Issue
I'm having some problems with Android Studio at the moment because I recently started using "Vector Assets". I've done absolutely everything necessary to display them correctly in my application (using the app:srcCompat="" in the xml, android {defaultConfig {vectorDrawables.useSupportLibrary true}} in the build.gradle, and AppCompatDelegate.setCompatVectorFromResourcesEnabled(true); in the onCreate() method before setContentView()).
The svg files I imported into Android Studio do not have errors themselves, I can see the result without any problem in an ImageView with the wizard. The only problem comes when I run my application and it arrives at the time to draw the svg. Some of my svg's still work, while others don't, so I think some of them take too long to process. Here is the error :

The most important line, I think, is Caused by: java.lang.IllegalArgumentException: R is not a valid verb. Failure occurred at position 2 of path: STRING_TOO_LARGE.
We also know that this svg was caught in the middle (its size is 187 kilobytes). So I think my SVG file (even imported in Android Studio by "Vector Asset") is too heavy.
As we are told here, the STRING_TOO_LARGE issue appears when the string "is longer than 0x7FFF = 32767 characters". (In the reproduction part)
Indeed, the only svg to work in my application are lighter than 32 kb, which could explain this.
But I really need to display this svg (don't offer to convert it to png!) correctly, and if possible without optimizing its paths. Any help would be welcome!
Solution
I found the answer (at last...).
Actually, there is no real problem with Vector Assets over 32 kb, it all depends on what is in the code. I should have paid more attention to the warnings than usual I don't always look at...
I discovered inside my svg a path data with a path of more than 40kb (in one string so). The fact is that, according to the site in the question, a String can't have more than (about) 32k characters or the whole string used in any xml file will be replaced by "STRING_TOO_LARGE". Anyway, by just removing this line here, I can draw the vector perfectly well (while it is still 250 kb, but now incomplete).
What's quite surprising is that Android Studio only displays a warning (where the string is longer than 32k characters) just to make me understand that an svg with a long path can be slow to display, instead of warning me that the path will be corrupted because it's too long (or even better turn this warning into an error in the IDE, to avoid an unpleasant surprise).
