[Discontinued] Install an APK after downloading to ASD - works on all Android versions

[Taifun]

thank you for your contribution! looks great!

do you also accept feature requests? we also could use

• a method to list all files of the ASD including subdirectories and
• a method to create a subdirectory inside the ASD...

@Anke

This extension only works with the compiled app (APK).

only the Install method or all methods? To be able to test in the companion app it would be great, if as much methods as possible also work while using the companion app...

keep up the good work!

@Taifun

No, only the Install method.

@Taifun

• a method to list all files of the ASD including subdirectories and
• a method to create a subdirectory inside the ASD...

I'll try, but ...
(as you know I'm still a beginner with extensions).
Probably I need some help from an extension expert like you ...

@Taifun

keep up the good work!

Thanks, maybe you want to add a link to this extension (→ AI2 version) on your website:

because this link is only for the → Kodular version:

Extension to Install APK from app-specific directory (ASD) by BodyMindPower

[Anke]

EDIT: I forgot to mention that for devices with API < 19 (KitKat) WRITE_EXTERNAL_STORAGE permission is required, but this permission is granted at install-time for devices with API < 23 (because it is declared in the Manifest).

"On Android 4.4 (API level 19) or higher, your app doesn't need to request any storage-related permissions to access app-specific directories within external storage."
https://developer.android.com/training/data-storage/app-specific

[Zol]

Thank you for the great work!

[Anke]

I made an update and added some methods for creating subdirectories in the ASD as suggested by @Taifun:

Version 2 (Oct 28, 2020)
de.bodymindpower.InstallAPK.aix (9.6 KB)

You can now create the /Download dir in the ASD:

/storage/emulated/0/Android/data/edu.mit.appinventor.aicompanion3/files/Download/

and also subfolders in this dir, e.g.:

/storage/emulated/0/Android/data/edu.mit.appinventor.aicompanion3/files/Download/myAPKs/

@Anke

With this extension you can download an APK to the ASD (app-specific directory) and install it

sorry for my beginner question, what's the advantage of installing an APK to ASD ?

[Anke]

@patel

what's the advantage of installing an APK to ASD ?

See in the description above:

@Anke

This doesn’t require WRITE / READ_EXTERNAL_STORAGE permissions.

[patel]

I put my question wrong, why to make an app for installing another app ?

[Anke]

@patel

why to make an app for installing another app ?

There can be a variety of reasons.
Maybe you want to ask a user who was looking for it:

Problem with Anke's "Install apk from ASD extension"

Hi! I want to use @Anke 's Install APK extension. She wrote DeepHost's download extension is not require permission to download specific directory so i use that. [snip] I tried with original download path -android download directory-. Checking the download path showed that correctly. Gave error: Failed resolution of: Landroid/support/v4/content/FileProvider I thouth its ok, because Install APK extension need the appspecific directory. I modified as in Anke's example. As the picture shows. …

[Zol]

As Anke wrote there can be many reasons.
For example, in my current project i don't use playstore because of lead time and it is a private app, so i use the extension for self install the newest version from our own server. Of course it can be download and install manually, but not every user is software- and phone-guru so i make it easier for them.

I only wish it would be possible to avoid click on isntall too.

Dear Anke,
An error occurred such as image1
Apk (MIT AI) is run on an android version such as image2

@Boike_Rimba

Show your blocks.
And try this test APK:

Problem with Anke's "Install apk from ASD extension"

I have now created an extension that can also be used to download and install an APK with AI2 (using AndroidX libs). It should work with all versions of Android. The given download link (GoogleDrive) downloads an almost empty APK (only one button, 3.2 MB). But you can also set your own link to your app (APK). So check that on your devices with different Android versions, especially Android 10 and 11. [grafik]

• Does it work on your device?
• Which device and Android version do you have?

@Taifun

To be able to test in the companion app it would be great, if as much methods as possible also work while using the companion app

I've found the reason why the installAPK method doesn't work on devices with Android > 7. This line is missing in the Manifest of the Companion APK:

android:name="com.google.appinventor.components.runtime.multidex.MultiDexApplication"

If I add this line in the Manifest, it works fine also on Android 8, 9, 10, 11.
Maybe you or @ewpatton can tell more about this.

[ewpatton]

This shouldn't be needed on Android 5 and higher. Prior to Android 5, MultiDex was needed for larger apps that ended up with their classes.dex file split across multiple files. Starting with Android 5, Android converts the dex files to oat files to work with the new Android Runtime (ART) on install so multidex is no longer needed. If you increase the minSDK of the app to 21 you shouldn't need the multidex declaration.

[Anke]

@ewpatton

This shouldn't be needed on Android 5 and higher.

When I create an APK with my extension, this line is created in the Mainifest:

<application android: debuggable = "false" android: icon = "@ mipmap / ic_launcher" android: label = "installAPK AI2" android: name = "com.google.appinventor.components.runtime.multidex.MultiDexApplication"

and everything works as it should (on all Android versions) ...

[Boike_Rimba]

Dear Anke,

installAPK_AI2.apk runs normally (download + install) = SUCCESSFUL

Is the version of de.bodymindpower.InstallAPK.aix that I am using compatible (the version shown in the picture)?

BestRegards,
Boike_Rimba

[Anke]

@Boike_Rimba

Is the version of de.bodymindpower.InstallAPK.aix that I am using compatible (the version shown in the picture)?

Yes, but I still need to add a "Download.Completed" event, as @Taifun said:

Extension to download a file to ASD (app-specific directory) without WRITE permission

thank you for your contribution there is only one minor issue... the method DownloadFileToASD is an asynchronous method and usually there should be an event to indicate, that the download has been finished... therefore you might want to replace your method FileDownloadedToASD by that event Thank you Taifun Trying to push the limits!

You have to wait for the download to complete:
