QUESTION
So basically the issue I am facing is that my app is crashing whenever I try to assign some value like .settext() to some view.
Basically, I have Main activity from where I have created a navigation drawer. From the Navigation drawer I have two menu options each of which when clicked on open up a fragment. Also as the first fragment is also the home screen so I launch the first fragment whenever I open Main activity.
Now, the second fragment is where I face issue. I have a fragment layout with some views as well as a Fragment java file. When ever I try to assign those views some value from the java file the app crashes. I have pasted both the code of my fragment xml file and java file as well as the error below.

When I open large audio files, I get an out of memory error.

...ANSWER
Answered 2020-Sep-09 at 11:33The simple answer is it was running in 32bit (x86) which doesn't have enough allocation for 50,000,000+ samples.
Instead, changing the program to x64 has solved that specific problem.
That's what I like about SO where you can pool resources from so many people and learn as you ask questions.
QUESTION
I am working on an app that draws waveforms in a window that slides in and out of the main view. I find that if I open the sliding view several times the app begins to slow down. I have discovered that drawing the waveforms with a UIBezierPath is slowing down my app. I'm wondering if there is something that I need to do to terminate the current UIBezierPath and avoid a memory leak. Any suggestions or advice is appreciated I'm not super familiar with using UIBezierPath. Thanks in advance for the help!!!
...ANSWER
Answered 2020-Jul-07 at 23:55Don't make the path instance a class member variable - just declare a local UIBezierPath variable in your draw() method.
QUESTION
I'm trying to implement a FIFO using SV taking dynamic arrays & queues. However i'm unable to view waveform of the dynamic array/queues in the waveviewer. Does anyone know how to view waveform of dynamic arrays or it is not possible?
Result in EDA Playground:
Error message : [2020-05-28 01:53:22 EDT] iverilog '-Wall' '-g2012' design.sv testbench.sv && unbuffer vvp a.out ivl: eval_object.c:65: eval_darray_new: Assertion `0' failed. Aborted (core dumped) Exit code expected: 0, received: 1

ANSWER
Answered 2020-May-28 at 06:45The VCD text format was never enhanced to support many of the datatypes that SystemVerilog introduced to Verilog, especially none of the dynamically sized arrays.
You won't be able to use any of the tools on EDAPlayground since it relies on VCD files from $dumpvars to show waveforms.

Background: I'm trying to animate a wave using BAFluidView. My goal is pretty simple: start the animation when a button is tapped, stop it when it is tapped again. The pod (linked above) provides all of the code to manage this.

QUESTION
Above GIF is current look of my music player.
The center layout is WaveView and front of that is a simple musical note vector-drawable.
I first tried to set Waveview progress according to SeekBar's progress without any song playing to test it. And it worked perfectly fine (Seekbars current progress/100 which is 0.01 to 1.00).
Now what I want to do is set WaveView's Water Level (height of water) according to song progress.
When song will play, the water level will be set from 0.0f to 1.0f and revealing the White Music note icon.
Note that the WaveView's water level can only be set from 0.0f to 1.0f.
I tried multiple ways but could not solve this problem.
Here is my code which should return 0.01, 0.02 and so on ... :

Install WaveView
You can use WaveView like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the WaveView component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
