androidStudio 日志不起作用

Question

我無法在我的手機上獲取日志。 我只在 Android Studio 中收到此錯誤：

11-01 03:28:56.427 24227-24375/com.example.segall.caveofprogcourse E/GED：無法獲得 GED 日志緩沖區，錯誤（0）

安卓工作室 2.1.3
Ubuntu 16.04 LTS
索尼 Xperia M5
安卓 6.0 API 23

我打開了 USB 調試。

編輯

onCreate 方法中的此代碼

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

得到以下結果：

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)

令人驚訝的是，Log.e 有效。 有誰知道為什么會發生這種情況？

編輯 2我在 onCreate 中僅使用兩個日志創建了新項目

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

我放了一些空行，所以很容易發現

logcat的屏幕

Answer 1

1. 盡量不要使用 logcat 右上角的過濾器
2. 重新檢查您的設備是否已連接並使用 logcat 監聽正確的設備
3. 選擇日志類型詳細
4. 您可能需要從開發者控制台下載配置文件並將其添加到您的項目中。 此鏈接的第二步。文件名是 google-services.json
5. 檢查您的 lib 配置，尤其是 Firebase 配置。

Answer 2

我有同樣的問題。 請更新您的 Android Studio。 這是一個錯誤

Answer 3

使用 Linux(Ubuntu)，您已設置系統以檢測您的設備。 您可以查看這些Google 指南

您需要添加一個udev rules文件，其中包含要用於開發的每種類型的設備的USB configuration 。

在執行此操作之前，請驗證您的應用程序在您的清單或build.gradle文件中是“可調試的”。

 android {
        buildTypes {
            debug {
                debuggable true
            }

在AndroidManifest.xml文件中，將android:debuggable="true"到<application>元素。

現在設置您的系統以使用udev 規則文件檢測您的設備。 添加一個 udev 規則文件，其中包含要用於開發的每種類型的設備的 USB 配置。 在規則文件中，每個設備制造商都由唯一的供應商 ID 標識，由ATTR{idVendor}屬性指定。 所以你必須知道你的案例中的索尼供應商 ID： 054c

1. 以 root 身份登錄並創建此文件： /etc/udev/rules.d/51-android.rules

即

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

使用此格式將每個供應商添加到文件中：054c 是 sonys 供應商 ID。

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

如果添加SUBSYSTEM=="usb", ATTR{idVendor}=="054c", MODE="0666", GROUP="plugdev" Android studio 會檢測到 Sony。

2. 現在執行： chmod a+r /etc/udev/rules.d/51-android.rules

關閉並啟動 Studio。 然后運行運行你的項目。 Studio 會檢測到它
