答案 0 :(得分：1)
改变..（参见DEFALT更改为DEFAULT类别）
答案 1 :(得分：1)
问题在于定义活动名称不匹配。
在清单中，您已定义活动名称为menu而非MENU
<activity android:name=".menu"
android:label="@string/app_name">
但是在代码startActivity(new Intent("com.basic.android.MENU"));中你想要启动一个未定义的活动菜单，因为在清单菜单中定义了菜单但未定义菜单
活动名称区分大小写
答案 2 :(得分：0)
在调用startActivity之前（new Intent（“com.basic.android.MENU”））取消你的logoTimer
像
logoTimer.cancel();
startActivity(new Intent("com.basic.android.MENU"))
//
public void toCallActivity() {
TimerTask startNewActivity;
final Handler handler = new Handler();
Timer timer = new Timer();
startNewActivity = new TimerTask() {
@Override
public void run() {
// TODO Auto-generated method stub
handler.post(new Runnable() {
public void run() {
try {
timer.cancel();
startActivity(new Intent("com.basic.android.MENU"));
} catch (Exception e) {
// TODO Auto-generated catch block
}
}
});
}
};
timer.schedule(startNewActity, 0,5000);
}

Android Studio区分大小写，因此应该可以使用。
