After the splash screen, it takes about 6 sec to load onCreate contents in the Main activity. So I want to show a progress dialog while loading and here's what I did:

import ...

private ProgressDialog mainProgress;

public void onCreate(Bundle davedInstanceState){
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);

    mProgress = new ProgressDialog (Main.this);
    mProgress.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
    mProgress.setMessage("Loading... please wait");
    mProgress.setIndeterminate(false);
    mProgress.setMax(100);
    mProgress.setProgress(0);
    mProgress.show();

    ---some code---

    mProgress.setProgress(50);

    ---some code---

    mProgress.setProgress(100);
    mProgress.dismiss();
}

and it doesn't work... the screen stays black for 5-6 sec and then load the main layout. I dont know which part I did wrong :*(

You need to do start your busy code in an other thread (than the UI thread). In your activity create the ProgressDialog and close it in the thread

mProgress = new ProgressDialog (Main.this);

Runnable runnable = new Runnable() {
    @Override
    public void run() {
        // code that needs 6 seconds for execution

        // after finishing, close the progress bar
        mProgress.dismiss();
    }
};

new Thread(runnable).start();

ProgressDialog Tutorial With Example In Android Studio, onCreate(savedInstanceState); setContentView(R.layout.main); activity = this; progDailog = ProgressDialog.show(activity, "Loading","Please wait", true);  So, let’s say I must accomplish several tasks before giving the user the ability to use the main activity.

I personally would not use a progress dialog in this case, but rather have a progress indicator on each of the grid items while the images are loading. But if you really want a progress dialog, you have to, as I mentioned before, implement some logic in your Adapter which tells you when an Item is loaded.
