Quick Start
For a simple Android app with both Java and Native code, the following config should get you started. See Launch Configuration Options for more details.
{
"version": "0.2.0",
"configurations": [
// Launch app for debugging
{
"name": "Android",
"type": "android-debug",
"request": "launch",
"target": "select",
"mode": "dual", // Change to `java` or `native` to attach only Java or Native debugger.
"packageName": "com.example.sampleapplication", // Package name for your app.
"launchActivity": ".MainActivity", // Activity to launch
"native": {
"symbolSearchPaths": [
"${workspaceFolder}/app/build/intermediates/cmake/debug/obj/${command:abi}/",
],
},
"java": {
"sourcePaths": ["${workspaceFolder}/app/src/main/java"]
}
},
// Attach to running app
{
"name": "Android",
"type": "android-debug",
"request": "attach",
"target": "select",
"pid": "${command:pickAndroidProcess}",
"mode": "dual", // Change to `java` or `native` to attach only Java or Native debugger.
"packageName": "com.example.sampleapplication", // Package name for your app.
"native": {
"symbolSearchPaths": [
"${workspaceFolder}/app/build/intermediates/cmake/debug/obj/${command:abi}/",
],
},
"java": {
"sourcePaths": ["${workspaceFolder}/app/src/main/java"]
}
}
]
}How to use
Create a launch configuration in your launch.json file with type: android-debug to use this extension.
Launch Configuration Options
Here are all the options supported with explanation and example values.
{
// Set the name of the launch config.
"name": "Android",
// Set type to `android-debug` to use this extension.
"type": "android-debug",
// Request.
// `launch` for launching and debugging the app.
// `attach` for attaching to already running app.
"request": "launch" or "attach",
// Target device for debugging.
// This can `select`, `last-selected` or serial of the connected android device as shown in 'adb devices'
"target": "select",
// Process id of the app.
// Set to `${command:pickAndroidProcess}` to pick the process when you start the debugging.
// Required and only applicable for `attach` request.
"pid": "${command:pickAndroidProcess}",
// Full path to the built APK.
// If available this apk will be installed first to the target device.
// At least one of `apkPath` or `packageName` is required for `launch` request.
"apkPath": "${workspaceFolder}/app/build/outputs/apk/debug/app-debug.apk",
// Package name of your app.
// At least one of `apkPath` or `packageName` is required for `launch` request.
"packageName": "com.example.sampleapplication",
// Specify the activity you'd want to launch for debugging
// The activity is launched with the following command:
// $ adb shell am start -D -a android.intent.action.MAIN -c android.intent.category.LAUNCHER ${packageName}/${launchActivity}
// Required and only applicable for `launch` request.
"launchActivity": ".MainActivity",
// Mode for debugging. One of `java`, `native` or `dual`.
// Defaults to `java` if not specified.
"mode": "dual",
// Resume app process after attaching native debugger in case it is waiting for debugger by attaching a dummy Java debugger.
// Defaults to `true` for `launch` request, `false` for `attach` request.
// Only applicable in 'native' mode.
"resumeProcess": true,
// Options for native debugging
"native": {
// List of supported ABIs for the app.
// Defaults to `android-debug.abiSupported` configuration if available.
"abiSupported": ["armeabi-v7a", "arm64-v8a", "x86", "x86_64"],
// Map of ABI to custom string. To be used with ${command:mappedAbi}.
// This can be useful if you have custom build system and the location of SO files uses custom strings for ABIs.
// Defaults to `android-debug.abiMap` configuration if available.
"abiMap": {
"armeabi-v7a": "arm",
"arm64-v8a": "arm64",
"x86": "x86",
"x86_64": "x64",
},
// ABI to use for the current debug session.
// This can be set to one of the ABIs directly, or to `select` to show a picker.
"abi": "select",
// Paths where to look for the SO files used in your app.
// You can use `${command:abi}` and `{command:mappedAbi}` when specifying the paths.
"symbolSearchPaths": [
"${workspaceFolder}/app/build/intermediates/cmake/debug/obj/${command:abi}/",
],
// All other options specified here are passes as is to the underlying Native debugger. See https://github.com/vadimcn/vscode-lldb/blob/master/MANUAL.md
},
// Options for java debugging
"java": {
// List of source paths for your java files.
"sourcePaths": ["${workspaceFolder}/app/src/main/java"]
// All other options specified here are passes as is to the underlying Java debugger. See https://marketplace.visualstudio.com/items?itemName=vscjava.vscode-java-debug
