Android: android.content.ActivityNotFoundException: No Activ

Question

我收到这个错误;

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.PICK cat=[android.intent.category.OPENABLE] dat=content://media/external/audio/media }

代码;

public void openMedia(){
Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Audio.Media.EXTERNAL_CONTENT_URI).addCategory(Intent.CATEGORY_OPENABLE);
startActivityForResult(intent, PICK_MEDIA);
}

清单;

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/Theme.BasicMediaPlayer">
<activity
android:name=".MainActivity"
android:exported="true"
android:label="@string/title_activity_main"
android:theme="@style/Theme.BasicMediaPlayer.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

我试图改变意图行动和活动结构，但无法解决我的问题。我试图使用意图让用户从存储中选择一个文件。

Answer 1

已解决。

我仍然不知道为什么我得到这个错误，但我这样做了;

1. 添加<category android:name="android.intent.category.LEANBACK_LAUNCHER" />线到intent-filter.
2. 我正在使用Android电视模拟器(API 28)并将其更改为API提拉米苏。

可能是android api的问题。
