Question

我需要通过APK下载来提供应用更新。将已签名的APK下载到设备后，打开它并安装更新后，某些应用功能就会被破坏。

例如，它显示错误的警报。这里调用了showDefaultAlert而不是showWifiAlert

mNetworkTester = new Runnable() {
    @Override
    public void run() {
        NetworkInfo networkInfo = getActiveNetworkInfo();
        if (networkInfo != null) {
            networkType = networkInfo.getType();
        }
        if (!isNetworkAvailable(networkInfo)) {
            if (!mShowingDefaultAlert) {
                if (networkType == ConnectivityManager.TYPE_WIFI) {
                    showWifiAlert(null, null);
                } else {
                    showDefaultAlert(null, null);
                }
                AppCardServer.reset();
                mShowingDefaultAlert = true;
            }
        } else if (mShowingDefaultAlert) {
            if (internetTest != null && internetTest.getStatus().equals(AsyncTask.Status.PENDING)) {
                internetTest.execute();
            } else {
                internetTest = new InternetTestTask(new OnSocketListener() {
                    @Override
                    public void onConnect(boolean connected) {
                        if (connected) {
                            mShowingDefaultAlert = false;
                            showDialog(null);
                            initConfiguration();
                        }
                    }
                });
            }
        }
        handler.postDelayed(mNetworkTester, INTERVAL);
    }
};
handler.post(mNetworkTester);

如果我使用adb install -r安装相同的APK，或者从Android Studio运行它，一切正常。为什么会发生这种情况以及如何解决？

这是我的AndroidManifest

我正在推出像这样下载的apk的安装

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

该应用程序仍处于后台，在安装新的apk并打开应用程序后，某些活动流程失败。这解决了我的问题：

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
finish();

APK更新中断应用功能
