I am using below code to retrieve all apps package names from phone. public List<String> GetAllInstalledApkInfo(){ List<String> ApkPackageName = new ArrayList<>(); Intent intent = new Intent(Intent.ACTION_MAIN

问题 I do not know how to implement a filter query properly inside the Repository and the ViewModel to use it to display the filtered string in a Textview or anything else really. My Entity, Dao, Repository, and ViewModel are as follows: User.kt @Entity(tableName = "user_data") data class User ( @PrimaryKey(autoGenerate = true) val id: Int, @ColumnInfo(name = "name") val name: String ) UserDao.kt @Dao interface UserDao { @Insert fun addUser(user: User) @Query("SELECT name FROM user_data WHERE name

问题 I'm trying to show call logs from Sim1 and Sim2 separately. I'm getting all call logs, but not able to differentiate it whether it is from Sim1 or Sim2. I have tried below code, val managedCursor = activity?.contentResolver?.query(CallLog.Calls.CONTENT_URI, null, null, null, null) managedCursor?.let { val number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER) val name = managedCursor.getColumnIndex(CallLog.Calls.CACHED_NAME) val type = managedCursor.getColumnIndex(CallLog.Calls.TYPE) val

问题 When an application receives push notification from FCM , it calls onMessageReceived . (See 1, 2 or 3.) When a user taps the notification , it launches the applications, then it sends a request to a server that the user has read the notification. I want to know when a device received a push notification, but the user swiped it (or cleared all notifications). I want to send a request to the server that the user simply cancelled the notification . I tried to send BroadcastReceiver and show logs

问题 How do I open another app in a split screen in the android N (SDK 24)? In the documentation I found this: Launch New Activities in Multi-Window Mode When you launch a new activity, you can hint to the system that the new activity should be displayed adjacent to the current one, if possible. To do this, use the flag Intent.FLAG_ACTIVITY_LAUNCH_TO_ADJACENT. Passing this flag requests the following behaviour: If the device is in split-screen mode, the system attempts to create the new activity

问题 So let me preface this by saying downloading the Netflix App is not an option. So my thought is to just make a wrapper app that loads the netflix website in a WebView. This works for login/navigation; however, whenever you hit the play button to start playing the video, there is no response and no output in logcat. I'm looking for a way to see more debug messages from the WebView or a way to get the video playing. Using Android 4.4.4 by the way. View layout = LayoutInflater.from(mActivity)
