"am start" doesn't work - Galaxy S6 Edge Q&A, Help & Troubleshooting

This works on every other phone; why not this one? Please help.
adb shell
am start -a android.intent.action.VIEW -d 'https://bing.com/'
Instead of launching a browser, it just shows a "Failed" toast. Nothing in the logs seems pertinent.
Adding stuff to the command, e.g. a package name, doesn't help.
Using a browser manually works fine.

[Q] ls does not sort

When I start the ADB shell from the Windows command line, and type the command "ls", the list of files I get is not sorted by name. Also, if I enter "ls -r" which should reverse sort, I get the error message "no such file". If I type "busybox ls -l", I get the expected sorted list. Also, other commands like "busybox ls -la" work.
My Phone is a Samsung Captivate i897, rooted from Gingerbread with Corn Kernel v7.06 with Superuser and BusyBox installed.
How can I get the Busybox version of the shell commands to run without having to type "busybox" all the time?

[Q] ADB Phone.

In Order to help with this question, I am list the step that are need to recreate the issues
I am create the program:
1. installs an app on the phone
2. runs the app
3. checks the logcat for messages from the app.After I get the right message, I stop the logcat from adb
4. (Only on HTC phone) The Program runs this code:
Code:
adb shell am start -a android.intent.action.MAIN -n com.android.dmportread/.DMPortActivity
that throws HTC CDMA phone in Daig Mode. After Which, I write a number to the NAM
5. After the old phone number is cleared. I wipe the phone by having the PC send this:
Code:
adb shell am start -a android.intent.action.MAIN -n com.android.settings/.MasterClear
This is done by a pc program, I have ADB wrapped up(I am using C#).
After I do the wipe step(Step number 5). That Factory Data Reset screen comes up and goes way with in seconds, and return to the launcher(home screen).
My question....
Why does this happen to the phone? And how to stop it from happen?

[q]reboot tasker

Hi!
I want to stop and start tasker by itself via a bashscript since I see no other way to do so. This works if you put in terminal line by line:
Code:
am force-stop net.dinglisch.android.taskerm
am start -a android.intent.action.MAIN -n net.dinglisch.android.taskerm/net.dinglisch.android.taskerm.Tasker
killall net.dinglisch.android.taskerm
But now I'm stock
My guess was that it would have to work if i put in a file "kst.sh" and run
Code:
sh ./kst.sh
as root. But it doesn't work and it seems to ignore the linebreaks in the file.
So here I am, knowing the commands and need to run them with one call. How do I do that?
Many thanks!!

That error is caused by the windows linebreaks, you need to use any word editor that let you change the linebreak style to Unix (Notepad++ is a popular choice), or write your script from your device directly (any editor for android should work).

'Help' Getting Logcat after Phone Reboot

Hi, I'm just a newbie my phone reboots randomly and I'm trying to find the problem through Logcat so that I could send it though the Devs if its an software bug. I tried adb bugreport but I'm not sure what to look for then it seems that the timestamp starts after the phone reboots. but I couldn't replicate the reboot issue when Logcat is running trough ADB terminal. I've read somewhere its possible to see the "Last_kmsg" but it seems the terminal cannot find it. Any ideas how to narrow the bug report or other ways to get a log? Thank you
*phone is not rooted
*tried factory reset
*tried reinstalling latest software update
EDIT*
I managed to use "Logcat Reader" on android but since that the reboot is unpredictable. I can't save the logs before the reboot. I'm currently looking into other apps maybe theres an autosave incase the phone reboots.
EDIT2*
I was hoping I could get 'dmesg' log but ADB terminal says access denied maybe coz I don't have root access.
@JKD23
To get the booting process events from the logcat
Code:
adb devices
adb shell "logcat –d –b events ^| grep 'boot'" > C:\Android_Logcat_%DATE%_boot.txt
adb shell "logcat -d ^| grep 'preload'" > C:\Android_Logcat_%DATE%_preload.txt

Hi, thanks for replying. I entered those commands in the terminal but all I got was
"grep: 09/13/2020_preload.txt: No such file or directory" for both commands.

How to duplicate what adb does to ad hoc open any given Activity on the Android phone?

