Android Question Installation and working of Base app for new user to rapid build app

[sivakrith]

Hello,

I'm new to B4A. Just learning this. After finishing B4X Getting Started Booklet, I found this thread

Base app for new user to rapid build app

Update 29/8/2018: i uploaded new version without FIREBASE to help who dont need B4A is very good app to build Android app. I want to use it built app same as Android Studio, so i make a "BASE" app to make more apps from it Since 8/2018, you must set target SDK is 26, so many changes to your...

www.b4x.com

I downloaded < with Firebase option> , copied it to a folder, opened it.

1. added required libraries < anything missing? >

2. Modified these lines, by removing one parameter < before the last one>
clvmenu.Add(CreateListItem("home.png","Home",False, clvmenu.AsView.Width, 50dip), "Home")
clvmenu.Add(CreateListItem("search.png","Search",False, clvmenu.AsView.Width, 50dip), "Search")
clvmenu.Add(CreateListItem("","",True, clvmenu.AsView.Width, 50dip), "")
clvmenu.Add(CreateListItem("review.png","Rate",False, clvmenu.AsView.Width, 50dip), "Rate")
clvmenu.Add(CreateListItem("play-store.png","More Apps",False, clvmenu.AsView.Width, 50dip), "More Apps")
clvmenu.Add(CreateListItem("","",True, clvmenu.AsView.Width, 50dip), "")
clvmenu.Add(CreateListItem("logout.png","Exit",False, clvmenu.AsView.Width, 50dip), "Exit")

3. Added : in Sub Process_Globals
Private xui As XUI

4. Modified the line, by commenting
'Msgbox("This app needs write data to your phone. Without this permission, this app cant work! Please 'Allow' to continue","Allow app to save file")
To
xui.MsgboxAsync("This app needs write data to your phone. Without this permission, this app cant work! Please 'Allow' to continue","Allow app to save file")

5. Created and downloaded google-services.json

6. Modified Build configurations to match the package name as done in google-services

7. Modified the android targetSDKVersion to 28 <not sure whether this is a must >


Result: No error shown but the app crashes in the mobile <debug mode>

What could be the reason ?

Post the logs.

 

[sivakrith]

Will it create logs ? Where the log file available ?

[sivakrith]

Nothing. Just blank.

Click on connect to connect your device...

 

[sivakrith]

The device is connected. < checked by running other apps >
When I run <F5>, IDE connects, copy, installs the apps. It asks for Open finally. When I click Open, it just closes, with NO LOG messages.
When I try to run the apps from mobile, <ICON appears in mobile>, I get the following message.

base_app_demo keeps stopping
App Info
Close app

Again no messages in the LOG. Just blank. Still the device is connected <B4A-Bridge is running and the status shows connected, both in IDE as well as in device>

 

[sivakrith]

Tried with Log statement in Sub Activity_Create as the first line. No output.

Are you running in release mode? If so then there should be a single line comment in the log recommending you to add #Bridgelogger: True to the Project Attributes.

 

[sivakrith]

No. Not in Release mode, In Debug mode only.

 

[agraham]

Is this a Huawei device?

 

[sivakrith]

Not Huawei. I tried with Asus Z01RD and Lenovo Tab.

 

[sivakrith]

When I tried with that app <without Firebase option>, I get the following error message in log screen.

Error occurred on line 71 (Main)
java.lang.RuntimeExecption: java.lang.ClassNotFoundException: b4a.example.baseapp.customlistview
at anywheresoftware.b4a.keywords.LayoutBuilder.loadLayout(LayoutBuilder.java:170)
.....

This is the line
lftMenu.LoadLayout("Left")

Will it be useful in diagnosing the error ?

 

[sivakrith]

Something with SlidingMenu ?

Private sm As SlidingMenu

May be some issues in installing that particular library ? I think I've installed the latest one. Hope it will work fine with B4A 10.

slider menu use this:

[B4X] B4XDrawer - sliding drawer

Edit: Cross platform example based on B4XPages https://www.b4x.com/android/forum/threads/b4x-b4xpages-b4xdrawer.120246/ A class that implements a sliding menu. Unlike the nice jfeinstein SlidingMenu library the drawer covers the activity instead of pushing it. It is similar to the various...
