androidStudio 日志不起作用

Question

I cannot get log to work on my phone. I only get this error in Android Studio:

11-01 03:28:56.427 24227-24375/com.example.segall.caveofprogcourse E/GED: Failed to get GED Log Buf, err(0)

Android studio 2.1.3
Ubuntu 16.04 LTS
Sony Xperia M5
android 6.0 api 23

I have USB Debugging on.

Edit

This code in onCreate method

Log.d("mylog", " LOG WORKS ");  
Log.e("mylog", "onCreate called really?"); // I added this Log

gets the following results:

11-01 21:51:23.561 7820-7820/com.example.segall.caveofprogcourse E/mylog: onCreate called really?  
11-01 21:51:23.619 7820-7873/com.example.segall.caveofprogcourse E/GED: Failed to get GED Log Buf, err(0)

surprisingly, the Log.e works. Anyone know why this might have happened?

Edit 2 I created new project only with two logs in onCreate

    Log.d("mylog","Log.d on create this  is not working");
    Log.e("mylog","Log.e surprisingly this works");

I put a few empty line so it's easy to spot

screen of logcat

Answer 1

1. Try to don't use filter on the top right of logcat
2. Re-check your device is connected and logcat listen to the correct device
3. Choose log type verbose
4. You may need to download the configuration file from developer console and add it to your project. Second step of this link.File name is google-services.json
5. check your lib configuration especially Firebase config.

Answer 2

I had the same problem. Please update your Android Studio. It was a bug

Answer 3

With Linux(Ubuntu), you have Set up your system to detect your device. You may check theseGoogle guidelines

You need to add a udev rules file that contains a USB configuration for each type of device you want to use for development.

Before doing this, Verify that your application is "debuggable" in your manifest or build.gradle file.

 android {
        buildTypes {
            debug {
                debuggable true
            }

In the AndroidManifest.xml file, add android:debuggable="true" to the <application> element.

Now set up your system to detect your device using a udev rules file. Add a udev rules file that contains a USB configuration for each type of device you want to use for development. In the rules file, each device manufacturer is identified by a unique vendor ID, as specified by the ATTR{idVendor} property. So you have to know Sonys vendor id in your case: 054c

1. Log in as root and create this file: /etc/udev/rules.d/51-android.rules

ie

sudo gedit /etc/udev/rules.d/51-android.rules

Use this format to add each vendor to the file: 054c is sonys vendor id.

SUBSYSTEM=="usb", ATTR{idVendor}=="054c", MODE="0666", GROUP="plugdev"

If you add SUBSYSTEM=="usb", ATTR{idVendor}=="054c", MODE="0666", GROUP="plugdev" Android studio will detect Sony.

2. Now execute: chmod a+r /etc/udev/rules.d/51-android.rules

Close and start Studio. Then run run your project. Studio will detect it
