Android-M ie，API 23引入Runtime Permissions以减少Android设备中的安全漏洞，用户现在可以在运行时直接管理应用程序权限。如果用户拒绝您的应用程序的特定权限，则必须获取它通过询问您在查询中提到的权限对话框。

因此请在行动前检查，即检查您是否有权访问资源link，如果您的应用程序没有该特定权限，您可以请求权限link并处理权限请求回复如下。

@Override
public void onRequestPermissionsResult(int requestCode,
        String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted, yay! Do the
                // contacts-related task you need to do.

               } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
            }
            return;
        }

        // other 'case' lines to check for other
        // permissions this app might request
    }
}

最后，如果您计划使用新版本以避免强行关闭，那么通过behavior changes是一个很好的做法：）

答案 1 :(得分：1)

您的应用程序看起来没有正确的权限（READ_EXTERNAL_STORAGE）。

问题是在Android 6中你必须在运行时检查权限。你可以在这里找到更多信息：

答案 2 :(得分：1)

您需要在RunTime

请求权限

从API 23开始，您必须在运行时请求权限，因此不会自动授予Manifest的权限。

更多信息：http://developer.android.com/training/permissions/requesting.html

请记住，有时您必须向用户解释为什么您的应用程序需要这些权限。
