Cannot find location android

How to Fix “SDK location not found” in Android Studio?

Google developed Android SDK which is a Software Development Kit developed by Google for the Android platform. You can create Android apps using Android SDK, and you don’t need to be an expert to use it. Android SDK and Android Studio come bundled together, with Google’s official integrated development environment (IDE) for the Android operating system.

In this article, we see how to fix an error that is related to the main Android building component of Android Studio that is the Android SDK. The most common error related to Android SDK is “SDK location not found“. This message pops up stating that the location of Android SDK was not detected when the path of SDK is assigned incorrectly. There can also be other reasons for this error message as well and we will see ways to get rid of this error.

When switching from one IDE to another (Like from Eclipse to Android Studio)

Method 1

In this case, follow the below steps:

Method 2

In case the above procedure doesn’t work then add the ANDROID_HOME variable in “Environment Variables” as C:\Users\Username\AppData\Local\Android\Sdk.

Method 3

In case it does not work even then, then you need to change the directory path on Project Structure as well.

• Close the current project and you’ll see a pop-up with a dialog which will then proceed to Configure option.
• Configure -> Project Defaults -> Project Structure -> SDKs on left column -> Android SDK Home Path -> give the exact path as you did on local.properties and select Valid Target.

Method 4

A settings.gradle file might be missing from the project. Make sure that the file exists from the project you are importing. If not add the settings.gradle file with the following:

Save the file and put it in the top-level folder in your project.

Простой способ добавить геолокацию в свой проект для Android

Долго я прочёсывал интернет в поисках простого решения, как мне в проект добавить 1 только класс и больше не беспокоиться о проблемах геолокации.
Критерии были такие:
1) решить всё в 1 классе, как можно меньше используя внешний код.
2) у пользователя должна быть всегда под рукой 1 static переменная в которой указанно его местоположение и больше ни о чём он знать не должен.

Большинство постов не отвечало на поставленный вопрос: конечно сначала нужно обратиться к сервису, потом нужно установить listner, потом вы можете посмотреть на трёхстраничный краткий пример как это делать.
В итоге я написал свой класс, с которым и хочу вас познакомить: он прост в использовании и с ним сможет справиться любой: просто добавьте его в проект и будет вам счастье.

Итак, что же здесь есть?

Класс разделен на 3 части:
1) imHere — переменная типа Location, в которой будет всегда доступна самая последняя информация о местоположении пользователя.
2) функция SetUpLocationListener — в любом случае нам нужна будет начальная установка для того, чтобы система начала сама без нашего участия выполнять обновление переменной imHere.
3) все остальные обязательные части LocationListener, которые можно переделать по собственному желанию.

Итак, как это работает?

1) создаем класс MyLocationListener
2) копируем в него код написанный выше
3) в основной функции (например MainActivity) ближе к началу запускаем:

или для любителей потоков

4) теперь у нас всегда и в любой части нашего проекта есть переменная MyLocationListener.imHere типа Location, в которой хранится самое последнее местоположение пользователя и множество дополнительной информации, как например скорость или точность определения местоположения.

И в заключение: это принципиальный код и тут есть что улучшать. Например нужно учитывать, что первое время локация может быть не определена и imHere будет null, но это всё не скоро: сейчас у нас есть класс, который позволяет нам без лишних усилий и с минимумом знаний добавить геолокацию в свой проект.

(!) Не забудьте: в зависимости от выбранного провайдера нужно добавить в манифест соответствующее разрешение. Например используемый выше GPS_PROVIDER требует добавления следующей строчки в манифест:

error: package com.google.android.gms.location does not exist #3282

Comments

dpyeates commented Feb 10, 2020

Using the latest package from github, and after following all install instructions (having previous versions working perfectly), I get an error: package com.google.android.gms.location does not exist.

Build fails on line 17 of AirMapManager.java.

This was added in the recent commit «Improved user location on Android (#2993)»

Here is an extract from my app/build.gradle

Library version: next

The text was updated successfully, but these errors were encountered:

dpyeates commented Feb 10, 2020

To the android-react-native-maps.gradle file removes the no definitions for me, but then introduces new errors around setUserLocationPriority, setUserLocationUpdateInterval and setUserLocationFastestInterval not being defined in AirMapManager.java

akiladevinda commented Feb 12, 2020

Any solutions regarding this ? @dpyeates

akiladevinda commented Feb 12, 2020

FIX

I fix this solution by removing bellow existing maps package from my node_modules folder

and re-install it with this command yarn add react-native-maps -E or npm install react-native-maps —save-exact

danial031193 commented Feb 13, 2020

akiladevinda commented Feb 14, 2020

@danial031193 Can you post your updated package.json ?

danial031193 commented Feb 14, 2020 •

In MacOS build success. In Ubuntu failed:

akiladevinda commented Feb 14, 2020

@danial031193 uninstall your existing react-native-maps from package.json and try npm install react-native-maps —save-exact or using yarn add react-native-maps -E

@danial031193 uninstall your existing react-native-maps from package.json and try npm install react-native-maps —save-exact or using yarn add react-native-maps -E

