以下参数是什么:
alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
AlarmManager.INTERVAL_FIFTEEN_MINUTES, alarmIntent);
以下内容:
alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, alarmIntent);
有什么区别,两者在功能方面有何不同？
让我从我想要的开始:
我想制作一个应用程序part native and part webviews.
问题 - 维护本机和Webview部件之间的会话.
我处理这个的方法:
我打算实现一个本机登录,在其中我向用户提供两个EditTextboxes和一个按钮,用户输入凭据,我将它们作为JSON发布到服务器.
服务器响应成功或错误.基于Success标志,我读取了此连接的标头值并解压缩SessionCookie:
switch (responseCode) {
case 200:
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String inputLine;
response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
//IF SUCCESS
Map<String, List<String>> map = conn.getHeaderFields();
for (Map.Entry<String, List<String>> entry : map.entrySet()) {
System.out.println("Key : " + entry.getKey() + " ,Value : " + entry.getValue());
}
SSID = map.get("Set-Cookie").toString();
SSID = SSID.substring(1,SSID.length()-1);
return response.toString(); …当我尝试在pre API 21设备上运行我的应用程序时,我收到了这个奇怪的错误:

PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();
cm.setMaxTotal(60);
cm.setDefaultMaxPerRoute(60);
CloseableHttpClient httpclient = HttpClients.custom().setConnectionManager(cm).build();
HttpPost httpPost = new HttpPost(url);
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-type", "application/json");
CloseableHttpResponse response = null;
现在我有一个执行器服务，负责调用实际的发布，我将上述参数交给执行器服务，如下所示：
executor.execute(new LocalThreadPoolExecutor(line, client, httpPost,response ));
line 是我尝试发送的 JSON 有效负载。
现在我在执行程序服务中的方法如下所示：
private void postData(String data, CloseableHttpClient client, HttpPost httpPost,
CloseableHttpResponse response) throws Exception {
System.out.println("Post hit");
StringEntity entity = new StringEntity(data);
httpPost.setEntity(entity);
response = client.execute(httpPost);

git branch "feature/BA-302-[AU]Intl-BCard"
但是我得到：

不确定，我缺少什么
另外为了澄清，我已经尝试过：
git checkout -b feature/BA-302-[AU]Intl-BCard
结果如下：
zsh：未找到匹配项：feature/BA-302-[AU]Intl-BCard

我从这里开始关注战略模式的一个例子
教程中的所有内容都很清楚但是:
public class Context {
private Strategy strategy;
public Context(Strategy strategy){
this.strategy = strategy;
}
public int executeStrategy(int num1, int num2){
return strategy.doOperation(num1, num2);
}
}
因此Context类在其构造函数中需要一个Strategy参数.
战略的定义是:
public interface Strategy {
public int doOperation(int num1, int num2);
}
上面是一个接口,Context Class需要一个Strategy类型的对象.在StrategyPatternDemo类中,我们执行以下操作:
public class StrategyPatternDemo {
public static void main(String[] args) {
Context context = new Context(new OperationAdd());
System.out.println("10 + 5 = " + context.executeStrategy(10, 5));
context = new Context(new OperationSubstract());
System.out.println("10 - 5 = " + context.executeStrategy(10, …
