Hello. It works on the desktop but does not work on Android. I am using the following code:
try { FileHandle fileHandle = Gdx.files.internal("data.zip"); Gdx.app.log("Assets", "exists = "+fileHandle.exists()+" / "+fileHandle.file().exists()); archive = new ZipFile(fileHandle.file()); } catch (IOException e) { e.printStackTrace(); }and getting an error:
I/Assets: exists = true / false W/System.err: java.io.FileNotFoundException: data.zip: open failed: ENOENT (No such file or directory) at libcore.io.IoBridge.open(IoBridge.java:456) at java.io.RandomAccessFile.<init>(RandomAccessFile.java:117) at java.io.RandomAccessFile.<init>(RandomAccessFile.java:149) at java.util.zip.ZipFile.<init>(ZipFile.java:158) at java.util.zip.ZipFile.<init>(ZipFile.java:119) at com.android.miscellaneous.assets.Assets.getFileResolver(Assets.java:52) at com.android.miscellaneous.assets.Assets.getInstance(Assets.java:35) at com.android.EngineCore.create(EngineCore.java:121) at com.badlogic.gdx.backends.android.AndroidGraphics.onSurfaceChanged(AndroidGraphics.java:311) at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1520) at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1248) Caused by: android.system.ErrnoException: open failed: ENOENT (No such file or directory) at libcore.io.Posix.open(Native Method) at libcore.io.BlockGuardOs.open(BlockGuardOs.java:186) at libcore.io.IoBridge.open(IoBridge.java:442) ... 10 moreHow can I fix this issue?
I think data.zip doesn't exist, "test.zip" is used in the example above.
