How to get app details from receiving intent?

Question

My app receives and analyze data from received intent (ACTION.SEND). Intent has many details in extras depending upon the application.

What I want is packageID of application from which my has received the intent?

Is there any standard way to achieve this?

Answer 1

If you need this application details in many activities of your application, you could save them into the Shared preferences and use them from all of the activities without passing them each time as extras in an intent. You could do it this way for example:

SharedPreferences.Editor editor = getSharedPreferences(preffName, MODE_PRIVATE).edit(); //preffName is a String variable with the name of your preferences - just use the same string every time 
editor.putString("AppName", "MyApplication");
editor.putInt("PackageID", "MyPackageID");
editor.commit();

And then you could get the saved data like this:

SharedPreferences prefs = getSharedPreferences(preffName, MODE_PRIVATE); 
String appName = prefs.getString("AppName", "No name defined");//"No name defined" is the default value.
String packageID = prefs.getString("PackageID", "No package id is defined."); //"No package id is defined" is the default value

After reading this How to find Intent source in Android? it seems impossible or very tricky solution. There is no direct way to achieve this. Ahh Android.
