Different Ways to Programmatically Restart an Android App on Button Click
Sometimes we want to refresh an Activity, but there it is not possible to refresh. In that place, if we restart our app then it automatically gets refreshed. Also, we can use this to restart our app whenever it crashes. Most of the time when we open any app then it fetches all the data currently available. But if in the meantime if more data is updated to the database then we can use this feature to restart to again fetch all data every time it gets new data.
Now the point that comes here is how we can Programmatically Restart an Android App on Button Click . So in this article, we are going to discuss three different methods to Programmatically Restart an Android App on Button Click.

Stopping and Restarting an Activity

Properly stopping and restarting your activity is an important process in the activity lifecycle that ensures your users perceive that your app is always alive and doesn’t lose their progress. There are a few of key scenarios in which your activity is stopped and restarted:
- The user opens the Recent Apps window and switches from your app to another app. The activity in your app that’s currently in the foreground is stopped. If the user returns to your app from the Home screen launcher icon or the Recent Apps window, the activity restarts.
- The user performs an action in your app that starts a new activity. The current activity is stopped when the second activity is created. If the user then presses the Back button, the first activity is restarted.
- The user receives a phone call while using your app on his or her phone.
The Activity class provides two lifecycle methods, onStop() and onRestart() , which allow you to specifically handle how your activity handles being stopped and restarted. Unlike the paused state, which identifies a partial UI obstruction, the stopped state guarantees that the UI is no longer visible and the user’s focus is in a separate activity (or an entirely separate app).
Note: Because the system retains your Activity instance in system memory when it is stopped, it’s possible that you don’t need to implement the onStop() and onRestart() (or even onStart() methods at all. For most activities that are relatively simple, the activity will stop and restart just fine and you might only need to use onPause() to pause ongoing actions and disconnect from system resources.
Figure 1. When the user leaves your activity, the system calls onStop() to stop the activity (1). If the user returns while the activity is stopped, the system calls onRestart() (2), quickly followed by onStart() (3) and onResume() (4). Notice that no matter what scenario causes the activity to stop, the system always calls onPause() before calling onStop() .
Stop Your Activity
When your activity receives a call to the onStop() method, it’s no longer visible and should release almost all resources that aren’t needed while the user is not using it. Once your activity is stopped, the system might destroy the instance if it needs to recover system memory. In extreme cases, the system might simply kill your app process without calling the activity’s final onDestroy() callback, so it’s important you use onStop() to release resources that might leak memory.
Although the onPause() method is called before onStop() , you should use onStop() to perform larger, more CPU intensive shut-down operations, such as writing information to a database.
For example, here’s an implementation of onStop() that saves the contents of a draft note to persistent storage:
When your activity is stopped, the Activity object is kept resident in memory and is recalled when the activity resumes. You don’t need to re-initialize components that were created during any of the callback methods leading up to the Resumed state. The system also keeps track of the current state for each View in the layout, so if the user entered text into an EditText widget, that content is retained so you don’t need to save and restore it.
Note: Even if the system destroys your activity while it’s stopped, it still retains the state of the View objects (such as text in an EditText ) in a Bundle (a blob of key-value pairs) and restores them if the user navigates back to the same instance of the activity (the next lesson talks more about using a Bundle to save other state data in case your activity is destroyed and recreated).
Start/Restart Your Activity
When your activity comes back to the foreground from the stopped state, it receives a call to onRestart() . The system also calls the onStart() method, which happens every time your activity becomes visible (whether being restarted or created for the first time). The onRestart() method, however, is called only when the activity resumes from the stopped state, so you can use it to perform special restoration work that might be necessary only if the activity was previously stopped, but not destroyed.
It’s uncommon that an app needs to use onRestart() to restore the activity’s state, so there aren’t any guidelines for this method that apply to the general population of apps. However, because your onStop() method should essentially clean up all your activity’s resources, you’ll need to re-instantiate them when the activity restarts. Yet, you also need to instantiate them when your activity is created for the first time (when there’s no existing instance of the activity). For this reason, you should usually use the onStart() callback method as the counterpart to the onStop() method, because the system calls onStart() both when it creates your activity and when it restarts the activity from the stopped state.
For example, because the user might have been away from your app for a long time before coming back it, the onStart() method is a good place to verify that required system features are enabled:
When the system destroys your activity, it calls the onDestroy() method for your Activity . Because you should generally have released most of your resources with onStop() , by the time you receive a call to onDestroy() , there’s not much that most apps need to do. This method is your last chance to clean out resources that could lead to a memory leak, so you should be sure that additional threads are destroyed and other long-running actions like method tracing are also stopped.
