Answer 1

use my method if you want to start a hidden app for just first time I make a transparent Launcher activity like this

So I make the app hidden in launcher by placing this code in oncreat() [Code]

PackageManager p = getPackageManager();
    ComponentName componentName = new ComponentName(this, MainActivity.class); // activity which is first time open in manifiest file which is declare as 
p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

So I use this code for show app icon on launcher and make it run able on service class that use broadcast receiver boot and in network connection broadcast receiver class too(autostart.java and networkConnectinCheck.java):

PackageManager p = context.getPackageManager();
    ComponentName componentName = new ComponentName(context, MainActivity.class);
    p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);

Now I can run app for first time by user hands and after this I use my receiver's to lunch app any time.
