kandi X-RAY | renderthread Summary
This library wraps the native RenderThread, providing a type-safe way to run custom animations off the UI thread. Read about what it means in this Medium article. It transparently falls back to using the standard drawing methods if the hidden APIs aren't available, or whenever hardware acceleration is not enabled on the specified Canvas.

QUESTION
The app has:
- ListView listing player names from a DB table (only one column, so it is primary key)
- EditText to write the new name
- Button to update the name of player in the list
*there are more things, but i don´t want to make it more messy
I can click a name from the list and write a new name in the EditText. When you press the button that name is updated in the list.
Everything works correctly, but there is a problem. When I write a name that it is already in the list the app fails because primary keys cannot be repeated.
Is there some way to say "if EditText text already exists in the DB... then show a toast"
I already tried "if result of db.update is -1...then show a toast", but it doesn´t work.
This is the method in MainActivity:

You have a UNIQUE index on the NUM_JUG column (perhaps implicit if NON_JUG is defined with PRIMARY KEY) and you are using the standard update method which uses the default conflict action of ABORT and therefore fails if an attempt is made to duplicate a NOM_JUG value.
As secondary issue is that the SQLiteDatabase update method returns the number of updates (see extract and link below) (same for updateWithOnConflict). The number returned will never be -1 it will be 0 or more (0 indicating that no updates have been applied).
As per SQLite Database - Update
Returns
int the number of rows affected
Fix
To fix the main issue you should use the updateWithOnConflict method. This takes a 4th parameter a conflict and you probably want IGNORE so you could use :-
QUESTION
The WebView Code
...ANSWER
Answered 2021-May-30 at 13:47The problem is that the Webview (ModalView) assigns its own parent. This is a feature of the ModalView. By returning a Webview instance in your build() method, you are attempting to set the App as the parent of the Webview. That causes the error you are seeing. You can solve this by returning something other than a Webview:
QUESTION
Delphi 10.3.3
got here Android 10 (also Android 8). Battery Optimization is off . The problem only happens if my Device is on the charger. After approximately 48hrs it dies .
I tried to solve this by waking the device up periodically (after 8hrs) . Today it last sent data to the server at 3:00 , so I thought it is dead. But to my big surprise , it still woke up at 08:00 . Unfortunately after touching the screen , to try to open something . Android forced me to close the app.
Here is the part of the code :
(excuse me for the length, it looks to be long , but is is the bare minimum , I thought I'd include every procedure and function I use in order to perhaps help someone smarter then me see if I am leaking memory or doing something horrible, note : this very same code is NOT crashing or hanging after weeks if Device is not on the charger)
...ANSWER
Answered 2021-Mar-31 at 10:38IIRC on mobile devices there is no guarantee that the Android/iOS system will let an application live forever. It is very possible that your app is killed by the OS sending a SIG_ABRT after a while, to release resources.
Another possibility is that there is an OOM after too many threads. The log error indicates that there is a problem creating a thread.
Perhaps each DB connection uses a thread, which is not released, so after a while, it crashes. Please remove the DB connection and try again. It may help isolate the root cause of your problem. Also try to log the memory consumption, to see if there is no leak for this long-standing app.
Anyway, I would rather use REST service over HTTPS+JSON for app communication, instead of the bloated DataSnap RAD client.

I'm a newbie to fixing memory leaks and I don't really understand how I should remove them, especially in custom views. In this particular case I have a custom MapLegendView, which is being used in a MapPageFragment.

Answered 2021-Mar-04 at 20:50If someone else is wondering too, as it was said in a comments section, I should have removed listeners right in the OnDetachedFromWindow() method(before the super call of it!!). Also I've cleared onClickListeners in necessary fragments and called this method for my custom view in OnDestroyView(), so now it looks like:

QUESTION
Being new to MediaPipe, I am not familiar with concept of graph, node, subgraph etc.
After building an aar file of BoxTracking, unable to run it within a Android Studio gradle based project due to some unknown input and output parameters required by model
On comparing HandTracking graph and BoxTracking graph using the visualizer tool and with a working project of HandTracking with aar file added as lib, I added new required input streams and side packets as seen in the graph.
Results are always some errors, mainly due to something wrong in inputs or BoxTracking being a subgraph which is used directly. How to know which input is required and data type of input to run this?
...ANSWER
Answered 2021-Feb-20 at 07:29Datatypes required as input and output was not included in the default build, the build configurations has to be modified to include box_tracker.proto and its dependencies.

Answered 2021-Jan-19 at 13:52You cannot mix the fixed function matrices with the matrix transformations in 3.30 core shader. This means that the instruction GL.MatrixMode(MatrixMode.Projection); has no effect (except an OpenGL error in a core profile context). You have to add a projection matrix to the shader:
QUESTION
I have a method, setValuesCategories(View view, String category, int position), that I use to programmatically set the text of several TextViews in a GridLayout. This method is called the first time when the Fragment is created, with the String value of the first item in a Spinner. The TextViews declared inside the method has a value and the text is correctly changed.
The problem is when we select a different item in the spinner and the same method is called again. In this case, the TextViews declared within the method has a null value and I get a NullPointerException.
I don't understand at all why I am getting this, since the method is synchronized and this should prevent a second thread to try to assign the String value before the TextView object is initialized.
Thank you in advance!
...ANSWER
Answered 2021-Jan-22 at 18:34The parameter View view in the method SetValuesCategories was shadowed in the Spinner listener.
Got it solved by renaming this parameter in the listener.
public void onItemSelected(AdapterView adapterView, View v, int i, long l)

When enabling screens in react-native-screens, and having a screen which renders an component passed with an iframe HTML element, the app crashes while pressing the back button to return to the home screen. Full reproduction here.

- react-native-render-html-table-bridge: 0.6.1
ANSWER
Answered 2020-Dec-10 at 11:48This was caused by an incompatibility between react-native-webview and react-native-screens, which you must depend on if you are using @react-navigation/* packages.

I’m having a problem whereby the program crashes when I click the action_add_event icon button to add a new event in tge EventDetails activity.
