[jinyistudio]

Hi
How can i lunch b4a_bridge in the android thing with adb command ?

 

[JohnC]

The package name for B4A-Bridge is:

anywheresoftware.b4a.b4abridge

adb shell am start -n com.package.name/com.package.name.ActivityName

The package name for B4A-Bridge is:

anywheresoftware.b4a.b4abridge

adb shell am start -n com.package.name/com.package.name.ActivityName

Can you give me example ? I don't know how to use it.

Can you give me example ?

He already did

I don't know how to use it.

Open a commandline prompt and use adb.

You can NOT use adb from an android app.

adb shell am start -n anywheresoftware.b4a.b4abridge/anywheresoftware.b4a.bridge.ActivityName but always give me "Error: Activity class {anywheresoftware.b4a.b4abridge/anywheresoftware.b4a.bridge.ActivityName} does not exist."

 

[DonManfred]

but always give me "Error: Activity class {anywheresoftware.b4a.b4abridge/anywheresoftware.b4a.bridge.ActivityName} does not exist."

sure. There is no such ActivityName in the Bridge.

try

adb shell am start -n anywheresoftware.b4a.b4abridge/anywheresoftware.b4a.b4abridge.Main

or
adb shell am start -n anywheresoftware.b4a.b4abridge/anywheresoftware.b4a.b4abridge.main

 

[jinyistudio]

main or Main => Error: Activity class {anywheresoftware.b4a.b4abridge/anywheresoftware.b4a.bridge.MAIN} does not exist.

i guess you not install b4a_bridage.apk on your device.

 

[JohnC]

main or Main => Error: Activity class {anywheresoftware.b4a.b4abridge/anywheresoftware.b4a.bridge.MAIN} does not exist.

You forgot to include b4a in Don's second method that had a lower case .main:

adb shell am start -n anywheresoftware.b4a.b4abridge/anywheresoftware.b4a.b4abridge.main

The above works for me.

 

[jinyistudio]

sorry, i type bad word. it is ok. but devices give me "please allow B4A-Bridge to install applications" and B4A cann't connect it. my version is v2.62

 

[DonManfred]

please allow B4A-Bridge to install applications

You are forwared to the settings then. Allow b4bridge in this setting then.....
At least this happens when starting B4ABridge the normal way. B4ABridge does a check and foward the user to the setting where the user need to define the permission manually.

If this does not happen using adb then you need to go to the setting manually and give b4abridge the correct permission (to install a app/apk).

 

[JohnC]

Just curious, why did you want to start the B4A-Bridge app using ADB (in your OP) and not do it manually?

 

[jinyistudio]

I am use android thing first time. because i don't how to use b4abridge like android(just click it). I use android console building this image and i have add b4abridge app and give it full permission. Because it no any icon when i boot it so i don't konw how to lunch b4abridge. I can only start B4ABridge manually with ADB

You shouldn't use B4A-Bridge with Android Things. You need to use ADB. See the tutorial.
