ACTION_VIEW (for APKs) and ACTION_INSTALL_PACKAGE were deprecated in Android 10. You need to switch to the PackageInstaller API.
This sample app demonstrates the basics for getting a simple APK installed. The guts are in the MainMotor:

import android.app.PendingIntent
import android.content.Intent

import kotlinx.coroutines.Dispatchers
import kotlinx.coroutines.launch
import kotlinx.coroutines.withContext
private const val NAME = "mostly-unused"
private const val PI_INSTALL = 3439
class MainMotor(app: Application) : AndroidViewModel(app) {
private val installer = app.packageManager.packageInstaller
private val resolver = app.contentResolver
fun install(apkUri: Uri) {
viewModelScope.launch(Dispatchers.Main) {
installCoroutine(apkUri)
}
}
private suspend fun installCoroutine(apkUri: Uri) =
withContext(Dispatchers.IO) {
resolver.openInputStream(apkUri)?.use { apkStream ->
val length =
DocumentFile.fromSingleUri(application, apkUri)?.length() ?: -1
val params =
PackageInstaller.SessionParams(PackageInstaller.SessionParams.MODE_FULL_INSTALL)
val sessionId = installer.createSession(params)
val session = installer.openSession(sessionId)
session.openWrite(NAME, 0, length).use { sessionStream ->
apkStream.copyTo(sessionStream)
session.fsync(sessionStream)
}
val intent = Intent(application, InstallReceiver::class.java)
val pi = PendingIntent.getBroadcast(
application,
PI_INSTALL,
intent,
PendingIntent.FLAG_UPDATE_CURRENT
)
session.commit(pi.intentSender)
session.close()
}
}
}
When an activity or fragment calls install(), supplying a Uri to the APK, I use PackageInstaller to install it:
- Get a
PackageInstaller from PackageManager
- Create a
SessionParams and open a session from it
- Write the bytes of the APK (read from an
InputStream from the Uri) to an OutputStream supplied by that session
- Call
commit() to actually begin the installation process, with results being delivered back to the app via a PendingIntent
- Call
close() to close up the session
The API is clunky, but it is designed to handle a wide range of scenarios, including "App Bundle"-style multi-APK installations.
