java.lang.SecurityException：权限被撤销，权限被撤销 android.permi

Question

我已经添加了要显示的权限，但仍然没有工作，（不在棉花糖下），请帮助将代码版本更新为有效代码的新版本。整个错误是：java.lang.SecurityException：Permission Denial：starting Intent { act=android.intent.action.CALL dat=tel:xxxxx flg=0x10000000 cmp=com.android.server.telecom/.components.UserCallActivity } 来自 ProcessRecord{80edffb 11112:kg.o.assist/u0a86} (pid=11112 , uid=10086) 撤销权限 android.permission.CALL_PHONE

            Intent intent = new Intent(Intent.ACTION_DIAL);
            intent.setData(Uri.parse("tel:" + "phone_number"));

            if (Build.VERSION.SDK_INT > 23) {
                startActivity(intent);
            } else {

                if (ActivityCompat.checkSelfPermission(PurchaseItemDetails.this,
                        Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
                    Toast.makeText(YourActivity.this, "Permission Not Granted ", Toast.LENGTH_SHORT).show();
                } else {
                    final String[] PERMISSIONS_STORAGE = {Manifest.permission.CALL_PHONE};
                    ActivityCompat.requestPermissions(YourActivity.this, PERMISSIONS_STORAGE, 9);

Answer 2

android.permission.CALL_PHONE 是危险的权限，所以应该在运行时请求 https://developer.android.com/reference/android/Manifest.permission#CALL_PHONE。详情请查看https://developer.android.com/training/permissions/requesting.html

Answer 3

将 CALL 更改为 DIAL，现在可以正常工作了。
