呼び出しには、ユーザーによって拒否される可能性のある権限が必要です

5分ごとにユーザーの位置情報の更新を送信するアプリケーションを作成しようとしています。私のコードは正常に動作していると思いますが、アプリケーションで使用されている権限に関するエラーが表示されます。マニフェストファイルにアクセス許可を追加したことは確かです。誰かが間違っていることを教えてもらえますか?これが私のコードです。

MainActivity.Java

LocationManager locationManager ;
String provider;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Getting LocationManager object
    locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);

    // Creating an empty criteria object
    Criteria criteria = new Criteria();

    // Getting the name of the provider that meets the criteria
    provider = locationManager.getBestProvider(criteria, false);

    if(provider!=null && !provider.equals("")){

        // Get the location from the given provider
        Location location = locationManager.getLastKnownLocation(provider);
        locationManager.requestLocationUpdates(provider,5*60*1000,0,this);

        if(location!=null)
            onLocationChanged(location);
        else
            Toast.makeText(getBaseContext(), "Location can't be retrieved", Toast.LENGTH_SHORT).show();

    }else{
        Toast.makeText(getBaseContext(), "No Provider Found", Toast.LENGTH_SHORT).show();
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public void onLocationChanged(Location location) {
    // Getting reference to TextView tv_longitude
    TextView tvLongitude = (TextView)findViewById(R.id.tv_longitude);

    // Getting reference to TextView tv_latitude
    TextView tvLatitude = (TextView)findViewById(R.id.tv_latitude);

    // Setting Current Longitude
    tvLongitude.setText("Longitude:" + location.getLongitude());

    // Setting Current Latitude
    tvLatitude.setText("Latitude:" + location.getLatitude() );
}

@Override
public void onProviderDisabled(String provider) {
    // TODO Auto-generated method stub
}

@Override
public void onProviderEnabled(String provider) {
    // TODO Auto-generated method stub
}

@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
    // TODO Auto-generated method stub
}

}

呼び出しにはユーザーが拒否する許可が必要ですこれらの行でエラーが発生しています-

Location location = locationManager.getLastKnownLocation(provider);
        locationManager.requestLocationUpdates(provider,5*60*1000,0,this);

私のAndroidManifestはこんな感じ

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

<application
    Android:icon="@mipmap/ic_launcher"
    Android:label="@string/app_name"
    Android:theme="@style/AppTheme" >
    <activity
        Android:name=".MainActivity"
        Android:label="@string/title_activity_main" >
        <intent-filter>
            <action Android:name="Android.intent.action.MAIN" />
            <category Android:name="Android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

どのSDKを使用していますか? Marshmallowを使用する場合は、ユーザーがすべてのロケーションコールに許可を与えていることを確認する必要があります。

ご覧ください こちら

次のようにする必要があります。

  if (ContextCompat.checkSelfPermission( this,Android.Manifest.permission.ACCESS_COARSE_LOCATION ) != PackageManager.PERMISSION_GRANTED )
{
    ActivityCompat.requestPermissions(
        this,
        new String [] { Android.Manifest.permission.ACCESS_COARSE_LOCATION },
        LocationService.MY_PERMISSION_ACCESS_COURSE_LOCATION
    );
}

まだ許可していない場合は許可をリクエストしてください。

詳細については、上記のリンクを確認してください。

私のコードを試してください:

public class MainActivity extends AppCompatActivity {

    /* GPS Constant Permission */
    private static final int MY_PERMISSION_ACCESS_COARSE_LOCATION = 11;
    private static final int MY_PERMISSION_ACCESS_FINE_LOCATION = 12;

    /* Position */
    private static final int MINIMUM_TIME = 10000;  // 10s
    private static final int MINIMUM_DISTANCE = 50; // 50m

    /* GPS */
    private String mProviderName;
    private LocationManager mLocationManager;
    private LocationListener mLocationListener;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...

        mLocationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

        // Get the best provider between gps, network and passive
        Criteria criteria = new Criteria();
        mProviderName = mLocationManager.getBestProvider(criteria, true);

        // API 23: we have to check if ACCESS_FINE_LOCATION and/or ACCESS_COARSE_LOCATION permission are granted
        if (ContextCompat.checkSelfPermission(this, Android.Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED
                || ContextCompat.checkSelfPermission(this, Android.Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {

            // No one provider activated: Prompt GPS
            if (mProviderName == null || mProviderName.equals("")) {
                startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));
            }

            // At least one provider activated. Get the coordinates
            switch (mProviderName) {
                case "passive":

        } else {

            // The ACCESS_COARSE_LOCATION is denied, then I request it and manage the result in
            // onRequestPermissionsResult() using the constant MY_PERMISSION_ACCESS_FINE_LOCATION

                        new String[] { Manifest.permission.ACCESS_FINE_LOCATION },
                        MY_PERMISSION_ACCESS_FINE_LOCATION);
            }

        }
    }

これは私のために働いた

if (ActivityCompat.checkSelfPermission(this, Android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
   Toast.makeText(YourService.this, "First enable LOCATION ACCESS in settings.", Toast.LENGTH_LONG).show();
   return;
}
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 100, 1, listener);

これを修正するために実行する必要がある一連の手順を以下に示します

メインアクティビティ.Java

if (ContextCompat.checkSelfPermission(this,
 Android.Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED
 || ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) 
 == PackageManager.PERMISSION_GRANTED) {         
locationManager.requestLocationUpdates
 (locationManager.requestLocationUpdates(provider,5*60*1000,0,this);
}//end of if

ここで、build.gradleも更新する必要があります

dependencies{
 ------------- //your pre-generated code
compile 'com.Android.support:support-v4:23.0.1'
}

this はAndroid.Developersが言っていることです。

アプリケーション設定から許可を与えることを忘れないでくださいエミュレーターを使用している場合は、プロンプトが表示されない可能性があるためです
