业无高卑志当坚，男儿有求安得闲？这篇文章主要讲述如何在Android上以编程方式启用或禁用GPS？相关的知识，希望能为你提供帮助。
我知道关于在an??droid qazxsw poi qazxsw poi has been discussed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，你不能转发到位置首选项屏幕，让用户启用/禁用它。”我明白，不过我最近从市场上购买了many，而且你可以用它完成许多其他事情，你可以设置规则，在输入预先确定的应用程序时自动启用GPS并在退出时禁用它（请参阅times如何做的教程，它只是工作！）和这个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，你甚至不需要扎根。
我想在我的应用程序中执行此操作。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”复选框自动启用它，如果他回答是，则启用它。
有没有人对Tasker如何实现这一点有任何想法或线索？
答案可以通过Tasker切换GPS电源管理器小部件中的错误。看到这个here进行讨论。
这是我使用的一些示例代码

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。

另一答案这是
WRITE_SECURE_SETTINGS提供的最佳解决方案。在初始化android.server.LocationManagerService之后，只需在onCreate的onResume中调用此方法。android.provider.Settings.Secure.setLocationProviderEnabled注意：如果
Google Developers未打开，则此行代码会自动打开对话框。这条线也用于谷歌地图GoogleApiClient另一答案此代码适用于ROOTED手机：
private void updateMarkers() {
if (mMap == null) {
return;
}if (mLocationPermissionGranted) {
// Get the businesses and other points of interest located
// nearest to the device's current location.
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API).build();
mGoogleApiClient.connect();
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(10000);
locationRequest.setFastestInterval(10000 / 2);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);
builder.setAlwaysShow(true);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest
.Builder()
.addLocationRequest(mLocationRequest);
PendingResult<
LocationSettingsResult>
resultPendingResult = LocationServices
.SettingsApi
.checkLocationSettings(mGoogleApiClient, builder.build());
resultPendingResult.setResultCallback(new ResultCallback<
LocationSettingsResult>
() {
@Override
public void onResult(@NonNull LocationSettingsResult locationSettingsResult) {
final Status status = locationSettingsResult.getStatus();
final LocationSettingsStates locationSettingsStates = locationSettingsResult.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 this can be fixed
// by showing the user a dialog.try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(
MainActivity.this,
PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);
} 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;
}}
});
@SuppressWarnings("MissingPermission")
PendingResult<
PlaceLikelihoodBuffer>
result = Places.PlaceDetectionApi
.getCurrentPlace(mGoogleApiClient, null);
result.setResultCallback(new ResultCallback<
PlaceLikelihoodBuffer>
() {
@Override
public void onResult(@NonNull PlaceLikelihoodBuffer likelyPlaces) {
for (PlaceLikelihood placeLikelihood : likelyPlaces) {
// Add a marker for each place near the device's current location, with an
// info window showing place information.
String attributions = (String) placeLikelihood.getPlace().getAttributions();
String snippet = (String) placeLikelihood.getPlace().getAddress();
if (attributions != null) {
snippet = snippet + "
" + attributions;
}mMap.addMarker(new MarkerOptions()
.position(placeLikelihood.getPlace().getLatLng())
.title((String) placeLikelihood.getPlace().getName())
.snippet(snippet));
}
// Release the place likelihood buffer.
likelyPlaces.release();
}
});
} else {
mMap.addMarker(new MarkerOptions()
.position(mDefaultLocation)
.title(getString(R.string.default_info_title))
.snippet(getString(R.string.default_info_snippet)));
}
}
要关闭GPS，您可以使用此命令
Location您还可以使用以下命令切换网络准确度：打开使用：
status.startResolutionForResult(
MainActivity.this,
PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);
关闭你可以使用：
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 + "
");
}
os.writeBytes("exit
");
os.flush();
}
catch (IOException e){
e.printStackTrace();
}
}
}
另一答案自问题发布以来，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：
settings put secure location_providers_allowed -gps
您需要在清单中请求ACCESS_FINE_LOCATION权限：
settings put secure location_providers_allowed +network
另请观看此视频：
settings put secure location_providers_allowed -network
另一答案你只需要从https://developers.google.com/places/android-api/current-place中删除
<
uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
