How to run existing Android application from others, or create launcher

This is script to make a launcher or call another android app from others.

PackageManager pm=getPackageManager();

Intent intent=pm.getLaunchIntentForPackage(“com.yourcompany.package_name”));

if (intent!=null){

   startActivity(intent);

}

If you run from a fragment, you must add Context before you get a PackageManger, and the script is :

PackageManager pm=mContext.getPackageManager();

Intent intent=pm.getLaunchIntentForPackage(“com.yourcompany.package_name”));

if (intent!=null){

   mContext.startActivity(intent);

}

Let’s try for your own Android application.
