One might be working on an Android application and integrating it with Facebook to share a story, image or a game point scored, to do that the first thing that you would like to know is if Facebook is really installed on the device or not.
⛏️ com.facebook.katana is the package name for the Facebook app on Android.
Let's see how we can do this by creating a single java method,
- Create a method say isFacebookInstalled() that returns a boolean.
- Get the PackageManager instance using getPackageManager()
- Now declare a boolean flag and set it to false by default.
- In a try and catch block look for the package for Facebook: com.facebook.katana
- If it throws an exception then we do not have this package installed, just turn a false in this case.
You can create a method as below and check if the user has Facebook installed or not,
public Boolean checkFbInstalled() {
PackageManager pm = getPackageManager();
boolean flag = false;
try {
pm.getPackageInfo("com.facebook.katana", PackageManager.GET_ACTIVITIES);
flag = true;
} catch (PackageManager.NameNotFoundException e) {
flag = false;
}
return flag;
}
⛏️ Facebook is known via various package names as well, you can try using one of these,
- com.example.facebook
- com.facebook.katana
- com.facebook.orca
- com.facebook.android
⚠️ If you are integrating Facebook SDK with your application you may really not need to do this as the SDK framework can handle this.
