使用我的代码就像魅力一样工作：
向特定用户发送通知并管理通知的点击。
implementation 'com.google.firebase:firebase-messaging:20.1.3'
implementation 'com.google.firebase:firebase-analytics:17.2.3'
清单
<meta-data
android:name="com.google.firebase.messaging.default_notification_channel_id"
android:value="default_channel_id" />
<service
android:name=".FCMService" >
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
活动
1. project setting > cloud messaging > server key
AUTH_KEY = server key
2. token id of a particular device is
String device_token = FirebaseInstanceId.getInstance().getToken();
发送通知时
new Thread(new Runnable() {
@Override
public void run() {
pushNotification(senderName + " : " + message);
}
}).start();
private void pushNotification(String message) {
JSONObject jPayload = new JSONObject();
JSONObject jNotification = new JSONObject();
JSONObject jData = new JSONObject();
try {
// notification can not put when app is in background
jNotification.put("title", getString(R.string.app_name));

jNotification.put("badge", "1");

// jData.put("picture", "https://miro.medium.com/max/1400/1*QyVPcBbT_jENl8TGblk52w.png");
//to token of any deivce
jPayload.put("to", device_token);
// data can put when app is in background
jData.put("goto_which", "chatactivity");
jData.put("user_id", mCurrentUserId);
jPayload.put("priority", "high");
jPayload.put("notification", jNotification);
jPayload.put("data", jData);
URL url = new URL("https://fcm.googleapis.com/fcm/send");

conn.setDoOutput(true);
// Send FCM message content.
OutputStream outputStream = conn.getOutputStream();
outputStream.write(jPayload.toString().getBytes());
// Read FCM response.
InputStream inputStream = conn.getInputStream();
final String resp = convertStreamToString(inputStream);

管理点击通知：
它调用启动器活动，因此您可以在启动器活动中管理特定活动的调用
您的启动器活动看起来像
if (getIntent().getExtras() != null) {
String goto_which = getIntent().getStringExtra("goto_which");
String chatUser = getIntent().getStringExtra("user_id");
if (goto_which.equals("chatactivity")) {
Intent chatIntent = new Intent(getBaseContext(), ChatActivity.class);
chatIntent.putExtra("user_id", chatUser);
startActivity(chatIntent);
} else if (goto_which.equals("grpchatactivity")) {
Intent chatIntent = new Intent(getBaseContext(), GroupChatActivity.class);
chatIntent.putExtra("group_id", chatUser);
startActivity(chatIntent);
}
}
