Wi-Fiとセルデータの使用量を収集してSMSで送信するアプリを構築しています-これはすべて正常に機能しています。私の問題は、他のことをする前にデバイスから少なくとも 1 つの電話がかけられたことを確認する方法を実装しようとしていて、いくつかの問題が発生していることにあります。
エラー：
このメソッドは int 型の結果を返す必要があります
エラーの場所:
public int onStartCommand(Intent インテント、int フラグ、int startId、int 状態、String incomingNumber)
試行されたエラー解決:
return メソッドを追加 - 状態を返します。
試みられたエラー解決の問題:
return メソッドは既にあります
