Question

I am creating an mp3tag editor and want it to get started via the android-buildin-filebrowser “myfiles” (com.sec.android.app.myfiles/com.sec.android.app.myfiles.MainActivity) .

When i select a mp3 file i get an activity chooser that offers me two programs to execute the file.
Unfortunately my own program is not among the offered choises.

However if i use the external android-filebrowser OI File Manager it offers me a chooser
which includes my own app.

My question: how do i have to register my actrivity in the manifest so that “myfiles” can launch it?

My app is registered like this:

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="media.mp3"
        android:versionCode="1"
        android:versionName="1.0" >

        <uses-sdk android:minSdkVersion="7" />

        <application
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name" >
            <activity
                android:label="@string/app_name"
                android:name=".Mp3TagEditorActivity" >
                <intent-filter >
                    <action android:name="android.intent.action.MAIN" />

                    <category android:name="android.intent.category.LAUNCHER" />
                    <category android:name="android.intent.category.EDIT" />
                    <category android:name="android.intent.category.VIEW" />
                    <data android:mimeType="audio/mpeg"  />

                </intent-filter>
            </activity>
        </application>
    </manifest>

There is no “android-buildin-filebrowser ‘myfiles'” in the Android OS. You may be thinking of a file browser that ships on some specific device.

My question: how do i have to register my actrivity in the manifest so that “myfiles” can launch it?

To answer that definitively, you would have to contact the author of “myfiles”.

My app is registered like this:

Your <intent-filter> is rather wrong.

First, EDIT and VIEW are actions, not categories.

Second, the only way it will match on your <intent-filter> is if the LAUNCHER category is included, which is very unlikely for the EDIT or VIEW actions.

If you want this activity to both be in the home screen’s launcher and respond to VIEW or EDIT actions, you would need something like this:

        <activity
            android:label="@string/app_name"
            android:name=".Mp3TagEditorActivity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <intent-filter >
                <action android:name="android.intent.action.EDIT" />
                <action android:name="android.intent.action.VIEW" />
                <data android:mimeType="audio/mpeg"  />
            </intent-filter>
        </activity>

Two separate <intent-filter> elements are a logical OR — any Intent that matches the first or the second will match this activity.
