我正在使用ActionBarSherlock,片段和Admob广告进行应用。该应用程序没有广告正常工作。在我更新清单以包含广告活动和更正权限后,我将Admob jar文件添加到项目后,它也可以正常工作。当我尝试将广告添加到片段布局时,它会崩溃。然后onCreateOptionsMenu抛出一个空指针异常。
这是片段的xml:

崩溃的代码:(尝试访问菜单项miAdvance时出现空指针异常):
@Override
public boolean onCreateOptionsMenu(Menu menu) {
new MenuInflater(this).inflate(R.menu.main, menu);
this.menu = menu;
miAdvance = menu.findItem(R.id.menu_automatic);
miDifficulty = menu.findItem(R.id.menu_settings);
updateMenuTitles(miAdvance,miDifficulty);
return(super.onCreateOptionsMenu(menu));
}
/*
* as the name implies
* updates titles to match settings of Difficulty and Advance settings
*/
private void updateMenuTitles() {
switch (Difficulty) {
case DIFFICULTY_BASIC:
miDifficulty.setTitle("Basic");
break;
case DIFFICULTY_ADVANCED:
miDifficulty.setTitle("Advanced");
break;
case DIFFICULTY_ADVANCED_AND_BASIC:
miDifficulty.setTitle("All");
break;
default:
miDifficulty.setTitle("Difficulty");
break;
}
switch (Automatic) {
case ADVANCE_MANUAL:
miAdvance.setTitle("Manual");
break;
case ADVANCE_AUTOMATIC:
miAdvance.setTitle("Auto");
break;
default:
miAdvance.setTitle("Progress");
break;
}
}

确保你做了一个干净的构建。
您发布的任何配置或代码都没有错。我怀疑您在构建中遇到了不匹配的资源类。
