Image Uri to bytesarray
android, arrays, uri
Solution
From `Uri` to get `byte[]` I do the following things,
InputStream iStream = getContentResolver().openInputStream(uri);
byte[] inputData = getBytes(iStream);
and the `getBytes(InputStream)` method is:
public byte[] getBytes(InputStream inputStream) throws IOException {
ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();
int bufferSize = 1024;
byte[] buffer = new byte[bufferSize];
int len = 0;
while ((len = inputStream.read(buffer)) != -1) {
byteBuffer.write(buffer, 0, len);
}
return byteBuffer.toByteArray();
}
Problem
I currently have two activities. One for pulling the image from the SD card and one for Bluetooth connection. I have utilized a Bundle to transfer the Uri of the image from activity 1. Now what i wish to do is get that Uri in the Bluetooth activity to and convert it into a transmittable state via Byte Arrays i have seen some examples but i can't seem to get them to work for my code!! ``` Bundle goTobluetooth = getIntent().getExtras(); test = goTobluetooth.getString("ImageUri"); ``` is what i have to pull it across. What would be the next step?
