Denied permission for ContentProvider - kotlin

Question

I have two applications that I want to send data between, lets call them ProviderApp and ResolverApp.
In the ProviderApp I have a Content Provider. Here is the AndroidManifest file for this app.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.rewardreacher">
<permission android:name="android.permission.READ_GOALS"
/>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher_reward"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_reward_round"
android:supportsRtl="true"
android:theme="#style/Theme.RewardReacher">
<provider
android:name=".provider.MyContentProvider"
android:authorities="com.example.rewardreacher.provider.MyContentProvider"
android:readPermission="android.permission.READ_GOALS"
android:multiprocess="true"
android:enabled="true"
android:exported="true">
</provider>
<activity
android:name=".MainActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Now I am trying to access this data from ResolverApp using this AndroidManifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.workouttracker">
<uses-permission android:name="android.permission.READ_GOALS"/>
<queries>
<provider android:authorities="com.example.rewardreacher.provider.MyContentProvider"/>
</queries>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher_workout"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_workout_round"
android:supportsRtl="true"
android:theme="#style/Theme.WorkoutTracker">
<activity
android:name=".MainActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
And MainActivity
package com.example.workouttracker
import android.Manifest
import android.annotation.SuppressLint
import android.content.ContentValues.TAG
import android.content.pm.PackageManager
import android.net.Uri
import android.os.Build
import android.os.Bundle
import android.util.Log
import android.view.View
import android.widget.TextView
import androidx.appcompat.app.AppCompatActivity
import androidx.core.app.ActivityCompat
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
}
private fun isStoragePermissionGranted(): Boolean {
return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
== PackageManager.PERMISSION_GRANTED
) {
Log.v(TAG, "Permission is granted")
true
} else {
Log.v(TAG, "Permission is revoked")
ActivityCompat.requestPermissions(
this,
arrayOf(Manifest.permission.READ_EXTERNAL_STORAGE),
1
)
false
}
} else { //permission is automatically granted on sdk<23 upon installation
Log.v(TAG, "Permission is granted")
true
}
}
#SuppressLint("Range")
override fun onRequestPermissionsResult(
requestCode: Int,
permissions: Array<String>,
grantResults: IntArray
) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults)
if (grantResults.size > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Log.v(TAG, "Permission: " + permissions[0] + "was " + grantResults[0])
val resultView = findViewById<View>(R.id.res) as TextView
val cursor = contentResolver.query(CONTENT_URI, null, null, null, null)
if (cursor!!.moveToFirst()) {
val strBuild = StringBuilder()
while (!cursor.isAfterLast) {
strBuild.append("""
${cursor.getString(cursor.getColumnIndex("id"))} - ${cursor.getString(cursor.getColumnIndex("name"))} - ${cursor.getString(cursor.getColumnIndex("frequency"))} - ${cursor.getString(cursor.getColumnIndex("performed"))}
""".trimIndent())
cursor.moveToNext()
}
resultView.text = strBuild
} else {
resultView.text = "No Records Found"
}
}
}
var CONTENT_URI = Uri.parse("content://com.example.rewardreacher.provider.MyContentProvider/goals")
#SuppressLint("Range")
fun onClickShowDetails(view: View?) {
// inserting complete table details in this text field
isStoragePermissionGranted()
// creating a cursor object of the
// content URI
}
}
But I keep getting "Permission is revoked" from the isStoragePermissionGranted()...
What am I doing wrong?
