launcher mode support?

[thewisenerd]

is it possible to have termux as a "launcher" screen?

this angle has been looked at by TUI-ConsoleLauncher ( https://github.com/Andre1299/TUI-ConsoleLauncher ), and I'd think that it would be nice to have an "optional" launcher mode.

a couple of user scripts using the Termux:API add-on and auto complete (volup + T) will make a good launcher.

as for the "launching" apps part, can be either done as a addon extension to Termux:API or cough su am start com.package/.Activity cough some userscripts.

As a T-UI user myself, I've been mulling over this idea for a while.

Turning Termux into a launcher, it turns out, is just a matter of adding a line to the manifest:

diff --git a/app/src/main/AndroidManifest.xml b/app/src/main/AndroidManifest.xml
index aacc244..35cc0d4 100644
--- a/app/src/main/AndroidManifest.xml
+++ b/app/src/main/AndroidManifest.xml
@@ -84,6 +84,7 @@
             <intent-filter>
                 <action android:name="android.intent.action.MAIN"/>
                 <category android:name="android.intent.category.IOT_LAUNCHER"/>
+                <category android:name="android.intent.category.HOME"/>
                 <category android:name="android.intent.category.DEFAULT"/>
             </intent-filter>
         </activity-alias>

So the actual work would be the "activity launching" stuff. Evidently, we can launch activities without root by passing the --user 0 flag to am start: e.g.

$ am start -n org.fdroid.fdroid/.FDroid --user 0

This works pretty well, and In theory we should be able to filter through the list of activities with

$ pm list packages

However, I'm only able to successfully do that via adb. From Termux, it's failing with android.os.DeadObjectException for some reason.

Anyway, we could probably make all this usable with a shell script or two and some bash completion functions.

@xelxebar hi, and thanks for trying this out

pm list packages is crashing because of a selinux denial.

09-10 06:09:12.956  5209  5209 I main    : type=1400 audit(0.0:78): avc: denied { read write } for path="/dev/pts/0" dev="devpts" ino=3 scontext=u:r:system_server:s0 tcontext=u:object_r:untrusted_app_devpts:s0:c512,c768 tclass=chr_file permissive=1

i set my selinux to permissive and it works :smile:

need to figure out a way to fix this :crossed_fingers:

@xelxebar i modified termux to handle a "apps-cache" intent[0] which lists all apps into $HOME/.apps which looks something like this;

FM Radio|com.android.fmradio/.FmMainActivity|com.android.fmradio|true
Camera|org.cyanogenmod.snap/com.android.camera.CameraLauncher|org.cyanogenmod.snap|true
Telegram|org.telegram.messenger/org.telegram.ui.LaunchActivity|org.telegram.messenger|false

coupled with a bash script[1], i can now launch apps :)

@thewisenerd This is an excellent solution :) Thanks!

I am trying to create a run prompt for my device using termux, termux widget and or possibly automate... I am relitively new to "programming/scripting..", and still trying to get a feel for it all. I was wondering if the first file is a modified version of termux apk or a patch? Any resources i could read to helpme impliment it? or any further explaination on how these programs work. I do understand using the am command and can launch apps from termux... its just the rest, you know the hard stuff i need to figure out or just decipher from whats already been done thank you.

Without hacking termux apps , just calling termux activity https://github.com/amsitlab/termuxlauncher

Hi man l am looking for a way to launch an app with termux and I'm a beginner. I think your script mentioned in this can help me with that. But I'm confused. So could you please tell me how to use it ? Thanks in advance

I tried adding tmux as a launcher. Someone posted how to do it. I just can't figure out how to use it as a launcher. He said to use bash... Wasn't very descriptive as I'm new to all this. When I got done running all the scripts tui popped up and says "default. Launcher". I don't know what that means or what I did in termux for Tui to do that.

Any official developments ?

Technically it is possible to add activity-alias to TermuxActivity like it is done in HomeActivity alias for IoT devices. But normally disabled (to not appear as launcher out-of-the-box) with a possibility to enable/disable it from Termux settings (like it is done for FileShareReceiverActivity and FileViewReceiverActivity). In this case we will not break current behaviour.
