带有TaskStackBuilder.addParentStack的Android parentActivityName停止在API 21(Lollipop)上工作 [英] Android parentActivityName with TaskStackBuilder.addParentStack stopped working on API 21 (Lollipop)

问题描述

从小部件打开应用程序时，我正在使用此代码来设置向后堆栈导航.

I'm using this code to setup back stack navigation when opening the app from a widget.

Intent intent = new Intent(context, ComposeActivity.class);

// Create an Intent to launch ComposeActivity

intent.setFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK);

TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);

// Adds the back stack
stackBuilder.addParentStack(ComposeActivity.class);

// Adds the Intent to the top of the stack
stackBuilder.addNextIntent(intent);

// Gets a PendingIntent containing the entire back stack
PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

// Get the layout for the App Widget and attach an on-click listener to the button

RemoteViews recordButtonImageView = new RemoteViews(
  context.getPackageName(), R.layout.record_widget
);

recordButtonImageView.setOnClickPendingIntent(
  R.id.record_button, pendingIntent
);

这是我的AndroidManifest.xml定义

and this is my AndroidManifest.xml definition

<activity
            android:name=".activities.ComposeActivity"
            android:label="@string/compose_activity"
            android:parentActivityName=".activities.MyFeedActivity"
            android:screenOrientation="portrait"
            android:theme="@android:style/Theme.Holo.NoActionBar">

        <meta-data
                android:name="android.support.PARENT_ACTIVITY"
                android:value=".MyFeedActivity"/>

</activity>

对于API 14-20来说效果很好，但对于API 21却没有效果.

it's working great for API 14 - 20 but not for API 21.

我在做什么错了?

推荐答案

我们最近遇到了同样的问题.

We recently came across this very same issue.

这似乎是 com.android.support:support-v4:21.0.+ 中的错误.使用最新发布的版本22，即使cangelog中未提及该更改，它也可以再次工作.

This seems to be a bug in com.android.support:support-v4:21.0.+. Using the recently released version 22 it's working once again, even though the change is not mentioned in the cangelog.
