Question

我只看到了第33号新闻稿。是否有变化?

我有两点:A和B。请打电话com.example.a和com.example.b。它们必须相互发射。至2008年12月31日,在A组试图发射B时,我收到:

android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.b/com.example.b.DefaultLaunchActivity}; have you declared this activity in your AndroidManifest.xml, or does your intent not match its declared <intent-filter>?

DefaultLaunchActivity is defined in app B s manifest like this:

<activity
    android:name="com.example.b.DefaultLaunchActivity"
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

我在《意向书》中还补充了以下内容(参见第31段):

<queries>
    <package android:name="com.example.b" />
</queries>

最后,附录 a. 类似于B的发射:

val intent = application.packageManager.getLaunchIntentForPackage("com.example.b")?.apply {
    addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
    addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
    addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP)
}

Adding Intent.FLAG_ACTIVITY_REQUIRE_NON_BROWSER doesn t help. App B gets the same error when it tries to launch app A.

明确, 以上编码是关于APIC32的,但并非第55/233号。发生了什么变化?

Answer 1

Yes, many things have changed.

页: 1 如:

    <queries>
        <package android:name="com.google.android.apps.translate"/>
    </queries>

It was introduced in Android 11 (API 30). The observed behavior might be explained as it was introduced in API 30, but forced since API 33. Also others causes are possible. It will require more research to figure out a root cause.

Ref. Android docs: Behavior changes: Apps targeting Android 11

update I noticed you already use queries attribute, so an issue cause lays somewhere else
