Android的东西 - 不能使用Awareness API [英] Android Things - can't use Awareness API

问题描述

我在手机上使用较低版本（9.4.0）的相同代码，但出于某种原因，它不适用于RPi3？我的build.gradle

  compile'c​​om.google.android.gms：play-services：10.0.0'
提供'com.google.android.things：androidthings：0.4-devpreview'
  

清单权限

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

该方法

  private void getWeather（）{
 
 //首先检查权限
 if（ContextCompat.checkSelfPermission（this，Manifest.permission.ACCESS_FINE_LOCATION）
！= PackageManager .PERMISSION_GRANTED）{
 
 Log.e（标记，尚未授予的精细位置权限）; 
 
 ActivityCompat.requestPermissions（this，new String [] {Manifest.permission.ACCESS_FINE_LOCATION}，MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION）; 
 
} else {
 System.out.println（else of getWeather（））; 
 Log.i（TAG，已授予精细位置权限）; 
 
 // Weather 
 Awareness.SnapshotApi.getWeather（mGoogleApiClient）.setResultCallback（new ResultCallback< WeatherResult>（）{
 @Override 
 public void onResult（@NonNull WeatherResult weatherResult）{
 if（！weatherResult.getStatus（）。isSuccess（））{
 Log.e（TAG，Could not detect weather info）; 
 mWeatherTextView.setText（无法检测天气信息）; 
 mWeatherTextView.setTextColor（Color.RED）; 
 System.out.println（NO WEATHER INFO）; 
 return; 
} 
 System.out.println（WEATHER INFO REC'D）; 
 Weather weather = weatherResult.getWeather（）; 
 mWeatherTextView.setText（weather.toString（））; 
 } 
 }）; 
 
 
  

logcat

由于某种原因， 。该应用程序不会崩溃，我有一个OnClickListener调用getWeather（），所以我可以重复点击，但从来没有得到任何快照数据。我使用了与手机相同的API密钥...

根据 docs Awareness API在AndroidThings&我见过项目是人们声称使用了附近和列表中的其他API。有人在AndroidThings上的Awareness API上获得成功吗？

在更新服务11.0.0后，应用程序立即关闭& logcat现在显示

解决方案

最小播放服务客户端版本 11.0.0 。这是推出Play服务的物联网变体的版本。这在支持Google服务的文档中有详细说明。

为了获得最佳效果，您应该将库版本与您正在运行的预览版捆绑的确切版本进行匹配。您可以在发行说明上找到这些版本号。

I have the same code with a lower version (9.4.0) working on the phone but for some reason it won't work on RPi3? My build.gradle

compile 'com.google.android.gms:play-services:10.0.0'
provided 'com.google.android.things:androidthings:0.4-devpreview'

The manifest permissions

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

The method

private void getWeather() {

    // Check for permission first
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
            != PackageManager.PERMISSION_GRANTED) {

        Log.e(TAG, "Fine Location Permission not yet granted");

        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);

    } else {
        System.out.println("else of getWeather()");
        Log.i(TAG, "Fine Location permission already granted");

        // Weather
        Awareness.SnapshotApi.getWeather(mGoogleApiClient).setResultCallback(new ResultCallback<WeatherResult>() {
                    @Override
                    public void onResult(@NonNull WeatherResult weatherResult) {
                        if (!weatherResult.getStatus().isSuccess()) {
                            Log.e(TAG, "Could not detect weather info");
                            mWeatherTextView.setText("Could not detect weather info");
                            mWeatherTextView.setTextColor(Color.RED);
                            System.out.println("NO WEATHER INFO");
                            return;
                        }
                        System.out.println("WEATHER INFO REC'D");
                        Weather weather = weatherResult.getWeather();
                        mWeatherTextView.setText(weather.toString());
                    }
                });
    }
}

The logcat

For some reason it stops after telling me the permission is granted. The app doesn't crash though, I have an OnClickListener that calls getWeather() so I can repeatedly click but never get any snapshot data. I'm using the same API key that works on the phone...

According to the docs the Awareness API is supported on the AndroidThings & I've seen projects were people claim to have used Nearby & other APIs in the list. Has anyone had success with the Awareness API on AndroidThings?

After updating to play services 11.0.0 the app opens the immediately closes & the logcat now shows

解决方案

Overall, Android Things requires a minimum Play Services client version of 11.0.0. This is the version where the IoT variant of Play Services was introduced. This is noted in the documentation under Support for Google Services.

For best results, you should match the library version to the exact version bundled with the preview release you are running. You can find those version numbers on the Release Notes.