I can ad hoc open any given Activity on the Android phone while connected over USB to adb on the Windows PC, but how do I DUPLICATE the SAME THING, but from the phone itself?
For example, how can I run this Activity, ad hoc, on the Android phone?
ACTION: "android.intent.action.MAIN"
PACKAGE: "com.google.android.gms"
CLASS: "com.google.android.gms.ads.settings.AdsSettingsActivity"
Click to expand...
Click to collapse
For illustrative purposes, below is a trivial example of ad hoc opening the "Reset Advertiser ID" Activity on the Android phone.
1. Install & test adb on your PC (I tested this only on Windows 10)
2. Connect your Android device over USB (mine is Samsung, Android 11)
3. Paste this command into a Windows command window:
C:\> adb shell am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity
That's just a trivial example where I can't yet figure out yet how to duplicate that popping up of a given Activity on the android phone for any given Activity, if all I know is the name of that given Activity (and which isn't already found in a static list inside of the shortcut creator apps).
Here are more examples I've tested for other Activities.
Code:
C:\> adb shell am start -n com.android.settings/.Settings
C:\> adb shell am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity
C:\> adb shell am start -n com.google.android.gms/.location.settings.LocationAccuracyActivity
C:\> adb shell am start -n com.android.settings/.applications.ManageApplications
C:\> adb shell am start -n com.google.android.gms/.update.SystemUpdateActivity
C:\> adb shell am start -n com.samsung.android.secsoundpicker/.SecSoundPickerActivity
C:\> adb shell am start -n com.android.settings/.Settings\$NotificationAppListActivity
C:\> adb shell am start -n com.android.settings/.Settings\$AppMemoryUsageActivity
C:\> adb shell am start -n com.android.settings/.Settings\$NotificationAppListActivity
C:\> adb shell am start -n com.android.settings/.Settings\$SecDisabledAppsActivity
C:\> adb shell am start -n com.android.settings/.Settings\$PowerUsageSummaryActivity
C:\> adb shell am start -n com.android.settings/.Settings\$AppAndNotificationDashboardActivity
C:\> adb shell am start -n com.google.android.gms/.app.settings.GoogleSettingsLink
C:\> adb shell am start -n com.google.android.gms/.app.settings.GoogleSettingsIALink
C:\> adb shell am start -n com.google.android.gms/co.g.Space
C:\> adb shell am start -n com.google.android.gms/.gcm.GcmDiagnostics
C:\> adb shell am start -n com.google.android.gms/.nearby.exposurenotification.settings.SettingsActivity
C:\> adb shell am start -n com.google.android.gms/.nearby.sharing.ContactSelectActivity
C:\> adb shell am start -n com.google.android.gms/.mdm.settings.AdmSettingsActivity
C:\> adb shell am start -n com.android.settings/.network.telephony.MobileNetworkActivity
After each command line above you can close the previous results using the adb command shown below (because you can't open an Android Settings Activity on top of an existing Android Settings Activity):
Code:
C:\> adb shell am force-stop com.android.settings
I'm well aware that we can create permanent homescreen shortcuts using shortcut creator applications; but this question is not about creating a homescreen shortcut for permanent access to Android Activities.
This question is how to instantly open ANY given Activity ad hoc (i.e., on a case-by-case basis) on Android whenever you want to - just from the name like we did above using adb (but without needing adb to do it).
Pack all the ADB commands listed in a Linux shell script ( means omitting "adb shell" part ), put this script into /data/local/tmp, make script executable and finally run this script in Terminal Emulator on phone.

That worked! Thank you!
Below is my first testcase, which was the simple example of popping up the "Reset Advertising ID" Activity on Android when all you know is the unique name of the Activity.
This alias (which I named "resetadid") that worked first was:
$ alias resetadid='am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity'
This saves that alias into your bashrc file for safekeeping.
$ alias >> ~/.bashrc
To run that alias at the Android Termux command line, I just type:
$ resetadid
(which will pop up the named Activity on your phone)
Then I put that line into a shell script that I named "resetadid.sh"
$ am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity
And I put the following line into another shell script (named "closegms.sh") to close that gms (google mobile services) Activity.
$ adb shell am force-stop com.google.android.gms
Note for the shell scripts to work, I had to run these commands.
$ pkg install termux-exec
$ termux-fix-shebang ./resetadid.sh
Click to expand...
Click to collapse
This is the "./resetadid.sh" shell script that survives rebooting:
#!/data/data/com.termux/files/usr/bin/bash
am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity
To run that script at the Android Termux command line, I just type:
$ ./resetadid.sh
(that will pop up the named Activity on your phone)
Normally we won't need to close that Activity because resetting the advertising ID will close it when we hit the "reset" and "ok" buttons, but for now we need to close the Activity after we pop it up.
To that end is this temporary "closegms.sh" shell script.
#!/data/data/com.termux/files/usr/bin/bash
adb shell am force-stop com.google.android.gms
There are only two things left.
1. How to put that Termux command in a homescreen icon for free?
2. What to add to that shell script to actually press the "Reset" button?
Anyone know how to add a shell script to the Android homescreen?
Anyone know how to add a command to press the "reset" button?
Typically by long tapping on the home screen, you can create a shortcut to an existing script or add a live folder that contains all of your scripts.
BTW:
Termux is a Terminal Emulator what allows you to run ( Linux conformant ) Android Shell commands / scripts.