It didn’t work for me :/

jorgeluis91x commented Feb 27, 2020

I needed fix that quicky so I added
implementation ‘com.google.android.gms:play-services-location:16.+’ in the react-native-library
on this file node_modules/react-native-maps/lib/android/build.gradle and I fix one of the bug and for the another one Comment from line 165 to line 175 in this path
node_modules/react-native-maps/lib/android/src/main/java/com/airbnb/android/react/maps/AirMapManager.java

something like that
`@ReactProp(name = «userLocationPriority»)
public void setUserLocationPriority(AirMapView view, @nullable String accuracy) <
view.setUserLocationPriority(MY_LOCATION_PRIORITY.get(accuracy));
>

@ReactProp(name = «userLocationUpdateInterval», defaultInt = 5000)
public void setUserLocationUpdateInterval(AirMapView view, int updateInterval) <
view.setUserLocationUpdateInterval(updateInterval);
>

@ReactProp(name = «userLocationFastestInterval», defaultInt = 5000)
public void setUserLocationFastestInterval(AirMapView view, int fastestInterval) <
view.setUserLocationFastestInterval(fastestInterval);
>`

I know there are 3 properties that are not working but I needed fix it for my project

Find My Android without Device Manager

Phone Number

Current GPS Location

Track Current Android Location Without Pre-Configuring

Nowadays mobile devices are an essential part of modern life. We talk, actively use social medias, browse Internet, play games, interact with bunch of Android apps and services. Some of us use these devices for work-related purposes (Google account and applications make it a far more pleasant experience). Smartphones and tablets make our lives easier. But just imagine that one day you may unexpectedly lose it. Hopefully, you have enabled PIN code or graphical password protection on your Android phone or tablet, which means you are virtually safe from data leaks and only need to figure out how to get your lost or stolen device back. For such cases, Google developers created “Find My Android” feature activated via “Device Manager” app. The greatest challenge lies in the fact that a number of conditions must be met to launch this mode.

Find My Device Mode

“Lost Devise Mode” activation is a perfect method for searching a lost device. However, in real life, many users ignore recommendations regarding creating a “Device Manager” account. Moreover, one must remember an email specified at sign-up and a password to launch this “Lost Devise Mode”. It may take a lot of precious time to recover this data.

Disabled Geolocation

By disabling location services, you can save battery charge or even preserve your own privacy. Many inexperienced users take this step. However, in case of losing a device, these actions will be a serious obstacle in searching for it. Disabled Geolocation makes it impossible to activate “Find My Android” feature via “Device Manager”.

Internet Connection

Android Device can be disabled even when a screen lock via a passcode is used. “Find My Android” can’t be used on a switched off device, since mobile data will not be transmitted to a network.

Android Firmware

Any major service center can “reflash” Android for restoring factory settings and even assigning IMEI from some other identical device. In this case, any standard app for determining a current device location will become useless. Fortunately, this procedure is illegal and very few people will take on this work.

What if One of the Above Conditions is Unachievable?

1. 

Launch Tracker

Activate SS7 PL Tracker online from any section of this website. To do this, you must specify a phone number in international format and click the “Find” button.

Location Obtaining

Initiating a remote interception of a cellular signal by phone number and decrypting received data. The process is fully automated and doesn’t require any involvement.

Tracker Confirmation

Message “Success” in the dialog window means that your Android device location has been discovered and you can obtain its current location on detailed map after subscription purchasing.

Wallet Replenishment

Add funds to your account balance with one of the supported methods. After 3 confirmations from Blockchain, your funds will be available for depositing.

Customer Support

PL Tracker Team values each client, pays special attention to feature accuracy and strives towards constant service improvement.

Satisfaction Level

That’s the very number of clients willing to use this service once again, according to a recent poll. We appreciate this figure.

Frequently asked question

• What Android devices are compatible with PL Tracker? This software package is compatible with any mobile devices and cellular providers that offer GSM compatibility.
• Is this software package capable of determining the exact location? Due to their operational principles, GPS satellites don’t allow determining the exact object location. This measure is meant to ensure military security. That’s why indicators will always differ by several square meters.
• What notifications will be send to an Android Device? When SS7 cellular network vulnerability is exploited, it doesn’t affect a target device’s performance. Thus, a current user will receive zero extra notifications, and won’t notice any operational anomalies.
• How much time does a location determining session take? An operation can be completed in 2-to-10 minutes. It depends on cellular tower deployment density, as well as on security degree of a carrier’s server side.
• In what cases should the software package be used? If you can’t determine device location using the built-in “Find My Android” feature. Please note that PL Tracker will help only in determining your device location – you’ll have to retrieve it on yourself or aided by law enforcement agencies.

If you have any questions please do not hesitate to ask. Your suggestions and ideas are important to us – feel free to leave some in the Feedback Section or contact our Customer Support Team.

Hi,
It looks like I have a similar problem as topic started.
I have modified graddle.properties as theyasirahmad suggested, but that did not help.

How to reproduce:

1. clone the repo
2. yarn install && yarn run start in example/ folder
3. in another terminal run npx react-native run-android
   as a result I get a lot of errors as above:
