Open my application from another in android

My boss asked me to prove that my application behaves properly when summoned by another application (dunno why he asked that).

So I have two apps here, one launches a second one. How I launch the specific app I want? Using Intent launch seemly any generic app that reaches a certain goal, not the app I really want.

Create one Intent using the following code

Explicit Intent

When you know the particular component(activity/service) to be loaded

Intent intent = new Intent();
intent.setClass("className/package name");

start<Activity/Service>(intent);

Imlicit Intent

When we do not have the idea which class to load and we know the Action to be perform by the launched application we can go with this intent.

Action needs to set, and the Android run time fallows the intent Resolution technique and list out(one or more components) the components to perform the action. from the list out components (if more than one), user will get the chance to launch his chosen application

Give this a try.

Intent secondIntent = new Intent();
secondIntent.setAction(Intent.ACTION_MAIN);
secondIntent.setClassName("com.example", "com.example.YourSecondApp");
startActivity(secondIntent);

I should point out that com.example should be the package of your second application (the one you want to call) and com.example.YourSecondapp is the class name where you have your onCreate() method.

Intent secondApp = new Intent("com.test.SecondApp");
startActivity(secondApp);
