Hello, I have try many tutorials/issues whitout succes, but i’have got the same results : java.lang.IllegalArgumentException: File /storage/emulated/0/DCIM/cat.jpg contains a path separator Here is my code : import android.os.Environment; PImage img; void setup() { String path=new String(android.os.Environment.getExternalStoragePublicDirectory(android.os.Environment.DIRECTORY_DCIM).getAbsolutePath()); println(path); img = loadImage(sketchPath(path+"/cat.jpg")); } I think it’s due to api 26 …

SOLVED ! Thx a lot ! There is a builtin function https://android.processing.org/reference/permissions/request.html Here is my code import android.os.Environment; PImage img; File myFile = android.os.Environment.getExternalStoragePublicDirectory(android.os.Environment.DIRECTORY_DCIM); void setup() { requestPermission("android.permission.READ_EXTERNAL_STORAGE", "initRead"); requestPermission("android.permission.WRITE_EXTERNAL_STORAGE", "initWrite"); } void draw() { } void initRead(boolean granted) { if (granted) { println("init read sdcard OK"); String myPath= myFile.toString(); img = loadImage(myPath+"/cat.jpg");/// if needed add subfolders! image(img,0,0); // ... } else { println("Read SDcard is not available"); // ... } } void initWrite(boolean granted) { if (granted) { println("init write sdcard OK"); // ... } else { println("Write SDcard is not available"); // ... } }

@julienrat=== That has nothing to see with API and this error was solved 20 times on this forum: Environment.getExternalStoragePublicDirectory(…) returns a FILE and a file cannot be called “/dossier1/directory2/subfolder4/monfichier.jpg” but only “monfichier.jpg” ! So, as explained in the other posts, instead of your code you have to write: File myFile = Environment.getExternalStoragePublicDirectory(...)); String myPath= myFile.toString(); PImage img = loadImage(myPath+"/monFichier.jpg");/// if needed add subfolders! image(img, 0,0); that s all…If you have got write/read permission on runtime (depending of your API)

Hi ! Many thx for your response ! I have tested your code but results are the same … java.lang.IllegalArgumentException: File /storage/emulated/0/DCIM/cat.jpg contains a path separator import android.os.Environment; File myFile = Environment.getExternalStoragePublicDirectory(android.os.Environment.DIRECTORY_DCIM); String myPath= myFile.toString(); print(myPath); PImage img = loadImage(myPath+"/cat.jpg");/// if needed add subfolders! image(img, 0,0);

@julienrat=== adding permission with the Manifest does not work anymore: you have to ask for permission on run time by code; yet, if you look at your app when it crashes i think that you can see under the crash pop up another one which is “this app is asking permission bla bla”) and (only for testing!) you can (perhaps) acceed to this popup and agree…though it is not at all the good way!

Permissions was set with the processing IDE not directly in manifest file :slight_smile:

No, you have to ask them by code…

Yes i understand now something like your post ? :slight_smile: [image] Porting sketch to Android Studio - Problem with request permission Processing for Android OK, act.requestPermissions( new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 10); works as far as it is now asking for permission. still no file written by Table class. Hm, maybe i got another mistake in my code. testing… thanks a lot act = this.getActivity(); I missed that one.

@julienrat=== exactly! (dont copy/paste without changing my typo new string[])

HI, I am new to developing apps for android phones using processing and am testing the ability to write to, read from external storage like the sd card and came across this post. However the above code with requestPermission(…) method does not seem to work with android phones with versions above android pie (SDK 28), so does not work with SDK 29,30 for example. I get the error: AndroidDevice: cannot find process id, console output will be disabled. followed by: "Read SDcard is not available" "Write SDcard is not available" I tried setting android:targetSdkVersion=“28”/> in the andriodManifest.xml file but this had no effect. I also looked on the android .developer website which seems to indicate that the permissions setting methods for post SDK28 seems to have changed but this just confused me. Is there an updated method for setting permissions to access directories/files etc on external storage using processing? Is there a tutorial related to this? Any help is much appreciated. Cheers.
