1、 Gradle 任务列表
2、构建调式APK
一、Gradle 任务
您可以使用 Gradle 包装器命令行工具执行您的 Android 项目中可用的所有构建任务。它可作为 Windows 的批处理文件 (gradlew.bat) 和 Linux 与 Mac 的 shell 脚本文件 (gradlew.sh) 使用，可以从您使用 Android Studio 创建的每个项目的根获取。
要使用包装器运行任务，请使用下列命令之一：
- 在 Windows 上：
gradlew task-name
- 在 Mac 或 Linux 上：
./gradlew task-name
要查看您的项目所有可用构建任务的列表，请执行 tasks：
gradlew tasks

projects - Displays the sub-projects of root project 'UsingDemosSample'.
properties - Displays the properties of root project 'UsingDemosSample'.
tasks - Displays the tasks runnable from root project 'UsingDemosSample' (some of the displayed tasks may belong to subprojects).
Install tasks
-------------
installDebug - Installs the Debug build.
installDebugAndroidTest - Installs the android (on device) tests for the Debug build.
uninstallAll - Uninstall all applications.
uninstallDebug - Uninstalls the Debug build.
uninstallDebugAndroidTest - Uninstalls the android (on device) tests for the Debug build.

connectedCheck - Runs all device checks on currently connected devices.
connectedDebugAndroidTest - Installs and runs the tests for debug on connected devices.
deviceAndroidTest - Installs and runs instrumentation tests using all Device Providers.
deviceCheck - Runs all device checks using Device Providers and Test Servers.
lint - Runs lint on all variants.
lintDebug - Runs lint on the Debug build.
lintRelease - Runs lint on the Release build.
test - Run unit tests for all variants.
testDebugUnitTest - Run unit tests for the debug build.
testReleaseUnitTest - Run unit tests for the release build.
二、构建调试 APK
要想立即测试和调试应用，您可以构建调试 APK。调试 APK 通过 SDK 工具提供的调试密钥签署，并允许通过 adb 调试。
要构建调试 APK，请打开命令行，然后导航至项目目录的根 - 在 Android Studio 中，选择 View > Tool Windows > Terminal。要启动调试构建，请调用 assembleDebug 任务：
gradlew assembleDebug
这将在 project_name/module_name/build/outputs/apk/ 中创建一个名称为 module_name-debug.apk 的 APK。此文件已通过调试密钥签署，并与 zipalign 对齐，因此，您可以在设备上立即安装。
或者要构建 APK，并立即在运行的模拟器或连接的设备上安装，请改为调用 installDebug：
gradlew installDebug
上述任务名称中的“调试”部分仅仅是构建变体名称的骆驼拼写法版本，因此，可以使用您想要汇编或安装的任何构建变体替换。例如，如果您有“演示”产品风味，则可以过 assembleDemoDebug 任务构建调试版本。
要查看每个变体可用的所有构建和安装任务（包括卸载任务），请运行 tasks 任务。
