所以,我的 Activity 中有这段代码(布局支持触发方法的按钮的用户界面onSaveRegistrationClick
):
public void onSaveRegistrationClick (View view){
postData();
}
public void postData(){
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.mywebsite.com");
try
{
httpclient.execute(httppost);
} catch (Exception e){
Toast.makeText(this, "Not working" , Toast.LENGTH_SHORT).show();
}
}
在我的网站上,我有 index.php,它在调用时会在数据库中保存一行,这有助于我确定 Android 是否连接到站点。但是,我在网上遇到了例外情况httpclient.execute(httppost);
。我错在哪里?
PS - 我在 AndroidManifest.xml 中添加了权限(我添加了额外的权限,即:
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
