使用IMEI作为JSON服务参数 [英] Using IMEI as a parameter for JSON Service
本文介绍了使用IMEI作为JSON服务参数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
抓的AsyncTask后，我遇到了另一个颠簸的道路。使用JSON（它连接到我的本地SQLServer的，我想检索使用的IMEI作为字符串参数的对象。我已经设置断点以我的AsyncTask调用，它只是崩溃，甚至没有走过，每个手机的IMEI是存储在我的数据库。
我实现我的设备上运行它的希望以下AsyncTask的，而不是在模拟器。
我怀疑这可能与我的设备，既是我的网络服务是我的电脑上运行。我也改变了代理和端口在我的APN设置为我服务的URI一致，但它仍然没有回应，甚至。
TelephonyManager telephonyManager =（TelephonyManager）this.getSystemService（Context.TELEPHONY_SERVICE）;
IMEI = telephonyManager.getDeviceId（）;
新loadDevice（）执行（IMEI）;
这是从我的onCreate方法的code片段。
下面是AsyncTask的类：
//的AsyncTask从设备加载GET ManifestID

} }
我的其他AsyncTasks都工作正常。不过，我把这个野兽作为第一个AsyncTask的运行后，其他均未击中。

解决方案
可能是这2个事情之一：
- 添加的权限来体现
＆LT;使用许可权的android：NAME =android.permission.READ_PHONE_STATE>（删除后的空间'＆LT;'） - 您可以宣布在MainActivity布局文件中的按钮，但将它转换为微调，同时启动按钮，反之亦然。
after grasping AsyncTask, I have run into yet another road bump. Using JSON (which connects to my local SQLServer, I would like to retrieve an object using the IMEI as a string parameter. I have set a breakpoint to my AsyncTask call and it just crashes, without even walking through. The IMEI of each mobile is stored in my database.
I implementing the following AsyncTask with the hope of running it on my device, and not on an emulator.
I suspect that it may have to do with my device, as both my web services are running on my PC. I have also changed the proxy and port in my APN settings to coincide with the URI of my service but it still doesn't even respond.
TelephonyManager telephonyManager = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
IMEI = telephonyManager.getDeviceId();
new loadDevice().execute(IMEI);
This is the code snippet from my OnCreate method.
Here is the AsyncTask class:
//AsyncTask to load get ManifestID from Device
public class loadDevice extends AsyncTask<String, String, Manifests>
{
private ProgressDialog progressDialog = new ProgressDialog(MainActivity.this);
InputStream inputStream = null;
String theString = "";
StringBuilder builder;
protected void onPreExecute()
{
progressDialog.setMessage("Getting your assigned Manifest...");
progressDialog.show();
progressDialog.setOnCancelListener(new OnCancelListener()
{
public void onCancel(DialogInterface arg0)
{
loadDevice.this.cancel(true);
}
});
}
@Override
protected Manifests doInBackground(String... arg0)
{
try
{
//http get request
HttpGet request = new HttpGet(CentralURI + "/loadDevice/" + IMEI);
//set the hedear to get the data in JSON format
request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");
DefaultHttpClient client = new DefaultHttpClient();
//get the response
HttpResponse response = client.execute(request);
HttpEntity entity = response.getEntity();
//read content
InputStream is = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
builder = new StringBuilder();
String line;
while ((line = reader.readLine()) != null)
{
builder.append(line);
}
is.close();
theString = builder.toString();
JSONObject manifestJSON = new JSONObject(theString);
JSONArray manifest = manifestJSON.getJSONArray("loadDeviceResult");
for(int i = 1; i < manifest.length(); i++)
{
JSONObject manObj = manifest.getJSONObject(i);
man.ManifestID = manObj.getInt("OriginalSOGManifestID");
man.DeviceManifestID = manObj.getInt("DeviceManifestID");
man.IMEI = manObj.getString("IMEI");
man.JobType = manObj.getString("prefix");
man.RegNo = manObj.getString("RegNo");
man.Complete = manObj.getBoolean("Complete");
man.DateComplete = manObj.getString("DateComplete");
}
}
catch (Exception e)
{
e.printStackTrace();
}
return man;
}
