Question

所以，在过去的两天里，我在尝试连接时遇到了这个错误。

尝试UDP，TCP和Httprequest / Httppost。

我们尝试在两台设备上使用APK

尝试时使用WIFI，我们添加了3个权限，即使据我所知，我只需要互联网权限。添加权限而不是错误。

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

编辑：我还添加了“android：sharedUserId =”android.uid.system“”，这是完全相同的错误......仍然......

编辑：在此处添加清单：

<?xml version="1.0" encoding="utf-8"?>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme"
    android:sharedUserId="android.uid.system">

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



    <uses-permission android:name="android.permissions.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permissions.CHANGE_WIFI_STATE" />

    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

编辑：更改后的清单：

            <category android:name="android.intent.category.LAUNCHER" />

编辑：MainActivity更新：

public class MainActivity extends Activity {

LinearLayout rl;

private TextView ErrorHandler;

StringBuffer buffer;

List<NameValuePair> nameValuePairs;

    et = new TextView(this);
    pass = new TextView(this);
    et.setVisibility(View.VISIBLE);
    pass.setVisibility(View.VISIBLE);

    et.setText("aici");
    pass.setText("aici");

    btn = new Button(this);
    btn.setVisibility(View.VISIBLE);
    btn.setText("Apasa!");

    btn.setOnClickListener(new View.OnClickListener() {

        }
    });


    rl.addView(et);
    rl.addView(pass);
    rl.addView(btn);

}



private int login() {

    int resp = 1;

    try {

        httpclient = new DefaultHttpClient();

                .getText().toString().trim()));

                .getText().toString().trim()));

        ResponseHandler<String> responseHandler = new BasicResponseHandler();

        } else if (response.equalsIgnoreCase("No Such User Found")) {

            resp = 0;

        }

    } catch (Exception e) {
        System.out.println("Exception : " + e.getMessage());
    }

    return resp;
}

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

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

}

兄弟似乎对您的清单文件有疑问将您的许可放在应用程序标记之上，如果问题仍然存在，请告诉我

[编辑]

 <uses-permission android:name="android.permissions.ACCESS_WIFI_STATE" />
 <uses-permission android:name="android.permissions.CHANGE_WIFI_STATE" />

更改权限权限并运行代码

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