Android GCM getToken()发送java.io.IOException:超时

添加到模块build.gradle的依赖项:
- 应用插件:“com.google.gms.googleservices”
- 编译'com.google.android.gms:play services gcm:7.5.+'
- classpath'com.google.gms:googleservices:1.3.0-beta1'
getString(R.ID.gcm\u defaultSenderId)
一旦我这样做了,我开始收到一条不同的错误消息SERVICE\u NOT\u AVAILABLE
有几个问题可以解决这个问题,但帮助我的是
我关闭了WiFi并在手机上使用了4G连接,它与gcm\U defaultSenderId和我自己的发件人ID一起工作。我遇到了这个问题,重试后得到了修复 注册前,您必须检查google api是否可用于此代码片段或类似代码:
GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance();
int resultCode = apiAvailability.isGooglePlayServicesAvailable(a);
if (resultCode == ConnectionResult.SUCCESS) { //Do the getTokencall } else { //check the code }
您可能没有收到SUCCESS resultCode。例如,如果有一个挂起的google api更新。在注册之前,播放服务可能不可用,此类可能会帮助您:
public class PlayServicesValidator {
private static final String TAG = PlayServicesValidator.class.getSimpleName();
private static final int PLAY_SERVICES_RESOLUTION_REQUEST = 9000;
/**
* Check the device to make sure it has the Google Play Services APK. If
* it doesn't, display a dialog that allows users to download the APK from
* the Google Play Store or enable it in the device's system settings.
*/
public static boolean areAvailable(Context context) {
GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance();
int resultCode = apiAvailability.isGooglePlayServicesAvailable(context);
if (resultCode != ConnectionResult.SUCCESS) {
return false;
}
return true;
}
/**
* Only call if areAvailable was previously called and returned false
* @param activity
* @return
*/
public static boolean areRecoverable(Activity activity) {
GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance();
int resultCode = apiAvailability.isGooglePlayServicesAvailable(activity);
if (resultCode != ConnectionResult.SUCCESS) {
if (apiAvailability.isUserResolvableError(resultCode)) {
return true;
} else {
return false;
}
}
return true;
}
/**
* Shows to the user a dialog to update play services
* @param activity
*/
public static void recover(Activity activity) {
GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance();
int resultCode = apiAvailability.isGooglePlayServicesAvailable(activity);
if (resultCode != ConnectionResult.SUCCESS) {
if (apiAvailability.isUserResolvableError(resultCode)) {
apiAvailability.getErrorDialog(activity, resultCode, PLAY_SERVICES_RESOLUTION_REQUEST).show();
}
}
}
}
您不需要在清单中使用INTERNET权限吗?我从一开始就拥有它,但在编辑清单时忘记添加它。我更新了声明,这可能是您的网络(可能是防火墙?)的问题,但查看整个堆栈跟踪会有所帮助。
