我的应用发送USSD请求。它具有一个活动，从该活动启动片段，该片段具有启动AlertDialog的按钮，并且onItemSelected发送USSD请求。现在，当我尝试发送请求并且日志显示上述错误时，强制关闭。

片段的错误点在这里：
startActivity(new Intent("android.intent.action.CALL", Uri.parse("tel :" + ussdCode)));
和AlertDialog：
listener.onItemSelected(MainDialog.this, item, selectedIndex);
任何人都可以帮忙解决这个问题？因为有时它可以随机工作。这行是什么
找不到活动来处理Intent {act = android.intent.action.CALL dat = tel：* 1050 * 100＃}来自日志？
答案 0 :(得分：2)
1。您是否向Manifest添加了<uses-permission android:name="android.permission.CALL_PHONE" />权限？
2. 将代码更改为
Intent intent = new Intent (Intent.ACTION_CALL);
intent.setData (Uri.parse ("tel:" + phoneNumber));
context.startActivity (intent);
3。你可以使用ACTION_DIAL显示拨号号码
答案 1 :(得分：1)
用它来打电话 -
String ussdCode = "*1000*2" + hash;
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:" +ussdCode));
startActivity(intent);
别忘了在Manifest.xml上添加权限 -
<uses-permission android:name="android.permission.CALL_PHONE" />
