android - 电话间隙问题

Question

我有问题。当您在设备上启动应用程序时。

当我按下“返回”按钮时。

安卓清单：

            </intent-filter>
        </activity>
    </application>
</manifest>

主要活动：

package com.example.firstgap;

import android.os.Bundle;
import org.apache.cordova.DroidGap;

public class MainActivity extends DroidGap {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.loadUrl("file:///android_asset/www/index.html");
    }
}

有什么问题？请帮忙！！！

您的清单中有错误的启动器活动尝试将其更改为：

<activity
    android:name="com.example.firstgap.MainActivity"
    android:label="@string/app_name"
    android:configChanges="orientation|keyboardHidden"  >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
<activity>

你必须实例化你com.example.firstgap.MainActivity的 insthead org.apache.cordova.DroidGap。
