私のAndroidアプリは電話のSQLiteDatabaseを利用しています. アプリのある時点でクラッシュすると、データベースが永久にロックされているため、突然多くのページ/フラグメントが機能しなくなるようです。

他の機能へのアクセスを再開できるように、手動でロックを解除/問題を解決する方法はありますか? 同じコードが他の友人の電話でも機能するため、デバッグを再度続行するには、自分の電話でデータベースのロックを手動で解除する必要があると思います。

以下は私の（編集済み：FULL）logcatです。

これが発生する理由は、データベースへの接続を一度に 1 つしか開くことができないためです。Db接続を閉じていないか、書き込みしようとしているときにスレッドがすでにDbに書き込んでいると思います。

1 つの SQLOpenHelper から db にアクセスすることをお勧めします (この例を参照してください)。

アプリケーションを閉じる (またはシステムがアプリケーションを強制終了する) と、データベースへの接続が切断され、クリーンアップされます。したがって、「永久にロックされる」ということはありません。

この問題は通常、スレッドがデータベースにアクセスしようとしているが、別のスレッドがロックを持っているか、それを使用していることに起因します。解決策: アプリケーションでデータベースへの接続のインスタンスを 1 つだけ使用します。1 つのアプローチは、インスタンスをサブベッド化された Application クラスに格納することです。
