I'm using Visual Studio 2017 with the latest update.
I created a new Xamarin Forms solution (.net standard) and when I click on Resource.Designer.cs or when I try to "open with" with many options - I don't get any designer.
Since the text in the file says
// <auto-generated>
// This code was generated by a tool.
// Runtime Version:4.0.30319.42000
//
// Changes to this file may cause incorrect behavior and will be lost if
// the code is regenerated.
// </auto-generated>
Something must be missing.
How do I get the designer working?
According to an answer in the comments this is not like the Visual Studio designer file. It should not be edited, but also does not have a designer mode associated with it.

I'm new to Android-Developement and I would like to make a Camera-app. I found this library (this is the Github page).
But I don't know how to implement a library. I followed these steps (method 2) but I'm getting an error in a popup window called 'IDE Fatal Errors'. It says: 'To investigate / fix the problem IDE wants to attach following files to the bug report. We recommend to include all the files providing maximum information. Note: all the data you send will be kept private.' Then I can select a 'diagnostic.txt'. There is a section 'file content' where 'rootsChanged' is written. I can report the whole window to Google.
The following step is to configure the 'Fotoapparat' instance. What is an instance? When I search on Google I only find articles talking about making a library.
I'm sorry if these are stupid question but I am a beginner and I would like to learn more about Android-Development. Thanks in advance for your time and help.
Add this line in your build.gradle(Module: app) file ->
dependecies {
//Your other dependencies...
implementation 'io.fotoapparat:fotoapparat:2.3.3'
}
And start using your code. Library is working fine.
EDIT - >
You need to learn basics of java.
To setup instance of the object you need to create a variable.
Hence in your case:
Fotoapparat yourVariableName = new FotoapparatFotoapparat
.with(context)
.into(cameraView) // view which will draw the camera preview
.previewScaleType(ScaleType.CenterCrop) // we want the preview to fill the view
.photoResolution(ResolutionSelectorsKt.highestResolution()) // we want to have the biggest photo possible
.lensPosition(LensPositionSelectorsKt.back()) // we want back camera
.focusMode(SelectorsKt.firstAvailable( // (optional) use the first focus mode which is supported by device
FocusModeSelectorsKt. continuousFocusPicture(),
FocusModeSelectorsKt.autoFocus(), // in case if continuous focus is not available on device, auto focus will be used
FocusModeSelectorsKt.fixed() // if even auto focus is not available - fixed focus mode will be used
))
.flash(SelectorsKt.firstAvailable( // (optional) similar to how it is done for focus mode, this time for flash
FlashSelectorsKt.autoRedEye(),
FlashSelectorsKt.autoFlash(),
FlashSelectorsKt.torch()
))
.frameProcessor(myFrameProcessor) // (optional) receives each frame from preview stream
.logger(LoggersKt.loggers( // (optional) we want to log camera events in 2 places at once
LoggersKt.logcat(), // ... in logcat
LoggersKt.fileLogger(this) // ... and to file
))
.build();
And start using yourVariableName.
I have just installed Android Studio on my pc, but I am not able to find any activity or layout file on a creation of a new project.
Here is the screen shot
From the screen-shot it is clear that you haven't created any project yet. Go to file - Click on : New - Click on : New Project.
Now create a project which will get you all the necessary elements like activities, layouts, gradle, etc.
Happy coding.
I developed a simple javafx application to be ported in Android Environment, however I cant type any characters in the TextField. I guess its a bug, how to fix this one?
Th problem on galaxy S5 android 5.0.1 is not present but on galaxy tab 4 android 5.0.2 it doesn't work i type but none is displyed.
Tried with normal textfield. And the problem persist also I have added the properties .
Another strange rhig is that the space where recognizer. And the del button . The text not
THe code by example is very easy
Rectangle2D visualBounds = Screen.getPrimary().getVisualBounds();
double width = visualBounds.getWidth();
double height = visualBounds.getHeight();
TextField tt= new TextField();
tt.setTranslateY(-150);
StackPane stackPane = new StackPane();
stackPane.getChildren().addAll(tt);
borderpane.setCenter(stackPane);
Scene scene = new Scene(borderpane, width, height);
stage.setScene(scene);
Assuming that CustomTextField is just a custom TextField, this is a known issue, not related to the CustomTextField itself, given that it works in other device.
If you debug it:
./adb logcat -v threadtime
you surely find an exception that explains the issue: a StackOverFlow exception.
On older devices it can be solved adding this: create a java.custom.properties file, and include in it this property:
monocle.stackSize=128000
You may also include this one:
monocle.platform=Android
(it will be soon included by default in the next version)
Put the file at the root of your classpath, e.g. in the folder src/android/resources of your project.
Build and deploy the project on your mobile and check again.
I am getting a new problem which may be due to version changes, but I don't know. The exception raised during rendering is as follows:
java.lang.System.array copy([CI[CII)V
Exception details are logged in Window > Show View > Error Log .
The following classes could not be found: - Edit Text (Change to
android.widget.Edit Text, Fix Build Path, Edit XML)
its not getting the class of edit text. From where would I get/add it?
From https://stackoverflow.com/a/24502370/826670. it looks like you are using android Wear to render it, change android version in rendered.
Check the "Android version to use when rendering layouts" and make
sure you're not using a version that ends in "W" for Android Wear
(e.g. API 20: Android 4.4W). I don't believe Wear supports
EditText.
In both Android Studio and Eclipse, it's the dropdown with the green
android in the layout preview's toolbar. You may want to set it
explicitly and not allow the IDE to choose the Android version
automatically.
I'm having trouble getting Eclipse to see that I've just put a new image into my project when referencing that image using R.drawable.this_text
So I drag my png into myProject/res/drawable-hdpi in Eclipse's Project Explorer. The name of the image is this_text and it's a png!
So I go into my application and I want to put this on the screen; So here's the code for that...
private void setTitle()
{
ImageView title = new ImageView(this); //this extends activity
title.setBackgroundResource(R.drawable.this_text);
...
}
This I have done before and each time I do it I experience the same thing:
if i just dragged my this_text.png into the Project Explorer in eclipse, the word "this_text" will be underlined in red, and not allow me to compile or proceed. I try to F5 (refresh) the project. I try refreshing the image foldr, the src, the actual java...etc! I try closing and opening eclipse but nothing really works. So I quit for afew minutes and work elsewhere in my application, and eventually this error goes away!
Well I'm impatient today-- And I'd rather know how to solve this incase I need to do any quick programming! So does anyone know what to do?
I'm using eclipse Version: Indigo Service Release 1.
Thanks- Ethan
R files for android are generated. Rather than refreshing you should be able to CLEAN the project which should fix your issue. You could even just delete the error from the problems list which would allow for compilation to start and for the generated R file to be created. Or you could make a change to an xml which would also allow for the file to be regened. As always make sure you are up to date on your tool chain.
