GCM: why my application crash in GCMRegistrar.checkDevice(this);
提问by alfo888_ibg
I have a simple application with a few lines because I am trying to figure out why my real application crashes in GCMRegistrar.checkDevice(this) (if I delete it my application doesn't crash). Can anyone help? :( :
我有一个包含几行的简单应用程序，因为我想弄清楚为什么我的真实应用程序在 GCMRegistrar.checkDevice(this) 中崩溃（如果我删除它，我的应用程序不会崩溃）。任何人都可以帮忙吗？:( :
public class DemoActivity extends Activity {
private String TAG = "** pushAndroidActivity **";
private TextView mDisplay;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
setContentView(R.layout.main);
mDisplay = (TextView) findViewById(R.id.display);
mDisplay.setText("ciao");

It's probably running on a device that doesn't support GCM, so your call to GCMRegistrar.checkDevice( this );is throwing an exception. Check your logcat to be sure.
它可能在不支持 GCM 的设备上运行，因此您的调用会GCMRegistrar.checkDevice( this );引发异常。检查您的 logcat 以确保。
If you're testing it on an emulator, make sure you have the emulator set up to use Google APIs. When you create the emulator, the create new AVD window has a "Target" box. Select something in that box that says "Google APIs".
如果您在模拟器上测试它，请确保您已将模拟器设置为使用 Google API。创建模拟器时，创建新 AVD 窗口有一个“目标”框。在该框中选择显示“Google API”的内容。

Plz Follow the Following Steps
请按照以下步骤操作
1. Include "gcm.jar"in libs in your Application
1. 在您的应用程序的库中包含“gcm.jar”
2. Android SDK Manager => Extras => Install Google Cloud Messaging for Android Library (Obsolete)
2. Android SDK Manager => Extras => 为 Android 库安装 Google Cloud Messaging（已过时）
3. Android SDK Manager => Android 4.3 (API 18) => Install Google APIs
3. Android SDK 管理器 => Android 4.3 (API 18) => 安装 Google API

In eclipse
在日食
1)Download gcm.jar
1)下载gcm.jar
2)buildpath-->configure build path-->libraries-->external jar -->path_to_gcmjar
2)buildpath-->configure build path-->libraries-->external jar-->path_to_gcmjar
this is the most important point
这是最重要的一点
3)copy gcm.jar and paste in lib folder of project
3）复制gcm.jar并粘贴到项目的lib文件夹中
