Get Texture from Unity in Android

Good morning.

I want to use the Android plug-in to save the image to Internal Storage and import the image from Internal Storage.

When you save an image in Unity, the user can access the saved image.
I do not want users to access stored images.
So I tried to create and use Android plugin, but it is not working properly.

I need help.

Android Native Code :

public void WriteToInternalStorage(String name, byte data)
try
FileOutputStream fileOutputStream = context.openFileOutput(name, context.MODE_PRIVATE);
fileOutputStream.write(data);
fileOutputStream.close();
catch(IOException e)
e.printStackTrace();



public byte ReadToInternalStorage(String name)
StringBuffer stringBuffer = new StringBuffer("");
byte buffer = new byte[1024];
int n;
try
FileInputStream fileInputStream = context.openFileInput(name);
InputStreamReader inputStreamReader = new InputStreamReader(fileInputStream, "UTF-8");
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String line;
while((line = bufferedReader.readLine()) != null)
stringBuffer.append(line);


catch (IOException e)
e.printStackTrace();


return String.valueOf(stringBuffer).getBytes();



Unity Code :

public void NativeCall_ReadInternalStorage(string name)

byte test = instance.Call<byte>("ReadToInternalStorage", name);

Texture2D tex = new Texture2D(2, 2);
tex.LoadImage(test);
Thumbnail.texture = tex;



The image is not displayed properly.
I do not know what's wrong with the Android native code.

Please help me.

BufferedReader.readLine

InputStream

Texture2D.LoadImage
