我有这个奇怪的错误 - 当我登录(有网络连接)然后我禁用网络然后当我尝试syncOne()
我得到:
10-09 16:47:22.986 23444-23444/package.app.whatever E/asd-local-error: java.net.UnknownHostException: Unable to resolve host "cbm.aype.pl": No address associated with hostname/libcore.io.GaiException: getaddrinfo failed: EAI_NODATA (No address associated with hostname)/java.net.UnknownHostException: Unable to resolve host "myhost.com": No address associated with hostname

我读到Retrofit会抛出IOException
而没有可用的网络连接,但我不知道如何抓住它。这是正确的代码:
private void syncOne(){
RealmResults<CallLog> res = Realm.getDefaultInstance()
.where(CallLog.class)
.equalTo(Constants.EXTRA_CALL_LOG_PRIVATE, false)
.equalTo(Constants.EXTRA_CALL_LOG_DEFAULT_SYNC, true)
.greaterThan(Constants.EXTRA_CALL_LOG_DATE_EDIT, Utils.getUTCToDate(lastSuccessfulSync))
.findAll();
listCallLogs.addAll(res);
String json = jsonCallLogAdapter.toJson(listCallLogs);
Log.d("asd-1json1", json);
Subscription sendLogs = networkClient
.sendCallLogs(token, RequestBody.create(MediaType.parse("application/json"), json))
.flatMap(response -> {
return networkClient.getCallLogsAfterDate(token, lastSuccessfulSync);
})
.flatMap(response ->{
String json2 = "";
try {
json2 = response.body().string();
listCallLogs.clear();
listCallLogs = jsonCallLogAdapter.fromJson(json2);
Log.d("asd-1json2", json2);
} catch (IOException e){
Log.e("IOException", e.toString());
}
RealmResults<Contact> res3 = Realm.getDefaultInstance()
.where(Contact.class)
.equalTo(Constants.EXTRA_CONTACT_PRIVATE, false)
.greaterThan(Constants.EXTRA_CONTACT_DATE_EDIT, Utils.getUTCToDate(lastSuccessfulSync))
.findAll();
listContacts.clear();
listContacts.addAll(res3);
String json3 = jsonContactAdapter.toJson(listContacts);
Log.i("asd-1json3", json3);
return networkClient.sendContacts(token, (RequestBody.create(MediaType.parse("application/json"), json3)));
})
.flatMap(response -> {
return networkClient.getContactsAfterDate(token, lastSuccessfulSync);
})
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(
response -> {
stopRefreshing(swipeRefreshLayout);
if(response.isSuccessful()){
try {
Log.d("asd-1json4", response.body().string());
SharedPreferences.Editor editor = userdata.edit();
editor.putString(Constants.EXTRA_LAST_SYNC, Utils.getDateInUTC(Calendar.getInstance().getTime()));
editor.commit();
Toast.makeText(c,
c.getResources().getString(R.string.synchronization_database_synced),
Toast.LENGTH_SHORT).show();
} catch (IOException e){
Log.d("asd-sync-one-error", e.toString());
}
} else {
try{
String s = response.errorBody().string();
Log.e("asd-server-error", s);
Toast.makeText(c,
c.getResources().getString(R.string.synchronization_error_sending_logs_server),
Toast.LENGTH_SHORT).show();
} catch (IOException e){
e.printStackTrace();
}
}
},
error -> {
if(error instanceof IOException){
}
stopRefreshing(swipeRefreshLayout);
Toast.makeText(c,
c.getResources().getString(R.string.synchronization_error_sending_logs_local),
Toast.LENGTH_SHORT).show();
Log.e("asd-local-error", error.toString()
+ "/" + error.getCause()
+ "/" + error);
Crashlytics.logException(error);
});
}
答案 0 :(得分:1)
不知道这个错误是怎么发生的,但我有一个预防性解决方案。
private boolean isNetworkAvailable() {
ConnectivityManager connectivityManager
= (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}
现在当你像这样调用syn检查时
if(isNetworkAvailable()){
doSync()
}
在你的清单中添加一项权限
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
希望最好!
