PackageInstaller 完成（自我）更新后启动应用程序

PackageInstaller 成功（自行）更新应用程序后，应用程序将关闭并且不会再次启动。

可能重复：Android PackageInstaller，更新后重新打开应用程序 https://stackoverflow.com/questions/43940990/android-packageinstaller-re-open-the-app-after-it-updates-itself

情况非常相似，我先展示一些代码片段。

AndroidManifest.xml

<receiver android:name=".UpdateReceiver" >
    <intent-filter>
        <action android:name="android.intent.action.MY_PACKAGE_REPLACED" />
    </intent-filter>
</receiver>

我的 PackageInstaller 会话在 AsyncTask 中运行：

PackageInstaller packageInstaller = ctx.getPackageManager().getPackageInstaller();
        PackageInstaller.SessionParams parameters = new PackageInstaller.SessionParams(
                PackageInstaller.SessionParams.MODE_FULL_INSTALL);
        parameters.setAppPackageName(StaticData.TerminalPackageName);

        progressChanged(10);

        try {
            int sessionId = packageInstaller.createSession(parameters);
            PackageInstaller.Session session = packageInstaller.openSession(sessionId);

            ProgressApproximatorHandler progress = startProgressApproximator(10, 100, 5);

            OutputStream installerStream = session.openWrite("INSTALL_TERMINAL", 0, mApplicationLength);
            installerStream.write(firmwareData, 0, mApplicationLength);

            // This call ensures every byte on the stream is committed to disk.
            session.fsync(installerStream);
            installerStream.close();

            Intent intent = new Intent(ctx, UpdateReceiver.class);
            intent.setAction(Intents.APK_INSTALL_FINISHED_INTENT);
            PendingIntent pendingIntent = PendingIntent.getBroadcast(
                    mContext.get(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

            // Sealing the session.
            session.commit(pendingIntent.getIntentSender());
            session.close();
            progress.stop();

        } catch (IOException e) {
            Logger.error(mLogTag, e, "Failed to create an installer session.");
            return false;
        }

在此代码段的末尾，您可以看到要发送的意图的设置。我尝试了很多变体，但没有一个有效。例如：

Intent intent = new Intent(Intents.APK_INSTALL_FINISHED_INTENT);

and

Intent intent = new Intent("android.intent.action.MY_PACKAGE_REPLACED");

我的接收者从未收到意图。

public class UpdateReceiver extends BroadcastReceiver {
    private static final String TAG = "UPDATE";
    @Override
    public void onReceive(Context context, Intent intent) {
        Logger.info(TAG, "Intent action: " + intent.getAction());
        Logger.info(TAG, "updated");
    }
}

编辑：不知何故，我设法自动重新启动应用程序，但它在 1-3 秒后被杀死。我在系统的logcat中发现如下错误。

我不确定这是否是原因。

EDIT2：现在我收到了意图，因此应用程序正在运行。现在的问题是它在后台堆栈中。

我有一个启动器应用程序could重新启动主（更新）应用程序，但这对我来说听起来不是干净的代码。

EDIT3:

我尝试了大卫的回答，但收到以下错误：

请注意，这是由 android 系统抛出的，而不是由我的应用程序抛出的。

The MY_PACKAGE_REPLACED Intent在您的应用程序更新后由 Android 广播。

要在更新后重新启动应用程序，您可以通过启动Intent to the PackageInstaller， 像这样：

Intent intent = getPackageManager().getLaunchIntentForPackage("my.package.name");
PendingIntent pendingIntent = PendingIntent.getActivity(
                mContext.get(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
session.commit(pendingIntent.getIntentSender());

这应该会导致您的应用程序在更新完成后重新启动。
