Sir,
The last opened activity will be saved and when opening the app, the last opened activity will be opened. But app reopen every time then see splash screen then go last open activity, Please help me for it..
Please send this code
That's simple. When the activity is closed, in the activity class, override the onStop() method and save the activity name in the SharedPreferences. Then in the main activity, get the SharedPreferences variable and open the activity using an intent. Hope this helps. For more info, ping using a comment. I'll share the working code.

I'm working on an application that connects to a server on a computer, it's about sharing a clipboard, links, etc. I added the activity responsible for sending to the sharing menu so you can send links directly from the browser and here is the problem.
When user select my app I want the activity to be created, sent a link and returned to the browser but without finishing activity.
I want to achieve an effect similar to open recent apps list and select previous app but programmatically.
I tried finish() and onBackPressed() but they close the activity
Finish() will close the activity, as it is it's role. But onBackPressed() should just call onPause. If the activity is killed by onBackPressed() (you should check if onDestroy() is actually called by, for example, overriding it and printing something), then it's possible that you are assigning a flag during the creation of activity that forces it to close later. Can you provide the code that shows the part where you create your activity?
I'm trying to make an Android app that has a Onboarding Screen that should teach the user how to use the app. I want to show this screen only the first time the app is opened. My Main Activity have a Navigation Drawer with fragments(recyclerview) and this screen should be shown as launcher once the Onboarding screen was already seen or isn't the first time that the app is opened.
So, the question is: what activity I should select as Launcher in the manifest?
P.S.:Sorry about my bad english in advance.
There are different approaches to do that. You can create an Activity without layout and name it DispatcherActivity. Make this activity as launcher activity.
You can then use SharedPreferences to determine if this first launch or subsequent launch (store a boolean isFirstLaunch, set it to true as soon as OnboardingScreen is launched) in onCreate of this activity. If its first launch, then start the OnboardingActivity else start your MainActivity.
I have an Android activity which checks if the user's GPS is turned on and gives the choice to go Settings to turn it on if it's off. However, when I return from Settings and pop my activity from back stack, I want onCreate() to run again and execute code which uses my location. I have tried running recreate() in the onResume() method, however in that case it will not load my activity at all.
Any suggestions on how to execute this task are welcome. Thank you.
when you moved from activity to settings then, Activity will go to onStop(). So, you can call onRestart() method in onStop() method will resume your Activity. Hope this option will help.
Or if this link is your case then u can find answer on same page.
How can I return back to my Activity from GPS settings window
Let's say the user presses a button which causes another activity to get launched. Now the user is in another activity. What flag do I have to add to the intent, so that the user returns to my app when pressing the back button instead of navigating down the back stack of the started activity?
From the documentation, "activities on the backstack are never rearranged."
Android documentation Tasks and BackStack
You do not have to add anything to the intent. When you navigate out of you app and start another activity to complete a task, the new activity becomes kind of like an extension of your app. Pressing the back button takes you back to your app. Read This
How would i resume the last viewed activity after the user has been closed the application. It is like, If the user open the application, the first activity will appear and when the user click the button it will proceed to the next activity, if he close the application and open again it will still show the last viewed activity. how would i do that? please help me.
Thank you,
I think you should use sharedpreferences. And in every activity you open, you have to put a value on your sharedpreference so that if you open again your application it will check the value of your shared preference then compare it, call the activity that fits the value you got. Hope it helps :)
You need to track his last activity then, keep it in a database and whenever he returns, look up his last activty in the database...the other way is cookies but not adviseable ....
Place this below line in AndroidManifest.xml for your activities in <activity/>.
android:launchMode="singleTask"
