【中文标题】在 Android 10 上安装更新同一应用的 apk 失败； java.lang.SecurityException：文件仍然打开【英文标题】：Installing apk that updates the same app fails on Android 10; java.lang.SecurityException: Files still open 【发布时间】：2020-02-10 22:41:36 【问题描述】：我们的应用从我们的服务器下载一个 APK，然后运行它来升级自己。如android 10 - No Activity found to handle Intent 和Xamarin Android 10 Install APK - No Activity found to handle Intent 中所述，如果移动设备已升级到 Android 10，则无法像以前那样工作，得到“未找到处理 Intent 的活动”。
我们已尝试使用 PackageInstaller 重写此内容，如示例中所示 https://android.googlesource.com/platform/development/+/master/samples/ApiDemos/src/com/example/android/apis/content/InstallApkSessionApi.java，但现在得到这个错误：

目标 SDK 设置为 API 23，以便能够支持某些客户拥有的旧设备。我们使用 Qt 作为应用程序框架，但使用 Java 来实现这样的原生 Android 功能。
对此的一些想法： * 在Xamarin Android 10 Install APK - No Activity found to handle Intent 中，他们提到他们需要在 Xamarin 中进行额外的垃圾收集。也许是因为我们这里有同样的问题？如果是这样，我们怎么能直接在 Java 中通过呢？ * 我们正在尝试使用下载的 apk 升级相同的应用程序。使用包安装程序是否可以正常工作？如果没有，我们是否需要使用第二个应用程序来升级原来的应用程序？ * 我们还在应用程序中运行了一个通知服务，这会导致“文件仍然打开”的问题吗？
【问题讨论】：
【参考方案1】：我可以通过关闭 InputStream 和 OutputStream 来解决这个问题。此外，我必须检查 21 之前的 SDK 版本，因为我们有最低 API 16 并且在 API 21 中添加了 PackageInstaller。
public static void JIntentActionInstallApk(final String filename)
PackageInstaller.Session session = null;
try
Log.i(TAG, "JIntentActionInstallApk " + filename);
if(Build.VERSION.SDK_INT < 21)
//as PackageInstaller was added in API 21, let's use the old way of doing it prior to 21
Intent intent = new Intent(Intent.ACTION_INSTALL_PACKAGE);
Uri apkUri = Uri.parse(filename);
Context context = MyAppActivity.getQtActivityInstance().getApplicationContext();
ApplicationInfo appInfo = context.getApplicationInfo();
intent.setData(apkUri);
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, false);
intent.putExtra(Intent.EXTRA_RETURN_RESULT, true);
intent.putExtra(Intent.EXTRA_INSTALLER_PACKAGE_NAME,
appInfo.packageName);
MyAppActivity.getQtActivityInstance().startActivity(intent);
else
// API level 21 or higher, we need to use PackageInstaller
PackageInstaller packageInstaller = MyAppActivity.getQtActivityInstance().getPackageManager().getPackageInstaller();
Log.i(TAG, "JIntentActionInstallApk - got packageInstaller");
PackageInstaller.SessionParams params = new PackageInstaller.SessionParams(
PackageInstaller.SessionParams.MODE_FULL_INSTALL);
Log.i(TAG, "JIntentActionInstallApk - set SessionParams");
int sessionId = packageInstaller.createSession(params);
session = packageInstaller.openSession(sessionId);
Log.i(TAG, "JIntentActionInstallApk - session opened");
// Create an install status receiver.
Context context = MyAppActivity.getQtActivityInstance().getApplicationContext();
addApkToInstallSession(context, filename, session);
Log.i(TAG, "JIntentActionInstallApk - apk added to session");
Intent intent = new Intent(context, MyAppActivity.class);
intent.setAction(MyAppActivity.PACKAGE_INSTALLED_ACTION);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
IntentSender statusReceiver = pendingIntent.getIntentSender();
// Commit the session (this will start the installation workflow).
session.commit(statusReceiver);
Log.i(TAG, "JIntentActionInstallApk - commited");
catch (IOException e)
throw new RuntimeException("Couldn't install package", e);
catch (RuntimeException e)
if (session != null)
session.abandon();
throw e;
private static void addApkToInstallSession(Context context, String filename, PackageInstaller.Session session)
Log.i(TAG, "addApkToInstallSession " + filename);
// It's recommended to pass the file size to openWrite(). Otherwise installation may fail
// if the disk is almost full.
try
OutputStream packageInSession = session.openWrite("package", 0, -1);
InputStream input;
Uri uri = Uri.parse(filename);
input = context.getContentResolver().openInputStream(uri);
if(input != null)
Log.i(TAG, "input.available: " + input.available());
byte[] buffer = new byte[16384];
int n;
while ((n = input.read(buffer)) >= 0)
packageInSession.write(buffer, 0, n);
else
Log.i(TAG, "addApkToInstallSession failed");
throw new IOException ("addApkToInstallSession");
packageInSession.close(); //need to close this stream
input.close(); //need to close this stream
catch (Exception e)
Log.i(TAG, "addApkToInstallSession failed2 " + e.toString());
【讨论】：
传递给 addApkToInstallSession 的文件名是什么？我收到错误 java.io.FileNotFoundException：没有内容提供者：sample.com.sampleandroid.apk。我将文件名作为需要安装的 sample.com.sampleandroid.apk 传递 @manjunathkallannavar：就我而言，文件名是实际文件的完整路径，如下所示：file:///sdcard/temp/myapkfilename.apk 谢谢我能够解析apk路径。现在我的 onNewIntent 方法在 session.commit(statusReceiver) 之后没有被调用。什么时候调用这个方法？ @manjunathkallannavar：如果我没记错的话，onNewIntent 只会在您返回应用程序时调用。例如。启动应用程序后，单击主页，然后再次启动应用程序；如果应用程序已经在运行，则现在调用 onNewIntent。 感谢您的快速回复。我们使用 Cordova 应用程序并在本机中执行应用程序安装代码。我有扩展 Activity 的类，并使用以下代码 context = this.classname ；我无法访问 getPackageManager().getPackageInstaller();使用以下代码的上下文 API context.getPackageManager().getPackageInstaller();我得到空指针异常。 getPackageManager() 以 null 的形式出现。你有什么主意吗 ？谢谢你以上是关于在 Android 10 上安装更新同一应用的 apk 失败； java.lang.SecurityException：文件仍然打开的主要内容，如果未能解决你的问题，请参考以下文章
