Question

我正在编写一个通过TCP Socket发送消息的应用程序。我正在努力获得互联网许可。（API 26是目标）

socket EACCESS permission denied

我已在我的Manfest中设置：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.seb.sebastien.opengardenirc">

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.persmission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

    <application

当我使用API26时，我必须在代码中添加权限检查以确保它正常工作：

if (shouldAskPermission()) {
            Log.d(TAG, "Permission is required");
            String[] PERMISSIONS_STORAGE = {
                    Manifest.permission.ACCESS_NETWORK_STATE,
                    Manifest.permission.INTERNET,
                    Manifest.permission.ACCESS_WIFI_STATE
            };

            int permission_internet = ActivityCompat.checkSelfPermission(this, Manifest.permission.INTERNET);
            int permission_network = ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_NETWORK_STATE);
            int permission_wifi = ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_WIFI_STATE);

            Log.d(TAG, "Package Manager: " + PackageManager.PERMISSION_GRANTED);
            Log.d(TAG, "INTERNET : " + permission_internet);
            Log.d(TAG, "NETWORK : " + permission_network);
            Log.d(TAG, "WIFI : " + permission_wifi);

            if ((permission_internet != PackageManager.PERMISSION_GRANTED)
                    || (permission_network != PackageManager.PERMISSION_GRANTED)
                    || (permission_wifi != PackageManager.PERMISSION_GRANTED)){
                Log.d(TAG, "Asking for permission");
                // We don't have permission so prompt the user
                ActivityCompat.requestPermissions(
                        this,
                        PERMISSIONS_STORAGE,
                        REQUEST_CONNECTION_PERMISSION
                );
            } else {
                Toast.makeText(MainActivity.this, "Permission (already) Granted!", Toast.LENGTH_SHORT).show();
                Log.d(TAG, "Permission already granted");
                startTcpInAThread("str");
            }

        }

我还有抓住onRequestPermissionsResult的方法。

private boolean shouldAskPermission(){

        return(Build.VERSION.SDK_INT> Build.VERSION_CODES.LOLLIPOP_MR1);

    }

    @Override
    public void onRequestPermissionsResult(int permsRequestCode, String[] permissions, int[] grantResults){

        switch(permsRequestCode){
            case REQUEST_CONNECTION_PERMISSION:
                Log.d(TAG, "Permission granted result : " + grantResults[0]);
                Log.d(TAG, "Permission granted result : " + grantResults[1]);
                Log.d(TAG, "Permission granted result : " + grantResults[2]);


                boolean accepted = (grantResults[0]== PackageManager.PERMISSION_GRANTED)
                        && (grantResults[1]== PackageManager.PERMISSION_GRANTED)
                        && (grantResults[2]== PackageManager.PERMISSION_GRANTED);
                if(accepted) {
                    startTcpInAThread("str");
                } else {
                    Toast.makeText(getApplicationContext(), "Permissions issues!!!!", Toast.LENGTH_SHORT).show();
                }
                break;

        }

    }

首先，在检查权限时，我可以看到android.persmission.INTERNET未被授予。好的是，它会调用请求权限方法ActivityCompat.requestPermissions

我期待一个对话框出现，但我的理解是dlgbox只显示一些其他人不需要的权限请求。

我担心的是，当我获得onRequestPermissionsResult时，仍未获得许可。

有人知道如何授予互联网许可吗？

我还注意不要在同一个线程中运行网络访问。

此致

未授予互联网许可
