我正在处理FCM推送通知。直到Android O更低版本都可以正常工作。我已经查看了Android Docs，并在推送通知中也做了Channels，但是问题是我的CustomPushReceiver中没有推送信息。对于较低的版本，它工作得很好。我的自定义推送接收器以及清单代码如下：
public class CustomPushReceiver extends ParsePushBroadcastReceiver {
int importance = NotificationManager.IMPORTANCE_HIGH;
private SharedPreferences prefs ;
Boolean languageBoolean = true;
public CustomPushReceiver() {
super();
Log.e("CustomPushReceiver","Come to this portion");
}
@Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
Log.e("onReceive","Come to this portion");
}
@Override
public void onPushReceive(Context context, Intent intent) {
Log.e("onPushReceive","Come to this portion");
if (intent == null)
return;
try {
String action = intent.getAction();
JSONObject json = new JSONObject(intent.getExtras().getString("com.parse.Data"));
if (action.equalsIgnoreCase("com.parse.push.intent.RECEIVE")) {
if (json.has("alert"))
{
String message = json.getString("alert");
localPushNotifications26GreaterAPI(context, message, json);
}
}
} catch (JSONException e) {
}
}
@Override
protected void onPushDismiss(Context context, Intent intent) {
super.onPushDismiss(context, intent);
Log.e("onPushDismiss","Come to this portion");
}
@Override
protected void onPushOpen(Context context, Intent intent) {
super.onPushOpen(context, intent);
Log.e("onPushOpen","Come to this portion");
}
public void localPushNotifications26GreaterAPI(Context context, String message, JSONObject jsonObject){
Log.e("localPushNoti26API","Come to this portion");
try {
if (ParseUser.getCurrentUser() != null) {
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
Intent intent = new Intent(context, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
// The id of the channel.
String id = "my_channel_01";
CharSequence name = "com.dcas.responder";
String description = "Description";
NotificationChannel mChannel = new NotificationChannel(id, name, importance);
mChannel.setDescription(description);
mChannel.enableLights(true);
mChannel.setLightColor(Color.RED);
mChannel.enableVibration(true);
mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
mNotificationManager.createNotificationChannel(mChannel);
mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
int notifyID = 1;
String CHANNEL_ID = "my_channel_01";
String contentTitle = "", contentText ="", messageText ="";
if (languageBoolean == true) {
contentTitle = "Dubai Corporation Ambulance Services";
contentText = "Emergency Request";
messageText = message;
}else{
contentTitle = context.getString(R.string.dubai_corporation_for_ambulance_services);
contentText = context.getString(R.string.emergency_request);
messageText = context.getString(R.string.press_here_to_get_medical_help_in_minutes);
}
Notification notification = new Notification.Builder(context, CHANNEL_ID)
.setContentTitle(contentTitle)
.setContentText(contentText)
.setStyle(new Notification.BigTextStyle().bigText(messageText))
.setContentIntent(contentIntent)
.setSmallIcon(R.drawable.push_icon)
.setChannelId(CHANNEL_ID)
.build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
mNotificationManager.notify(notifyID, notification);
} else {
localPushNotifications26LowerAPI(context , message);
}
}
}catch(Exception exp){
exp.getMessage();
}
}
public void localPushNotifications26LowerAPI(Context context, String message){
Log.e("localPushNotiLowAPI","Come to this portion");
if (ParseUser.getCurrentUser() != null) {
Intent intent = new Intent(context, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder b = new NotificationCompat.Builder(context);
String contentTitle = "", contentText ="", messageText ="";
if (languageBoolean == true) {
contentTitle = "Dubai Corporation Ambulance Services";
contentText = "Emergency Request";
messageText = message;
}else{
contentTitle = context.getString(R.string.dubai_corporation_for_ambulance_services);
contentText = context.getString(R.string.emergency_request);
messageText = context.getString(R.string.press_here_to_get_medical_help_in_minutes);
}
b.setAutoCancel(true)
.setDefaults(Notification.DEFAULT_ALL)
.setWhen(System.currentTimeMillis())
.setSmallIcon(R.drawable.push_icon)
.setTicker(contentText)
.setContentTitle(contentTitle)
.setContentText(messageText)
.setContentIntent(contentIntent)
.setDefaults(Notification.DEFAULT_LIGHTS | Notification.DEFAULT_SOUND)
.setContentIntent(contentIntent)
.setContentInfo("Info");
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(1, b.build());
}
}
}
我的清单文件中，我声明了我的FCM设置和CustomPushReceiver：
<receiver
android:name="receivers.CustomPushReceiver"
android:exported="false">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.USER_PRESENT" />
<action android:name="com.parse.push.intent.RECEIVE" />
<action android:name="com.parse.push.intent.DELETE" />
<action android:name="com.parse.push.intent.OPEN" />
</intent-filter>
</receiver>
<receiver
android:name="com.parse.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.dcas.responder" />
</intent-filter>
</receiver>
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
<meta-data android:name="com.parse.push.gcm_sender_id"
android:value="id:5562400#####" />
我要初始化和订阅解析推送通道的Application类：
ParseInstallation installation = ParseInstallation.getCurrentInstallation();
installation.put("GCMSenderId", "5562400#####");
installation.saveInBackground();
ParsePush.subscribeInBackground("dcas" + ParseUser.getCurrentUser().getObjectId(), new SaveCallback() {
@Override
public void done(ParseException e) {
if(e==null){
Intent intent = new Intent(SplashScreenActivity.this, MainActivity.class);
startActivity(intent);
finish();
}
}
});
这在Android 27较低版本上可以很好地运行，而且仅在某些时候它也可以在Android 27版本上运行，这很奇怪，没有任何理由。
