Android 6.0 申请权限Permission Denial: reading com.android.providers.media.MediaProvider

解决办法：
1:在oncreate方法中，在setcontentview()下面加上下面代码

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            int hasCallPhonePermission = checkSelfPermission(Manifest.permission.CALL_PHONE);
            List<String> permissions = new ArrayList<String>();
            if (hasCallPhonePermission != PackageManager.PERMISSION_GRANTED) {
                permissions.add(Manifest.permission.CALL_PHONE);
            } else {
                AbSharedUtil.putString(this, "storage", "true");
            }

            if (!permissions.isEmpty()) {
                requestPermissions(permissions.toArray(new String[permissions.size()]), REQUEST_CODE_SOME_FEATURES_PERMISSIONS);
            }
        }else {//小于6.0
            AbSharedUtil.putString(this,"storage", "true");
        }

2:在oncreate以外加入下面代码

public static int  REQUEST_CODE_SOME_FEATURES_PERMISSIONS=1;
    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
            case REQUEST_CODE_SOME_FEATURES_PERMISSIONS: {
                for (int i = 0; i < permissions.length; i++) {
                    if (grantResults[i] == PackageManager.PERMISSION_GRANTED) {
                        Log.e("TTT","Permissions --> " + "Permission Granted: " + permissions[i]);
                    } else if (grantResults[i] == PackageManager.PERMISSION_DENIED) {
                        Log.e("TTT","Permissions --> " + "Permission Denied: " + permissions[i]);
                    }
                }
            }
            break;
            default: {
                super.onRequestPermissionsResult(requestCode, permissions, grantResults);
            }
        }
    }
