我在尝试注册 GCM 时收到此错误。我的 AVD 目标是 Android 4.2.2，API 级别是 17。使用 SGS3 4.2.2 工作正常，Galaxy GT-I9003 和所有版本的模拟器都不起作用。我已经在正确的文件夹中导入了所有库。如果有人可以帮助我们，请写出解决方案！

我的代码是：
try {
if (gcm == null) {
gcm = GoogleCloudMessaging.getInstance(context);
}
while (regid.equals("")) {
regid = gcm.register(SENDER_ID); //STOP HERE AND CALL EXCEPTION
msg = "Device registered, registration id=" + regid;
setRegistrationId(context, regid);
}
Controller.setDeviceToken(regid);
} catch (IOException ex) {
ex.printStackTrace();
msg = "Error :" + ex.getMessage();
}
