Can not find Database File in Android but It can be deleted

This is supposed to be pretty easy but I'm not being able to find a SQLite file in my Genimotion emulator or in my mobile phone either.

The code is pretty simple:

private boolean ddbbFileExistsInMobile() {
    File f_ddbb_local = new File(DDBB_PATH, DataBaseHelper.DDBB_file);
    return f_ddbb_local.exists();
}

    if(android.os.Build.VERSION.SDK_INT >= 17){ // 17-> 4.2 Android
        DDBB_PATH = context.getApplicationInfo().dataDir + "/databases/";
    }
    else
    {
        DDBB_PATH = "/data/data/" + context.getPackageName() + "/databases/";
    }

if(ddbbFileExistsInMobile()) {
    File f_ddbb_local = new File(DDBB_PATH, DataBaseHelper.DDBB_file);
    f_ddbb_local.delete();
}

This last if allways returns false.

I also checked with this code afterwards, that the PATH is correct.

File dbFile = mContext.getDatabasePath(DataBaseHelper.DDBB_file);
String aux = dbFile.getAbsolutePath();
Log.d(LOG_TAG, aux);

I have really no clues what is happening. Why that file can't be found?

The most extrange thing is that I can delete it with this code:

f_ddbb_local = new File(DDBB_PATH, DataBaseHelper.DDBB_file);
f_ddbb_local.delete();

So if I delete it directly, it erased, but if I use the previous function: ddbbFileExistsInMobile() the program never goes into the if.
