在PackageInstaller完成(自我)更新后启动应用程序

Question

在PackageInstaller成功(self)更新应用程序后，应用程序将关闭，不会再次启动。

可能重复：Android PackageInstaller, re-open the app after it updates itself

情况非常相似，我会先显示一些代码片段。

AndroidManifest.xml

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

我的PackageInstaller会话运行在一个AsyncTask中：

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;
        }

在这个片段的末尾，您可以看到发送意图的设置。我试过很多种变体，但都没有用。例如：

Intent intent = new Intent(Intents.APK_INSTALL_FINISHED_INTENT);

和

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

我的收信人从来没有收到过这个意图。

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:不知怎么的，我设法自动重启了这个应用程序，但是它在1-3秒后就被杀死了。我在系统的logcat中发现了以下错误。

我不知道这是否是原因。

EDIT2:现在我收到了这个意图，所以这个应用程序正在运行。现在的问题是它在后面的堆栈中。

我有一个启动程序，可以重新启动主(更新)应用程序，但这听起来不干净的代码。

我尝试了David的回答，但是我收到了以下错误：

注意，这是android系统抛出的，而不是我的应用程序。

Answer 1

MY_PACKAGE_REPLACED Intent在你的应用程序更新后由安卓进行广播。

要在更新后重新启动应用程序，可以将启动Intent传递给PackageInstaller，如下所示：

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

这将导致您的应用程序在更新完成后重新启动。

而大卫·瓦赛尔的答案可能是正确的。我结束我的案子是因为我有非常奇怪和不明确的行为，而且我很确定这是因为我使用的是一个自定义ROM
