我有一个使用 phonegap 2.1 的基于 phonegap 的应用程序，我添加了对后退按钮的处理。

@Override
public void onBackPressed() {

    // Move the application to background on back button press.

    if (!moveTaskToBack(false)) {

        Log.e("myApp", "Failed to move the app to background");

    }

    return;

}

现在在带有 Android 4.1.1 的 Samsung Tab 上，当按下返回或主页按钮时，该应用程序会被终止。但是，相同的代码适用于具有 Android 4.2.2 的 Nexus 设备

这是日志猫
