在FusedLocationProviderApi中设置模拟位置

Question

我正在尝试从FusedLocationProviderApi获取模拟更新，但我似乎无法使其工作。这是我在android工具测试中的设置方法：

locationProvider = new LocationProvider(InstrumentationRegistry.getTargetContext().getApplicationContext(), settings);

// Connect first, so that we don't receive 'true' location
locationProvider.googleApiClient.blockingConnect();
// Set mock mode, to receive only mock locations
LocationServices.FusedLocationApi.setMockMode(locationProvider.googleApiClient, true);

InstrumentationRegistry.getInstrumentation().runOnMainSync(new Runnable() {
    @Override
    public void run() {
        // Start receiving locations; this call will connect api client, and if it's already connected (or after it connects) it will register for location updates
        locationProvider.start();
    }
});
// wait until we can request location updates
while (!locationProvider.isReceivingLocationUpdates) {
    Thread.sleep(10);
}

在这之后，我期望任何对LocationServices.fusedLocationApi.setMockLocation(apiClient, location)的调用都会设置我的侦听器将接收到的模拟位置。不幸的是，事实并非如此，听众保持沉默。

我设置模拟位置的简单方法(或者我是这么认为的)如下所示：

private void setMockLocation(final Location location) throws Exception {
    assertTrue(locationProvider.googleApiClient.isConnected());
    assertTrue(locationProvider.isReceivingLocationUpdates);

    final CountDownLatch countDownLatch = new CountDownLatch(1);
    LocationServices.FusedLocationApi.setMockMode(locationProvider.googleApiClient, true)
            .setResultCallback(new ResultCallback<Status>() {
                @Override
                public void onResult(Status status) {
                    assertTrue(status.isSuccess());
                    LocationServices.FusedLocationApi.setMockLocation(locationProvider.googleApiClient, location)
                            .setResultCallback(new ResultCallback<Status>() {
                                @Override
                                public void onResult(Status status) {
                                    assertTrue(status.isSuccess());
                                    countDownLatch.countDown();
                                }
                            });
                }
            });
    assertTrue(countDownLatch.await(500, TimeUnit.MILLISECONDS));
}

方法成功返回，但侦听器未收到任何位置。我真的不知所措。最糟糕的部分是测试有时会通过，但非常随机(在这种情况下，执行多次的相同代码将在随后的调用中通过并失败)。为了完整起见，我的调试清单具有以下权限：

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />

我已经允许在设置中使用模拟位置。

这是一个更新的kotlin版本。请注意，您需要在开发选项中选择应用程序作为模拟位置提供程序，并在调试清单文件中设置执行此操作的权限。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android">
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"
    tools:ignore="ProtectedPermissions" />
</manifest>

在onCreate中，活动将有一个带有初始值设定项的val

  private lateinit var fusedLocationClient: FusedLocationProviderClient

在oncreate()中

  fusedLocationClient = LocationServices.getFusedLocationProviderClient(this)


  fusedLocationClient.setMockMode(BuildConfig.DEBUG)

  fusedLocationClient.lastLocation
        .addOnSuccessListener { location : android.location.Location? ->
            // Got last known location. In some rare situations this can be null.
            Toast.makeText(this, location.toString(), Toast.LENGTH_SHORT).show()

        }
        .addOnFailureListener {  Toast.makeText(this, "failed", Toast.LENGTH_SHORT).show() }

最后还有一种模拟位置的方法

 private fun setMockLocation(location: android.location.Location) {
    fusedLocationClient.setMockLocation(location)
        .addOnSuccessListener { Log.d(TAG, "location mocked") }
        .addOnFailureListener { Log.d(TAG, "mock failed") }
}
