ANDROID - Intent to launch app as a file manager

Question

I am building an app using Phonegap Build. HTML,CSS,JS...

I want the app to come up when the user clicks something that needs a file manager.

I know, I have to put something in the AndroidManifest, but I have no idea what... Any help?

Another Example: Let's say i am on my home screen (APEX) and want to select a new icon. When I click the icon a list comes up with all the apps I can use to find the icon. These apps include Astro, Box, SolidExplorer, Gallery, and more... How can I get my app to come up on that list?

Answer 1

You need to declare your activity in manifest file with such intent-filter with specific data elements.

for ex:

  <intent-filter> 
    <action android:name="android.intent.action.VIEW" /> 
    <category android:name="android.intent.category.DEFAULT" /> 
    <data android:scheme="file" /> 
    <data android:host="*" /> 
    <data android:pathPattern=".*\\.pdf" /> 
  </intent-filter> 

Answer 2

Intent.ACTION_GET_CONTENT may help.

Here is an example of launching a file chooser with image type files.

Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("image/*"); // choose any image
intent.addCategory(Intent.CATEGORY_OPENABLE);
Intent chooserIntent = Intent.createChooser(intent, "File chooser");
startActivityForResult(chooserIntent, REQUEST_CODE);
