在Android 10上使用action_call意图拨打电话无效

问题描述

这适用于早期版本的android，但在android 10上不再适用。任何想法如何解决这个问题。任何帮助将不胜感激 。我已经尝试使用来自telecomManager的intent action_call和placeCall。

socket

解决方法

尝试添加callIntent.setFlags（FLAG_ACTIVITY_NEW_TASK）;

您是否要从后台服务开始通话？

Android 10仅限从后台启动活动。对此有一些排除。在我看来，“ SYSTEM_ALERT_WINDOW”权限是最简单的权限。

private void RequestPermission() {
        // Check if Android M or higher
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            // Show alert dialog to the user saying a separate permission is needed
            // Launch the settings activity if the user prefers
            Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,Uri.parse("package:" + getActivity().getPackageName()));
            startActivityForResult(intent,ACTION_MANAGE_OVERLAY_PERMISSION_REQUEST_CODE);
        }
    }

@Override
public void onActivityResult(int requestCode,int resultCode,@Nullable Intent data) {
    super.onActivityResult(requestCode,resultCode,data);

    if (requestCode == ACTION_MANAGE_OVERLAY_PERMISSION_REQUEST_CODE) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            if (!Settings.canDrawOverlays(getContext())) {
                PermissionDenied();
            }
            else
            {
             //Permission Granted-System will work
        }

    }
}

如果在设置呼叫前未选择帐户，则需要额外发送一个帐户句柄。

  try {
            List<PhoneAccountHandle> phoneAccountHandleList = TelecomUtil.getTelecomManager(context).getCallCapablePhoneAccounts();
            int simCard = getSimSelection(context);

            // Create call intent
            Intent callIntent = new Intent(Intent.ACTION_CALL,Uri.parse("tel:" + Uri.encode(number)));

            if (phoneAccountHandleList != null && !phoneAccountHandleList.isEmpty()) {
                callIntent.putExtra(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE,phoneAccountHandleList.get(simCard));
            }
//            // Handle sim card selection
            Timber.d("simcard %s",simCard);
            if (simCard != -1) callIntent.putExtra("com.android.phone.extra.slot",simCard);
//            // Start the call
            context.startActivity(callIntent);

        } catch (SecurityException e) {
            Toast.makeText(context,"Couldn't make a call due to security reasons",Toast.LENGTH_LONG).show();
        } catch (NullPointerException e) {
            Toast.makeText(context,"Couldnt make a call,no phone number",Toast.LENGTH_LONG).show();
        }
