提交#10就是主人.然而,我最终意识到我在测试中没有遇到过的问题.
我最终将提交#5,然后慢慢重新执行每个提交的开发并不断调整它以确保它不会重新导致错误.现在我基本上回到了提交#10,但是有一些改变可以防止错误发生.
我现在想要使用我的更改创建提交#11.但是当我试图推动掌握时,我得到了
fatal: You are not currently on a branch.
To push the history leading to the current (detached HEAD)
state now, use
git push master HEAD:<name-of-remote-branch>
这是可以预料的.但是我如何才能真正实现这一目标呢？
我试过git push origin HEAD:master但后来得到了这个:
! [rejected] HEAD -> master (non-fast-forward)
error: failed to push some refs to 'https://github.com/tomhammond/sample.git'
hint: Updates were rejected because a pushed branch tip is behind its remote
hint: counterpart. Check out this branch and integrate the remote changes

add_index "completions", ["survey_id"], name: "index_completions_on_survey_id"
add_index "completions", ["survey_id"], name: "index_completions_on_survey_id_and_user_id", unique: true
我试过了
def change
remove_index "completions", ["survey_id"], name => "index_completions_on_survey_id_and_user_id"
end
和
def change
remove_index "completions", ["survey_id"], name: "index_completions_on_survey_id_and_user_id"
end
但这些似乎都不起作用.此迁移删除索引的正确语法是什么？我觉得这是基本的,我只是错过了一些愚蠢的东西.提前致谢!
我正在尝试按照Android 接收位置更新教程.示例代码在Github上.
一切都在工作,除了这一行:
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
这是一个cannot resolve method requestLocationUpdates错误.我在文档中没有看到任何内容,但我对Android很新,所以可能会遗漏一些东西:).
这是完整的代码.我出错的任何想法？谢谢!

我想以编程方式自动从我的rails应用程序在亚马逊上进行购买,因为我必须每周手动进行相同的购买.这将使用我自己的结算信息/帐户,而不是代表用户.
我搜索了他们的大部分API,发现你可以搜索一个项目,将它添加到购物车等等,但我似乎无法找到实际购买的方法.
有没有人知道通过API做到这一点的方法？它可以很好地自动化我们的手动过程.似乎它应该是可能的,因为https://zincapi.com/似乎促进了这一点.
这是几个星期前的工作,但现在我注意到我的OnReward消息不再从我的自定义插件调用.
在我的rewardcenter.cs类中,我调用插件类将侦听器设置为此脚本附加到的gameObject(在此示例中为它GameObject):
public class rewardcenter : MonoBehaviour {
int counter = 0;
void Start () {
OnReward("85");
}
// Update is called once per frame
void Update ()
{
if (counter == 20) {
#if UNITY_ANDROID
PluginClass.SetRewardListener(gameObject.name);
Debug.Log("Adding Android Reward Listener: " + gameObject.name);
#endif
}
counter++;
}
void OnReward(string quantity)
{
Debug.Log("OnReward: " + quantity);
}
}
在PluginClass.cs文件中,您可以看到我如何调用setUnityObjectNamejava插件类上的调用来将unity对象设置为传入的GameObject的名称字符串GameObject:
private static AndroidJavaObject pluginClassInstance = null;
private static AndroidJavaObject activityContext = null;

我正在尝试关注Google的活动识别示例.
在示例中,当您单击按钮时,它们会启动活动识别,但是我想在应用程序启动时启动它 - 所以我尝试将它放在onConnected方法中.但是,它最终会抛出空指针异常.
这是我如何称呼它:
@Override
public void onConnected(Bundle connectionHint) {
Log.d(TAG, "onConnected");
try {
ActivityRecognition.ActivityRecognitionApi.requestActivityUpdates(
mGoogleApiClient,
UPDATE_INTERVAL_IN_MILLISECONDS,
getActivityDetectionPendingIntent()
).setResultCallback(this);
} catch (SecurityException securityException) {
logSecurityException(securityException);
}
}
