android preload process implementation method

1. Background

When doing a reader independent process, open the reader reading page whereActivity, white or black screen will appear

That is to say, from a processactivityJump to another processactivity, white or black screen will appear

,Because it takes a long time to open an independent process, the solution is

Preload the process before jumping, thus avoiding the time to start the process

Select invisible components for preloading, such asService,broadcast

2. Realization

1. Create a preloaded service class

public class PreloadProgressService extends Service {
    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
}

2. Register and formulate in the list file

android:processThe process to be preloaded

<service
    android:name="."
    android:exported="true"
    android:process=":eink"
    />

3. Turn on and stop

a. Open the preload process

private void startPreloadProgressService() {
    if(!()){
        Intent intent = new Intent(requireActivity(), );
        requireActivity().startService(intent);
    }
}

b. Stop the preload process

private void stopPreloadProgressService(){
    if(()){
        Intent intent = new Intent(requireActivity(), );
        requireActivity().stopService(intent);
    }
}

c.Judgement of whether the process has been opened

public static boolean isServiceStart(Class<?> serviceClass) {
    ActivityManager manager = (ActivityManager) (.ACTIVITY_SERVICE);
    for ( service : (Integer.MAX_VALUE)) {
        if (().equals(())) {
            return true;
        }
    }
    return false;
}
