Question

I have one app with a ContentProvider:

    <provider android:name="ExampleProvider" 
              android:readPermission="example.contentprovider.READ"
              android:label="Example Content Provider"
              android:authorities="example.contentprovider.provider"
    />

and another app requests permission to access the provider:

<uses-permission android:name="example.contentprovider.READ" />

But when I run the second app, I get

E/AndroidRuntime(  818): java.lang.RuntimeException: Unable to start activity
ComponentInfo{example.contentresolver/example.contentresolver.ContentResolverActivity}:
java.lang.SecurityException: Permission Denial: reading example.contentprovider.ExampleProvider
uri content://example.contentprovider.provider/words from pid=818, uid=10045
requires example.contentprovider.READ, or grantUriPermission()

Why am I getting this error?

You should define the permission first in the app that creates the ContentProvider, then use it.

<permission android:name="example.contentprovider.READ"
    android:permissionGroup="..."
    android:label="@string/perm_read"
    android:description="@string/perm_read_summary"
    android:protectionLevel="dangerous" />
