How to open an APK file for all Android versions

Question

Background

So far, there was an easy way to install an APK file, using this intent:

    final Intent intent=new Intent(Intent.ACTION_VIEW)
                 


        

Answer 1

just for those who wonder how to finally install an APK properly, here:

@JvmStatic
fun prepareAppInstallationIntent(context: Context, file: File, requestResult: Boolean): Intent? {
    var intent: Intent? = null
    try {
        intent = Intent(Intent.ACTION_INSTALL_PACKAGE)//
                .setDataAndType(
                        if (VERSION.SDK_INT >= VERSION_CODES.N)
                            androidx.core.content.FileProvider.getUriForFile(context, context.packageName + ".provider", file)
                        else
                            Uri.fromFile(file),
                        "application/vnd.android.package-archive")
                .putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true)
                .putExtra(Intent.EXTRA_RETURN_RESULT, requestResult)
                .addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
        if (VERSION.SDK_INT < VERSION_CODES.JELLY_BEAN)
            intent!!.putExtra(Intent.EXTRA_ALLOW_REPLACE, true)
    } catch (e: Throwable) {
    }
    return intent
}