Thanks for that advice which works to create, not a shortcut to a script, but a widget to a script (a shortcut would be nicer as it fits in homescreen folders).
It's not as simple as just long tapping because there is a ton of syntax involved, and the files have to be in critical directories, and even the version of Termux matters extremely greatly.
But it does work. Thanks.
So we can now create a homescreen widget that will bring up any given Activity if all we know is the Activity name!
I'll write it up in the next post.

The "right" Termux appears to be that on F-Droid and NOT the one on Google Play as documented elsewhere on the net, this being one link.
For this kind of shell scripts (to run Activities) do you think Andronix will help (Andronis is apparently Linux on top of Android along with Android without the need for rooting).
So we can now create a homescreen widget that will bring up any given Activity if all we know is the Activity name!
For anyone who reads this, may I ask that you please invest five minutes in testing this out and letting everyone here know how it works for you?
What I wrote below is designed so you can just follow the cookbook and you should end up with a widget on your homescreen which will open up to ANY named Activity (but I only give one example below) if all you know is the unique name of that Activity.
Install the F-Droid Termux
(Do not use the Google Play Termux!)
Install the F-Droid Termux:Widget
Start Termux on your Android device
All commands below are run on the Termux command line.
If you had to back out the Google Play Termux in favor of the F-Droid Termux, you'll want to re-create & re-test the alias to a simple Activity such as "Reset Ad ID" as explained earlier in this thread, just to test your syntax.
Re-create:
Code:
alias resetadid='am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity'
Re-test:
Code:
$ resetadid
Then re-create & re-test the shell script we previously described earlier in this thread.
Re-create:
Code:
#!/data/data/com.termux/files/usr/bin/bash
am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity
Re-test:
Code:
$ ./resetadid.sh
Now we're ready to put that command on your homescreen!
Create two directories which are defined in the Termux-Widget help.
Code:
$ mkdir -p $HOME/.shortcuts
$ mkdir -p $HOME/.shortcuts/tasks
Note I'm not sure what the "tasks" directory is for but Termux:Widget docs say to create it.
Move the shell script you created earlier into the $HOME/.shortcuts directory.
Code:
$mv ~/resetadid.sh $HOME/.shortcuts/.
Add the Termux Widget to your homescreen.
Long press your Android homescreen.
Select "Widgets"
Select "Termux:Widget"
Place that "Termux:Widget" on your Android homescreen
Click to expand...
Click to collapse
Depending on your Android version...
It will ask:
"Create widget and allow access?"
To which you press "Yes" to put your widget on the homescreen.
Click to expand...
Click to collapse
To interact with the now-running widget, just press the named entry showing up in that Termux Widget.
Code:
resetadid.sh
Depending on your Android version...
It may ask: "Termux requires "Display over other apps" permission
to start terminal sessions from background on Android >=10."
"Grants it from Settings -> Apps -> Termux -> Advanced" [sic]
Click to expand...
Click to collapse
If needed, grant Termux permission to display over other apps:
Code:
Android11:Settings > Apps > Your apps > Termux > Appear on top = (change off to on)
Now you can press the always running Termux:Widget icon on your homescreen to bring up the desired Activity.
Does this work for you to bring up the named Activity on Android with the only thing you know being the unique Activity name?
If so, here's what's left that I know of:
a. Figure out how to add a step to actually press the "Reset" button!
b. Figure out how to use a shortcut instead of an always-running widget (which can't be placed inside a homescreen folder)
c. Figure out how to run this automatically such as when there is a screen unlocking event.
--
Notes: Keep in mind the goal is to be able to interact with ANY known Android Activity using only freeware (so that everyone can do it); resetting the ad id is just one of the simplest examples.
Interested users can try this on the "Show Running Services" Activity (e.g., for implementing a "ps -aux|kill -9" shortcut).
