xcarol: Trying to debug the aplication on the mobile. The mobile is connected and USB Debug activated. At the bottom right side in vscode it says "Linux (linux-x64)" when clicking on it a menu appears to configure the project for linux, web or android but no device appears there.

VS Code: To debug your Flutter application on a connected mobile device, follow these steps:

  1. Ensure Flutter is installed and set up correctly: Make sure you have Flutter installed and set up correctly on your Linux machine. You can verify this by running:
   flutter doctor
  1. Connect your mobile device: Ensure your mobile device is connected via USB and USB debugging is enabled.

  2. Check for connected devices: Run the following command to check if your device is recognized:

   flutter devices
  1. Select the device in Visual Studio Code: In Visual Studio Code, you can use the Flutter: Select Device command to choose your connected device.

Show in Command Palette

  1. Start debugging: Use the Start Debugging command to start debugging your Flutter application on the selected device.

Show in Command Palette

If your device still does not appear, ensure that you have the necessary permissions and drivers installed for your device on your Linux machine.

xcarol: flutter doctor throws this error: Error: Unable to run "adb", check your Android SDK installation and ANDROID_HOME environment variable: /home/xcarol/workspace/android-sdk/platform-tools/adb he comprovat la variable d'entorn ANDROID_HOME: echo $ANDROID_HOME i retorna: /home/xcarol/workspace/android-sdk he executat /home/xcarol/workspace/android-sdk/platform-tools/adb i apareix l'ajuda del adb.

VS Code: It seems like your adb is correctly installed and the ANDROID_HOME environment variable is set properly. However, Visual Studio Code might not be picking up the environment variable. To resolve this, you can try the following steps:

  1. Add ANDROID_HOME to Visual Studio Code settings: Add the ANDROID_HOME environment variable to your Visual Studio Code settings to ensure it is recognized.
{
  "terminal.integrated.env.linux": {
    "ANDROID_HOME": "/home/xcarol/workspace/android-sdk"
  }
}

Show in Settings Editor

  1. Restart Visual Studio Code: After adding the environment variable to the settings, restart Visual Studio Code to apply the changes.

  2. Verify the environment variable in the terminal: Open a new integrated terminal in Visual Studio Code and verify that the ANDROID_HOME environment variable is set correctly by running:

   echo $ANDROID_HOME
  1. Run flutter doctor again: After verifying the environment variable, run flutter doctor again to check if the issue is resolved:
   flutter doctor

If the issue persists, you might want to check if there are any additional environment variables or paths that need to be set for adb to work correctly.

xcarol: it seems dart daemon is failling. current file are the daemon logs.

GitHub Copilot: Based on the log file, it seems like the Dart tooling daemon is starting correctly. However, there might be an issue with the device detection or configuration. Here are a few steps to troubleshoot the issue:

  1. Ensure adb is in your PATH: Make sure that the adb executable is in your system's PATH. You can add it to your PATH by adding the following line to your .bashrc or .zshrc file:
export PATH=$PATH:/home/xcarol/workspace/android-sdk/platform-tools

Then, reload your shell configuration:

source ~/.bashrc  # or source ~/.zshrc
  1. Verify adb devices: Run the following command to check if your device is recognized by adb:
adb devices

Ensure that your device appears in the list of connected devices.

  1. Restart the Dart and Flutter daemons: Sometimes, restarting the daemons can help resolve issues. You can do this by running:
flutter clean
flutter pub get
  1. Check for additional logs: Look for any additional error messages or logs that might provide more information about the issue.

  2. Update Flutter and Dart SDKs: Ensure that you are using the latest versions of Flutter and Dart SDKs. You can update them by running:

flutter upgrade
  1. Reinstall the Dart and Flutter extensions: Try reinstalling the Dart and Flutter extensions in Visual Studio Code to ensure they are correctly configured.

