我幾乎完成了我的應用程序,即時通訊上的菜單項工作現在, 的問題是設置一個位圖作爲牆紙和保存它從菜單項SD卡。位圖:在SD卡設置壁紙和保存在菜單項
我想的東西,第一個是創造它正在採取從以前的活動-again-同樣的數據的意圖,-I有失敗 -
用同樣的意圖第二-i已經失敗 -
這是我的代碼。
謝謝

@Override
public boolean onCreateOptionsMenu(Menu menu) {

public Object fetch(String address) throws MalformedURLException,
IOException {

我不知道是你有困難哪方面,如果只是下載您可以創建從InputStream您製作繪製對象時創建一個新的文件並將其保存到所需的位置後,將圖像保存。 – kabuto178
