Question

我知道有关在Android has been discussed many times上以编程方式打开/关闭GPS的问题，答案总是一样的：

“出于安全/隐私原因，您不能转发到位置偏好设置屏幕并让用户启用/禁用它。”

据我所知，不过我最近从市场上购买了Tasker，并且您可以通过它完成许多其他事情，您可以设置规则，以便在输入预先确定的应用程序时自动启用GPS并禁用它在退出时（请参阅here获取有关如何操作的教程，它只是有效！）并且此应用程序无法使用固件签名密钥签名，因为它适用于许多Android版本和不同的设备而且您不需要甚至需要扎根。

我想在我的应用中执行此操作。当然，我不想破坏用户隐私，因此我首先会询问用户是否要使用典型的“记住我的决定”复选框自动打开它，如果他回答是，请启用它。

有没有人对Tasker如何实现这一点有任何想法或线索？

Answer 1

可以通过exploiting电源管理器小部件中的错误切换GPS。请参阅此xda thread进行讨论。

这是我使用的一些示例代码

private void turnGPSOn(){
    String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

    if(!provider.contains("gps")){ //if gps is disabled
        final Intent poke = new Intent();
        poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider"); 
        poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
        poke.setData(Uri.parse("3")); 
        sendBroadcast(poke);
    }
}

private void turnGPSOff(){
    String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

    if(provider.contains("gps")){ //if gps is enabled
        final Intent poke = new Intent();
        poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
        poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
        poke.setData(Uri.parse("3")); 
        sendBroadcast(poke);
    }
}

使用以下内容测试电源控件小部件的现有版本是否允许您切换gps。

private boolean canToggleGPS() {
    PackageManager pacman = getPackageManager();
    PackageInfo pacInfo = null;

    try {
        pacInfo = pacman.getPackageInfo("com.android.settings", PackageManager.GET_RECEIVERS);
    } catch (NameNotFoundException e) {
        return false; //package not found
    }

    if(pacInfo != null){
        for(ActivityInfo actInfo : pacInfo.receivers){
            //test if recevier is exported. if so, we can toggle GPS.
            if(actInfo.name.equals("com.android.settings.widget.SettingsAppWidgetProvider") && actInfo.exported){
                return true;
            }
        }
    }

    return false; //default
}

现在不允许所有这些答案。这是正确的：

对于那些仍在寻找答案的人：

以下是OLA Cabs和其他类似应用程序的用法。

在你的onCreate

中添加它

if (googleApiClient == null) {
    googleApiClient = new GoogleApiClient.Builder(this)
            .addApi(LocationServices.API).addConnectionCallbacks(this)
            .addOnConnectionFailedListener(Login.this).build();
    googleApiClient.connect();
            LocationRequest locationRequest = LocationRequest.create();
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    locationRequest.setInterval(30 * 1000);
    locationRequest.setFastestInterval(5 * 1000);
    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(locationRequest);

    // **************************
    builder.setAlwaysShow(true); // this is the key ingredient
    // **************************

    PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi
            .checkLocationSettings(googleApiClient, builder.build());
    result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
        @Override
        public void onResult(LocationSettingsResult result) {
            final Status status = result.getStatus();
            final LocationSettingsStates state = result
                    .getLocationSettingsStates();
            switch (status.getStatusCode()) {
            case LocationSettingsStatusCodes.SUCCESS:
                // All location settings are satisfied. The client can
                // initialize location
                // requests here.
                break;
            case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                // Location settings are not satisfied. But could be
                // fixed by showing the user
                // a dialog.
                try {
                    // Show the dialog by calling
                    // startResolutionForResult(),
                    // and check the result in onActivityResult().
                    status.startResolutionForResult(Login.this, 1000);
                } catch (IntentSender.SendIntentException e) {
                    // Ignore the error.
                }
                break;
            case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                // Location settings are not satisfied. However, we have
                // no way to fix the
                // settings so we won't show the dialog.
                break;
            }
        }
    });
}

这些是实施方法：

@Override
public void onConnected(Bundle arg0) {
    // TODO Auto-generated method stub

}

@Override
public void onConnectionSuspended(int arg0) {
    // TODO Auto-generated method stub

}

@Override
public void onConnectionFailed(ConnectionResult arg0) {
    // TODO Auto-generated method stub

}

启用GPS：

Intent intent=new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", true);
sendBroadcast(intent);

