I am trying to read the content from a cursor like so:

cursor = context.getContentResolver().query(TASKS_URI, null, null, new String[]{"-1", "true"}, null);

Where the TASKS_URI is:

private final static Uri TASKS_URI = Uri.parse("content://org.dayup.gtask.data/tasks");

So all i am trying to do is to get a cursor from another app.

In my manifest.xml i define my permission as:

   <uses-permission android:name="org.dayup.gtask.permission.READ_TASKS"/>

The problem is that if my app was installed before the other app (in this case gtask) i get the following error:

05-08 15:26:45.380: ERROR/ActivityThread(18564): Failed to find provider info for org.dayup.gtask.key

If i reinstall my app or my app was installed after the other apps everything works fine.
Any idea on how to reacquire these permissions on runtime ?

    There is a workaround for this.
    The trick is to define the permissions as if they were your own.

    Here is an example:

    <uses-permission android:name="com.timsu.astrid.permission.READ_TASKS" />
<permission android:name="com.timsu.astrid.permission.READ_TASKS"
    android:permissionGroup="android.permission-group.PERSONAL_INFO"
    android:protectionLevel="dangerous" android:label="read astrid tasks data" />
<uses-permission android:name="android.permission.CHANGE_COMPONENT_ENABLED_STATE" />
<!-- dato gtask -->
<uses-permission android:name="org.dayup.gtask.permission.READ_TASKS" />
<permission android:name="org.dayup.gtask.permission.READ_TASKS"
    android:permissionGroup="android.permission-group.PERSONAL_INFO"
    android:protectionLevel="dangerous" android:label="read dato gtasks tasks data" />