protected void onPostExecute(Manifests manifest)
{
//Manifests manifestToGet = new Manifests();
//String manifestCode = manifestToGet.getJobType() + Integer.toString(manifestToGet.getManifestID());
//new getManifestItems().execute(manifestCode);
}
}
My other AsyncTasks were working fine. However, after I put this beast in as the first AsyncTask to run, the others were not getting hit.
Here is the AsyncTask that relies on a property that is in the object retrieved by the first AsyncTask:-
//ASyncTask to get ManifestItem from each manifest
public class getManifestItems extends AsyncTask<String, String, ArrayList<ManifestItemObj>>
{
private ProgressDialog progressDialog = new ProgressDialog(MainActivity.this);
InputStream inputStream = null;
String theString = "";
StringBuilder builder;
protected void onPreExecute()
{
progressDialog.setMessage("Loading manifests...");
progressDialog.show();
progressDialog.setOnCancelListener(new OnCancelListener()
{
public void onCancel(DialogInterface arg0)
{
getManifestItems.this.cancel(true);
}
});
}
@Override
protected ArrayList<ManifestItemObj> doInBackground(String... params)
{
Manifests assign = man;
String manifestCode = assign.getJobType() + Integer.toString(assign.getManifestID());
try
{
//http get request
HttpGet request = new HttpGet(POD_URI + "/getJobs/" + manifestCode);
//set the hedear to get the data in JSON format
request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");
DefaultHttpClient client = new DefaultHttpClient();
//get the response
HttpResponse response = client.execute(request);
HttpEntity entity = response.getEntity();
//read content
InputStream is = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
builder = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
builder.append(line);
}
is.close();
theString = builder.toString();
JSONObject jobsJSON = new JSONObject(theString);
JSONArray jobs = jobsJSON.getJSONArray("getJobsResult");
ManifestItemObj miDumb = new ManifestItemObj();
miDumb.ManifestItemID = -1;
miDumb.FKID = -1;
miDumb.JobType = "--Please Select--";
for(int i = 1; i < jobs.length(); i++)
{
JSONObject mit = jobs.getJSONObject(i);
ManifestItemObj mi = new ManifestItemObj();
mi.ManifestItemID = mit.getInt("ManifestItemID");
mi.JobType = mit.getString("JobType");
mi.FKID = mit.getInt("FKID");
//ShipTo object
JSONObject stObj = mit.getJSONObject("ShipTo");
ShipTo sto = new ShipTo();
sto.ShipToId = stObj.getInt("ShipToId");
sto.ShipToName = stObj.getString("ShipToName");
sto.ShipToAddress1 = stObj.getString("ShipToAddress1");
sto.ShipToAddress2 = stObj.getString("ShipToAddress2");
sto.ShipToCity = stObj.getString("ShipToCity");
sto.ShipToPostcode = stObj.getString("ShipToPCode");
sto.ShipToState = stObj.getString("ShipToState");
mi.shipTo = sto;
jobList.add(mi);
}
jobList.add(0, miDumb);
}
catch (Exception e)
{
e.printStackTrace();
}
return jobList;
}
protected void onPostExecute(ArrayList<ManifestItemObj> mio)
{
ManifestItemAdapter mia = new ManifestItemAdapter(MainActivity.this, android.R.layout.simple_spinner_item, jobList);
this.progressDialog.dismiss();
list_job.setAdapter(mia);
}
}
EDIT: Here is the logcat. I'm suspecting that the Button is being cast to the Spinner. Definitely not my intention but that's what it's saying:-

解决方案
Could be one of these 2 things:
- Add permission to manifest < uses-permission android:name="android.permission.READ_PHONE_STATE"> (remove space after '<')
- You could be declaring a Button in the layout file of the MainActivity but cast it as a Spinner while initiating the Button or vice-versa.
