Android google云消息示例不工作 [英] Android google cloud messaging sample not working
问题描述
按照此处的教程 http://developer.android.com/google/gcm /gs.html ，以便设置GCM。
当前正在尝试注册设备的过程。
然而，由于某种原因，应用程序总是似乎崩溃
gcm = GoogleCloudMessaging.getInstance（this）;
Im following the tutorial here http://developer.android.com/google/gcm/gs.html in order to setup GCM. Im currently in the process of trying to register the device. However, for some reason, the application always seems to crash at gcm = GoogleCloudMessaging.getInstance(this);
stacktrace似乎指向以下内容：
06-18 13：42：20.909：I / dalvikvm（11613）：找不到方法com。 google.android.gms.gcm.GoogleCloudMessaging.getInstance，从方法pushNotification.PushNotification $ 1.run引用
The stacktrace seems to point at the following: 06-18 13:42:20.909: I/dalvikvm(11613): Could not find method com.google.android.gms.gcm.GoogleCloudMessaging.getInstance, referenced from method pushNotification.PushNotification$1.run
到目前为止的示例
public PushNotification(Context c, Activity activity)
{
context = c;
this.activity = activity;
regid = getRegistrationId(context);
if (regid.length() == 0) {
Log.d("IN PUSHNOTIFICATION ","NOT REGISTERED. REGISTERING NOW.....");
registerBackground();
}
Log.d("IN PUSHNOTIFICATION ","REGISTRATION COMPLETE.....");
Log.d("IN PUSHNOTIFICATION ","REGISTRATION ID IS: " + regid);
gcm = GoogleCloudMessaging.getInstance(activity); //never reaches this code
}
private void registerBackground() {
Thread thread = new Thread(new Runnable()
{
public void run()
{
String msg = "";
try {
if (gcm == null) {
Log.d("IN PUSHNOTIFICATION", "IN BACKGROUND. gcm == NULL");
gcm = GoogleCloudMessaging.getInstance(context);
Log.d("IN PUSHNOTIFICATION", "IN BACKGROUND. AFTER gcm.GETINSTANCE");
}
Log.d("IN PUSHNOTIFICATION", "IN BACKGROUND. BEFORE gcm.register");
regid = gcm.register(SENDER_ID);
msg = "Device registered, registration id=" + regid;
Log.d("IN PUSHNOTIFICATION", "IN BACKGROUND. regid == " + regid);
// You should send the registration ID to your server over HTTP,
// so it can use GCM/HTTP or CCS to send messages to your app.
// For this demo: we don't need to send it because the device
// will send upstream messages to a server that echo back the message
// using the 'from' address in the message.
// Save the regid - no need to register again.
setRegistrationId(context, regid);
} catch (IOException ex) {
Log.d("IN PUSHNOTIFICATION", "IN BACKGROUND. EXCEPTION ERROR ERROR: ex = " + ex.getMessage());
msg = "Error :" + ex.getMessage();
}
}
}
);
thread.start();
}
这里是完整的stacktrace

推荐答案
我解决了这个问题。
虽然我链接到google-play-services_lib项目，我还必须将jar文件google-play-services_lib.jar添加到项目中。
I solved the problem. Although I was linking to google-play-services_lib project, I also had to add the jar file, google-play-services_lib.jar into the project.
