Android Marshmallow API 23で緯度と経度が表示されない

Question

Android Marshmallow API 23で緯度と経度の値が0.0になるという問題が発生します。その他のAPIは正常に動作しています。現在の位置情報を取得していないGoogleマップに問題があります。

public Location getLocation() {

アンドロイドたManifest.xml

<uses-permission-sdk-23 android:name="android.permission.ACCESS_COARSE_LOCATION"/> 
<uses-permission-sdk-23 android:name="android.permission.ACCESS_FINE_LOCATION"/> 

Answer 1

あなたが手動で設定

から許可を有効にするために持っているよりも、これを実装していない場合は、マシュマロ Hereで、実行時のアクセス許可を実装しており、

Googleコンソールアカウント

から取得する AndroidManifest.xmlのAPIキーを確認してください

<meta-data 
     android:name="com.google.android.maps.v2.API_KEY" 
     android:value="YOUR_KEY" />

Implement run time permission for mashmallow 
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 
     checkLocationPermission(); 
    } else { 
     Log.d("onCreate", "Google Play Services available."); 
    } 
public boolean checkLocationPermission() { 
     if (ContextCompat.checkSelfPermission(getActivity(), 
       Manifest.permission.ACCESS_FINE_LOCATION) 
       != PackageManager.PERMISSION_GRANTED) { 

      // Asking user if explanation is needed 
      if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), 
        Manifest.permission.ACCESS_FINE_LOCATION)) { 

       // Show an explanation to the user *asynchronously* -- don't block 
       // this thread waiting for the user's response! After the user 
       // sees the explanation, try again to request the permission. 

       //Prompt the user once explanation has been shown 
       new AlertDialog.Builder(getActivity()) 
         .setTitle("Permission needed") 
         .setMessage("Please allow permission to access your location to continue service") 
         .setPositiveButton("OK", new DialogInterface.OnClickListener() { 
          @Override 
          public void onClick(DialogInterface dialogInterface, int i) { 
           //Prompt the user once explanation has been shown 
           ActivityCompat.requestPermissions(getActivity(), 
             new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 
             MY_PERMISSIONS_REQUEST_LOCATION); 
          } 
         }) 
         .create() 
         .show(); 

      } else { 
       // No explanation needed, we can request the permission. 
       ActivityCompat.requestPermissions(getActivity(), 
         new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 
         MY_PERMISSIONS_REQUEST_LOCATION); 
      } 
      return false; 
     } else { 
      return true; 
     } 
    }
