How to check if Facebook is installed Android

Solution 1:

com.facebook.android is the package name for the Facebook SDK. The Facebook app's package is com.facebook.katana.

Solution 2:

To check whether or not an app is installed on Android use this method:

public static boolean isPackageInstalled(Context c, String targetPackage) {
    PackageManager pm = c.getPackageManager();
    try {
        PackageInfo info = pm.getPackageInfo(targetPackage, PackageManager.GET_META_DATA);
    } catch (NameNotFoundException e) {
        return false;
    }
    return true;
}

In your case use any of these packages:

• com.facebook.orca
• com.facebook.katana
• com.example.facebook
• com.facebook.android

boolean hasPackage = isPackageInstalled(MainActivity.this, "com.facebook.katana");

• For Kotlin

    fun isPackageInstalled(packageName: String, context: Context): Boolean {
       return try {
                val packageManager = context.packageManager
                packageManager.getPackageInfo(packageName, 0)
                true
            } catch (e: PackageManager.NameNotFoundException) {
                false
            }
        }
  

Solution 3:

 if (isAppInstalled()) {
        Toast.makeText(getApplicationContext(), "facebook app already installed", Toast.LENGTH_SHORT).show();
    } else {
        Toast.makeText(getApplicationContext(), "facebook app not installing", Toast.LENGTH_SHORT).show();
    }



public boolean isAppInstalled() {
            try {
                getApplicationContext().getPackageManager().getApplicationInfo("com.facebook.katana", 0);
                return true;
            } catch (PackageManager.NameNotFoundException e) {
                return false;
            }
        }