If the issue persists, please provide more details or additional logs that might help diagnose the problem further.

xcarol: when I run sdb devices it throws this error: 01-09 17:54:00.002 161292 161292 E adb : usb_libusb.cpp:571 failed to open device: Access denied (insufficient permissions) 01-09 17:54:00.002 161292 161292 I adb : transport.cpp:1150 320507a5: connection terminated: failed to open device: Access denied (insufficient permissions)

GitHub Copilot: The error message indicates that adb does not have the necessary permissions to access your device. This is a common issue on Linux systems. You can resolve it by setting up the necessary udev rules for your device. Here are the steps:

  1. Create a udev rules file: Create a new file for the udev rules. You can name it 51-android-usb.rules and place it in the

rules.d

directory.

sudo nano /etc/udev/rules.d/51-android-usb.rules
  1. Add the udev rules: Add the following content to the file. This example includes rules for various manufacturers. You may need to add specific rules for your device's manufacturer.
# Google
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", MODE="0666", GROUP="plugdev"
# Samsung
SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", MODE="0666", GROUP="plugdev"
# HTC
SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"
# Sony Ericsson
SUBSYSTEM=="usb", ATTR{idVendor}=="0fce", MODE="0666", GROUP="plugdev"
# LG
SUBSYSTEM=="usb", ATTR{idVendor}=="1004", MODE="0666", GROUP="plugdev"
# Motorola
SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", MODE="0666", GROUP="plugdev"
# Huawei
SUBSYSTEM=="usb", ATTR{idVendor}=="12d1", MODE="0666", GROUP="plugdev"
# ZTE
SUBSYSTEM=="usb", ATTR{idVendor}=="19d2", MODE="0666", GROUP="plugdev"
# Nvidia
SUBSYSTEM=="usb", ATTR{idVendor}=="0955", MODE="0666", GROUP="plugdev"
# Amazon
SUBSYSTEM=="usb", ATTR{idVendor}=="1949", MODE="0666", GROUP="plugdev"
  1. Reload udev rules: After saving the file, reload the udev rules to apply the changes.
sudo udevadm control --reload-rules
sudo udevadm trigger
  1. Restart the adb server: Restart the adb server to ensure it picks up the new permissions.
adb kill-server
adb start-server
  1. Check connected devices: Finally, check if your device is recognized by adb.
adb devices

This should resolve the permission issue and allow adb to access your device. If the problem persists, ensure that your user is part of the plugdev group:

sudo usermod -aG plugdev $USER

Then, log out and log back in for the group changes to take effect.

xcarol: When I try to debug the app these logs appear in the debug console: adb: failed to install /home/xcarol/workspace/overmaps/build/app/outputs/flutter-apk/app-debug.apk: Failure [INSTALL_FAILED_USER_RESTRICTED: Install canceled by user] Error launching application on 2312DRA50G.

GitHub Copilot: The error INSTALL_FAILED_USER_RESTRICTED: Install canceled by user indicates that the installation of the APK was canceled by the device's user or restricted by the device's settings. Here are a few steps to resolve this issue:

  1. Check Device Settings: Ensure that your device allows installations from unknown sources. This setting is usually found under Settings > Security > Install unknown apps.

  2. Enable Developer Options: Make sure that Developer Options are enabled on your device. Go to Settings > About phone and tap on the Build number seven times to enable Developer Options. Then, go to Settings > Developer options and ensure that USB debugging is enabled.

  3. Revoke USB Debugging Authorizations: Sometimes, revoking USB debugging authorizations and re-authorizing the computer can help. Go to Settings > Developer options and find the Revoke USB debugging authorizations option. After revoking, reconnect your device and authorize the computer again.

  4. Check for Device Management Policies: If your device is managed by an organization (e.g., a work device), there might be policies in place that restrict app installations. Check with your IT department or device administrator.

  5. Restart ADB Server: Restart the ADB server to ensure it is running correctly.

adb kill-server
adb start-server
  1. Reinstall the App: Try uninstalling the existing app from your device and then reinstalling it via the debug process.
adb uninstall com.yourcompany.yourapp

Replace com.yourcompany.yourapp with your app's package name.

  1. Check for Storage Permissions: Ensure that your app has the necessary storage permissions to install the APK. You can grant storage permissions manually if needed.

After performing these steps, try debugging the application again. If the issue persists, please provide more details about your device and any additional error messages you encounter.
