QUESTION

Unable to get EGL14.eglGetCurrentContext() in Unity

Asked 2021-Apr-13 at 11:18

As per the tittle, I am unable to get the EGL14.eglGetCurrentContext() inside an Android Java class. More precisely, the returned context is equal to EGL14.EGL_NO_CONTEXT.

My interpretation is that the code is called from the main Unity thread yet the code is not able to get the OpenGL context.

Multithreaded rendering is disabled. The project is a Unity project exported to Android. This C# code calls the Java initSurface method from an Update function of a MonoBehavior:

It was occurring because Unity was using Vulkan instead of OpenGLES all along. Disabling the Automatic Graphics API in the Player settings and dragging OpenGLES2 on top fixes the issue.

QUESTION

String limit on android studio

Asked 2021-Feb-20 at 10:54

i am really new to Android Studio and java programming.

im trying to create a new project, just to experimenting and learning.

this app there is long text and i using string to format it and also as resources.

however, after 1400+ text and formatting, the activity crash.

may i know is there some limit on string resources ?

and what is the way to overcome the problems ?

i figured out to use raw text, but on my current understanding, there is no way to format it like strings.

really appreciate if anyone can help.

String.length() method returns the length of the string. The length of the string is equal to the number of Unicode units in the string. The Java platform uses the UTF-16 representation in char arrays (each character takes two bytes), String, and StringBuffer classes.

The method returns the length which is of type int. So, the String maximum size is the same as the range of integer data type. The maximum length that would be returned by the method would be Integer.MAX_VALUE.

The size of int in Java is 4 bytes (included a signed bit, i.e. MSB). The range of integer data type is -2³¹ to 2³¹-1 (-2147483648 to 2147483647). Remember that we cannot use negative values for indexing. The indexing is done within the maximum range. It means that we cannot store the 2147483648th character. Therefore, the maximum length of String in Java is 0 to 2147483647. So, we can have a String with the length of 2,147,483,647 characters, theoretically.

No, they can't. CompUnits, compilation units or installed modules are immutable. You cannot unload a module to load it again, which is what you mean by hotfix.

QUESTION

Dynamic load of object file to execute

Asked 2017-Nov-02 at 10:41

I was wondering what are the steps to load an object file (generated from a single source file by the the msvc compiler), load it in memory of my program already running (in a buffer for example) and then run the code inside it.

The use case is that I have a large program which take a minute to load and wanted to do real time modifications from source code. Like just load the object file, fix some addresses in this object file, use the -hotpatch function to intercept call in my already running process and redirect to my object file.

Seems to me that I should just resolve the import table of the object file to point to my already loaded programs and intercept the call of the functions which have been modified.

Am I missing something ? I would like to ask before trying it to not waste time on something that may be impossible !

Thanks !

To answer the direct question (about loading and executing an obj file): this essentially amounts to re-writing a linker. Which is all but impossible.

As for (what I can figure out of) your intended usage: dynamically loading and executing an obj file wouldn't get you any closer to intercepting calls in your already running process. What you want is probably hooking. There are a lot (no, seriously, a lot) of ways to do so. Detours is the more-or-less official way to achieve this, here's a presentation of a few ways from the exotic side of the spectrum.
