我是 android 开发的新手，我需要帮助。我试图在我的应用程序中连接https://www.google.cz/并且它给了我一个错误：

http连接javajava.lang.SecurityException中的错误：权限被拒绝（缺少INTERNET权限？）

Java代码：

    public class SuplAct extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {

    try{    
        super.onCreate(savedInstanceState);

        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.activity_supl);

        StrictMode.ThreadPolicy policy = new
        StrictMode.ThreadPolicy.Builder()
        .permitAll().build();
        StrictMode.setThreadPolicy(policy);

        TextView MyTextview = (TextView)findViewById(R.id.hello_world);

        try{
        HttpClient  httpclient = new DefaultHttpClient() ;
        HttpPost httppost = new HttpPost("https://www.google.cz/");
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        InputStream webs = entity.getContent();
        try{
            BufferedReader reader = new BufferedReader(new InputStreamReader (webs,"iso-8859-1"),8); 
            MyTextview.setText(reader.readLine());
            webs.close();

        }catch(Exception e){Log.e("log_tag","Error converting result"+e.toString() );}
    }catch(Exception e){Log.e("log_tag","Error in http connection"+e.toString() );}
    }catch(Exception e){Log.e("ERROR","ERROR in the code"+e.toString() );
    e.printStackTrace();}   
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.supl, menu);
        return true;
    }

}

显现：

检查您的权限语法：

<uses-permission android:name = "android.premission.INTERNET">

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