獲取聯繫人時的Android棉花糖安全異常

Question

任何人都可以請我建議我在我的代碼中進行哪些更改以從Android聯繫人列表中檢索聯繫人。這是我寫的是工作完美的棒棒糖和下方，但對於上述棒棒糖它崩潰說安全例外的邏輯..

Answer 1

請參考https://developer.android.com/training/permissions/requesting.html

「，開始在在Android 6.0（API等級23），用戶授予權限到應用程序運行時應用程序，而不是安裝應用程序時。「

權限被分類爲正常且有危險。

下面的代碼檢查，如果該應用程序有權限讀取用戶的聯繫人，並在必要時請求權限：

// Here, thisActivity is the current activity 
if (ContextCompat.checkSelfPermission(thisActivity, 
      Manifest.permission.READ_CONTACTS) 
    != PackageManager.PERMISSION_GRANTED) { 

// Should we show an explanation? 
if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, 
     Manifest.permission.READ_CONTACTS)) { 

    // Show an expanation 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. 

} else { 

    // No explanation needed, we can request the permission. 

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

    // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an 
    // app-defined int constant. The callback method gets the 
    // result of the request. 
} 
}
