如何解决引起原因：libcore.io.ErrnoException：recvfrom失败：ECONNRESET由对等方重置连接和sendto失败：EPIPE断开的管道
请不要将其标记为重复
你好 我正在创建一个Android应用，以从Google日历获取事件。我的设备没有Google Play服务，这是设备Philips 10bdl3051t / 02和Android版本4.4.4。 我已经通过App Auth从浏览器授权了用户，我已经获得了授权令牌并能够获取事件。该令牌在大约一小时内保持有效，然后需要刷新。 我正在使用以下代码刷新令牌。问题在于，有时它没有刷新的令牌并抛出此异常。
原因：libcore.io.ErrnoException：recvfrom失败：ECONNRESET（对等方重置连接）
原因：libcore.io.ErrnoException：sendto失败：EPIPE（管道损坏）
代码段以刷新令牌
private void checkGoogleCalendarRESTApiAuthToken() {
SharedPreferences settings = getSharedPreferences(PREFS_FILE,0);
SharedPreferences.Editor editor = settings.edit();
// only refresh the token when it is about to expire
long timeDifference = settings.getLong("googleCalendarRESTApiAccessTokenExpiry",new Date().getTime()) - new Date().getTime();
Log.d("authtoken"," googleCalendarRESTApiAccessTokenExpiry : " + String.valueOf(settings.getLong("googleCalendarRESTApiAccessTokenExpiry",new Date().getTime())));
Log.d("authtoken"," timeDifference: " + String.valueOf(timeDifference));
if (timeDifference < 20) {
Thread tokenRefreshTask = new Thread(){
@Override
public void run() {
Log.d("authtoken"," tokenRefreshTask: " );
mAuthState.performActionWithFreshTokens(new AuthorizationService(context),new AuthState.AuthStateAction() {
@Override
public void execute(@Nullable String accessToken,@Nullable String idToken,@Nullable AuthorizationException exception) {
Log.d("authtoken"," performActionWithFreshTokens: " );
editor.putString("googleCalendarRESTApiAccessToken",mAuthState.getAccessToken());
editor.putLong("googleCalendarRESTApiAccessTokenExpiry",mAuthState.getAccessTokenExpirationTime());
editor.apply();
HttpTransport transport = AndroidHttp.newCompatibleTransport();
JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
GoogleCredential googleAccountCredential = new GoogleCredential().setAccessToken(mAuthState.getAccessToken());
GoogleService = new com.google.api.services.calendar.Calendar.Builder(transport,jsonFactory,googleAccountCredential).build();
Log.d("authtoken"," getNeedsTokenRefresh: " + String.valueOf(mAuthState.getNeedsTokenRefresh()));
Log.d("authtoken"," getAccessTokenExpirationTime: " + String.valueOf(mAuthState.getAccessTokenExpirationTime()));
Log.d("authtoken"," getAccessToken: " + String.valueOf(mAuthState.getAccessToken()));
Log.d("authtoken"," isAuthorized: " + String.valueOf(mAuthState.isAuthorized()));
Log.d("authtoken"," getLastTokenResponse: " + String.valueOf(mAuthState.getLastTokenResponse()));
Log.d("authtoken"," getRefreshToken: " + String.valueOf(mAuthState.getRefreshToken()));
Log.d("authtoken"," getLastAuthorizationResponse: " + String.valueOf(mAuthState.getLastAuthorizationResponse()));
}
});
}
};tokenRefreshTask.start();
}
}
此设备具有通过此代码控制的侧面LED，此代码每20秒运行一次，以使LED状态与日历事件保持同步。可能是这段代码造成了问题，如果发现任何问题，请提出修改建议。
