实现eSIM，LPA实例

Question

我试图使用文档eSim中的示例编写在设备上实现https://source.android.com/devices/tech/connect/esim-overview?hl=en的代码测试示例。该设备支持eSim，验证方法mgr.isEnabled()返回true。但是，当我试图调用公共加载方法downloadSubscription时，不会调用onReceive方法。

static final String ACTION_DOWNLOAD_SUBSCRIPTION = "download_subscription";
static final String LPA_DECLARED_PERMISSION
    = "com.your.company.lpa.permission.BROADCAST";
BroadcastReceiver receiver =
        new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                if (!action.equals(intent.getAction())) {
                    return;
                }
                resultCode = getResultCode();
                detailedCode = intent.getIntExtra(
                    EuiccManager.EXTRA_EMBEDDED_SUBSCRIPTION_DETAILED_CODE,
                    0 /* defaultValue*/);
                resultIntent = intent;
            }
        };
context.registerReceiver(receiver,
        new IntentFilter(ACTION_DOWNLOAD_SUBSCRIPTION),
        LPA_DECLARED_PERMISSION /* broadcastPermission*/,
        null /* handler */);

// Download subscription asynchronously.
DownloadableSubscription sub = DownloadableSubscription
        .forActivationCode(code /* encodedActivationCode*/);
Intent intent = new Intent(action);
PendingIntent callbackIntent = PendingIntent.getBroadcast(
        getContext(), 0 /* requestCode */, intent,
        PendingIntent.FLAG_UPDATE_CURRENT);
mgr.downloadSubscription(sub, true /* switchAfterDownload */,
        callbackIntent);

我不太明白到底需要在这里指定什么，"com.your.company.lpa.permission.BROADCAST"，我试着把"com.your.company“改为包名，但是它不起作用

我正面临着和你一样的问题，真正解决问题的是：

当您创建这样一个新的意图时，将作为参数传递给PendingIntent：

Intent intent = new Intent(action);

动作值应该与ACTION_DOWNLOAD_SUBSCRIPTION相同，我在它们上传递了不同的值，您不需要设置LPA_DECLARED_PERMISSION，您可以将null传递给registerBroadcast。
