If you are getting the above error message in your Android Studio then the reason is that you have not specified the application Id in your AndroidManifest.xml file.

Also check that if you are using FacebookContentProvider to share something then you must provide the app id in com.facebook.app.FacebookContentProviderXXXXXXXXXXXXXXX :

provider android:authorities="com.facebook.app.FacebookContentProviderXXXXXXXXXXXXXXX"
            android:name="com.facebook.FacebookContentProvider"
            android:exported="true"/>

Also check that your key hash is correct, if not generate by calling this function in onCreate() method of your Activity.

private void getFbKeyHash(){
      PackageInfo info;
      try {

          info = getPackageManager().getPackageInfo(
                  "your.package.name", PackageManager.GET_SIGNATURES);

          for (Signature signature : info.signatures) {
              MessageDigest md;
              md = MessageDigest.getInstance("SHA");
              md.update(signature.toByteArray());
              String hashString = new String(Base64.encode(md.digest(), 0));
              System.out.println("App KeyHash : " + hashString);
          }
      } catch (Exception e) {
          Log.e("exception", e.toString());
      }
  }
