Android Question Reading unfilter logs into app

[Shay]

Hi

How can I get the unfilter logs into the app?

I tried this without a luck
http://www.b4x.com/android/forum/threads/logcat-in-phone-library.11592/

thanks

Do you want to get the unfiltered logs of your app only?

The general logs are not accessible since Android 4.1.

 

[Shay]

no, all logs
how do I get my own logs?
and is there a way to bypass what you wrote? (why did they blocked it?)
if device is rooted?

 

[Erel]

It is not possible to bypass this limit. It also affects B4A-Bridge: B4A-Bridge and Android 4.1+ logs

I do not know whether it will work with rooted devices.


You can get the logs with the LogCat object. You just need to understand the the event is raised in a different thread.

 

[Shay]

ok, but this is exactly what I don't understand / how to do it

 

[Erel]

Which code you tried to run? What was the problem?

 

[Shay]

the code from:
http://www.b4x.com/android/forum/threads/logcat-in-phone-library.11592/

As you can only read your own app logs, why don't you create a simple LogMessage sub that adds the message to the ListView?

 

[Shay]

what you are saying is starnge since, if I remove the unfilter checkbox from the log tab, I can see all my unfilter logs

 

[Erel]

Are you running Android 4.1+ ?

If yes then you can only read logs of other apps when the device is connected with USB debugging.

 

[Shay]

yes USB, so let's say this is what I want for now
how do I get the logs into the app?

 

[Erel]

You can't read logs of other apps (this is the 5th and last time I write it in this thread).

You wrote:

what you are saying is starnge since, if I remove the unfilter checkbox from the log tab, I can see all my unfilter logs

So I explained that you see the logs in the IDE through the USB connection.

 

[Shay]

but can I get it into my app (add to listview or such)

 

[Erel]

You can use the Threading library (RunOnGuiThread) from the event to delegate the data to the main thread.

 

[Shay]

Erel, but this is the exact issue I asked for help in this thread: (no idea how to do the threading)
http://www.b4x.com/android/forum/threads/logcat-in-phone-library.11592
and you told me to open new thread for it

 

[Erel]

You should read the documentation of this library and if you have any specific question we can help you.

Another option is to explain what you are trying to accomplish. You also didn't write why creating a LogMessage sub that writes to the logs and to your ListView is not a good solution...
