私はこの例外があります：

これは、次の2つの方法を示しています。
@Override
public void onStart(Intent intent, int startId) {
handleCommand(intent, startId); //TODO intent is null.
}
これはこのメソッドを呼び出し、nullインテントを送信します。
public void handleCommand(Intent intent, int startId) {
String action = intent.getAction(); //Exception happens right here when intent is null.
...
私が疑問に思っているのは、なぜインテントがかなり定期的にnullとして送信されるのかということです。それは私が自分のコードで正しく行っていないことであるに違いありません、そして問題の根本は他の場所にある可能性があります。
これはBillingRecieverコード全体です。
