I am currently having trouble while trying to display a "blast" view from the media playing, using this library: https://github.com/gauravk95/audio-visualizer-android
I am working in an activity coded using Kotlin
I did as advised in the readme, but am having an issue when my activity starts:
E/AudioEffect: set(): AudioFlinger could not create effect e46b26a0-dddd-11db-8afd-0002a5d5c51b / `�?�v, status: -1

Process 31116 terminated.
I have declared both RECORD_AUDIO and MODIFY_AUDIO_SETTINGS permissions in the manifest.
Here is my code for the activity:
class AudioPlayerActivity : BaseAdventureActivity(R.layout.activity_audio_player, true) {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val dataLocation = intent.getSerializableExtra(EXTRA_LOCATION) as DataLocation
val path = "sample_audio_happy"
var mediaPlayer = MediaPlayer.create(this, dataLocation.getUri(path, this, adventure))
mediaPlayer.start()
if (mediaPlayer.audioSessionId != -1) blast.setAudioSessionId(mediaPlayer.audioSessionId)
}
override fun onDestroy() {
super.onDestroy()
blast.release()
}
When I comment the line with setAudioSessionId everything works fine (but of course without showing the visualisation).
Would anyone know where this error could come from?
Indeed, #Tenfour04 is right. Here are the two lines of code that were required:
if (ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, Array(1){Manifest.permission.RECORD_AUDIO}, 0)
}
Just add before stting audioSessionId, and it should work.
Thanks for your help!

When I try an app I was developing in the Android Studio emulator, the following message appears: 'App keeps stopping' and it doesn't open.
This is the code for the MainActivity:
import android.content.Intent
import android.os.Bundle
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity
import androidx.navigation.findNavController
import androidx.navigation.ui.AppBarConfiguration
import androidx.navigation.ui.setupActionBarWithNavController
import com.example.bookapplication.databinding.ActivityMainBinding
class MainActivity : AppCompatActivity() {
private lateinit var appBarConfiguration: AppBarConfiguration
private lateinit var binding: ActivityMainBinding
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
val navController = findNavController(R.id.nav_host_fragment_content_main)
appBarConfiguration = AppBarConfiguration(navController.graph)
setupActionBarWithNavController(navController, appBarConfiguration)
binding.libroLeidos.setOnClickListener { Toast.makeText(this, "Entrando en Libros Leídos", Toast.LENGTH_LONG).show()
val primerIntent = Intent(this, librosLeidos::class.java)
startActivity(primerIntent)
}
binding.libroPendiente.setOnClickListener { Toast.makeText(this, "Entrando en Libros Pendientes", Toast.LENGTH_LONG).show()
val segundoIntent = Intent(this, librosPendientes::class.java)
startActivity(segundoIntent)
}
}}
On the other hand, in the LogCat, I get this message:

The problem is that I don't know where to go to fix it. I am new to this and there are many things that are beyond me. I have found other similar questions but I have not understood well how to proceed.
Thank you very much.
The stacktrace from logcat points you to the call to findNavController (which appears to be on line 24 in your source code), where it says that it can't find the id R.id.nav_host_fragment_content_main in your view.
Is R.id.nav_host_fragment_content_main defined in activity_main.xml? If so, the second call to setContentView() is replacing that view with whatever is in binding.root. In that case, removing the second call could fix your issue.
If R.id.nav_host_fragment_content_main is supposed to be defined in binding.root, I think you'll need to include the implementation of com.example.bookapplication.databinding.ActivityMainBinding in your question so we can better understand what' going on.
In any case, you shouldn't call setContentView() twice, as #TylerV said.
Hey guys I wanted to build a counter app. But this error pops up when I want to test it:

I don't know if I have coded everything correctly because I just started learning Android Studio, so I still don't know a lot about it. This is my code (I'm new to Kotlin):
package com.example.change
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.widget.Button
import android.widget.TextView
class MainActivity : AppCompatActivity() {
private var counter1 = 0;
private lateinit var counterRed1: TextView
private lateinit var fighter1: Button
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
counterRed1 = findViewById(R.id.counterRed1);
fighter1.setOnClickListener {
counter1 ++
counterRed1.text = (Integer.toString(counter1))
}
}
}
You have missed initializing your fighter1 button field. You need to initialize it just like you've initialized the counterRed1 text field.
counterRed1 = findViewById(R.id.counterRed1);
fighter1 = findViewById(R.id.fighter1);
Also make sure your activity_main layout file has a Button with the id fighter1.
I am trying to initialize TextView in Kotlin as following
val textSelectedFood = findViewById<TextView>(R.id.textSelectedFood) as TextView
I also tried this
val textSelectedFood: TextView = findViewById<TextView>(R.id.textSelectedFood) as TextView
And also this
val textSelectedFood: TextView = findViewById(R.id.textSelectedFood) as TextView
And this
val textSelectedFood: TextView = findViewById<TextView>(R.id.textSelectedFood)
But still getting following errors. Don't know why

I got hints from this question.
but the code changed a lot over the year.
That's why I am writing the current solution code in the below which solved my problem.
private lateinit var textSelectedFood: TextView // withoud lateinit code will show error
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
textSelectedFood = findViewById(R.id.textSelectedFood)
}
If you do not have to "findViewById" have many better and safer options:
1.synthetic (deprecated)
Call the view directly in your code.
2.view binding
For more information check this link:https://developer.android.com/topic/libraries/view-binding
This technique is old now, just use "View binding".
Or you can just call the view by it's id and that'll be it.
In your case:
textSelectedFood.text = "Example of doing something"
Im investigating de.undercouch:citeproc-java:2.0.0 within my current Android application.
I cannot identify a ScriptEngine that works on Android with citeproc-java.
my Gradle resembles this:-
ext {
compileSdkVersion = 30
minSdkVersion = 26
targetSdkVersion = 30
}
dependencies {
implementation 'io.apisense:rhino-android:1.1.1'
implementation 'de.undercouch:citeproc-java:2.0.0'
implementation 'org.citationstyles:styles:20.11'
implementation 'org.citationstyles:locales:20.11'
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'com.google.android.material:material:1.2.1'
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.4.10"
}
Citeproc requires javax.script.ScriptEngineManager which is not available on the Android platform therefore I have substituted io.apisense:rhino-android:1.1.1
I am now facing this exception...

The citeproc code that causes this exception is taken straight from their examples...
private fun what() {
val citeproc = CSL(MyItemProvider(), "ieee")
citeproc.setOutputFormat("text")
citeproc.registerCitationItems("ID-1", "ID-2", "ID-3")
val s1 = citeproc.makeCitation("ID-1")
println(s1[0].text)
//=> [1] (for the "ieee" style)
//=> [1] (for the "ieee" style)
val s2 = citeproc.makeCitation("ID-2")
println(s2[0].text)
//=> [2]
//=> [2]
val bibl = citeproc.makeBibliography() //EXCEPTION RAISED HERE!!!!!!
for (entry in bibl.entries) {
println(entry)
}
}
I've created an AndroidJUnit to investigate this issue.
While stepping through the code I have found the issue is an arrayOutOfBoundsException accessing the strings[]
The array has only 12 entries however the index is 39
as shown in the AS image
As I saw values shown in debugger its shows 12 items in iCode[] array .
And from.pc has value 39 that is the cause of array index out of exception.
As par your code from.pc value increase by pre increments by one condition and in other value increase by post increments adding 2 each time.
And you are using continue with out checking size of array that is always creates exception.
You should check your conditions because it look like array does initialize properly if expect value at 39th position or increments in index are improper.
I'm trying to request permistions as it is written in the https://developer.android.com/training/permissions/requesting
Something is wrong.
In Logcat there is no Log.d output from callback of registerForActivityResult.
proggy() not run from callback. It set permissions okey.
But
when I changed
implementation 'androidx.activity:activity-ktx:1.2.0-alpha06'
to
implementation 'androidx.activity:activity-ktx:1.2.0-alpha07'
I got:
