我正在构建一个 android 应用程序，在该应用程序中，我使用以下代码拨打*123*1# 之类的 USSD 代码。

context.startActivity(new Intent("android.intent.action.CALL", Uri.parse("tel:*123*1" + Uri.encode("#"))).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));

我面临的问题是我的应用程序正在关闭。请参阅以下日志：

如果是 >= marshmallow，你可以这样尝试

int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE);

    if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(
                this,
                new String[]{Manifest.permission.CALL_PHONE},
                "123");
    } else {
        startActivity(new Intent(Intent.ACTION_CALL).setData(Uri.parse("tel:*123#")));
    }

检查权限

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    switch (requestCode) {

        case 123:
            if ((grantResults.length > 0) && (grantResults[0] == PackageManager.PERMISSION_GRANTED)) {
               startActivity(new Intent(Intent.ACTION_CALL).setData(Uri.parse("tel:*123#")));
            } else {
                Log.d("TAG", "Call Permission Not Granted");
            }
            break;

        default:
            break;
    }
}

并且不要忘记在清单中添加权限

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

对于 < = 棒棒糖设备

试试这个购买调用函数调用（）

public void call() {   
        Intent callIntent = new Intent(Intent.ACTION_CALL);          
        callIntent.setData(Uri.parse("tel:"+phone));          
        startActivity(callIntent);  
}

或者你可以试试这个

 context.startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:*123*1" + Uri.encode("#"))).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));

Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:" + number));
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);

如果您想打开拨号键盘，则无需许可，否则请执行@Nitesh Mishra 提供的上述方法

我猜它与 targetSdkVersion 和使用权限有关。将 targetSdkVersion 更改为 Android 5.1（API 级别 22）或更低版本。它可能会解决问题。
