How to retrieve path to ADB in build.gradle

Question

I trying to start application via gradle task.

task runDebug(dependsOn: [\'installDebug\', \'run\']) {
}

task run(type: Exec) {
comm         


        

Answer 1

The problem was solved.
The variable must contain

def adb = "$System.env.ANDROID_HOME/platform-tools/adb"

And complete task looks like

task run(type: Exec) {
    def adb = "$System.env.ANDROID_HOME/platform-tools/adb"
    commandLine "$adb", 'shell', 'am', 'start', '-n', 'com.example.myexample/.ui.SplashScreenActivity'
}

UPD
Another way without using ANDROID_HOME

task run(type: Exec) {
    def rootDir = project.rootDir
    def localProperties = new File(rootDir, "local.properties")
    if (localProperties.exists()) {
        Properties properties = new Properties()
        localProperties.withInputStream { 
            instr -> properties.load(instr)
        }
        def sdkDir = properties.getProperty('sdk.dir')
        def adb = "$sdkDir/platform-tools/adb"
        commandLine "$adb", 'shell', 'am', 'start', '-n', 'com.example.myexample/.ui.SplashScreenActivity'
    }
}

In Windows you can just register an application path for adb.exe with the following .reg file:

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\adb.exe]
@="D:\\android\\android-studio\\sdk\\platform-tools\\adb.exe"
"Path"="D:\\android\\android-studio\\sdk\\platform-tools"

and just keep your original commandline

Answer 3

we can get if from android extension.

android.adbExe

Answer 4

def androidPlugin = project.plugins.findPlugin("android")
def adb = androidPlugin.sdkHandler.sdkInfo?.adb

Answer 5

My default solution for this issue is to add adb to your path variable so you can use the adb command from every path.
You can set it e.g. from the console like this:

set path=%path%;x:\path\to\adb

Alternative you can set it via the UI. See also this explanation on java.com.

Answer 6

You should use the logic that the Android Gradle plugin already has for finding the SDK and adb locations to ensure your script is using the same ones.

# Android Gradle >= 1.1.0
File sdk = android.getSdkDirectory()
File adb = android.getAdbExe()

# Android Gradle < 1.1.0
File sdk = android.plugin.getSdkFolder()
File adb = android.plugin.extension.getAdbExe()
