ログツールクラスL.java
これはログツールクラスで、とても使いやすいです!共有して、機能をサポートします各種レベルのlogログを出力する:v、d、i、e
L.v(「msg」)はtagのログ出力を持たず、現在位置するファイル、方法、行数を印刷することができる.L.vt(「tag」,「msg」)はtagのログ出力をカスタマイズする.
jsonデータのフォーマット
L.json(「json_string」)はtagのjsonログ出力を持たない.L.jsonT(「tag」,「json_string」)tag付きjsonログ出力;
Applicationでは、パッケージ化時に自動シールドlog出力 が構成する.
コードは次のとおりです.
