Question

GCM始终使用以下代码返回SENDER_INVALID ..

我所能找到的只是项目ID有效，这是有效的，我也尝试过更改项目，但这没有帮助。

我还尝试了整个stackoverflow和google群组，也改变了谷歌帐户，并尝试使用旧的和新的Google API控制台创建应用程序。

public class GCM {
    private static final String TAG = "GCM";
    public static final String EXTRA_MESSAGE = "message";
    public static final String PROPERTY_REG_ID = "registration_id";

    String regid;
    public GCM(Context ctx, Activity act){
        mContext=ctx;
        mActivity=act;
        gcm = GoogleCloudMessaging.getInstance(ctx);
    }
    public String getRegistrationId(Context context) {
        final SharedPreferences prefs = context.getSharedPreferences("DealsGeo_GCM", Context.MODE_PRIVATE);
        String registrationId = prefs.getString(PROPERTY_REG_ID, PROPERTY_REG_ID);
        if (registrationId.isEmpty()) {
            Log.i(TAG, "Registration not found.");
            return "";
        }

您有一个类似https://code.google.com/apis/console/?noredirect#project的网址： 581054524740 ：在您的项目谷歌控制台中访问，因此您必须输入发件人代码：581054524740

Answer 2

也许您在复制Google API项目ID时忘记了一个数字。您的项目ID - 44843754432 - 有11位数，而我看到的所有项目ID都有12位数。
