錯誤permision ACCESS_FIND_LOCATION

Question

我使用權限ACCESS_FINE_LOCATION但是當run.error：要求ACCESS_FINE_LOCATION permission 爲什麼？

在此先感謝。

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

Answer 1

ACCESS_FINE_LOCATION和ACCESS_COARSE_LOCATION不是添加此運行permsiion像下面的代碼時需要試圖讓位置 所以加這兩個清單文件的權限，以及如果您的定位的Android 6.0及以上版本都允許

String permission = android.Manifest.permission.ACCESS_FINE_LOCATION; 
      if (ActivityCompat.checkSelfPermission(SearchCityClass.this, permission) 
        != PackageManager.PERMISSION_GRANTED && ActivityCompat. 
        checkSelfPermission(SearchCityClass.this, android.Manifest.permission.ACCESS_COARSE_LOCATION) 
        != PackageManager.PERMISSION_GRANTED) { 
       ActivityCompat.requestPermissions(SearchCityClass.this, new String[] 
         {permission}, PERMISSION_GPS_CODE); 

      } 

現在處理permisiion結果

@Override 
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, 
             @NonNull int[] grantResults) { 
    super.onRequestPermissionsResult(requestCode, permissions, grantResults); 
    if (requestCode == PERMISSION_GPS_CODE) { 
     if (grantResults[0] == PackageManager.PERMISSION_GRANTED) { 


      Toast.makeText(this, "location_permission_granted ", Toast.LENGTH_SHORT).show(); 

     } else { 

      Toast.makeText(this, "location_permission_not_granted ", Toast.LENGTH_SHORT).show(); 
     } 
    } 

} 

Answer 2

您是否在代碼中編寫運行時權限？從Android 6.0開始，對於清單中聲明的​​每個權限，還必須向用戶提出運行時間。

private void requestLocationPermission() { 

    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) { 
     ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, LOCATION_PERMISSION_CODE); 
    } 
} 

也處理用戶的響應，以及：

@Override 
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { 
    switch (requestCode) { 
     case LOCATION_PERMISSION_CODE: { 
      //If permission is granted 
      if (grantResults.length > 0 && grantResults[0] != PackageManager.PERMISSION_GRANTED) { 
       Toast.makeText(this, "Oops you just denied the permission", Toast.LENGTH_LONG).show(); 
      } 
      return; 
     } 
    } 
}
