PHP API から情報を取得して Google カレンダーから情報を取得するアプリケーションがあります。問題は、アプリがエミュレーターで動作することですが、携帯電話で使用しようとすると、情報のない通常の黒い画面しか表示されません。接続の問題のようです (私の最初の考えとは異なります)。エミュレータのAndroidバージョンは2.3.3で、私の電話でも同じです。
これは私のコードです:
public class AgendaActivity extends Activity {
/** Called when the activity is first created. */
public static final String CAL= "http://192.168.1.58/calendar.php";
ListView vue;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
vue = (ListView) findViewById(R.id.listView1);
List<HashMap<String, String>> liste = new ArrayList<HashMap<String,String>>();
HashMap<String, String> element;
String result = getServerData(CAL);
String[] chaine = result.split(";");
for(int i=1;i<chaine.length-1;i++)
{
String[] event = chaine[i].split(":");
element = new HashMap<String, String>();
element.put("titre", event[1]);
element.put("date",event[3]+":"+event[4] );
liste.add(element);
}
ListAdapter adapter = new SimpleAdapter(this,
liste,
android.R.layout.simple_list_item_2,
new String[] {"titre", "date"},
new int[] {android.R.id.text1, android.R.id.text2 });
vue.setAdapter(adapter);
}
private String getServerData(String returnString) {
InputStream is = null;
String result = "";
File file = new File("sdcard/event.txt");
FileWriter fw;
FileReader fr;
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("contact",""));
HttpResponse response=null;
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(returnString);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}catch(Exception e){
Log.e("log_tag", "Error in http connection " + e.toString());
String str = "";
int i = 0;
try {
fr =new FileReader(file);
while((i = fr.read()) != -1)
str += (char)i;
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
returnString=str;
return returnString;
}
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result=sb.toString();
}catch(Exception e){
Log.e("log_tag", "Error converting result " + e.toString());
}
try{
JSONArray jArray = new JSONArray(result);
for(int i=0;i<jArray.length();i++)
{
JSONObject json_data = jArray.getJSONObject(i);
returnString = ""+ json_data;
}
}catch(JSONException e)
{
returnString=e.toString();
}
try {
fw = new FileWriter(file);
fw.write(returnString);
fw.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return returnString; }
}
シミュレーターのアプリは正常に動作しますが、アプリを起動すると、エラー セクションで logcat が表示されます。
