隐式意图无法显示应用程序菜单

Question

我有一个应该调用隐式意图的应用程序，并且我有一个我想要接收意图的目标。它总是打开默认应用程序。我不确定错误在哪里。这是代码：

private void startImplicitActivation() {
    Intent baseIntent = new Intent (Intent.ACTION_VIEW, Uri.parse(URL));
    Intent chooserIntent = Intent.createChooser(baseIntent, CHOOSER_TEXT) ;
    startActivity(chooserIntent);
 }

和

<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="http"/>

logcat

Answer 1

您的<intent-filter>不正确。替换

<data android:mimeType="http"/>

与

<data android:scheme="http"/>

"http" 不是有效的 MIME 类型，而且可能不是您想要的类型。
