java - 如何在 androidTest 运行时发送模拟位置坐标？

Question

我正在开发一款基于 Here SDK 的导航应用。现在，当我进行集成测试 (androidTest) 时，我需要在 Android 模拟器 (Nexus 10 API 28) 上模拟不同的 GPS 坐标。我尝试了很多不同的方法，但没有任何效果(LocationManager、Fusedlocationproviderclient、ADB shell appops set mock_location 等......唯一有用的是 ADB emu geo fix，但这还不够......)而且我没有在 Android 文档中找到有关位置/坐标测试的任何有用信息。有没有办法在测试运行时以编程方式更改和更新模拟器 GPS 坐标？

这个答案对我有用，张贴在这里供您引用。随时对此进行改进并作为答案发布。我遇到了类似的障碍点，在对 SO 进行研究后得出了这个统一的答案。请参阅底部的引用资料，了解一些与 SO 相关的答案。

它包括您提到的许多尝试，因此如果它仍然对您不起作用，这至少可以帮助您确定其他一些不相关的原因。我在 Nexus 10 API 28 模拟器上运行了这个。

请注意，模拟器必须在运行测试之前运行并且您的应用需要已经安装；否则，gradle 'adb' 命令会失败。 (一区进行改进)。

这有两个部分:1) 更新您的 build.gradle 和 2) 测试位置模拟。

build.gradle (app) 更新

(该任务只应在调试版本中执行 - 因为它是作为依赖项添加到“assembleDebug”的，所以我相信这已经完成。)

// The objective of this task and supporting code is to enable mock locations
// on the target emulator device.
//
// ** REPLACE 'APP PACKAGE NAME' with your app's package name. **

// These tasks should be disabled in some way prior to release.

task enableMockLocationForTestsOnDevice(type: Exec) {
   project.logger.lifecycle("------enableMockLocationForTestsOnDevice------\n")


   if (true) {
       project.logger.lifecycle("------enabled------\n")
       Properties properties = new Properties()
       properties.load(project.rootProject.file('local.properties').newDataInputStream())
       def sdkDir = properties.getProperty('sdk.dir')
       def adb = "$sdkDir/platform-tools/adb"
       description 'enable mock location on connected android device before executing any android test'
       commandLine "$adb", 'shell', 'appops', 'set', 'APP PACKAGE NAME', 'android:mock_location', 'allow'
   }
}

afterEvaluate {
    // Note: the app must be already installed on device in order to this to run!
    connectedDebugAndroidTest.dependsOn enableMockLocationForTestsOnDevice
    connectedAndroidTest.dependsOn enableMockLocationForTestsOnDevice
}

tasks.whenTaskAdded { task ->
    if (task.name == 'assembleDebug') {
        task.dependsOn('enableMockLocationForTestsOnDevice')
    }
}

//...

// This rule should be familiar - it's standard part of espresso test
@Rule
public ActivityTestRule<(your activity)> mActivityRule = new ActivityTestRule<>((your activity class));

// ...

// Utility invocation in test
// start location updates - 25m/s (~55mph)
LatLng startPos = new LatLng(39.0, -77.0);
LocationUtils.startUpdates(mActivityRule.getActivity(),
        new Handler(Looper.getMainLooper()),
        startPos, 340, 25);

// ...    

// (In a test utility class in this example: LocationUtils.java)
// Utility - uses SphericalUtil to maintain a position based on
//           initial starting position, heading and movement value (in
//           meters) applied every 1 second.  (So a movement value
//           of 25 equates to 25m/s which equates to ~55MPH)
public static void startUpdates(
    final Activity activity, final Handler mHandler, final LatLng pos, 
    final double heading, final double movement) {


    mHandler.postDelayed(new Runnable() {
        private LatLng myPos = new LatLng(pos.latitude,pos.longitude);

        @Override
        public void run() {

            Location mockLocation = new Location(LocationManager.GPS_PROVIDER); // a string
            mockLocation.setLatitude(myPos.latitude);  // double
            mockLocation.setLongitude(myPos.longitude);
            mockLocation.setAltitude(100);
            mockLocation.setTime(System.currentTimeMillis());
            mockLocation.setAccuracy(1);
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
                mockLocation.setElapsedRealtimeNanos(SystemClock.elapsedRealtimeNanos());
            }

            LocationServices.getFusedLocationProviderClient(activity).setMockMode(true);
            LocationServices.getFusedLocationProviderClient(activity).setMockLocation(mockLocation);


            // compute next position
            myPos = SphericalUtil.computeOffset(myPos, movement, heading);
            mHandler.postDelayed(this, 1000);
        }
    }, 1000);
}
