KivyMD, can't see icons in android but works on linux

I'm just created .apk file with buildozer.But as i said in topic, can't see any icon on device.Everything works and looks fine in Linux. But in device,all icons are blank. This is my buildozer.init requirements: (my ndk,sdk,minapi,ndk_api values are default)
requirements = python3,kivy==1.11.1,https://github.com/kivymd/KivyMD/archive/master.zip
If i use kivymd==0.104.1, i can see icons in android but can't use some commands like : MDTab.get_tab_list() , MDTab.switch_tab() (I asked that problem before in here.So i have to use master branch version because i need to switch MDTabs after some button clicks.But now,i can't see any icon.Is that bug or can someone help me ? Thank you..
(Last note: Im removing .buildozer file before change requirements versions.)

Set correct dependencies in buildozer.spec- https://github.com/kivymd/KivyMD/commit/df73810cc725e4575c93bc4cbbb72f67ff568dc1

Where to find default system icons in Nativescript?

I have created an empty Nativescript application with tns create myApp'. However,app/App_Resources/Android/drawable-hdpi` and other directories does not contain any default system icons. Thus, I cannot use them in the application. How can I find or install default system icons?

However, the default system icons are called using something like this:
<ActionItem ios:systemIcon="12" android:systemIcon="ic_menu_search" tap="showSearch" ios:position="right" android:position="actionBar" />
You can find a list (unfortunately without images) at https://developer.android.com/reference/android/R.drawable.html

For using your custom icons in the application, you have to add them in each drawable-XXX folder and then in your XML src="res://my_icon"
You can find more informations in the official documentation of NS : https://docs.nativescript.org/ui/ui-images#load-images-from-resource

Android Bootstrap not displaying icons in button

I implemented Android Bootstrap library:
https://github.com/Bearded-Hen/Android-Bootstrap
Everything works fine, but icons in buttons are not displayed.
I add font-awesome file into asset folder, but still without successful result.
How can be this solved?
Thanks for any help.

Try what it worked for me, make sure that "android-support-v4.jar" file in libs folder (assuming that you're working in eclipse) is the same copy in AndroidBootstrap library project and your project.
This might only partially solve your problem, you might have problems with the icon not displaying when you change orientation (landscape/portrait) and there might be better solution, but this is my quick fix:
in OnResume add:
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE){
bbYourButton1.setLeftIcon("fa-heart");
bbYourButton2.setRightIcon("fa-twitter");
}

If there is a problem loading the font, you should get the reason in the log cat, as we can see in com / beardedhen / androidbootstrap / BootstrapButton.java at line 343
Log.e("BootstrapButton", "Could not get typeface because " + e.getMessage());
So, go to the logcat and see if you can understand what happened.
Anyways, the better start point is to import the AndroidBootstrapTest project and see if everything works.

Just copy fontawesome-webfont.ttf into assets folder of your project.

Android icon wrong in App Management app, but correct in Launcher

I have a simple Android app (built with Mono for Android), which has a problem with it's icon.
The icon is correct in Launcher and in Task Switcher, but
In Manage Apps and in Task Manager it's displayed a generic Android icon
I've checked the various density resources and the manifest and they all look correct.
(I'm seeing this on a Galaxy S phone and on a Nexus 7)

Most likely you set the icon property for your activities within AndroidManifest.xml, but did not set it for the application.

It occurs to me, that the app icon is somehow being cached in the app manager, so that deinstalling and reinstalling the app does not always change the icon properly. Rebooting the device could help.
Also i found this post very useful: adding application ids in gradle usually solves the problem.

Open "AndroidMenifest.xml" in the Package Explorer and click on the "Application" tab at the bottom. Look at the "icon" field and enter the location for your icon ( Ex: #drawable/iconimage). Next, go into the "AndroidManifest.xml" tab and look for android:icon=, adding the location to that as well (Ex: android:icon="#drawable/iconimage)
Make sure you have the same icon name in both locations!

Oleg and Collin are both right but for completeness - in a Mono app the icon can be set with attributes on the Application object (if you have one):
[Application(Label = "MyAppName", Icon = "#drawable/icon")]
class MyApp: Application
{ ...

Android/PhoneGap debugging: app not updated

I'm trying to use PhoneGap with Android. In the Sample that I run the main app opens an html file:
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
super.loadUrl("file:///android_asset/www/index.html");
}
Now if I change something in the html page, Android always shows the previous content.
Is it possible that the output files (resources in that case) are not updated?
Also if I change the name of the html file in /assets/newName.html and into .loadUrl nothing changes.
Thank you, F.

I'm determined to find a proper answer to this, at the moment changes in the assets dir do not trigger a rebuild.
At the moment I'm slapping a new line in the Activity.java code to force a rebild/deploy..
Will update once I've looked for a real solution.

I see this sometimes when I add a data file to a project in eclipse.
If you think you pkg isnt being updated (re-built) then just rebuild it manually. If your using eclipse just do project->clean and select the project you want to clean. it'll rebuild automatically and include anything that was missed out.

OK Guys found.
The tutorial in the wiki.phonegap.com is obsolete.
Samples instead are updated!
Many thanks.
