Studio 2.0 Beta 4 Available in Canary Channel - Android Tools Project Site. We've just pushed Android Studio 2.0 Beta 4 to the canary channel, as well as 2.0.0-beta4 of the Gradle plugin to jcenter. Please note that in this build, the "Instant Run" settings are all restored to defaults. Go to Settings > Build, Execution, Deployment > Instant Run if you want to tweak them again.
The reason we had to do this is that these settings are (currently) actually per project settings, not per user. But this is not what many users expected (so they'd tweak the settings in one project and then be surprised when in another project the values were different). So we've now turned the settings into global settings instead. Bug fixes included: Note: After updating to beta 4, you'll also need to update your projects to the latest Gradle plugin (2.0.0-beta4) if you want to use Instant Run.
If all goes according to plan, we hope to roll this out to the beta channel in a few days. Thanks for testing our preview builds, and please continue reporting bugs! Installation Problems? Android - Animating markers on Google Maps V2. Географические координаты. Географи́ческие координа́ты определяют положение точки на земной поверхности или, более широко, в географической оболочке. Географические координаты строятся по принципу сферических. Аналогичные координаты применяются на других планетах, а также на небесной сфере[1]. Широта[править | править вики-текст] Из-за отличия формы Земли от шара, географическая широта точек несколько отличается от их геоцентрической широты, то есть от угла между направлением на данную точку из центра Земли и плоскостью экватора.
Широту места можно определить с помощью таких астрономических инструментов как секстант или гномон (прямое измерение), также можно воспользоваться системами GPS или ГЛОНАСС (косвенное измерение). Долгота[править | править вики-текст] Долгота́ — двугранный угол λ между плоскостью меридиана, проходящего через данную точку, и плоскостью начального нулевого меридиана, от которого ведётся отсчёт долготы. От долготы зависит местное солнечное время. Высота[править | править вики-текст] в Навигация.

Setting Up Google Play Services | Google APIs for Android | Google Developers. To develop an app using the Google Play services APIs, you need to set up your project with the Google Play services SDK. If you haven't installed the Google Play services SDK yet, go get it now by following the guide to Adding SDK Packages. To test your app when using the Google Play services SDK, you must use either: A compatible Android device that runs Android 2.3 or higher and includes Google Play Store.The Android emulator with an AVD that runs the Google APIs platform based on Android 4.2.2 or higher.
Add Google Play Services to Your Project Select your development environment below and add Google Play services to your project by following the steps provided. Android Studio To make the Google Play services APIs available to your app: You can now begin developing features with the Google Play services APIs. Selectively compiling APIs into your executable In versions of Google Play services prior to 6.5, you had to compile the entire package of APIs into your app. With these lines: Other. Getting the Last Known Location. Using the Google Play services location APIs, your app can request the last known location of the user's device. In most cases, you are interested in the user's current location, which is usually equivalent to the last known location of the device. Specifically, use the fused location provider to retrieve the device's last known location. The fused location provider is one of the location APIs in Google Play services. It manages the underlying location technology and provides a simple API so that you can specify requirements at a high level, like high accuracy or low power.
It also optimizes the device's use of battery power. This lesson shows you how to make a single request for the location of a device using the getLastLocation() method in the fused location provider. Set Up Google Play Services To access the fused location provider, your app's development project must include Google Play services. Specify App Permissions Apps that use location services must request location permissions. Google Maps Android API | Google Developers.
