Question

嗨我必须在我的应用程序中实现一些调用功能，但是当我选择一个号码进行呼叫时，我的应用程序突然崩溃。

我的代码是：

public void show_alert(String phon) {

            ArrayList<String> phone = new ArrayList<String>();

            if (!phon.equalsIgnoreCase("")) {
                phone.add(phon);
            }

            final CharSequence[] cs = phone.toArray(new CharSequence[phone.size()]);

            AlertDialog.Builder builder = new AlertDialog.Builder(Contact.this);

            builder.setPositiveButton("Cancel", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();

                }
            });
            builder.setTitle("Would You Like to Call ");
            builder.setItems(cs, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int item) {

                    call(Contact.this, cs[item].toString());

                }
            }).show();
        }

        public void call(Context ctx, String number) {
            try {
                Intent callIntent = new Intent(Intent.ACTION_CALL);
                callIntent.setData(Uri.parse("tel:" + number));
                ctx.startActivity(callIntent);
            } catch (ActivityNotFoundException activityException) {
                Log.e("helloandroid dialing example", "Call failed",
                        activityException);
            }
        }

我不知道我的代码有什么问题。请有人帮助我。

logcat的：

Answer 1

您应该使用Intent.ACTION_DIAL代替Intent.ACTION_CALL。它将调出电话拨号器，就像其他应用程序的行为一样（相同的用户体验）

Answer 2

您是否提供了CALL权限？

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

Answer 3

你的logcat清楚地说：

3-20 15:47:12.771: E/AndroidRuntime(29736): java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.CALL dat=tel:xxxxxxxxxxxxx cmp=com.android.phone/.OutgoingCallBroadcaster } from ProcessRecord{422a3f38 29736:com.universaltyres/10075} (pid=29736, uid=10075) requires android.permission.CALL_PHONE

您需要在manifest.xml文件中添加以下权限

<uses-permission android:name="android.permission.CALL_PHONE" />

当我选择打电话时，应用程序崩溃了
