接收推送通知到图书馆项目 [英] Receive Push Notifications into library project
问题描述
我有一个项目作为库可以导出到我的项目的精简版. 在图书馆项目中，我实现了推送通知.我已将图书馆项目作为普通项目运行，并且推送通知工作正常. 当我将该项目作为精简版项目中的库导入时，会发生我的问题.推送通知失败.
I have one project as a library to export to lite version of my project. In the library project, I have implemented push notifications. I've runthe library project as a normal project and the push notification work fine. My problem happens when i am importing this project as a library in lite version project.The push notification failed.
这是我的GCMIntentService类:
Here is my GCMIntentService class:
public class GCMIntentService extends GCMBaseIntentService {
public static final String SENDER_ID = "206703456431";
public GCMIntentService() {
super(SENDER_ID);
}
private static final String TAG = "===GCMIntentService===";
@Override
protected void onRegistered(Context arg0, String registrationId) {
Log.i(TAG, "Device registered: regId = " + registrationId);
Applications app = (Applications) getApplication();
app.setDeviceToken(registrationId);
}
@Override
protected void onUnregistered(Context arg0, String arg1) {
Log.i(TAG, "unregistered = " + arg1);
}
@Override
protected void onMessage(Context arg0, Intent arg1) {
Log.i(TAG, "Received message. Extras: " + arg1.getExtras());
String message = arg1.getExtras().getString("message");
displayMessage(arg0, message);
// notifies user
generateNotification(arg0, message);
}
@Override
protected void onError(Context arg0, String errorId) {
Log.i(TAG, "Received error: " + errorId);
}
@Override
protected boolean onRecoverableError(Context context, String errorId) {
return super.onRecoverableError(context, errorId);
}
/**
* Issues a notification to inform the user that server has sent a message.

@SuppressWarnings("deprecation")
private static void generateNotification(Context context, String message) {
int icon = R.drawable.icon_57x57_fixed;
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification();
notification.defaults |= Notification.DEFAULT_SOUND;
notification.icon = icon;
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context,
HomeScreenActivity.class);
Intent notificationIntentV2 = new Intent(context,
LoginActivity.class);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
notification.flags = Notification.FLAG_AUTO_CANCEL;
PendingIntent intent = PendingIntent.getActivity(context, 0,
notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notificationManager.notify(0, notification);
}
class ForegroundCheckTask extends AsyncTask<Context, Void, Boolean> {
@Override
protected Boolean doInBackground(Context... params) {
final Context context = params[0].getApplicationContext();
return isAppOnForeground(context);
}
private boolean isAppOnForeground(Context context) {
ActivityManager activityManager = (ActivityManager) context
.getSystemService(Context.ACTIVITY_SERVICE);
List<RunningAppProcessInfo> appProcesses = activityManager
.getRunningAppProcesses();
if (appProcesses == null) {
return false;
}
final String packageName = context.getPackageName();
for (RunningAppProcessInfo appProcess : appProcesses) {
if (appProcess.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND
&& appProcess.processName.equals(packageName)) {
return true;
}
}
return false;
}
}
库项目中的Manifest.xml:
The Manifest.xml in library project:
<uses-permission android:name="com.myapp.libraryproject.permission.C2D_MESSAGE" />
<receiver
android:name="com.google.android.gcm.GCMBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="com.myapp.libraryproject" />
</intent-filter>
</receiver>
<service android:name="com.myapp.libraryproject.GCMIntentService" />
export Lite项目中的Manifest.xml(使用库项目作为库):
The Manifest.xml in export Lite project (use library project as library):
<uses-permission android:name="com.myapp.liteversion.permission.C2D_MESSAGE" />
<receiver
android:name="com.google.android.gcm.GCMBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="com.myapp.liteversion" />
</intent-filter>
</receiver>
<service android:name="com.myapp.libraryproject.GCMIntentService" />
推荐答案
您的问题是，默认情况下，com.google.android.gcm.GCMBroadcastReceiver假定GCMIntentService的位置位于应用程序的主程序包中，在您的情况下， com.myapp.liteversion.这就是为什么它找不到实际上在com.myapp.libraryproject.GCMIntentService中的GCMIntentService类的原因.
Your problem is that com.google.android.gcm.GCMBroadcastReceiver assumes, by default, that the location of GCMIntentService is in the main package of your app, which in your case is com.myapp.liteversion. That's why it doesn't find the GCMIntentService class, which is actually in com.myapp.libraryproject.GCMIntentService.
解决方案是创建GCMBroadcastReceiver的子类(并在清单中而不是基类中使用它)，并在其中重写以下方法:
The solution is to create a sub-class of GCMBroadcastReceiver (and use it in the manifest instead of the base class) and in it to override the following method :
protected String getGCMIntentServiceClassName(Context context) {
return getDefaultIntentServiceClassName(context);
}
类似:
protected String getGCMIntentServiceClassName(Context context) {
return GCMIntentService.class.getName();
}
