デバイスバージョン21以降でアプリを実行しているときにエラーが発生しましたか？

Question

私はユーザーの場所を検出するためのgoofenceアプリケーションを実装していますが、21以上のデバイスをサポートしていないため、すべてのデバイスでどのように実装するのですか。ユーザの位置をreceving、そこから更新をrecevingため

MainActivity.java

 Location location = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient); 

          if (location == null) { 
           LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, MainActivity.this); 

コード。
これは私の主なアクティビティクラスです。また、権限を追加してもエラーが表示されます。
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

Error:(100, 64) error: incompatible types: <anonymous ConnectionCallbacks> cannot be converted to Context. 
after implementing permission i get error like this.

Answer 1

問題は、あなたがそのような行為を容易にするために、実行時のアクセス権を有効にする必要があるということです。

if (ContextCompat.checkSelfPermission(context, 
      Manifest.permission.ACCESS_FINE_LOCATION) 
    != PackageManager.PERMISSION_GRANTED) { 

     ActivityCompat.requestPermissions(thisActivity, 
      new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 
      12000); 

} 

このページをお読みください ：https://developer.android.com/training/permissions/requesting.html はアプリが見えるようになる。このチェックを実行し、

Answer 2

1. まずコールcheckSelfPermission：許可が、その後付与されている場合

   は、他の場所
   をフェッチ、以下のステップ2に進みます。許可を

2. 要求：

   int PERMISSION_REQ_LOCATION = 0100; 
   
   requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, PERMISSION_REQ_LOCATION); 
   

3. 上書き許可を求める後の結果をチェックするには、この方法：API 25に

   @Override 
   public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { 
   switch (requestCode) { 
       case PERMISSION_REQ_LOCATION: 
        //TODO fetch location 
        break; 
       default: 
        super.onRequestPermissionsResult(requestCode, permissions, grantResults); 
       } 
   }
