SettingsClient.checkSettings 始终失败，状态为 LocationSettingsStatusCodes.RESOLUTION_REQUIRED

Question

我正在我的应用程序中使用LocationServices。在使用位置服务之前，我尝试验证具有所需设置的位置是否已打开，但我面临的问题SettingsClient.checkSettings始终是failing。请参阅我LocationRequest和LocationSettingRequest建造者：

位置请求

 mLocationRequest = LocationRequest()
        mLocationRequest.interval = interval
        mLocationRequest.fastestInterval = interval

        Log.v(TAG, "distance => $distance")
        if(distance > 0) {
            mLocationRequest.smallestDisplacement = distance
        }

        mLocationRequest.priority = LocationRequest.PRIORITY_HIGH_ACCURACY

        buildLocationSettingsRequest()

位置设置RequestBuilder

private fun buildLocationSettingsRequest() {
        val builder = LocationSettingsRequest.Builder()
        builder.addLocationRequest(mLocationRequest)
        mLocationSettingsRequest = builder.build()

        mSettingsClientInit = true
    }

我checkSettings要求

mSettingsClient.checkLocationSettings(mLocationSettingsRequest)
                .addOnSuccessListener(this, object : OnSuccessListener<LocationSettingsResponse> {

                    override fun onSuccess(locationSettingsResponse: LocationSettingsResponse) {
                        Log.i(TAG, "LocationManager: All location settings are satisfied.");
                        mLocationCallback?.let {
                            fusedLocationClient?.requestLocationUpdates(mLocationRequest, mLocationCallback, Looper.myLooper());
                        }
//                        updateUI();
                    }
                })
                .addOnFailureListener(this, object : OnFailureListener {
                    override fun onFailure(e: Exception) {
                        Log.v(TAG, "Request PErmission failure");
                        var statusCode = (e as ApiException).getStatusCode()
                        when (statusCode) {
                            LocationSettingsStatusCodes.RESOLUTION_REQUIRED -> {
                                try {
                                    // Show the dialog by calling startResolutionForResult(), and check the
                                    // result in onActivityResult().
                                    var rae = e as ResolvableApiException;
                                    rae.startResolutionForResult(this@BaseLocationActivity, REQUEST_CHECK_SETTINGS);
                                } catch (sie: IntentSender.SendIntentException) {
                                    Log.v(TAG, "PendingIntent unable to execute request.");
                                }
                            }
                            LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE -> {
                                mRequestingLocationUpdates = false;
                                Log.v(TAG, "Settings change unavailable.");
                            }

                        }
                    }
                }
                )

它始终是onFailure的结果addOnFailureListener。谁能帮我看看这可能是什么问题吗？此设置对话框显示“确定”以启用设置，我按“确定”，再次出现相同的对话框并带有 onFailure 回调。

它发生在某些设备上，而不是所有设备上。

您好，按照此代码解决您的问题，我添加了 GPSUtils 类，借助该类您可以轻松管理 GPS。

\n\n

对于 SettingsClient\xe2\x80\x99s 失败回调，将显示 GPS 对话框，并将导致 Activity\xe2\x80\x99s onActivityResult()。所以基本上如果用户同意打开 GPS，我们就可以在我们的活动中启用 GPS 标志。

\n\n

@Override\nprotected void onActivityResult(int requestCode, int resultCode, Intent data) {\n    super.onActivityResult(requestCode, resultCode, data);\n    if (resultCode == Activity.RESULT_OK) {\n        if (requestCode == AppConstants.GPS_REQUEST) {\n            isGPS = true; // flag maintain before get location\n        }\n    }\n}\n

\n\n

现在在获取位置之前调用 GpsUtils 类。

\n\n

new GpsUtils(this).turnGPSOn(new GpsUtils.onGpsListener() {\n    @Override\n    public void gpsStatus(boolean isGPSEnable) {\n        // turn on GPS\n        isGPS = isGPSEnable;\n    }\n});\n
