Android app launches slow on notification tap

I'm using FCM to send push notifications to my app; the expected behaviour when the user taps the notification is to launch the app as normal, like tapping the launcher app icon.
At the moment, when user tap on the notification, spend more than 30 seconds before app is opened. Notification go away, but the app does not opens... Not even a white screen, nothing.
When onMessageReceived is triggered, displayNotification method is called.
private void displayNotification(String title, String body) {
createNotificationChannel();
PendingIntent contentIntent = generateNotificationContentIntent();
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, CONTENTS_CHANNEL_ID)
.setSmallIcon(R.drawable.logo_no_bg_white)
.setContentTitle(title)
.setContentText(body)
.setContentIntent(contentIntent)
.setAutoCancel(true);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(new Random().nextInt(), notificationBuilder.build());
}
private PendingIntent generateNotificationContentIntent(){
Intent intent = new Intent(this, MainActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addNextIntentWithParentStack(intent);
return stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
}
private void createNotificationChannel() {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O){
return;
}
NotificationChannel notificationChannel = new NotificationChannel(CONTENTS_CHANNEL_ID, CONTENTS_CHANNEL_ID, NotificationManager.IMPORTANCE_DEFAULT);
notificationChannel.setDescription(CONTENTS_CHANNEL_ID);
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(notificationChannel);
}
My onCreate MainActivity method simply checks wether the user is logged, and if so, launches the HomeActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
PACKAGE_NAME = getApplicationContext().getPackageName();
//Read shared preferences.
sharedPref = getSharedPreferences(PACKAGE_NAME, Context.MODE_PRIVATE);
if(sharedPref.contains("token") || sharedPref.getBoolean("isGuest", false)){
//Redirect to home
Intent homeIntent = new Intent(getApplicationContext(), HomeActivity.class );
homeIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(homeIntent);
finish();
}
loadTowns(this);
}
What am I doing wrong?

Add PendingIntent.FLAG_ONE_SHOT to your pending intent.
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT|PendingIntent.FLAG_ONE_SHOT);
Also add android:exported="true" to the activity tag in manifest

Try this, it is working for me.
Intent notificationIntent = new Intent(this, MainActivity.class);
/*flags for resume activity*/
notificationIntent.setFlags( Intent.FLAG_ACTIVITY_SINGLE_TOP
|Intent.FLAG_ACTIVITY_CLEAR_TASK
|Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(contentIntent);
/*for clear notification on click*/
builder.setAutoCancel(true);

Android background service get killed eventhough it has return START_STICKY in it

One of the requirements in the app that I am developing is "show something on the screen on event." Basically, I made a background service and in that, I catch the screen on intent and pass it to a BroadcastReceiver. Then, in the receiver, I open an activity and "show something". However, on Android 7-8. I think the background service get killed over a night because the next day my service is not catching anything and my receiver is not receiving. I even ask for the
<uses-permission
android:name="android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS"/>
permission, and override it, but the service still gets killed. You can find my Service class, Receiver class, and manifest below.

startActivity() does nothing even when the Intent is specified correctly

I am trying to open an activity from the launcher activity when an FCM-generated notification gets clicked. The startActivity function does nothing even when the log statement written above gets executed. Following are some relevant files/functions, please tell why is the ConversationDetailActivity not starting:
The function which starts another activity from LoginActivity
void handleNotificationClick()
{
if (getIntent().getExtras() != null)
{
for (String key : getIntent().getExtras().keySet())
{
Object value = getIntent().getExtras().get(key);
System.out.println("----- pushNotif Key: " + key + " Value: " + value);
}
Intent intent;
if(getIntent().getStringExtra(Master.KEY_PUSH_NOTIFICATION_CATEGORY).equals(Master.KEY_PUSH_NOTIFICATION_CONVERSATION))
{
intent = new Intent(LoginActivity.this, ConversationDetailActivity.class);
}
else
{
intent = new Intent(LoginActivity.this, ApprovalDetailActivity.class);
if(getIntent().getStringExtra(Master.KEY_PUSH_NOTIFICATION_APPROVAL_TYPE).equals("I"))
intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_VERIFICATIONS);
else if(getIntent().getStringExtra(Master.KEY_PUSH_NOTIFICATION_APPROVAL_TYPE).equals("A"))
intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_APPROVALS);
else
intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_COMPLETED);
intent.putExtra(Master.KEY_IS_FROM_CONVERSATION, false);
}
intent.putExtra(Master.KEY_PUSH_NOTIFICATION_POST_ID , getIntent().getStringExtra(Master.KEY_PUSH_NOTIFICATION_POST_ID));
intent.putExtra(Master.KEY_IS_FROM_PUSH_NOTIFICATION, true);
intent.putExtra(Master.KEY_POSITION, 0);
System.out.println("----- starting new activity from handleNotificationClick");
LoginActivity.this.startActivity(intent);
LoginActivity.this.finish();
}
}
The sendNotification function from which the notification is generated
private void sendNotification(String messageBody)
{
Intent intent;
System.out.println("----message body: " + messageBody);
if(notificationBundle.getCategory().equalsIgnoreCase(Master.KEY_PUSH_NOTIFICATION_CONVERSATION))
{
intent = new Intent(this, ConversationDetailActivity.class);
}
else
{
intent = new Intent(this, ApprovalDetailActivity.class);
if(notificationBundle.getApprovalType().equals("I"))
intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_VERIFICATIONS);
else if(notificationBundle.getApprovalType().equals("A"))
intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_APPROVALS);
else
intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_COMPLETED);
intent.putExtra(Master.KEY_IS_FROM_CONVERSATION, false);
}
intent.putExtra(Master.KEY_PUSH_NOTIFICATION_POST_ID , notificationBundle.getPostID());
intent.putExtra(Master.KEY_IS_FROM_PUSH_NOTIFICATION, true);
intent.putExtra(Master.KEY_POSITION, 0);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT | PendingIntent.FLAG_UPDATE_CURRENT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.mnet_icon)
.setContentTitle(getString(R.string.app_name))
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
int random = (int) ((new Date().getTime() / 1000L) % Integer.MAX_VALUE);
notificationManager.notify(random, notificationBuilder.build());

Try Adding android:exported="true" to the activity in AndroidManifest.xml

First finish Login activity, and then call start activity.
LoginActivity.this.finish();
LoginActivity.this.startActivity(intent);

In your manifest, define your class which you want to open like this
<activity
android:name=".activities.ApprovalDetailActivity"
android:exported="true"
android:screenOrientation="portrait"
android:theme="#style/MyMaterialTheme"
android:windowSoftInputMode="stateHidden">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

Nothing works for me except this one. The thing work for me is simple. Make sure you add this in the activity that you want to open directly.
<intent-filter>
<action android:name="MainActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
And from the push notification you must add a new payload: click_action
it will looks like this -
"notification": {
"title": "hello",
"body": "test message",
"click_action": "MAIN_ACTIVITY"
},
Note: You can name it as you want MAIN_ACTIVITY but must be same in both place.

ActivityNotFoundExceptionstarted appearing out of nowhere

Before my application was working fine. I just created a new class (within the same package) and also declared it in the manifest, still I get a ActivityNotFoundException and sometimes NoClassDefFoundException.
TestActivity.java
public class TestActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.order_summary);
}
}
Activity_NewOrder.java
public class Activity_NewOrder extends Activity
try {
//Also tried Intent intent = new Intent(Activity_NewOrder.this, TestActivity.class);
Intent intent = new Intent(getApplicationContext(), TestActivity.class);
startActivity(intent);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
