2021年4月27日 · ELI5: it is a mathematic equation that tells us how many of one number we need to multiply to get another number. The Log of 8 with base of 2 is 3 ( log₂(8) = 3 ). This link explains it far better than me: https://www.mathsisfun.com/algebra/logarithms.html

Log.e: This is for when bad stuff happens. Use this tag in places like inside a catch statement. You know that an error has occurred and therefore you're logging an error. Log.w: Use this when you suspect something shady is going on. You may not be completely in full on error mode, but maybe you recovered from some unexpected behavior.

Log.wtf() will log an error with priority level ASSERT, and may (depending on the system configuration) send an error report and terminate the program immediately. It's made very clear in the API docs that WTF stands, in this case for "What a Terrible Failure".

In general, you write log followed by the base number as a subscript. The most common logarithms are base 10 logarithms and natural logarithms; they have special notations. A base ten log is written. So, when you see log by itself, it means base ten log. When you see ln, it means natural logarithm (we'll define natural logarithms below).

log(100) This usually means that the base is really 10. It is called a "common logarithm". Engineers love to use it. On a calculator it is the "log" button. It is how many times we need to use 10 in a multiplication, to get our desired number.

2020年9月21日 · 通过对Log.v与Log.d等不同日志级别的对比解析，本文揭示了它们在不同场景下的使用方法和特点，并强调了选择合适日志级别的策略。此外，文章探讨了在Android Studio中使用Lo

2022年12月27日 · Log.wtf() 将记录优先级为 ASSERT 的错误，并且可能（取决于系统配置）发送错误报告并立即终止程序。 Log.wtf () 可能会调用 onTerribleFailure () 并可能导致您的应用程序终止。 Log.e() 优先级为 ERROR 的日志。 但是， Log.wtf() 优先级为 ASSERT 的日志。 但是 源代码 与上述信息 冲突。 TerribleFailure what = new TerribleFailure(msg, tr);

2023年9月21日 · The logarithmic time complexity, O (log n), means that as the input size (n) grows, the number of operations doesn't grow linearly but grows in a logarithmic scale. This is why algorithms with logarithmic time complexity are efficient.

2016年1月7日 · Log.wtf() 对应 ASSERT级别. There is a difference in severity; Log.e() will simply log an error to the log with priority ERROR. Log.wtf() will log an error with priority level ASSERT, and may (depending on the system configuration) send an …

2016年4月9日 · In android development there are different logging levels. For example, there is Log.v for verbose, Log.e for level error, Log.w for level warn. All these are visible in logcat during development. Then there is Log.wtf which is like Log.e except it has level Assert which may actually terminate the program depending on the system.
