    <p>I am surprised that gnclmorais solution should work. Because it having multiple <code>data</code> entries in one <code>intent-filter</code> did not work for me. What did work in the end was multiple <code>intent-filter</code> in one <code>activity</code>:</p> <pre><code>&lt;activity android:description='@string/Activity_Description' android:icon='@drawable/ic_launcher' android:label='@string/Activity_Name' android:name='net.sourceforge.uiq3.fx603p.Calculator_Activity' &gt; &lt;intent-filter&gt; &lt;action android:name='android.intent.action.MAIN' &gt;&lt;/action&gt; &lt;category android:name='android.intent.category.LAUNCHER' &gt;&lt;/category&gt; &lt;/intent-filter&gt; &lt;intent-filter android:icon='@drawable/ic_fx_603p_pf' android:label='FX-603P Simulator Program' android:priority='1' &gt; &lt;category android:name='android.intent.category.DEFAULT' &gt;&lt;/category&gt; &lt;action android:name='android.intent.action.VIEW' &gt;&lt;/action&gt; &lt;data android:host='*' android:pathPattern='.*\\.pf' android:scheme='file' &gt;&lt;/data&gt; &lt;/intent-filter&gt; &lt;intent-filter android:icon='@drawable/ic_fx_603p_df' android:label='FX-603P Simulator Datafile' android:priority='1' &gt; &lt;category android:name='android.intent.category.DEFAULT' &gt;&lt;/category&gt; &lt;action android:name='android.intent.action.VIEW' &gt;&lt;/action&gt; &lt;data android:host='*' android:pathPattern='.*\\.df' android:scheme='file' &gt;&lt;/data&gt; &lt;/intent-filter&gt; &lt;intent-filter android:icon='@drawable/ic_fx_603p_af' android:label='FX-603P Simulator Allfile (Data and Program)' android:priority='1' &gt; &lt;category android:name='android.intent.category.DEFAULT' &gt;&lt;/category&gt; &lt;action android:name='android.intent.action.VIEW' &gt;&lt;/action&gt; &lt;data android:host='*' android:pathPattern='.*\\.af' android:scheme='file' &gt;&lt;/data&gt; &lt;/intent-filter&gt; &lt;intent-filter android:icon='@drawable/ic_fx_603p_pf' android:label='FX-603P Simulator Program' android:priority='1' &gt; &lt;category android:name='android.intent.category.DEFAULT' &gt;&lt;/category&gt; &lt;action android:name='android.intent.action.VIEW' &gt;&lt;/action&gt; &lt;data android:host='*' android:mimeType='application/x-fx-602p.program' &gt;&lt;/data&gt; &lt;/intent-filter&gt; &lt;intent-filter android:icon='@drawable/ic_fx_603p_df' android:label='FX-603P Simulator Datafile' android:priority='1' &gt; &lt;category android:name='android.intent.category.DEFAULT' &gt;&lt;/category&gt; &lt;action android:name='android.intent.action.VIEW' &gt;&lt;/action&gt; &lt;data android:host='*' android:mimeType='application/x-fx-602p.data' &gt;&lt;/data&gt; &lt;/intent-filter&gt; &lt;intent-filter android:icon='@drawable/ic_fx_603p_af' android:label='FX-603P Simulator Allfile (Data and Program)' android:priority='1' &gt; &lt;category android:name='android.intent.category.DEFAULT' &gt;&lt;/category&gt; &lt;action android:name='android.intent.action.VIEW' &gt;&lt;/action&gt; &lt;data android:host='*' android:mimeType='application/x-fx-602p.all' &gt;&lt;/data&gt; &lt;/intent-filter&gt; &lt;/activity&gt; </code></pre> <p>Note that having both <code>pathPattern</code> and <code>mimeType</code> in one <code>data</code> entry did not work as well. Last not least I would suggest a few null checks when getting the file name:</p> <pre><code> /** * &lt;p&gt;Open calculator and load file (if one was passed).&lt;/p&gt; * @see android.app.Activity#onStart() */ @Override public void onStart () { android.util.Log.d (Calculator_Activity.TAG, "+ onStart"); super.onStart (); final android.content.Intent intent = getIntent (); if (intent != null) { android.util.Log.d (Calculator_Activity.TAG, "&gt; Got intent : " + intent); final android.net.Uri data = intent.getData (); if (data != null) { android.util.Log.d (Calculator_Activity.TAG, "&gt; Got data : " + data); final String filePath = data.getEncodedPath (); android.util.Log.d (Calculator_Activity.TAG, "&gt; Open file : " + filePath); // file loading comes here. } // if } // if android.util.Log.d (Calculator_Activity.TAG, "- onStart"); return; } // onStart </code></pre> <p>The actual loading of the file is missing from the sample. It should be inserted after the “Open file” log command.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
