My app/activity is not destroyed though as I can still resume it from the app list. I suspect my activity is 'removed' from the back stack somehow. Please help me debug/fix this. Thanks.

try to use Intent.ACTION_VIEW
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(myUrl));
startActivity(intent);

Confusing behaviour with intents in Android

I call GooglePlay from my app through an intent and again after I kill my own app:
Intent intent = new Intent(Intent.ACTION_VIEW);
String sModule = "market://search?q=pub:mycompany";
intent.setData(Uri.parse(sModule));
startActivity(intent);
finish();
android.os.Process.killProcess(android.os.Process.myPid());
Task manager shows, that only GooglePlay is running. My app isn't there anymore.
So my focus is GooglePlay at the moment. When going to the Desktop through the Home-Button and calling my App again it directs me to GooglePlay again.
Why is that? How can I call GooglePlay from my app independently?
I expected that when starting my app again, which I had previously killed, it would start my app and not focus on google play.

keyword is "launchMode" and "task".
this type of problems are so annoying and much complicated in android.
but this time you can try this.
Intent intent = new Intent(Intent.ACTION_VIEW);
String sModule = "market://search?q=pub:mycompany";
intent.setData(Uri.parse(sModule));
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
finish();
if u cant solve, try combine another flags with FLAG_ACTIVITY_NEW_TASK.
cheers!

Close all activities and come to mobile's home screen

When I press the log out button and come to start(main) screen and when I press the back button from main screen it comes to 2nd screen. but, i want to close the application on click of back button from main screen and close all the activities before that.
while doing research I found,
Intent intent = new Intent(this, Home.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
finish();
but its not satisfying my requirement.

You can use this code that I referred from here How to exit from the application and show the home screen?:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
Although Android's design does not favor exiting an application by choice.

Need code for exit from app in android

Hello i am new to android.I am implementing some application and it have some activities.
Suppose if i launch the app for first time,it's entering in to A then going to B after that C,D,E..... (Here A,B,C,D,E are activities).If i press back button at E then it is going D--> C--> B--> A like this.
Now i want to implement code to exit/quit from the app when i am at D.
I wrote following code but this code is working for closing current activity and going to prev activity.means going C.
finish();
Then i tried with following code and it is working fine and closing current application successfully and going to device home screen.But if i want open the application again then it is starting form D instead of A.
intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
copied from here
Please help me to solve my problem.

Use these flags to lunch the activity and clear the activity stack
Intent intent = new Intent(this, YourActivityD.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
Be aware that FLAG_ACTIVITY_CLEAR_TASK is only available from API 11
See: http://developer.android.com/guide/components/tasks-and-back-stack.html

Try this:
finish();
System.exit(0);

Android killing applications

I have a login page and then a home page, then I have an exit button on the home page. When you press the exit, I need the app to close.
If I use finish() on the home page's exit onClick(),it just take me back to the login page.
So I am using
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
Now this does act like an exit but when you start the application again, it by passes the login screen and directly goes to the home page (as the app was never closed).
What would be the best solution here?

What would be the best solution here?
The best solution would be to delete the exit button and its associated functionality.
First, it is not necessary, as what you are providing with the exit button is already provided via the HOME button on the device.
Second, you have been told, repeatedly, by Googlers, not to have such a button.

Before Coming to HomePage from Login Page use finish();
Intent i = new Intent(Login.this, Home.class);
StartActivity(i);
finish();
