I can't launch widgets on android 11.
This code works on my android 9 phone,
but android 11 Google Pixel 3a emulator not working.
what should I do for this.
Ok, so what I want to do is create a widget that will simply launch another application when the widget is pressed.
Widget Xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:text="Whatsapp Launch"
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

<Button
android:layout_marginLeft="30dp"
android:text="Spotify Launch"

Widget Class
class SimpleAppWidget : AppWidgetProvider() {
override fun onUpdate(
context: Context,
appWidgetManager: AppWidgetManager,
appWidgetIds: IntArray
) {
// There may be multiple widgets active, so update all of them
for (appWidgetId in appWidgetIds) {
updateAppWidget(context, appWidgetManager, appWidgetId)
}
}
private fun updateAppWidget(
context: Context, appWidgetManager: AppWidgetManager,
appWidgetId: Int
) {
// Construct the RemoteViews object
val views = RemoteViews(context.packageName, R.layout.simple_app_widget)
// Construct an Intent object includes web adresss.
val launchIntent12 = context!!.packageManager.getLaunchIntentForPackage("com.spotify.music")
val launchIntent122 = context!!.packageManager.getLaunchIntentForPackage("com.whatsapp")
// In widget we are not allowing to use intents as usually. We have to use PendingIntent instead of 'startActivity'
val pendingIntent = PendingIntent.getActivity(context, 0, launchIntent122, 0)
val pendingIntent2 = PendingIntent.getActivity(context, 0, launchIntent12, 0)
// Here the basic operations the remote view can do.
views.setOnClickPendingIntent(R.id.button, pendingIntent)
views.setOnClickPendingIntent(R.id.button2, pendingIntent2)
// Instruct the widget manager to update the widget
appWidgetManager.updateAppWidget(appWidgetId, views)
}
}
First, you will need to add package visibility rules to your manifest. As it stands, getLaunchIntentForPackage() is probably returning null. After fixing this, fully uninstall and reinstall the app before continuing.
Also:
Use unique IDs for your PendingIntent objects (they are both set for 0 in the second parameter to getActivity())
Consider using PendingIntent.FLAG_UPDATE_CURRENT for the fourth parameter to getActivity()

As long as I don't turn the phone off (even if the application is closed), the forward notification that I have created with the alarm manager in my android-java mobile application does not have a problem. But when I restart the phone before the notification time comes, it doesn't work even if it's time for my notification. Can you please help? Thanks.

I added the following permissions to my manifest file but it didn't work
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<receiver android:name=".MyReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</receiver>
This is the expected behavior. If you turn off your device, all alarms are deleted. So, to workaround this issue, you must register for boot complete broadcast and re-schedule your alarm.
You can find more details on how to do it in the following question/answer:
does Alarm Manager persist even after reboot?
I think you can try use work manager, which will be executed by system.
WorkManager is the recommended solution for persistent work. Work is persistent when it remains scheduled through app restarts and system reboots. Because most background processing is best accomplished through persistent work, WorkManager is the primary recommended API for background processing.
I have 2 kinds of notification builders in my MyFirebaseMessagingService.java, one passes string called 'lecture_date' and opens Lectures_graph.class while the other one passes string called 'web_url' and opens webview_base.class when clicked.
What i want to achieve : fully working FCM notifications even when app is killed, notifications must open activity (with extras) once they are clicked.
How far i am : I can receive notifications to open Lectures_graph.class with intent extras, everything loads and works just fine. Even if i receive notifications for webview_base.class activity, nothing happens when i click on notification.
There might be one thing that points to problem - Logcat often tells me this :
E/FirebaseMessaging: Notification pending intent canceled
Im using PHP to send out notifications (that code is 100% correct and working), code below shows represents the idea of JSON sent out for webview_base.class activity. To send out notifications for Lectures_graph.class activity, i just have to swap click_action from "OPEN_ACTIVITY_WEBVIEW" to "OPEN_ACTIVITY_LECTURES" and change the data payload. PHP for webview_base.class activity sends away such data :
$msg = array
(
'body' => 'test body',
'title' => "test title",
'click_action' => 'OPEN_ACTIVITY_WEBVIEW',
'channelId' => "newsfeed",
'vibrate' => 1,
'sound' => 1
);
//sends notifications via topics
$fields = array
(
"data" => [
'web_url' => $_POST['notification_url']
],
'notification' => $msg,
'to' => '/topics/test'
);