禁用GPS：

Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", false);
sendBroadcast(intent);

要以编程方式打开或关闭GPS，您需要“root”访问并安装BusyBox。即使有这些，这项任务也并非无足轻重。

此处的示例：Google Drive，Github，Sourceforge

使用2.3.5和4.1.2机器人进行测试。

Answer 9

此代码适用于ROOTED手机：

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        String[] cmds = {"cd /system/bin" ,"settings put secure location_providers_allowed +gps"};
        try {
            Process p = Runtime.getRuntime().exec("su");
            DataOutputStream os = new DataOutputStream(p.getOutputStream());
            for (String tmpCmd : cmds) {
                os.writeBytes(tmpCmd + "\n");
            }
            os.writeBytes("exit\n");
            os.flush();
        }
        catch (IOException e){
            e.printStackTrace();
        }
    }
}

要关闭GPS，您可以使用此命令

settings put secure location_providers_allowed -gps

您还可以使用以下命令切换网络准确度：打开使用：

settings put secure location_providers_allowed +network

关闭你可以使用：

settings put secure location_providers_allowed -network

Answer 10

可能在课堂android.server.LocationManagerService周围使用反思技巧。

此外，还有一种方法（自API 8起）android.provider.Settings.Secure.setLocationProviderEnabled

Answer 11

在另一个问题中提出了答案，但它已经关闭了，我希望社区也能尝试一下。

boolean gpsStatus = locmanager.isProviderEnabled(LocationManager.GPS_PROVIDER);
if (!gpsStatus) {
    Settings.Secure.putString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED, "network,gps");
}

请参阅this comment

此解决方案需要WRITE_SETTINGS和WRITE_SECURE_SETTINGS权限。

Answer 12

自此问题发布后情况发生了变化，现在使用新的Google Services API，您可以提示用户启用GPS：

https://developers.google.com/places/android-api/current-place

您需要在清单中请求ACCESS_FINE_LOCATION权限：

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

在这个问题（https://stackoverflow.com/a/42556648/11211963）中，答案比Rj0078的答案更简单，但也可以解决这个问题。

它显示这样的对话框：

（写在科特林）

    googleApiClient = GoogleApiClient.Builder(context!!)
        .addApi(LocationServices.API).build()
    googleApiClient!!.connect()
    locationRequest = LocationRequest.create()
    locationRequest!!.priority = LocationRequest.PRIORITY_HIGH_ACCURACY
    locationRequest!!.interval = 30 * 1000.toLong()
    locationRequest!!.fastestInterval = 5 * 1000.toLong()

    val builder = LocationSettingsRequest.Builder()
        .addLocationRequest(locationRequest!!)
    builder.setAlwaysShow(true)

    result =
       LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build())
    result!!.setResultCallback { result ->
        val status: Status = result.status
        when (status.statusCode) {
            LocationSettingsStatusCodes.SUCCESS -> {
               // Do something
            }
            LocationSettingsStatusCodes.RESOLUTION_REQUIRED ->
                try {
                    startResolutionForResult(),
                    status.startResolutionForResult(
                        activity,
                        REQUEST_LOCATION
                    )
                } catch (e: SendIntentException) {
                }
            LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE -> {
                // Do something
            }
        }
    }

Answer 14

您只需要从LocationListener删除LocationManager

manager.removeUpdates(listener);

Answer 15

使用此代码简便易行：

权限：

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

遵循此代码以编程方式访问GPS：

LocationManager locationManager ;
 boolean GpsStatus ;


            GPSStatus();

            if(GpsStatus == true)
            {
                textview.setText("Your Location Services Is Enabled");
            }else
                {textview.setText("Your Location Services Is Disabled");}

            Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
            startActivity(intent);


    public void GPSStatus(){
    locationManager = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
    GpsStatus = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
}

Answer 16

正确答案很旧，需要新内容，所以这里是答案

与上次更新一样，我们具有androidx支持，因此请首先在应用程序级别的build.gradle文件中包含依赖项

implementation 'com.google.android.gms:play-services-location:17.0.0'

然后添加您的清单文件：

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

如果您要发布这些内容，请不要忘记征得用户同意

现在这里是代码，只需使用它

 protected void createLocationRequest() {
    LocationRequest locationRequest = LocationRequest.create();
    locationRequest.setInterval(10000);
    locationRequest.setFastestInterval(5000);
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(locationRequest);

    SettingsClient client = LocationServices.getSettingsClient(this);
    Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());



    task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
        @Override
        public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
            // All location settings are satisfied. The client can initialize
            // location requests here.
            // ...

