I am seeing every answer here says to override the onResume() method. This is a bad idea. Why? Well, when you are in the MainActivity and you get a call, you can still see the activity in the background, as it is in the onPause() state. When you dismiss the call, onResume() will be called and then SplashActivity will be called. This is not a good user experience and not what you might be looking for.

Also, onResume() gets called during the creation of MainActivity. So if you put the startActivity() code in onResume() without any conditional check, you will never see MainActivity itself. SplashActivity will start immediately when MainActivity is created.


So, how to accomplish what you want?

  1. Once you start MainActivity from SplashActivity, don't finish() the SplashActivity. Let it remain in the back stack, so when you press back button, you will go to SplashActivity.

  2. In the onStop() method of your MainActivity set a flag to note that MainActivity is minimized. Then in onStart() check for this flag and start SplashActivity only if this flag is set. This is to make sure that the app is minimized and is resuming.

MainActivity:

 private boolean isMinimized = false;

 @Override
 protected void onStop() {
      super.onStop();
      isMinimized = true;
 }

 @Override
 protected void onStart() {
      super.onStart();

      if(isMinimized){
          startActivity(new Intent(this , SplashActivity.class));
          isMinimized = false;
          finish();
      }
 }

  1. For home button pressed

Use Home as category in intent-filter of your SplashScreen AndroidManifest.xml file

<intent-filter>
 ....
 //-- this will show up your app when home button pressed (like laucher)
 <category android:name="android.intent.category.HOME" />
</intent-filter>
  1. For Back button pressed

Override them with intent to Splash Screen

@Override
public void onBackPressed() {
    startActivity(new Intent(this , SplashActivity.class));
    finish();
}

  1. OnResume

    Before coming to running state OnResume is called according to this so if you called some other activity at onResume current will not even start it will directly do to intent declared,

Try this code inside your MainActivity 

@Override
    protected void onResume() {
        super.onResume();
        startActivity(new Intent(this , SplashActivity.class));
        finish();
    }

Edit You can use flag to detect the first time when onResume is called

int flag = 0;

and change your onResume code to below :

@Override
    protected void onResume() {
        super.onResume();
        if(flag == 0) {
            flag = 1 ;
        }
        else {
            flag = 1 ;
            startActivity(new Intent(this, SplashActivity.class));
            finish();
        }
    }

If you don't finish your Activity before starting the new one you will get back to the Splash Activity on back press.

Override OnResume and start your splash Activity for starting it from splash whenever application is resumed.

@Override
protected void onResume() {
    super.onResume();
    startActivity(new Intent(this , SplashActivity.class));
    finish();
}

Just like this ...
