Sharing CommCare data between apps

[Faizel Faker]

Hi Guys,

I am attempting to create an Android mobile application that can be used to generate and display graphs and charts from CommCare application data stored on the mobile device.

I am trying to query a CommCare app data repository by using an Android ContentResolver.

Here is the code I have written to query the database:

-------------------------------

private static final String REPORT_INSTANCE_ID = "commcare:reports";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    try {
        selectFixture(REPORT_INSTANCE_ID);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

private void selectFixture(String fixtureId) throws Exception {

    String reportXml = getReportXml(fixtureId);
    Document document = getXmlDom(reportXml);
    renderDocumentToGraph(document);
}

private String getReportXml(String fixtureId) {
    ContentResolver cr = getContentResolver();

    Cursor c = cr.query(Uri.parse("content://org.commcare.dalvik.case/fixturedb/" + fixtureId), null, null, null, null);
    if (!c.moveToFirst()) {
        return null;
    }
    return c.getString(c.getColumnIndex("content"));
}

-------------------------------



I am not certain if the Uri I am using is correct but the Uri was recommended by a Dimagi employee. However, the ContentResolver always returns NULL when I perform a query. 

Can anyone advise me on what I am doing wrong or assist me in resolving this issue. 

Thank you

Faizel

Hi Faizel,

According to the wiki at

https://github.com/dimagi/commcare-android/wiki/Accessing-Fixture-Data

The fixture data content provider root is

content://org.commcare.dalvik.fixture/fixturedb/

not

content://org.commcare.dalvik.case/fixturedb/

Can you try that and see if it addresses the issue?
