Log.d not showing log.d in Logcat Android Studio
提问by P.Yntema
Android studio does not show any Logs I wrote in my code. I have tried putting the log to verbose and debug. I am using 'No filters'. Why is 'Oncreatetestlog' not showing up in my logcat?
Android Studio 不显示我在代码中编写的任何日志。我尝试将日志放入详细信息并进行调试。我正在使用“无过滤器”。为什么“Oncreatetestlog”没有出现在我的 logcat 中？
package com.example.keydown;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState != null) {
Log.d("Oncreatetestlog", "onCreate() Restoring previous state");
/* restore state */
} else {
Log.d("Oncreatetestlog2", "onCreate() No saved state available");
/* initialize app */
}
}
}

Go to File -> invalidate caches / Restart. And let Android Studio to index your project again. It works for me.
转到文件-> 使缓存无效/重新启动。并让 Android Studio 再次索引您的项目。这个对我有用。

Alternatively, you could use System.out.println()to show the text in logcat
或者，您可以使用System.out.println()在 logcat 中显示文本
Replace
代替
Log.d("Oncreatetestlog", "onCreate() Restoring previous state");
With
和
System.out.println("Oncreatetestlog onCreate() Restoring previous state");

If Log.d is not showing in your Logcat just replace Log.dwith Log.wtfLike this:
如果 Log.d 未显示在您的 Logcat 中，只需替换Log.d为Log.wtf如下所示：
Replace:
代替：
Log.d("tag",""+catstr);
With:
和：
Log.wtf("tag",""+catstr);
It Works..happy coding;)
它有效..快乐编码;)