            Toast.makeText(MainActivity.this, "Gps already open", 
                                          Toast.LENGTH_LONG).show();
            Log.d("location settings",locationSettingsResponse.toString());
        }
    });

    task.addOnFailureListener(this, new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            if (e instanceof ResolvableApiException) {
                // Location settings are not satisfied, but this can be fixed
                // by showing the user a dialog.
                try {
                    // Show the dialog by calling startResolutionForResult(),
                    // and check the result in onActivityResult().
                    ResolvableApiException resolvable = (ResolvableApiException) e;
                    resolvable.startResolutionForResult(MainActivity.this,
                            REQUEST_CHECK_SETTINGS);
                } catch (IntentSender.SendIntentException sendEx) {
                    // Ignore the error.
                }
            }
        }
    });
}


@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if(requestCode==REQUEST_CHECK_SETTINGS){

        if(resultCode==RESULT_OK){

            Toast.makeText(this, "Gps opened", Toast.LENGTH_SHORT).show();
            //if user allows to open gps
            Log.d("result ok",data.toString());

        }else if(resultCode==RESULT_CANCELED){

            Toast.makeText(this, "refused to open gps", 
                                         Toast.LENGTH_SHORT).show();
            // in case user back press or refuses to open gps
            Log.d("result cancelled",data.toString());
        }
    }
}

对于所有Android版本（可能是新版本）来说，这都是更易于理解的代码

void checkGPS() {
    LocationRequest locationRequest = LocationRequest.create();

    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);

    SettingsClient settingsClient = LocationServices.getSettingsClient(this);
    Task<LocationSettingsResponse> task = settingsClient.checkLocationSettings(builder.build());

    task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
        @Override
        public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
            Log.d("GPS_main", "OnSuccess");
            // GPS is ON
        }
    });

    task.addOnFailureListener(this, new OnFailureListener() {
        @Override
        public void onFailure(@NonNull final Exception e) {
            Log.d("GPS_main", "GPS off");
            // GPS off
            if (e instanceof ResolvableApiException) {
                ResolvableApiException resolvable = (ResolvableApiException) e;
                try {
                    resolvable.startResolutionForResult(ActivityMain.this, REQUESTCODE_TURNON_GPS);
                } catch (IntentSender.SendIntentException e1) {
                    e1.printStackTrace();
                }
            }
        }
    });
}

您可以在此处处理GPS状态更改

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if(requestCode == Static_AppVariables.REQUESTCODE_TURNON_GPS) {
        switch (resultCode) {
            case Activity.RESULT_OK:
                // GPS was turned on;
                break;
            case Activity.RESULT_CANCELED:
                // User rejected turning on the GPS
                break;
            default:
                break;
        }
    }
}

使用来自 https://developer.android.com/training/location/change-location-settings.html 的最新 API 的简短而简单的解决方案。

您将获得带有 ok 按钮的精美 Google AlertDialog，而无需进行任何设置。

直奔主题。我在片段中的代码：

override fun onResume() {
        super.onResume()
        checkGPSEnabled()
    }

private fun checkGPSEnabled() {
        val manager = requireContext().getSystemService(Context.LOCATION_SERVICE) as LocationManager
        if (manager.isProviderEnabled(LocationManager.GPS_PROVIDER).not()) {
            turnOnGPS()
        }
    }

private fun turnOnGPS() {
        val request = LocationRequest.create().apply {
            interval = 2000
            priority = LocationRequest.PRIORITY_HIGH_ACCURACY
        }
        val builder = LocationSettingsRequest.Builder().addLocationRequest(request)
        val client: SettingsClient = LocationServices.getSettingsClient(requireActivity())
        val task: Task<LocationSettingsResponse> = client.checkLocationSettings(builder.build())
        task.addOnFailureListener {
            if (it is ResolvableApiException) {
                try {
                    it.startResolutionForResult(requireActivity(), 12345)
                } catch (sendEx: IntentSender.SendIntentException) {
                }
            }
        }.addOnSuccessListener {
            //here GPS is On
        }
    }

就是这样。只需复制和粘贴。您还需要： implementation 'com.google.android.gms:play-services-location:18.0.0' 和清单 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
