Android - コールログ/履歴：ネットワークカバレッジがない場合はダイヤル番号を取得する -- call-history フィールド android 関連 問題

I dialed a number when I had no network support but it does not appear in the call history of my android phone.

Is there any way to get it ? (system logs or whatever)

THanks a lot in advance, Jack

Your phone deals with three types of calls: incoming, outgoing or missed. As you can see from the API documentation.

Technically speaking, you've typed some digits, but since you had no network coverage, you didn't actually place any call. So, there was no reason to log anything, or even a way to classify those digits as a valid outgoing call.

Android has a database to store all the calls made, but they must match one of the above three types, and as you can see here the existent fields on the database don't contemplate the possibility of rows for every collection of digits typed that doesn't fit the parameters of a call (duration, type, etc..).
