The android background process is full and the app restarts every time it enters the page

More common in Huawei mobile phones
such as Huawei P30

1. Add the following method to the base class BaseActivity:
 

@Override
    public boolean moveTaskToBack(boolean nonRoot) {
        return super.moveTaskToBack(true);
    }

2. Add code judgment in oncreate of App's startup page:
 

if (!this.isTaskRoot()) {
            Intent mainIntent = getIntent();
            String action = mainIntent.getAction();
            if (mainIntent.hasCategory(Intent.CATEGORY_LAUNCHER) && Intent.ACTION_MAIN.equals(action)) {
                finish();
                return;
            }
        }

Generally, it can solve the problem of reloading each time the app enters when more than 90% of the app processes occupy a large amount.
Scenario: The user jumps out through the notification bar or the Home button (checking text messages, etc.) and re-enters the app reloading problem.
