Hello, I have recently tried the Open App block, only that when I export my app, install it and test it, it does not work. What I don’t understand is that it works correctly from Companion but not in my application as such. It just doesn’t do anything. The smartphone I use has Android 11. Could it be that?

Post test apk.

@vknow360 can you add a method to get the app main activity class name
to make the open app from package name work in the code there must be a way to get it
or maybe just a way to read manifest file as string and i can parse it my self

145

@vknow360 can you please look into it i have tested in android studio working below code

import android.content.Context;
import android.content.Intent;

public class test {
    public static String getMainActivityClass(Context context, String pkgName){
        Intent it = context.getPackageManager().getLaunchIntentForPackage(pkgName);
        return it.getComponent().toString();
    }
}

in manifest

<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES" />

    @SimpleFunction(description = "Returns launcher activity for the app")
    public String MainActivityClass(String str) {
        Intent launchIntentForPackage;
        try {
            if (!IsAppInstalled(str) || (launchIntentForPackage = this.context.getPackageManager().getLaunchIntentForPackage(str)) == null) {
                return "ERROR";
            }
            return launchIntentForPackage.getComponent().toString();
        } catch (Exception e) {
            e.printStackTrace();
            return "ERROR";
        }
    }

i my case, i need to generate a file for another automation app to start activity, the class name is needed

for general use, you can start the app with extra which isnt possible with built in launch app block

i dont understand why but the QUERY_ALL_PACKAGES permission is not added in manifest in this extension

it is not dangerous permission do not need to be granted by user it is auto grant at install

without it the app list do nothing on compiled apk

here i have added and everything start working again

also i have found a problem, app icon for most app is 0b, only very few is working, i dont know why, plus it create a mess at asd, should have contained it in a folder

150

using the built in component package utilities the icon is working
built in component save the image in private dir data/data/pkg-name/files/Kodular-App-Icons

Because If you publish your app on Google Play, your app’s use of this permission is subject to approval based on this policy.

i only need the apk so i can use whatever permission i need
i need package name to app label too which isnt available in your extension(i need it before scanning entire list), i have seen it, it do app list async which is very good but i have async extension for other thing anyways

154

Not everyone using this extension requires this permission.

Add QUERY_ALL_PACKAGES permission and it will start working.

155

i added, now the app list can get all app insted of just 5 system app, but the icon still only get a few app, ill try again later
