由 送分小仙女□ 提交于 2019-12-12 03:01:12
问题 Say I wanted to pass data from one activity/class to the other involving an integer data type.

Android getIntent().getExtras() returning null sometimes

由 不打扰是莪最后的温柔 提交于 2019-12-07 05:01:01
问题 I was going through Crashlytics logs for my app and found that there is a NullPointerException on some devices because getIntent().getExtras() is returning null. This behavior is seen only on a few devices and I am not able to reproduce this bug. I know that I can check in the activity if the Bundle is null and prevent the NullPointerException but I was more interested in finding out the root cause for this behavior. Edit: Source - listView.setOnItemClickListener(new AdapterView

Send argument through PendingIntent of NavDeepLinkBuilder

由 空扰寡人 提交于 2019-12-05 19:00:18
I'm having some difficulties sending an argument through a PendingIntent of a notification using NavDeepLinkBuilder . I'm able to get the destination Activity to launch by clicking the notification, but the Activity 's Intent doesn't contain the argument value that I passed it through the NavDeepLinkBuilder . The Intent instead returns the defaultValue that I set in the nav graph - "noJobId". Notification creation : val notification = NotificationCompat.Builder(context, context.getString(R.string.notification_channel_id_new_job)) ... .setContentIntent( NavDeepLinkBuilder(context)

Store and retrieve array list in Bundle in Android

由 ε祈祈猫儿з 提交于 2019-12-05 01:30:16
How do I store and retrieve an array list of values in a Bundle in Android? Any examples? Lets take if you array list has strings in it. ArrayList<String> al = new ArrayList<String>(); al.add("test1"); al.add("test2"); al.add("test3"); Now you can put it into bundle as follows: Bundle value= new Bundle(); value.putStringArrayList("temp1", al); If you have your own object type instead of "String" in ArrayList then you need to serialize that ArrayList object. eMich Serialize your arraylist using the Parcelable class. You can add Parcelables to the Bundle. The only way to store an arraylist in

Android Studio: Passing multiple values using intent PROVIDES ONLY 1 VALUE?

Does retrieving a parcelable object through bundle always create new copy?

由 喜欢而已 提交于 2019-12-04 17:22:07
问题 I'm passing a parcelable object to a fragment by adding into a bundle while creating the fragment. In onc instance modification to this parcelled object reflects modification in original object and in another case it is not. I'm a little baffled by this behaviour. Till now I have assumed retrieving a parcelled objects through a bundle always create new object[no sure whether it's shallow copy or deep copy]. Someone please clarify parcelable behaviour. 回答1: I was struggling with a similar
