The Android Activity Stack Stack Overflow I'm facing a problem in starting an activity in android. what am i doing? i have a setonclicklistner in signupactivity.class which calls a method called "dosignup" located in methodsparse.class. Because the activities in the back stack are never rearranged, if your app lets users start a particular activity from more than one activity, a new instance of that activity is created and pushed onto the stack, rather than bringing any previous instance of the activity to the top.
Startactivity Android Stack Overflow By following best practices and leveraging different types of intents, you can make the most out of the startactivity method—ensuring that your android application is not only functional but also provides an enjoyable user experience. Application, activity, service — three types of context, each with different lifetimes. using the wrong one is one of the most common sources of memory leaks in android. here's the rule of thumb that prevents 90% of mistakes. When a new activity is started, it is placed on the top of the stack and becomes the running activity the previous activity always remains below it in the stack, and will not come to the foreground again until the new activity exits. The startactivity(intent) method is used to start a new activity, which will be placed at the top of the activity stack. it takes a single argument, an intent, which describes the activity to be executed.

I've tried to setup a toast message in the onpause() method of the callee acitivty but it won't appear. If you haven't already done so: import android.app.activity; import android.content.intent; that will fix your "create startactivity" issue. Previous answers have revealed that the startactivity method itself ensures the relevant operations are run on the main thread, so it doesn't actually matter where you call it: is it safe to launch and activity from a non ui thread?. The flag activity no history flag keeps the new activity from being added to the history stack. nb: as @sam points out, you can use i.addflags(intent.flag activity no history); instead.