a while ago i was getting an error in logcat that said something like "default FCM channel is not defined", but im not quite sure thats the problem.
Even if i searched across the whole web, i would like to see better solutions/suggestions for notification (with its payload) handling when app is killed.
So i fixed my nightmare and here is how :
Since i cant open more than one specific activity from notifications, why could i just open my apps main class and handle extra variable from there ?
Instead of having for each wanted activity
<intent-filter>
<action android:name="OPEN_ACTIVITY_???????" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
i made this :
<activity
android:name=".MainActivity"
android:launchMode="singleTask"
android:configChanges="orientation|keyboardHidden|screenSize">
<intent-filter>
<action android:name="OPEN_APP" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
I added extra variable to notifications payload (examle : 'activity' => 'webview') and renamed click_action in my PHP code. I handled all payloads in MainActivity.class and called wanted android activity from there. MainActivity code :
Bundle extras = getIntent().getExtras();
if(extras == null) {
Log.e("MainActivity", "No Activities passed in notification extras");
} else {
//get opening activity from notification payload
String activity = extras.getString("activity");
if( activity != null){
switch (activity){
//webview activity
case "webview":
//gets url for webview
String web_url = extras.getString("web_url");
if(web_url != null){
finish();
startActivity(new Intent(this, webview_base.class).putExtra("web_url", web_url));
}
break;
//lectures activity
case "lectures":
//gets lecture date
String lecture_date = extras.getString("lecture_date");
if(lecture_date != null){
finish();
startActivity(new Intent(this, Lectures_graph.class).putExtra("lecture_date", lecture_date));
}
break;
}
}
}
Hope this helps someone, someday..
Cheers.
Whenever I reboot my phone or upgrade the app (on my test device and on Android emulator) the widget stops updating until I create a new instance of the widget. Then both instances of the widget will start updating again. I assume it's something with calling the onUpdate() on old WidgetIds, but I can't figure it out.
Here's a small snipped of my code.
public class NewAppWidget extends AppWidgetProvider {
private static final String refresh = "b_refresh";
static void updateAppWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId) {
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.new_app_widget);
Intent intent = new Intent(context, NewAppWidget.class);
intent.setAction(refresh);
intent.putExtra("appWidgetId", appWidgetId);
views.setOnClickPendingIntent(R.id.refresh, PendingIntent.getBroadcast(context,0,intent, PendingIntent.FLAG_UPDATE_CURRENT));
appWidgetManager.updateAppWidget(appWidgetId, views);
}
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
for (int appWidgetId : appWidgetIds) {
updateAppWidget(context, appWidgetManager, appWidgetId);
}
}
#Override
public void onReceive(Context context, Intent intent) {
if(refresh.equals(intent.getAction())) {
Toast.makeText(context, "Clicked2", Toast.LENGTH_LONG).show();
}
}
}
EDIT: Here's my manifest.xml
<application
android:allowBackup="true"

Add a call to super.onReceive() to your onReceive().
Explanation
If you look at the source for the base class onReceive(), you can see that it implements part of the framework logic for managing Widget lifecycle. (Also hinted at by the docs). It handles APPWIDGET_UPDATE and is, in fact, what's responsible for calling onUpdate() in the first place. (E.g., when the system boots up, and it needs to draw your initial widget, it sends your app an APPWIDGET_UPDATE, which gets passed to onReceive()). So, I'm not 100% sure how onUpdate() was ever getting called, in your case, but I assume you have some code somewhere else that calls updateAppWidget(), and that's the only reason your widgets appeared to work even momentarily.
I want to make an app for Android TV, so I am using the default Android TV activity in Android Studio as a template for my project, I want to add a button in the VideoDetailsFragment, this button only appears after the package manager detects that a secondary activity is active.
If the package manager detects my secondary activity is active and running it should show a button to disable it and if the activity is disabled it should show a button to enable it, but... the package manager can't get the name of the activity, it can't actually get the name of any package or activity, it always show NameNotFoundException both of my activities are android:name="android.intent.action.MAIN" in the Manifest because I want to add a launch intent for both from the launcher, but the secondary activity has the label android:enabled="false" because the button I want to put in the VideoDetailsFragment is supposed to enable and disable that activity.

And here is a screenshot of the error show in android studio:
Here is another screenshot showing one of the suggested answer, but it doesn't work neither:
I wrapped that into a try catch, but when I run my app it always throw the NameNotFoundException in the Android Monitor.
What I am doing wrong?
You need to define the proper ComponentName:
new ComponentName("com.valecast.myapp", "com.valecast.myapp.SecondaryActivity");
and have a try catch:
try {
ActivityInfo info = pm.getActivityInfo(cn, 0);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}

Here i have gathered almost all the parts of code that i use to run/install.. my widget.Thanks in advance
Remove android:configure from your app widget metadata, or have it point to an activity to be used for configuring the app widget.
You can read more about configuration activities in the documentation.
change
android:configure="com.flashlight.standroid.FlashlightWidgetProvider"
with
android:configure="com.flashlight.standroid.WidgetProvider"
And make sure the Activity name is exactly wrote down on the android manifest.
