While trying to save an image I am getting the error message 'Unresolved reference:runOnUiThread' and also on the context terms inside the toast messages. The relevant code snippets are as below. I have tried all possible fixes, but failed. Please help!
private suspend fun saveDrawnView(myBitmap: Bitmap): String {
var result = ""
withContext(Dispatchers.IO) {
if (myBitmap != null) {
try {
val bytes = ByteArrayOutputStream()
myBitmap.compress(Bitmap.CompressFormat.PNG, 90, bytes)
// val externalCacheDir = null
val f = File(
getExternalStorageDirectory()?.absolutePath.toString() +
File.separator + "com.example.drawingboardforkids" + System.currentTimeMillis() / 1000 + ".PNG"
)
val fo = FileOutputStream(f)
fo.write(bytes.toByteArray())
fo.close()
result = f.absolutePath
runOnUiThread{
if (!result.isEmpty()) {
Toast.makeText(
this@MainActivity,
"File saved successfully :$result",
Toast.LENGTH_SHORT
).show()
} else {
Toast.makeText(
this@MainActivity,
"Something went wrong while saving the file.",
Toast.LENGTH_SHORT
).show()
}
}
} catch (e: Exception) {
result = ""
e.printStackTrace()
}
}
}
return result
}
}
I've checked the coroutine dependencies inside build gradle, went throught clean, rebuild, invalidate caches, restart the pc etc., but the problem persists and hence the query. Please help!
