私は例外に問題がありますNetworkOnMainThreadException。
そのため、関数を asynctask に渡す必要があります。問題は、送信時と受信時ではない 2 つのパラメーターを送信する必要があることです。
これらは送信する必要があるパラメーターであるため、asynctask はそれらを受け取ります。
TypedArray array
Boolean true
public void SetImages(TypedArray array){
SetImages(array, true); // OLD CALL
new task().execute // NEW CALL
}
これは、asynctask に持ち込む必要があるコードです
